Trek Electric Bikes Review

eBicycles score

In terms of principles, Trek is firmly grounded in producing bikes with high-quality craftsmanship, aiming to bring the joy of cycling to a broader audience. The fact that the company has four electric bikes speaks for itself. 

Trek started back in 1976 as a subsidiary of Roth Corporation, an appliance distributor based in Milwaukee. The founders, Richard Burke and Bevil Hogg, began to manufacture steel touring frames with the aspiration to rival Japanese and Italian-made bicycles that were dominating the market at that time.

Just as its name suggests, Trek is fully committed to bringing its riders to great adventures and even promises to take them to the edge of the horizon.

It’s also fitting that their place of origin, Waterloo, is home to the Waterloo Driving Park Association, where spirited residents gather for some old-time tough and gritty bicycle racing.

Throughout its long history, Trek has been fueled by its determination to provide the best and the most rugged bicycles for the adventurous spirits that form part of their heritage.

Overview of Trek Electric Bikes

Trek Bikes produce premium quality bikes all around the world.

Trek was founded with an established goal of building high-end bikes for the United States. Back in the day, all the good bikes came from European brands. This inspired Richard Burke and Bevil Hogg to take matters into their own hands. The solution? To make their own brand of bicycles.

Three years after its foundation, Trek sales came close to the $2,000,000-mark.

Now, Trek Bicycle Corporation is one of the world’s biggest bike companies.

The company offers models designed for Road, Mountain, and Urban biking. Trek is also renowned for making the bikes that Lance Armstrong rode to his number of victories in Tour De France.

In terms of their electric bike portfolio, Trek covers a wide range of frames, from amiable town bikes to more powerful road bikes and mountain bikes. Currently, the company sells 24 of these bikes with a price range between $1,500 to $12,000.

What We Like About Trek Electric Bikes

It is a given that Trek is very well-known when it comes to building bikes. However, this doesn’t mean that every giant company doesn’t have kinks in its armor.

This section will talk about the pros and cons of Trek e-bikes. Here to highlight the things we like about them and the points to consider before buying their e-bikes.

Popular Trek E-Bike Models

The company has a ton of bicycles underneath its belt and a compelling product line, market value, and spec sheet.

Trek has been in the biking industry for a long time, but it didn’t hold back on innovating the e-bike scene. Here is a brief overview of Trek’s e-bike categories and what you can expect to see in each one.

Hybrid & Commuter Trek E-Bikes

If you’re looking to commute by e-bike, run errands around town, or just go for a leisurely ride with friends and family, Trek’s hybrid and commuter e-bikes are for you.

They’re split into three categories (City & Hybrid, Commuter, Recreational) and consist of multiple model lines:

• Dual Sport+
• Electra Go! E-Bikes

FX+ and Dual Sport+ model families are what you would call typical hybrid electric bikes with Class 1 speeds and rear hub motors. They are available with step-over and step-through frames and provide dynamic performance and upright riding positions.

On the other hand, Verve+ and Allant+ model lines are better-equipped city commuter bikes that cost a bit more but offer more in terms of features and speeds. They consist of Class 1 and Class 3 models powered by mid-drive motors and equipped with lights, fenders, rear racks, and even suspension forks on some ebikes.

Finally, Trek also offers Electra Go! electric bikes (Trek’s sister company), which consist of mid-drive and rear-hub drive e-bikes that fall into cruiser, city, and urban categories.

Trek Mountain E-Bikes

Trek’s electric mountain bikes provide ‘endless adventure’, as Trek puts it. The category consists of hardtail and full-suspension mountain e-bikes that will fit all different types of riders.

The selection includes XC bikes, trail bikes, and even enduro bikes. There are four model families you can choose from:

All of Trek’s mountain e-bikes are powered by trail-tough Bosch mid-drive motors and integrated batteries with up to 625 Wh of capacity. They have Class 1 capabilities and the batteries typically last up to 5 hours of continuous use.

The only downside of Trek’s e-mountain bikes is the pricing, as they typically cost between $6,000 and $14,000, though the Powerfly models are priced in the $3,000-$4,000 range.

Trek Road E-Bikes

Finally, Trek makes some of the best electric road bikes on the market, but also some of the most expensive ones.

They are famous for providing a natural riding experience and only supplementing power instead of taking over. Therefore, you’ll be able to ride further and enjoy road biking just as you would on a traditional road bike.

Domane+ is the only model family in this category, though it comes in around a dozen variations, including road and gravel capable builds.

These are Class 1 and Class 3 capable e-bikes with Fazua Evation or TQ e-bike systems. All models are built around lightweight carbon frames, come with drop bars, 1x and 2x Shimano and SRAM drivetrains, and powerful hydraulic disc brakes.

Therefore, if you want to explore more or keep up on fast group rides, one of Trek’s road e-bikes is for you, if you can afford it.

Trek E-Bike Classes, Motors, and Batteries

These bikes offer a lot of power and range from both their motor and battery.

The principle which the company is built upon is simple. That is to create a bicycle brand that is on par or even more significant than its European and Japanese counterparts back then. Now, they are one of the biggest bike companies in the whole world, so their grit and drive really paid off.

Trek is all about creating reliable bicycles that could take their customers to the next level of fun and enjoyment.

The company’s formula to success lies at their rigid standard of quality when it comes to their bikes. It ranges from steel, alloy, and carbon fiber, ensuring that it can take on any punishment it might receive when riding. They also didn’t hold back in choosing each component, as evidenced by their top-notch Bosch electric motors and Shimano parts.

When it comes to selling, the company won’t have any problems catering to your needs as they distribute their bicycles worldwide. What’s more? They even have 1,700 dealers in the U.S. alone. Their website also allows you to see the store closest to you, where you can view, test, and purchase their bikes.

Reliability and Durability

Trek Bikes use only the best quality materials so that their products can handle extreme terrains and any kind of weather.

Trek began with a vision from the two founders to build the best bicycles that the world had ever witnessed.

Thus, the company’s strict observance of the highest possible craftsmanship quality was born.

The company’s collection of bicycles typically receive rave reviews for their build quality. This applies to even their entry-level bikes, which at the price tag they’re sold at, isn’t always known to have the most premium components. Even if their price range generally makes their bikes a luxury, everything about it feels premium and durable when you get your hands on it.

As a testament to their bike’s quality, one Quora user shared that he almost managed to travel across Canada by riding an entry-level 1993 Trek 820 Antelope. This devotion to their founder’s vision endeared many cycling enthusiasts to the company and brand.

How to measure a bike frame: our complete guide to sizing a bike

Fundamental measurements so you can compare frames like-for-like

Simon Bromley / Immediate Media

Paul Norman

If you’re thinking of buying a new bike, or a first bike, understanding the key measurements that define your frame is important to ensure you get a machine that fits you and works for the type of riding you intend to do.

And if you’re planning to rent a bike, it’s useful to know your frame’s key measurements, so you can make sure your rental will be comfortable to ride and can be adjusted to fit.

Not all manufacturers measure frame sizes in the same way, so you need to look at a few fundamental measurements to ensure you’re comparing apples with apples.

Read on to find out how to size up your road bike or mountain bike frame to ensure you get the right bike fit . Also check out our comprehensive guide to mountain bike geometry , which tells you how these measures affect handling; even if you’re a roadie, most of the measurements are still as significant.

We’ve also got advice on how to choose the right size frame for road bikes and mountain bikes and specific advice for choosing a women’s bike .

Bike geometry measurements

We’ll tell you below how to measure the key numbers that define your bike. But first, here’s a quick rundown of those numbers:

• Top tube length: the horizontal distance between the centreline of the head tube and seatpost
• Seat tube length: the distance between the centre of the bottom bracket and the top of the seat tube
• Reach: the distance between the bottom bracket and the top of the head tube
• Stack: the vertical distance between the bottom bracket and the top of the head tube
• Wheelbase: the distance between the front and rear axles
• Chainstay length: the distance between the bottom bracket and rear dropout 
• Front centre: the distance from the bottom bracket to the front axle 
• Seat tube angle: the angle of the seat tube in relation to the ground
• Head tube angle: the angle of the head tube in relation to the ground 
• Bottom bracket drop: the difference between the height of the wheel axle and crank axle
• Bottom bracket height: the distance from the ground to the bottom bracket

What you’ll need to measure a bike frame

To measure a bike frame you will need four tools:

• A tape measure
• A clinometer to measure angles (there are free smartphone apps you can download)
• A long spirit level (or you can use the clinometer app and a straight piece of wood)
• A plumb line (or you can improvise with string and a couple of blobs of Blu Tack)

Most bikes, whether road or mountain, are now measured in metric units, but you may find some manufacturers that still size mountain bikes in inches. Some brands, such as Moots, even mix the two.

We highly recommend you stick to metric units to keep things consistent. If you really must, you can always divide centimetres by 2.54 to switch to inches.

You will usually be able to find a geometry chart for all sizes of a current frameset on a maker’s site. If your bike is still a current model, it’s worth taking a copy of this because it will be more accurate than your measurements and likely a handy reference down the line.

How to measure top tube length

Once, bikes all had horizontal top tubes. Now many bikes’ top tubes will have a slope.

If you look at a bike geometry table, it will usually include the real top tube length. But for a consistent measure, regardless of the top tube angle, you need to measure the horizontal top tube length, called the effective top tube length or virtual top tube in many geo charts.

That’s the horizontal distance between the centreline of the head tube and the centreline of the seatpost. Measuring it correctly will mean using your spirit level or the clinometer app, to ensure your measure is really horizontal.

Many manufacturers size road bikes by top tube length. That’s not true of mountain bikes, where the frame size is usually marked S, M, L, etc. That’s a system used for some road bikes too: Merida’s road bikes go through S, S/M, M/L and L.

Of course, this measurement is up to each brand's interpretation – Ridley’s size-S frames have a top tube of around 54cm, which is equivalent to many brands’ size-medium frames.

It’s worth noting that not all brands measure virtual top tube length in the same way either.

Colnago, for example, records the horizontal distance from the head tube to a vertical projected up from the top of the seat tube, so it doesn’t take account of the further backward projection of the seatpost and its numbers will come out smaller than other makers’. A 50s Colnago is equivalent to a 54cm top tube.

How to measure seat tube length

Seat tube length is the straight-line distance between the centre of the bottom bracket and the top of the seat tube.

Again, it’s trickier than it sounds: some bikes such as the Trek Madone have a considerable extension of the seat tube above the top tube junction, while others use a seatmast, so it’s difficult to compare with an alternative’s dimensions.

Plus, mountain bikes in particular often have a kink in the seat tube, so you don’t want to follow the line of the tube itself, which will be longer.

Line up your straight edge with the bottom bracket centre and the top of the seat tube and measure along this, if you’re not sure you’re following the right line.

How to measure reach and stack

So we’ve seen that top tube and seat tube lengths are a bit of a minefield if you want to compare frames. For more consistency, most manufacturers will now show reach and stack values for their bikes.

These have the advantage of being independent of frame design and measure the perpendicular distances between two key contact points: the bottom bracket and the top of the head tube.

We’ve published a more detailed explanation of why reach and stack are important here .

In brief, the reach is the horizontal distance between the two. To measure it, you’ll need your spirit level again.

Attach a plumb line to the end of the level. If you’re using Blu Tack, make sure the blob at the end of the string is fairly symmetric and your string hangs down straight, otherwise your measure may be off.

Align the top edge of the level with the centreline of the top of the head tube. Then move the level back and forward until the plumb line intersects with the centre of the bottom bracket spindle. Now just measure the distance between the top of the plumb line and the head tube and you’ve got your reach.

Another option is to push your bike up against a wall, measure the distance to the top of the head tube and the distance to the bottom bracket, then subtract one from the other. You’ll still need to make sure your measurement is horizontal though.

The stack is the vertical distance between the bottom bracket and the top of the head tube. So once you’re set up to record your reach, you should also be able to measure your stack, following the plumb line.

An alternative method is to measure the vertical distance from the ground to the top of your head tube, then measure the height of your bottom bracket from the ground and subtract this.

Both reach and stack are quite fiddly to capture. You’ll probably need a second pair of hands if you use the plumb line method and it’s worth repeating to ensure you’re consistent.

How to measure wheelbase

Your frame’s wheelbase is the distance between the front and rear axles. It’s a key determinant of a frame’s ride quality and will vary with frame size too.

It’s fairly easy to measure, although you need to set the fork straight ahead or your measurement will be incorrect.

Like reach and stack, it’s worth repeating the measurement several times to make sure you get the same number. Accuracy will also be increased if you measure the wheelbase on both sides of the bike and take the average because this will compensate if the fork is not quite straight.

How to measure chainstay length

Chainstay length is one of the two components that make up your wheelbase and, again, contributes significantly to your frame’s handling characteristics. A frame with shorter chainstays will typically feel more lively than one where the stays are longer.

The chainstay length is the straight-line distance between the centre of the bottom bracket axle and the centre of the rear dropout, so it’s fairly easy to measure with a ruler.

How to measure front centre

The other component of the wheelbase is the front centre. That’s the equivalent of the chainstay length but measured from the axle to the front dropout.

Again, it affects handling, as well as toe overlap with the front wheel. It’s not often quoted by bike makers, but BMC, for example, shows it on its geometry charts.

Note that the wheelbase is not the sum of the chainstay length and the front centre, because neither of these is measured horizontally.

How to measure seat tube and head tube angles

The seat tube and head tube angles are two of the most important factors in determining handling, with more upright tube angles typically leading to more nimble handling. Your clinometer app will come in useful here.

If you’ve got a straight seat tube, you can measure the seat tube angle by lining up your smartphone and reading the number from the clinometer app. Make sure your bike is vertical and standing on a horizontal surface for an accurate reading.

If there’s a kink in your seat tube, you’ll need to use a straight edge to follow the line between the bottom bracket shell and the top of the seat tube, then line up the phone with this.

Most newer bikes will have tapered head tubes, so the angle of the front of the head tube will not be the same as the angle of its centreline.

You can get close to the latter by holding your phone at the angle of the centreline, or by using a straight edge to line up with the centres of the top and bottom of the head tube.

If you have straight fork legs, without an angle at their crown, the angle of the legs will be the same as the head tube angle, so you can measure this instead. Again, it’s important to have the bike standing vertically.

You can also measure head tube angle by lining up the clinometer with the steerer extension above the head tube.

How to measure bottom bracket drop

The bottom bracket drop is the difference between the height of the wheel axles and the centreline of the crank axle.

You can measure it by finding the height of the rear axle and the height of the bottom bracket, then subtracting one from the other. It’s another key measurement quoted by bike brands on their geo charts.

How to measure bottom bracket height

Finally, the bottom bracket height is the distance from the ground to the centre of the bottom bracket shell. So that’s quite easy to measure, although be careful to keep your bike straight upright for an accurate reading.

Unlike bottom bracket drop, it will be affected (slightly) by your tyres too, so inflate them to your usual running pressure.

Now you’ve got all the measurements you need to size up your frame, and help with any purchasing decisions in the future, whether that's a new or second-hand road bike, commuting bike or gravel bike . Keep your numbers somewhere safe though: you don’t want to have to repeat the process.

Review: Trek Fetch+ 2

If you buy something using links in our stories, we may earn a commission. This helps support our journalism. Learn more . Please also consider subscribing to WIRED

One of the things that can be intimidating about buying a cargo ebike is how unfamiliar they feel. Whether a bike is designed with weird geometry and wheel sizes or odd features for heavy hauling, every ride can feel unfamiliar.

For traditional cyclists who want to haul a grocery store trip’s worth of groceries home but don’t want to mess with technology they’re unfamiliar with, the Trek Fetch+ 2 is a decent option. It’s more expensive than some of our favorite alternatives, but it has an easy-to-ride step-through design, well-made components, and great plastic buckets (and other accessories) for storage.

There are bikes with more advanced features for the money, but even after I spent a summer riding the Fetch+ 2, it barely needed a tune-up. For a modern cargo ebike with a classic cargo bike maintenance schedule, it might be worth spending a bit more cash.

On the Road

The Fetch+ 2 is the smaller of Trek’s two latest cargo ebikes, which includes the box-fronted Fetch+ 4 ($8,500) , which is more oriented toward toting around dogs and children in between groceries and beer.

The Fetch+ 2 instead is a more traditional step-through cargo bike that employs a myriad of attachments, most notably two plastic panniers that hang off an extended rack on the rear. You can get a padded seat cover for the rear to let friends hold on and ride, or mount a couple kids’ seats behind you, but I’d still probably use this bike more for errands than transporting little ones.

As an objet d’art , the bike is simple and unassuming, which is ideal for a bike this expensive. The battery is integrated into the frame, but a sizable bulge means nobody will fail to notice it's an ebike. You can get it in three colors. I liked the black of our review unit, but the bright blue would probably be my choice if I was buying one.

While much of the bike will be familiar to anyone who has ever seen or contemplated a cargo bike, Trek really gets the geometry and style of this bike correct as far as making it very usable for many tasks. Even the dual-sided kickstand pops up and down with remarkable ease (shockingly rare on other large ebikes I've used). I particularly enjoyed using the rear panniers for hauling flats of berries and other easily squished items that tend to rattle around in softer panniers.

The panniers fit a ton of stuff; I was able to get four full-size grocery bags spread between the two black plastic totes. I like that they had little plugs in the bottom that you could feasibly use a plastic bag to cover and then fill them with ice and drinks.

I spent a couple months using the Fetch+ 2 as my primary bike, and came away much more impressed than anticipated, given the specs and the price.

On paper, this is an expensive ebike to have pretty standard mid-drive cargo bike specs. The 85 Nm Bosch motor and 500-wH battery are good for 20-plus miles a day loaded down in any city, but they’re not better than models like the larger Xtracycle Stoker, which has the same torque and a 630-wH battery for $4,999. The Trek also doesn’t have a carbon belt drive and variable transmission, which we consider the best (and easiest to maintain) shifting mechanism for cargo bikes.

The more traditional chain-and-gears drivetrain and no suspension make this a less comfortable and more difficult-to-maintain bike than favorites like the Tern GSD ( 8/10, WIRED Recommends ), which costs about the same. I have to say, I was expecting the difference in riding experience to be more severe. The fatter-than-usual 20 x 2.35-inch tires of the Trek absorbed potholes better than other suspensionless bikes. It also stopped just as well as its competitors, thanks to hydraulic disc brakes.

Mid-drive cargo bikes are much better than their rear-hub counterparts, especially when toting larger items or smaller humans, because they allow you to get more torque to the wheels, and provide a more traditional riding experience. I never found myself lacking for power, though I did crunch through the gears a bit when starting on a hill.

The Fetch+ 2 rides really well, with a solid frame and no creaks or sketchiness of any kind (as picked up from my local Trek dealer, another plus of ordering from the brand), and I really liked how bright the built-in lights were when riding home from soccer games and band practices at night. The fat wheels were easy to turn, giving this a turning radius similar to a non-extended ebike when I was making U-turns in the city. It also has a built-in phone mount with a wireless charger, which makes it really nice for using a map app to cruise to unfamiliar places.

It’s not a fun bike to ride in the traditional sense; it’s not the fastest or the most comfortable, but it is satisfyingly robust and confidence-inducing. In my months of riding, I never had a single issue with the bike. That’s unusual given the state of some of the roads I often took the Fetch+ 2 on the side of, and a testament to Trek's great build quality.

If I was a longtime Trek owner and interested in getting into cargo ebikes, I’d certainly give this line a look, with the understanding that I might find something I like better from Tern, Xtracycle, or another brand for the same price—or something from Rad Power Bikes or another more affordable direct-to-consumer manufacturer for less. It’s a well-made bike that does what it claims to do, but it’s on the spendy side.

It is a bit hard to come by, at least in bike shops around my hometown of Portland, Oregon. If you’re interested in this one for your treks around town, I’d make sure to call ahead for a test ride. If you want a familiar-feeling bike with all the frills of electrification, it’s worth a spin.

Your Bicycle Size Guide

eBike Size Chart (Tire, Frame, Motor, & Battery Size Guide)

I know, Electric bike sizing can be quite confusing. Many e-bikes are available in ONE size that fits all, while some are designated with general sizes, such as SMALL or MEDIUM, and then there are 24-inch and 26-inch e-bikes.

So, which size electric bike do I need? If you are a noob, you might be already scratching your head. Don’t worry, I’ll break down all the things you need to know about e-bicycle’s frame, motor, wheels, and battery sizes.

Manufacturers mostly measure electric-assist bikes based on seat tube length (frame) just like they measure traditional bicycles. However, some manufacturers measure by the diameter of the wheels. There isn’t a huge difference between the geometry of non-motorized and motorized bicycles.

E-bike measurement and types

To make things more simpler and help you find the right fitting and comfortable e-bike, first understand the basic geometry, measurement, and types of electric bikes.

Measurement

• Technically, electric road bicycles are measured by frame size in centimetres, while electric mountain ebikes are sized in inches.
• Brands like Aventon , Scott , Trek , and Marin often present their e-bikes in rough sizes like XS, S, M, Regular, and L.
• But, most e-bike manufacturers label their bicycles according to wheel/tire diameter such as 24″, 26″, 27.5″, etc.
• You may also find an electric bicycle in only one size which fits riders of different heights.

Types of e-bike

• Cruiser /commuter ebike: Designed for leisure, commuting, and recreational riding on flat surfaces. Most cruiser electric bikes come with upright frames, higher handlebars, rear racks, baskets, fenders, and wide tires and saddles.
• Off-road/mountain ebike: Best for riding on all terrains. Whether you are rolling over rocks, hills, sands, or paved roads, an electric MTB is great for adventurous rides.
• Road e-bike: Sports drop handlebar and step-over frame. It is made for speed – going faster on plain roads.
• Folding electric bike: As the name suggests, folding bikes can be easily folded and unfolded. They are compact and portable and you can take it anywhere you go and store at small spaces like car trunk.
• Cargo e-bike: Comes with strong frame and it can bear heavier weights. You can carry luggage, packages, parcels, and so on.

eBike size chart by wheels/tire

Most of the brands on Amazon like Heybike , Ancheer , Totem , and Totguard display or size their electric bikes by wheel diameter in INCHES. Below is the standard size chart of cruiser, commuting, mountain, and road electric e-bikes .

Note: Be aware that brands often have their own sizing systems. Unlike conventional bicycles, most small wheeled ebikes are foldable and come with adjustable saddle height. Thus, they fit all the adults of average heights.

Electric mountain bike size chart for men/women

Most established brands like Bianchi , Specialized , Orbea, Yeti Cycles , and IBIS use a simple XS/S/M/L sizing system. This makes it easier for the consumers to decide which ebike size is best for them.

Road eBike sizing for men/women

Battery-powered road bicycles are lighter and have downward curled handlebars, thin tires, and shallow wheels. They are measured in centimeters and have higher stand-over heights, so measuring your inseam length (inside leg) is important here . Make sure there is 1 – 2 inches gap between the top tube and your crotch (inseam length + 1″/2″) .

Electric bike motor size chart

Electric bicycles come with different motor power levels, such as 200 watts, 250 watts, 350 watts and so on. But, what ebike size motor I need? Well, it depends on your riding style, weight, budget, the type of terrain you intend to ride, and the commuting distance.

Bosch , Shimano , and YAMAHA are some of the established players in the electric-powered bike motors’ industry. Anyway, below is the ebike motor power chart:

Personal note: For casual riders, a 250W or 350W electric bicycle is more than enough for leisure riding and commuting on roads, flat land, or small hills. If you are like Dominic Toretto or a 300 pounds dude, you’ll want a 500W or 750W motor.

eBike battery size chart and range

Battery capacity (size) is one of the most important specifications you should look for in an electric bicycle. It tells you how fast and far you can go on a single charge. Typically, most e-bikes come with either 36-volt or 48-volt battery specified by Amp-Hours (Ah) from 10 Ah to 21 Ah. The more the Amp-Hours, the more energy the battery can provide. More energy means you can cover longer distance. Right?

Anyway, it is difficult to calculate the range of ebikes because of many factors such as rider’s weight, terrain type, riding style, wind condition, etc. Below is the ebike battery size and the estimated range:

Rough calculations based on –

• Wh = watt-hours ( volts x amp hours = watt hours )
• Moderate pedal-assist mode
• Low range – 20 Wh per mile
• High range – 15 Wh per mile

Bike Size Chart: How to Choose the Right Bike Size? (GUIDE + Calculator)

This guide will teach you how to choose the right bike size using bike size charts and other methods. It covers the most popular bike types, including hybrids/city, mountain, and road bikes .

Use this interactive calculator that recommends a bike size based on your inseam length and bike type. Alternatively, choose the bike size based on one of the three methods explained below .

Bike Size Calculator

DISCLAIMER: Please remember that the calculator does not consider your height, which may affect your bike size.

What Bike Size Do I Need?

To determine which bike size you need, use one of the following methods, sorted from the simplest to the most complex. Remember that simpler methods are less precise, while more complex methods offer greater accuracy.

Method #1: Bike Size Based on Your Height (The Easiest Method)

This is the easiest and quickest method to select a bike size. All you have to do is compare your height with the general bike sizing chart below .

However, this method doesn’t consider the type of bike, so it may not be as accurate as the methods below. As a result, the bicycle may not fit you perfectly.

Method #2: Bike Size Based on Your Inseam Length and Bike Size Chart

This is probably the best bike sizing method for most people. It is based on measuring your inseam length at home and comparing it with a bike size chart .

Once you measure the inseam length, use it to select the bike size. Most bicycle manufacturers use seat tube length and other details, including the standover height, in their bike size charts.

The standover height is the distance from the ground to the top of the top tube.

If your inseam length is shorter than the standover height, the bike is too big for you.

The clearance, which is the difference between your inseam length and the standover height, should be around 1 to 2 inches.

This clearance is essential to prevent injuries caused by sudden or emergency stops.

IMPORTANT NOTES

• The inseam length for choosing a bike size is measured differently from that used for buying pants. Learn more
• To choose the most accurate bike size, always compare your measurements with the manufacturer’s bike size chart for your bike type.

Hybrid Bike Size Chart

Depending on the manufacturer, hybrid bikes usually come in descriptive sizes (XS-XL) and heights. However, you may still encounter all three types of size designations – in, cm, and descriptive sizes.

And here is a helpful infographic:

Mountain Bike Size Chart

The size of mountain bikes is typically measured in inches (13″, 19″, etc.) or descriptive sizes (XS-XL).

Generally, smaller mountain bikes usually come with 27.5″ wheels, while larger ones have 29″ wheels.

And here are the sizes in the picture:

Road Bike Size Chart

Road bike sizes are usually given in centimeters or descriptive sizes.

You should take extra care when choosing the size of your road bike. Road cycling is a discipline in which you spend long hours in the saddle, so selecting the right bike size is crucial.

It’s also essential to choose the right type of geometry. For instance, endurance geometry road bikes (where you sit more upright) are suitable for beginners, while aggressive (sporty/performance) geometry requires a certain amount of flexibility.

The following road bike size chart also applies to cyclocross and gravel bikes .

And again, an infographic:

Method #3: Calculating the Bike Size

As we know from Method #2 , bike size is determined by the length of the seat tube. To effectively use this method, you must know the length of your inseam ( learn how to measure it correctly ).

To calculate the size of your next bike, use the following formulas depending on the type of bike you want to buy.

To calculate the size of your next bike, use the following formulas depending on the type of bike you want to buy. ( Source )

• Inseam Length (cm) × 0.685 = Hybrid Bike Size (cm)
• Inseam Length (cm) × 0.225 = MTB Bike Size (inches)
• Inseam Length (cm) × 0.665 = Road Bike Size (cm)

1 in = 2.54 cm 1 cm = 0.39 in

After you receive the result, round it up to the nearest whole number. This will match the bike size charts above with a slight deviation.

Example of calculating the MTB Bike Size:

Your inseam length is 33 inches, and you want to buy a new mountain bike. Let’s do the math:

Convert cm to inches: 33 inches × 2.54 = 83.8 cm Calculate the bike size: 83.8 cm × 0.225 = 18.8 ≐ 19 inches

The size of your new mountain bike should be 19 inches .

Example of Calculating the Road Bike Size:

Your inseam length is 70 cm, and you want to buy a new road bike:

70 cm × 0.665 = 46.55 cm ≐ 47 cm

As you can see, your new road bike size should be 47 cm .

How to Measure the Inseam Length?

To measure your inseam length, follow these five simple steps or watch the video below:

• Prepare a 0.75 to 1-inch (1.9-2.5cm) thick book and a tape measure.
• Take off your shoes and stand with your back to the wall.
• Put the book in your inseam, firmly pull it up, and hold it with your tights. Make sure the book is pressed against the wall on one side.
• Measure the length from the top of the book to the floor.
• Take the measurement.

NOTE : The inseam for choosing the right bike size is different (a few inches longer) from the inseam used to choose the pants’ size. Remember that inaccurate inseam length may affect the recommended bike size.

Once you measure your inseam length (and eventually also your height), you can compare it with the bike size chart of the specific bike type. Based on it, you can choose the correct size.

Choosing the correct bike size is easy when you know how to do it. You can use the bike size calculator that recommends a size based on your inseam length and bike type, or try one of the three methods I explain:

• The first method is simple but not very accurate. You only need to know your height and compare it with the universal bike size chart.
• The second method is the most accurate. First, measure your inseam length and decide what bike type you want. Then, compare your inseam length with the hybrid, MTB, or road bike size chart, and you’ll have the right size to buy.
• The third method requires some math but is more accurate than the first. You need to know your inseam length and use special formulas to calculate the size of your next hybrid, mountain, or road bike.

Choosing a Bike Size FAQ

I remember trying to choose the size for my first road bike. I asked a cycling forum for advice because I was stuck between two sizes. The forum members gave me some tips, but most were too complicated for a beginner like me. They suggested that I check the bike’s geometry, but I had no idea how to do that or compare it to my body measurements. So I asked my friend, who has been selling bikes for over 10 years at a local bike shop. He gave me the following advice: “It depends on what kind of rider you are. If you’re a recreational rider, go for a bigger frame. It’s more comfortable because you won’t have to raise the saddle as high as you would with a smaller frame. This will give you a more upright position, which is more comfortable. However, if you’re serious about cycling and want to race, a smaller frame will give you a more aerodynamic and aggressive position. Smaller frames are also more agile and lighter.”

There are several ways to choose the right size bike, but in this guide, I’ll explain three methods: 1. The first method is based on your height and a universal bike size chart. It’s the simplest but not the most accurate method. 2. The second method uses your inseam length and specific bike size charts for hybrid, mountain, and road bikes. It’s the most accurate method for most people. 3. The third method involves calculating the bike size using your inseam length and a unique coefficient that varies based on the bike type. It’s more accurate than the first method but not as accurate as the second. You can also use an interactive calculator that recommends bike size based on your inseam length. I recommend reading the entire article to better understand each method and decide which one works best for you.

Choosing the right bike size is crucial, not only for your comfort but also for preventing health problems. If your bike doesn’t fit you properly, you may experience pain in various body parts, such as your lower back, neck, and hands. ( Source ) According to Physio-pedia.com , there are four essential components of a good bike fit: correct foot position, saddle height, stem length, and handlebar position. However, remember that if your bike is two sizes too small or too big, you won’t be able to achieve a proper bike fit. Therefore, learning how to choose the correct bike size is important. You can avoid discomfort and potential health issues by selecting the right bike size. So, take the time to find the perfect fit for you.

If you have ordered a new bike the wrong size, I recommend returning it as soon as possible. Most online retailers allow returns. If you ride the wrong size bike, you risk injuring yourself (e.g., overloading certain muscles) or not being comfortable in the saddle. It also happens that even experienced cyclists ride the wrong size bike, so they often fail to adjust it to their liking.

It’s a bit complicated. The answer is mostly no, but there are some exceptions. Let me explain. Many people ask this question. But it is a wrongly asked question because bike size doesn’t depend on age. Our heights vary greatly, so a 19-inch bike may suit someone even if they’re not the “correct age” for it. The correct question is: “What height and inseam length is a 19-inch bike for?” With this information and the bike chart for the specific bike, you can determine who the bike is suitable for. Read the entire guide on choosing the right bike size for more information.

A 26-inch bike refers to a bicycle that uses 26-inch wheels. These wheels are commonly found on kids’ bikes, but some adult (mountain) bikes also use them. Nowadays, 27.5-inch and 29-inch mountain bikes are becoming more popular because they offer better comfort and speed. If you’re shorter than 5’0″ (150 cm), a 26-inch bike may be a good choice. However, if you’re taller, I recommend choosing a bike with at least 27.5-inch wheels. Check out this guide to learn more about selecting the right bike size.

Bike Frame Size Chart

Trek Bike Size Charts

By bicycle type:

Trek Mountain Bike Size Chart

• Trek Road Bike Size Chart

Trek Hybrid Bike Size Chart

By bicycle model:

• Speed Concept
• Supercaliber

These charts are based upon official Trek website sizing guide for hybrid & city, MTB and road bicycles. Take the charts below as a general guide and check the sizing calculator on the Trek's website for official results.

The Trek bike size chart, taking into account both height and inseam measurements, offers cyclists a comprehensive guide to selecting the perfect bike size for their body proportions. By considering both of these factors, riders can ensure an optimal fit and maximize their comfort and performance on the bike. Height and inseam helps determine the frame size. This chart enables cyclists to find the ideal frame size, for a comfortable riding position. With the Trek bike size chart by height and inseam chart, cyclists can confidently choose a bike that suits their body measurements and enhances their cycling experience.

Most important difference in mtb frames is the frame full suspension or hardtail. Trek offers bikes from both categories and have even more mtb bike types to offer.

Trek Road Bike Sizing

Trek road bicycles are being made in four different categories, depending on the riders needs. Aero road bikes have excellent aerodynamics and they are the choice for riders who are looking for speed and performance. Lightweight road bikes are excellent climbers and all-around bicycles. Endurance road bikes are built for those riders who spend a lot of time in the saddle, their intended use is to make riders as much as comfortable as possible during the long hours of riding. Gravel road bikes are for use on gravel and dirt roads.

Hybrid, as name states, brings a mixture of a road bike and mountain bike. They tend to have narrower tires than mountain bike and usually they have a front suspension (but sometimes comes with rigid fork too). Hybrid frames falls into the specific category between road and mtb bikes. They never come with drop bar, which differs them from road bicycles. They are ok choice for commuting and excellent one for casual fitness riders.

City bikes, as their name say, are intended for urban use on paved, asphalted roads. Main use is for transport and not for recreational riding.

Bike Sizing Guide: What Size Trek Bike Do I Need?

Written by  Gary Johnson / Fact checked by  Henry Speciale

Are you looking for a bike to buy and asking yourself “what size Trek bike do I need?”

Trek bike sizing is very straightforward and varies by type.

For example, mountain bikes follow a unique method called alpha sizing that uses designations such as small, medium, or large. Using this system, a 5’3” to 5’7” tall person can use a 17.5” frame size.

On the other hand, Trek road bike sizing takes into account the inseam length.

If you want to get on the road or hit that trail with your ideal two-wheeler, check out our sizing guides below.

Table of Contents

1. Trek Mountain Bike

2. trek road bike, 3. city & hybrid bike size chart, things you can consider before choosing a trek bike size, helpful tip, trek bicycle sizing guide.

Trek bikes are comfortable and easy to ride, making them excellent for beginners. They also come in different dimensions, so you should find one that fits you perfectly.

Whether in inches or cm, our Trek bike size chart will help you match your height with the appropriate vehicle.

Unlike other brands, Trek bikes have upgraded their MTB sizing with alpha classifications to remove guesswork for customers.

You may find that your chosen model has some and not all of the sizes in this Trek MTB size chart. In that case, branch out and look for XS and XXL options if the Trek M/L frame size doesn’t fit you.

Note that the women’s bike size chart also uses the alpha sizing guide for their line of women’s mountain bikes though the height requirement is slightly different for each size.

Did You Know

The Trek Marlin 5, which is a popular trail mountain bike, uses the alpha sizing chart, but its size is not limited to XS – XXL only! Trek also offers an XXS with 26” wheels for this MTB type.

Trek has given us 4 categories when it comes to road bicycles. These include:

• Aero – The best aerodynamics for speed and performance
• Endurance – Provides comfort perfect for long hours of riding
• Time Trial – Speed-focused bikes with unique designs
• Climbing – Lightweight bikes excellent for uphill climbing

Designed to be a mixture of road and mountain bikes, Trek hybrid bicycles are best used for casual rides and commutes.

What size bike should I get? What does “size” really mean? And what is the best way to find the correct model for yourself?

There are usually FOUR different aspects that you must consider and have a good idea about.

Riding Style

Do you want to ride your bike for fun or use it for racing and exhibition? Regardless of your budget, it is important that you consider the type of biking you want to do. Some people prefer to ride in the city, while others prefer to cycle off-road.

Trek bikes come in various sizes depending on the vehicle’s discipline, since some frames have different geometry to provide the support their riders need.

Rider Height

Most bicycle models come in different sizes for different body types so that they fit most people well.

The height of a person, when measured from head to toe, can help determine the bike size that would match them. This is because taller people have longer upper and lower extremities compared to shorter people, which means they will need different sizes of bikes in order to ride comfortably.

Inseam Length

After careful deliberation with the above two factors, the frame size is then ultimately determined by your inseams or the distance from your crotch to the bottom of your leg.

You should take this into consideration because it will determine how much room there is between your feet and handlebars when sitting on the saddle comfortably.

Practical Use /Test Ride

Last but not least, once you have chosen your bicycle size and Trek model, test out the bike with at least a short ride. This will let you assess the balance and comfort of the chosen vehicle.

Whether you ride recreationally or professionally, you cannot choose blindly. First, bikes are expensive, and second, you must buy the correct product to use it for a long time.

If you’re done with our Trek frame size chart, Trek’s online website also has a unique feature that helps you select the correct frame size. You can try their bike finder, which asks for your riding style, height, and even inseams before arriving at a recommendation.

In case you haven’t noticed, there is a lot of variation in bicycle sizing, and looking for the size I need for my height was not a walk in the park.

Well, I hope our guide answered your question about what size Trek bike do I need. Should you have any more questions, send us a message.

Choosing the right bike size is essential for comfort, efficiency, and preventing injuries.

While test riding a bike is the ideal way to gauge fit, it’s not always practical, especially with the often better deals found online compared to local bike shops.

The good news is, you DON’T NEED TO test ride a bike to ensure a good fit. 

If you know your height and inseam length, you can get the right size by using a bike size chart.

However, this is where things get slightly more complex.

Bike manufacturers may use different sizing standards, such as centimeters and inches, or sizing labels such as S, M, L, XL. Sizing methods also differ based on bike types—road, mountain, and hybrid bikes are not sized in the same way.

If you’re starting to feel overwhelmed, don’t worry. Keep reading below and we’ll make things a lot clearer.

Should You Trust S, M, L, XL Bike Size Labels?

Many manufacturers also use size labels such as XS, S, M, L, and XL. These labels are becoming more common because they simplify things, but they can sometimes be vague and misleading.

Due to the lack of standardization across brands and bike types, you should avoid relying only on bike size labels when choosing the right size. Their dimensions may vary from one brand to another.

Letter-based size labels offer a good starting point but should be cross-checked with other methods.

For example, an L-sized Trek road bike may have a 56 cm seat tube length, while a Giant’s L-sized road bike may have a 58 cm seat tube length.

Therefore, you can use these labels as a rough guide, but make sure to also refer to a bike type-specific size chart (such as the ones below) or the manufacturer’s sizing chart for the specific model you’re interested in.

What and How to Measure?

To be able to use a bike frame size chart and correctly size a bike, you need to know two measurements: height and inseam (inside leg) length.

Why does inseam length matter?

The inseam length is important to ensure you get a bike with an appropriate standover height. This is the distance from the ground to the top of the bike’s top tube.

Ideally, to prevent injury and improve comfort, there should be a one-to-two-inch clearance between your crotch and the top tube when standing over the bike.

What you’ll need:

• A tape measure
• 30 seconds of your time

Measuring your height  is super simple. All you need to do is:

• Stand straight against a wall with your feet together.
• Place a book on top of your head, making sure it’s horizontal with the floor.
• Measure the distance from the ground to the point where the book and the wall meet.

Measuring your inseam is even simpler:

• Just stand against a wall with your shoes off and feet hip-width apart.
• Measure the distance from the ground to your crotch.
• That’s it!

With these two measurements written down, you’re pretty much all set to find the perfect bike size for your height and inseam.

Adult Bikes Are Sized by the Frame

Adult bikes are primarily sized by the frame; or to be more specific, they are sized by the seat tube length .

This is the vertical distance from the center of the pedal axle (the bottom bracket) to the top of the seat tube—it’s often listed in measurements like 52 cm, 54 cm, 56 cm , or 17 inches, 19 inches, 21 inches .

While this measurement is a good starting point, it doesn’t tell us all that we need to know—it determines the height of the bike, but not its length, also known as reach.

Why Does Reach Matter?

To really dial the fit, you should also consider the bike’s reach , which refers to the horizontal distance between the bottom bracket and the head tube.

Reach tells you how far you have to stretch to reach the handlebars and is especially useful if you’re in between two sizes.

A shorter reach means you’ll be sitting more upright when you’re riding—perfect for comfort on longer rides.

A longer reach means you’ll be more stretched out on the bike—ideal if speed and aerodynamics are your priorities.

Men’s vs. Women’s Bike Sizing

In adult bike sizing, the distinction between men’s and women’s bikes often comes down to marketing rather than significant sizing and design differences.

Therefore, the bike frame size charts below are suitable for all riders , regardless of gender.

Even though some brands offer models specifically labeled for men or women, and a few brands manufacture women’s bikes only (such as Liv or Juliana), the differences compared to unisex bikes are miniscule.

Men’s and women’s bike sizes are largely similar, with only minor differences driven by marketing. Most bikes are unisex!

These often include slightly different proportions between the bike’s stack (vertical height) and reach (horizontal length), which are negligible unless you’re a professional rider.

For example, women’s models might have a shorter reach compared to the stack to accommodate what some manufacturers perceive as average body proportions.

However, as body types differ among individuals, a women-specific bike might not automatically provide a better fit for every woman. Similarly, some men might find that a women-specific model fits them better than a men’s or unisex model.

Kids’ Bike Sizing: Sized by Wheel Diameter

Unlike adult bikes which are measured by frame size, kids’ bikes are determined by wheel size , simplifying the selection process.

Wheel diameters on kids’ bikes typically range from 12 inches to 26 inches , increasing in two-inch increments. This means that a 12-inch kids’ bike has 12″ wheels, a 14-inch bike has 14″ wheels, and so on.

Manufacturers then use these wheel size measurements to provide size recommendations based on a child’s age, inseam length, or height.

For example, a 12-inch bike might be suggested for children ages 3 to 5, with specific height or inseam measurements to further dial the best fit.

Many manufacturers provide additional information such as standover height and min/max seat height , which allows parents to get a better fit by relying on the inseam length measurement.

While wheel diameter and age can give a general idea of the right bike size, incorporating inseam length in the equation is advisable for the perfect fit.

While most adult bikes are sized by the frame, specifically by the seat tube length, sizing standards can differ slightly based on bike types.

For example, road bikes are typically measured in centimeters (cm), mountain bikes are measured in inches (in), while hybrid bikes may use either of the two.

Therefore, finding the ideal fit means you should be checking out bike type-specific sizing charts for road, mountain, and hybrid bikes, such as the ones below!

In recent years, mountain bike manufacturers have moved away from the traditional method of sizing bikes by inches and seat tube lengths.

Nowadays, a more intuitive system using size labels such as S, M, L, and XL is in use, prompted by more radical modern frame designs and geometries.

In addition to that, most brands also provide detailed geometry charts where you can find important measurements such as stack, reach, tube angles, wheelbase, and so on.

Our mountain bike size chart below is a great starting point.

26-Inch vs. 27.5-Inch vs. 29-Inch Wheels

Modern mountain bikes typically come with 27.5-inch or 29-inch wheels, whereas 26-inch wheels are mostly reserved for fat-tire bikes.

The choice of wheel size directly influences the bike’s handling and performance—smaller wheels improve handling and maneuverability, whereas larger wheels enhance speed and obstacle rollover ability.

However, when considering the right fit for a mountain bike, the impact of wheel sizes is limited and more nuanced.

In general, wheel sizes should not be used as a way to gauge the right fit of a mountain bike, even though it can affect the riding experience by changing the geometry of the bike.

Wheel size is crucial for riding performance, but not as important for sizing adult bikes.

For shorter riders, smaller wheels can improve the feeling of maneuverability and control, improving the riding experience. Smaller wheels also lower the standover height, which has a positive effect on comfort and safety.

Conversely, taller riders may prefer larger 29-inch wheels for smoother handling and the ability to maintain momentum.

This is why many manufacturers often align wheel sizes with frame sizes—smaller frames come with 27.5-inch wheels, whereas larger frames come with 29-inch wheels.

What If You’re Between Two Sizes?

If you find that you’re between two sizes on our mountain bike frame size chart, there are a few things you should consider to be able to choose correctly.

• Riding style: Size up if you’re an aggressive rider or size down if you’re more timid in your approach.
• Stability vs. maneuverability: If you prioritize stability, size up; but if you prioritize maneuverability, size down.
• Approaching obstacles: If you prefer taking the harder line and going over obstacles rather than around them, size up. Otherwise, size down.
• Ape index: If your wingspan is longer than your height, size up; otherwise, size down.
• Experience and flexibility: If you are an experienced rider and have a flexible body, feel free to size up. Otherwise, size down to feel more confident.

Road bikes are typically sized in centimeters by measuring seat tube length. Most manufacturers also use the letter-based size labels.

However, with the introduction of modern frame geometries with sloping top tubes, it’s a good idea to also consider more advanced geometry measurements, such as stack and reach.

This approach offers a more precise fit, ensuring optimal performance and comfort on the road.

Below, our road bike size chart offers the perfect starting place to pinpoint your ideal frame size.

Note: This chart can also be used to find the right gravel and cyclocross bike size due to their similarity to road bikes.

If you’re between two sizes on our road bike size chart above, you’ll want to consider these factors before making the final choice:

• Riding for speed:  If you prefer faster and shorter rides and races (such as crits), choose a smaller frame.
• Riding for endurance: If you prefer long-distance riding, such as gran fondos or audaxes, choose a bigger frame.
• Ape index:  If your wingspan is longer than your height, choose a bigger frame. Otherwise, choose a smaller frame.
• Riding position:  If you prefer being more upright when riding, choose a smaller frame. Otherwise, choose a bigger frame for more aerodynamics.
• Weight and stiffness: If you want a bike that feels stiffer and lighter (e.g. for sprinting), choose a smaller frame.

Hybrid bikes blend the characteristics of road and mountain bikes, prioritizing comfort, practicality, and versatility.

Most manufacturers size hybrid bikes (including commuting and fitness bikes) using the letter-based approach (S, M, L, XL).

This makes it easy to find the right size, especially considering the fact these bikes are used for recreation and commuting, rather for performance.

Choose your ideal hybrid bike size from the chart below.

If you’re between two sizes on our chart above, here are a few things to consider:

• Ape index: If your wingspan is longer than your height, choose the larger frame size.
• Riding style: If you plan to ride for leisure or commuting, a larger frame might offer a more relaxed posture. For more sporty fitness riding, a smaller frame will provide better control and handling.
• Standover height: Make sure your inseam length is at least 1-2 inches longer than the standover height on the frame size you’re considering.

As we’ve already mentioned briefly above, kids’ bikes are sized by the wheel diameter. This makes choosing the right size a lot more straightforward.

Check out our kids’ bike size chart below to get a general idea of which sizes to consider for your child.

But remember, for the best fit, it’s a good idea to measure your child’s inseam and compare it to the bike’s standover height and seat height range.

Finding the right bike size using a sizing chart is pretty straightforward and a great start.

But how do you know if your bike actually fits you perfectly?

Here’s a quick checklist to help you easily determine if your bike fits you well.

• Standover height:  If the bike fits you well, there should be 1-2 inches of space between your crotch and the bike’s top tube. This is especially important on bikes with a horizontal top tube design. To check, stand over the bike with your feet flat on the ground and pull the handlebars up. If the front wheel can come up 1-2 inches, you’re good to go.
• Saddle height: With your foot on the pedal at its lowest point (6 o’clock), your leg should have only a slight bend in the knee. A good fit shouldn’t require the saddle to be at its maximum or minimum height setting for you to achieve this.
• Reach:  How does it feel holding the handlebars while sitting on the saddle and riding? If you feel the handlebars are too far away and you need to stretch to reach them, the bike is likely too big. However, if you feel cramped and constrained with a rounded back and shoulders, you should probably size up.
• Overall comfort:  Do you feel comfortable and confident while riding the bike? If the bike fits well, you should be able to handle and maneuver it with ease, especially when cornering and accelerating on the pedals.
• Knee position:  Finally, if the bike fits you well, your knee should not be hitting the handlebars when pedaling. Also, the front of your foot should not be hitting the front wheel when turning the handlebars. If this happens, you need to size up.

Why sizing varies among manufacturers?

Sizing varies among manufacturers because they take different approaches to frame design, geometry, and tube measurements and angles. Brands also target different audiences and intended uses, all of which leads to sizing variations. That's why similarly sized bikes might fit riders of different heights.

What size push bike do I need?

Push bikes are typically sold with 10" - 14" wheels. A 10-inch push bike will usually fit kids aged 18 months to 2 years; a 12-inch push bike will fit kids aged 2-4 years; while a 14" push bike will typically fit kids aged 3-5 years old. These are just general recommendations—for the best fit, consider your child's inseam length.

What size bike do I need for my height?

To find out what size bike you need for your height, you should consult a sizing chart for the type of bike you're interested in, such as road, mountain, or hybrid. Depending on the type, bike size charts will match your height to a corresponding frame size denoted in centimeters, inches, or general sizes (XS, S, M, L, XL).

Is a 26-inch bike for adults?

A 26-inch bike can be suitable both for adults and for kids, depending on the context. Kids' 26-inch bikes are suitable for teenagers and shorter adults. However, some adult bikes, such as touring bikes, fat bikes or electric bikes, also come with 26-inch wheels, but these have larger frames and are not suitable for children.

What height is a 26-inch bike good for?

A kids' 26-inch bike (a bike with 26-inch wheels) is typically suitable for teenagers and shorter adults who are around 5'0" to 5'3" tall. However, bikes for adults with 26-inch wheels, such as fat bikes or some electric bikes, are often available in a few frame sizes and might fit adults who are 6 feet in height and taller.

How do I know if a bike is too big or too small?

A bike is considered too big if you cannot stand over the frame with both feet flat on the ground without the top tube touching your crotch, or if you have to stretch too far forward to reach the handlebars. Conversely, it's considered too small if you feel cramped when riding, can't adjust the seat high enough, or your knees hit the handlebars when pedaling.

___ Inch bike for what size person?

To determine which bike size is suitable for a particular height range, consult a specialized bike size chart for the bike type you're interested in, such as our road, mountain, and hybrid size charts above. These charts match rider heights with appropriate bike sizes, allowing you to get a proper fit.
