Trek Marlin 5 Review: A Good MTB for Beginners?

CyclistsHub is supported by its readers. We may receive a commission if you buy products using our links.

In this Trek Marlin 5 review , we take a closer look at this entry-level series mountain bike.

I interviewed one of its owners and asked her a few questions you might be interested in before buying. 

You will learn, for example, whether the price matches the quality and what are its advantages and disadvantages.

KEY TAKEAWAY

The Marlin 5 is a great MTB for beginners and those who prefer a wider gear range (16 speeds) compared to the more common 1X drivetrains with 10 to 12 speeds found on modern mountain bikes. It’s perfect for cross-country or commuting but not ideal for challenging terrain because of its short 100mm fork travel.

Feel free to buy it here or continue reading for more info.

I’m a visual designer who moved to Canada in 2022. I enjoy a few hobbies, including skiing, motorcycles, and painting, but one of my favorites is cycling. 

While cycling for about 10 years, I haven’t always done so consistently. There were even some years when I didn’t ride at all. This upcoming summer will mark my second season on my Marlin 5 bike, which has a medium frame size and 29-inch wheels.

Trek Marlin 5 Summary

Trek currently offers Marlin 4 up to Marlin 8. The higher the number, the more high-end (and expensive) the bike. Below is the summary of Marlin 5, but you can also check out my Trek Marlin comparison .

Eva’s Experience with Trek Marlin 5

What other alternatives did you consider before buying the Marlin 5, and why did the Marlin 5 win out in the end?

I was choosing between the Marlin 5, Marlin 7, and Cannondale Trail 8 (Women’s) when looking for a bike. I ended up deciding based on what was available in stores at the time. I initially wanted the Marlin 7, but unfortunately, it was sold out, so I opted for the Marlin 5 instead. I must say, I was drawn to the bike’s color scheme – it looks great!

For what type of riding do you use this bike the most?

I typically ride my bike for pleasure, especially on weekends with my family. We enjoy biking in parks, on bike paths, and on easy trails. However, I’ve recently started to challenge myself by trying out more difficult trails in the forest, which is where my bike is really meant to be ridden.

How would you describe its riding characteristics?

This bike is soft and lightweight, making it easy to handle. With the right skills, it can be very maneuverable. Overall, it’s a great bike for both beginners and advanced riders.

Does the front suspension work well?

I can’t complain.

Would you like to have 1X drivetrain for simpler shifting, or are you ok with the 2X drivetrain?

In my opinion, the 2X drivetrain is fine but the correct shifting technique takes a little practice.

How comfortable is it on a scale from 1 to 10?

I would say 7-8.

What is your overall feeling from the ride?

The bike performs well on off-road terrain, as expected. However, despite having large wheels, it doesn’t quite reach the same speed on asphalt.

Is there something you don’t like about it?

The frame’s shape makes it inconvenient to place a water bottle on it. Unfortunately, a standard-sized bottle doesn’t fit, so you have to use a smaller one or place it on the side.

What do you like the most about it?

Its color! It is simply amazing (Volt to Miami Green Fade) .

Trek Marlin 5 Alternatives

The Trek Marlin 5 alternatives include bikes from the same family , such as the Marlin 4 (which is cheaper) or Marlin 6 (which is more expensive), and MTBs from other brands. I recommend checking out my article on beginner mountain bikes for more inspiration. 

Would you recommend buying Trek Marlin 5?  

It depends on who is asking. If you’re an inexperienced rider looking to get into mountain biking and off-road riding, then yes, this bike would be a great choice to start with.

Eva, thank you again for your time and for sharing your experience!

Trek Marlin FAQ

The main difference between Trek Marlin and Trek Dual-Sport is their intended use and design. Trek Marlin is an entry-level mountain bike series designed for off-road trail riding, while the Trek Dual-Sport is a versatile hybrid bike capable of handling a wider range of terrain, including pavement, gravel roads, and light off-road trails.

The main differences between Trek Marlin 4 and Marlin 5 are in the groupset and weight. Marlin 4 uses 3×7spd while the Marlin 5 has a 2×8spd drivetrain. The 3X drivetrains are becoming obsolete because of their complexity and high demands on correct shifting. That’s why I recommend spending more on Marlin 5.

The main differences between Trek Marlin 5 and Marlin 6 are in the groupset and weight. Marlin 5 uses 2×8spd while the Marlin 6 has a 1×10spd drivetrain. The 1X drivetrains are popular due to their simplicity, ease of use, and lower weight. I believe the Marlin 6 is worth paying more. Despite the narrower gear range, its use is much easier for beginners. 

Trek Marlin 5 is an entry-level mountain bike for recreational riders and commuters. It is generally considered a good value for the price, offering a solid set of features for an entry-level bike. To learn more about it, read this entire article.

Trek Marlin 5 Gen 2

Marlin 5 is a trail-worthy daily rider that's perfectly suited for everyday adventures, on and off the trail. A suspension fork, 2x8 drivetrain, and mounts for a rack and kickstand make it an ideal choice for new trail riders or anyone looking for a comfortable, stable commuter with the ruggedness of a real mountain bike. It's right for you if... You're new to the trail, and you're looking for a real mountain bike that doubles as a commuter—and you want it all at an exceptional value. The tech you get A lightweight aluminum frame with internal routing to protect your cables and add to the bike's sleek look, 2x8 drivetrain, a wide range of gearing so you always have the right gear for your terrain, powerful hydraulic disc brakes, and a terrain-smoothing suspension fork with a lockout. The final word Marlin 5 is a great ride for all your adventures. But it's also versatile, and Marlin 5 is a popular ride on college campuses, because the rack and kickstand mounts make it easy to accessorize and haul a load. Why you'll love it - It's a real mountain bike that's also perfectly suited to daily commutes, rides around campus, or just getting from A to B on any surface - Smaller frame sizes (XXS, XS, and S) have short-reach brake levers that make it easier and more comfortable for riders with smaller hands to brake confidently - Marlin models in XXS through S frame sizes have a curved top tube and a lower standover height that makes it easier for smaller riders to mount and dismount - Rack and kickstand mounts make it easy to accessorize, so your mountain bike can double as a rugged commuter - Like every model in the Marlin family, it's backed by Trek's lifetime warranty Wheel size: - Size XX-Small: 26-inch - Sizes X-Small – Small: 27.5-inch - Sizes Medium – XX-Large: 29-inch

Will my bike have a curved top tube?

Smaller frames (XXS-S) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. The larger frames (M and up) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.

Trek Marlin 5 Review

Trek Marlin 5 is an entry-level bike from Treks’ Mountain Bikes series. It offers a lot of features you’d expect from an expensive bike like internal cable shifting and hydraulic brakes. Some of the recent updates to the model leading up to Trek Marin 5 2020 made it the best in the budget category and very easy to recommend to any trail riding beginner.

Trek Marlin 5 is one of the best entry-level mountain bikes and it’s perfect for you if you are

• trying to get into Mountain Biking or trailing and not sure if you’d like the sport. In this case, Marlin 5 makes for a great beginner-friendly bike which you can use to test and level up your training skills before upgrading to something more advanced. The Drivetrain of this bike provides you with a huge combination of speeds which can come handy.
• looking for a commuting bike for school, and your path involves a few rough roads or would enjoy a bit of trailing on the side as a hobby. If your commuting path involves some roads which need repair, Marlin 5 might be the perfect bike because unlike a hybrid at this price range you will be getting a good suspension with 100mm travel and a preload adjustment for switching between smoother rides and a bit rougher ones.
• trying to get the best of both worlds bike and not ready to spend big bucks on the more expensive bikes then Trek Marlin 5 is a match made in heaven. With the price range of 500-600 dollars, you will be getting a solid experience without breaking the bank.

This is our Trek Marlin 5 Review which provides a detailed overview of the bike with a comprehensive review of all the components and parts. There is also a specs list sorted down below for ease of access.

Trek Marlin 5 Specs

Trek Marlin 5 comes with a light-weight Trek Silver Alpha aluminium frame which offers sturdiness for your trails while still being light enough to not wear you down during long rides.

You can expect some pretty good welding with internal cable shift and brake hose routing which you see on more expensive bikes and it protects your cables from getting damaged from varying weather and landscapes.

This becomes all the more relevant in the mountain trail picture where the terrain does not side with the best of the conditions. The frame manages to hide all the cables inside the frame which also makes for a stunning look.

Going with the theme of Trek Marlin 5 making the best of both worlds when coming to Mountain Biking and Commuting, It has good rack mounts if you want to load your bike for longer trails.

We got a wide Bontrager alloy, 31.8mm with Blendr compatibility which enables you to mount accessories like lights, mobile phone dock, or a GoPro for your next adventure.

We got a matching Bontrager alloy with a 5mm rise and oversize clamping diameter which increases control and stability during the shakiest of rides.

Bontrager XR Endurance Comp on this bike provides a good grip for better handling and control. Although its non-traditional shape can feel a bit weird, they make for a good resting place for your palms, which you will appreciate on longer journeys.

Saddles in Marlin 5 are pretty straightforward, they use two variants of Bontrager Arvada depending on male/female versions.

Sizes and Variants

This particular model is very popular with beginning Mountain Bikers because it has a wide range of sizes to choose from which ensures that you are always on the best possible fit for you. 7 sizes are ranging from XS all the up to 2XL and come in two variants in frames depending on the version.

The Female version is almost the same as the Unisex version of the bike only changes being a different saddle variant and If you choose a Female XS or S size then you’ll be getting a curved upper tube for some extra standover.

There aren’t many good trail bikes for Women in this price range but Trek Marlin 5 is a good choice considering the women-specific saddle and frames.

A detailed overview of sizes and measurements for finding the best fit for you is provided in the table below.

Trek Marlin 5 Size Chart

Wheels and Rims

When it comes to wheels, Marlin 5 has smart wheels size which means that you are going to roll with the largest wheels size possible depending upon the size. The wheels come in the two most popular sizes, 27.5” for XS and S and 29” for everything from M to 2XL.

So an L or M is a Trek Marlin 5 29er while an XS or S is a Trek Marlin 5 27.5er

Both wheel sizes are big enough to provide a smooth riding experience on an MTB and also offer a low center of gravity for a sturdier control.

The Merlin 5 rolls on a Bontrager XR2, 29×2.20˝ in the front, and 29×2.0˝ on the rear but you should know, however, that these wheels are not tubeless but I don’t think that’s a deal-breaker because we are focusing on getting the essentials right at this price point. Having said that, a quick-release front wheel is a plus for quickly swapping your front in case of any damage.

Forks and Suspension

Coming to the Forks, Marlin 5 runs an SR Suntour XCE 28 which is a 28mm stanchion fork with 100mm travel which falls into the recommended range of 80-120mm by most mountain bikers. The suspension also comes with a preload, which can be used to adjust the shock and spring of the bike to an optimum range of operation. When it is raised, the bike will be on top of its travel and the converse closer to the bottom of its suspension travel.

Marlin 5 comes with Tektro HD-275 hydraulic disc brakes as opposed to Marlin 4’s Mechanical disc brakes which offers a more responsive and reliable experience in all types of weather conditions.

Hydraulic brakes are more relevant when it comes to Mountain Biking because you often need to make quick turns and pace changes. Using traditional mechanical caliper brakes can not only wear your brake pads quickly but also become unreliable during damp weather conditions. You can completely count on disc brakes on this situation because it is proven to be more weather resistant and pairing it up with hydraulics will ensure that you don’t have to pull the brakes as hard.

Most people coming from bikes using non-hydraulics quickly appreciate how game-changing hydraulic brakes are.

Trek also paid close attention to smaller sizes and equipped XS and S sizes with short reach levers to make it easy for bikers with smaller hands.

Most of the components on this bike are from Shimano which are known to be very reliable in the Mountain Biking space and rightfully so. The drivetrain consists of shifters, derailleurs, chain, cassette, and crankset.

Trek Marlin 5 is set up with a Shimano HG200, 12-32, 7-speed cassette in the rear, and a Shimano Tourney TY301, 42/34/24 in the front. They both operate with the Shimano Tourney TY300 front and back derailleurs which offer a great variety of speeds and good shifting for both country trailing and rugged commuting.

One big pro with the Tourney setup is that they all work together perfectly with no off-brand components and there is no chance to cause any compatibility issues.

Marlin 5’s got Shimano Altus M310, 3X7 speed shifters which is a trigger shifters set up which you can easily operate with your thumb and index fingers quickly during your trial.

Trek Marlin 5 weight

So, How much does a Marlin 5 weigh? The Medium size comes in about 14.59 kg or 32.17 lbs when tubes and other components are attached.

This model has a combined weight limit of 136 kg or around 300lbs, this includes the weight of the biker, the bike and the cargo carried.

Trek Marlin 5 Price

Are trek bikes worth the money? let me tell you price is one of the main advantages for Marlin 5 because there are very few bikes that have a budget-friendly price tag while still maintaining that middle-ground between quality and price. This makes a huge difference because when a bike manufacturer wants to get the price down it is often reflected in the quality of the bike’s components.

You might have experienced this first hand if you used one of those target/Walmart bikes which try to sell people bikes with poor quality while still maintaining their profit margins. But unlike those other bike manufacturers, Trek found the perfect middle ground for a budget-friendly mountain bike which gets all the essentials right.

Looking at the specs sheet makes it quite apparent that Trek didn’t make many compromises with the quality as they use reliable components made by Shimano and Bontrager and not some off-brand company.

Like every other Marlin bicycle, Marlin 5 also comes with a lifetime warranty which is rare to see at this price range and always a sweet thing to have.

Trek Marlin 5 upgrades and accessories

As I previously mentioned above this is a great bike to get into trail riding and off-roading or just to see if you like the experience of Mountain biking before investing too heavily into it. But if you seem to enjoy and want to take the whole thing up a notch, upgrading some components will be in your best interests.

Marlin 5 is a great bike for normal to intermediate trail paths but if you are past those trails and want to enjoy more technical routes like mountain trails etc then investing in these components can make a great difference.

Trek Marlin 5 fork upgrade is one of the most recommended upgrades if you wish to improve your stability on a rocky/hilly path. This bike uses what’s called a G2 Geometry which means you can easily find and replace parts that fit your needs. If you have some good number of miles under your belt, I also recommend upgrading your grips and pedals but I would stop there.

While this is a good starter bike, I would suggest you switch to a better model specifically suiting your needs if you are willing to invest more in upgrading the components because investing in upgrading a starter bike has diminishing returns as you upgrade more and more as you have to worry about the core parts like frames and stem in the future.

With that being said these are some good upgrades you might want to consider for a more smooth riding experience.

There are some great accessories for Merlin 5 on the market because of its Blendr integration capability. After choosing a good mount for Blendr integration, I recommend this, your bike is ready for these cool accessories

I for sure think that some portion of Trek Marlin’s popularity comes from its design aesthetics and cool graphics. The design of the bike is easily on par with the more expensive bikes. And the colors of this model are very well chosen and suit all terrains and settings perfectly.

Trek Marlin 5 comes in three color options

• Matte Trek Black

Many fans anticipated an improved Trek Marlin 5 Red version (like the one in the past) which would have been very cool to see on the road but in my opinion all three look stunning.

We hope that you find this Trek Marlin 5 review useful, to clear a bit more on the topics there is a FAQ’s section below where we have included most frequently asked questions by customers.

According to Trek Bike Archives, Trek started making Marlin 5’s from 2015.

Trek Marlin 5 ranges around 500-600$ price range which makes for a budget-friendly bike for trail riding as well as commuting. Check the price here.

Front tires are mounted on Trek Marlin 5 using a quick-release front wheel, which enables you to swap out the damaged wheel and mount a new one with relative ease.

This depends on many factors like your height and inseam measurements. Find a comprehensive specific measurement table here.

Trek Marlin has disc brakes which means you should not oil them. Oiling aside even touching the rotors with your bare hands might contaminate the rotors with your body oils and decrease the braking capacity.

Oiling disc brakes are considered the number one cardinal sin so make sure to avoid it all costs. If by any means oil made its way to the rotors use alcohol or de-greaser with a kitchen paper or dry clean cloth to remove it.

It comes with a Bontrager alloy, 31.8mm, 7-degree stem which is Blendr compatible enabling you to mount different accessories.

The frame and most of the other skeleton are made of light-weight Trek Silver Alpha Aluminium which offers very good manoeuvrability and sturdiness still being pretty light.

With rack mounts available on the back of the Marlin 5, you can easily mount a child seat. One good suggestion would be this.

Review of Trek Marlin 5 Gen 2

Trek Marlin 5 Gen 2 is an entry-level trail bike ideally suited for beginners and recreational riders who need a dependable hardtail to hit the trails or use for a daily commute.

It features Shimano Altus 2×8 components, hydraulic disc brakes, an 80-100mm travel fork, and comes in four stunning paint jobs. 

The Marlin 5 has been one of the best-selling mountain bikes in this price range for a good reason, and we expect the Gen 2 version to follow in its steps.

• Hydraulic disc brakes
• 100 mm of front travel
• Progressive wheel sizing
• Heavy coil fork

Trek Marlin 5 Gen 2 Full List of Specs

Trek marlin 5 gen 2 full review.

If you’re considering buying your first mountain bike or treating yourself to a brand-new bicycle you’ll use as an everyday workhorse and commuter; the Marlin 5 Gen 2 is a solid choice.

The Trek Marlin 5 is an entry-level trail bike that has a lot to offer to trail lovers. If you want to figure out whether this bike is right for you, check out our detailed review below!

Quality Frame and Fork

The base of the Trek Marlin 5 Gen 2 is the brand’s Alpha Silver aluminum frame with a sleek design and stable geometry, suitable for various rider needs. This frame features internal cable routing that protects your cables from the elements and adds to the bike’s clean look.

Marlin 5’s frame is available in eight sizes , so you’re guaranteed to find the perfect one for your height. The SR Suntour fork is basic but provides 100 mm (or 80mm on the XS) of travel to take the sting off light trails. This fork has a coil spring which makes it a bit heavy, but it comes with a preload function, which is a nice plus.

Precise Hydraulic Disc Brakes

The star of the show on the Trek Marlin 5 Gen 2 is its Tektro hydraulic disc brakes . We are always pleasantly surprised to see them on bikes below $1,000, as hydraulic discs are a rare find in this price range.

Thanks to these hydraulic disc brakes, the Trek Marlin 5 Gen 2 is a bike that performs well in all weather conditions.

Compared to all other types, hydraulic brakes output the most power and provide the most precision. Trek has even gone so far as to install short-reach levers on the smallest frames.

2.20″ Tires and Progressive Wheel Sizing

Depending on how tall you are and which frame size end up going for, your Trek Marlin 5 will come with either 26″, 27.5″, or 29″ wheels .

The XXS frame has 26″ wheels, the XS and S frames come with 27.5″ wheels, and all other sizes are 29ers. Progressive wheel sizing and a curved top tube on the smaller frames decrease the standover height of the bike and ensure a much better fit for all rider heights.

The rims on all sizes are Bontrager Connection. They’re double-walled and have 32 spokes, which means they’ll take plenty of abuse. The Bontrager XR2 2.2″ tires are not tubeless, but they will give you plenty of grip on the three different wheel diameters. The 27.5″ wheels have extra clearance for 2.4″ tires. 

Shimano Drivetrain

Another positive aspect of the Trek Marlin 5 Gen 2 is that the entire drivetrain comprises Shimano parts. Sure, they are entry-level quality, but they offer more than enough performance and precision for the average beginner trail rider.

The Marlin 5 Gen 2 has 16 gears on a 2×8-speed drivetrain and comes with a complete Shimano Altus M315 drivetrain , which is one quality class higher than Tourney. This compares to the previous model’s more complex and heavier 3×7-speed drivetrain. 

The crankset is 36/22t with 160mm cranks on the XXS and 170mm on the other sizes. This crankset pairs with a 12-32t cassette. 

Dependable Bontrager Parts

Bontrager is Trek’s in-house brand that makes numerous parts and accessories. The Bontrager label on Trek Marlin 5 Gen 2 can be seen on the saddle, seat post, handlebar, grips, and stem.

Trek makes all of these parts specifically for their bikes, which means they are 100% compatible and perform for a long time without any issues. However, one of this bike’s downsides is that the headset is not tapered , so you might have a harder time upgrading the fork if you ever decide to do that.

Trek Marlin 5 Gen 2 Sizing Chart

• XXS — 4’5″ – 4’9″ / 135 – 145 cm
• XS — 4’9″ – 5’1″ / 145 – 155 cm
• S —  5’1″ – 5’5″ / 155 – 165 cm
• M —  5’5″ – 5’8″ / 165 – 173 cm
• M/L — 5’8″ – 5’11” / 173 – 180 cm
• L —  5’11” – 6’2″ / 180 – 188 cm
• XL —  6’2″ – 6’5″ / 188 – 195 cm
• 2XL — 6’5″ – 6’8″ / 195 – 203 cm

Who Is Trek Marlin 5 Gen 2 Best Suited For?

Like any other bicycle, the Trek Marlin 5 will not be a good buy for everyone. It is an entry-level machine mainly intended for beginner riders and those who do not take cycling too seriously.

Trek Marlin 5 Gen 2 should be shortlisted by beginner riders who are looking for their first mountain bike to commute or explore the dirt roads in their area.

If riding a bike is a weekend activity or a mode of transportation for you, then Marlin 5 will meet and exceed your expectations. You’ll be able to cover thousands of miles on it without any upgrades and explore farther than before.

However, if your idea of cycling is to hit trails as hard as possible and test your skills and limits, then you should save a bit more money and invest in a bike with slightly better components.

Is Marlin 5 Gen 2 a Good Buy?

The value for money you get out of this bike leads us to conclude that the Trek Marlin 5 Gen 2 is an excellent buy . For around $700, you get a high-grade aluminum frame that’s light, rigid, and durable (it’s even found on some  more expensive Trek bikes).

The drivetrain is entry-level, but the brakes are powered by hydraulics which is the best setup you can get right now.

For this amount of money, it’s a bargain. Therefore, if you’re the type of rider we’ve described, the Marlin 5 Gen 2 is a purchase that will put a long-lasting smile on your face if you go forward with it.

Thank you BIKEXCHANGE for helping me to make up my mind in purchasing the Marlin 5!

You’re welcome, Gwen! We’re happy we could help! Have fun with your new bike!

Great review. One question .. is this the old 5 or new 5 model? The new Marlin 5 design as I understand it being the old 5 plus aspects of Marlin 6 bike & otherwise that’s led to discontinuance of the Marlin 6 and only selling a Marlin 5 & 7 model going forward?

Much appreciated!

I am still riding my 2017 Marlin 6 its been too Hell and back. I live in the woods near Downtown Nashville 32 Thousand miles all pavement. riding in Hurricanes and Polor Vortex. Just got new breaks and Maxxis Hook Worm tires.I do circules around Gravel bikes.

Thinking about buying one of these and as an entry level rider seems like the best choice.

thanks for the review! it has made my mind up

The trek marlin 5 is a great bike. Bought for my wife, i sneak in rides. It isnt too heavy, the bigger 29″ tires are fun to feel a little bit higher off the ground. The braking system is fantastic and was a selling point for me.

Trek Marlin 5 Review: The Best Entry-Level Mountain Bike Around

I reviewed the entry-level Trek Marlin 5 bike and compared it to similar bikes - how did it fair?

As an experienced rider, I know what it takes to make a good bike, whether that's a top-of-the-range road bike or an entry-level mountain bike .

Overall I found the Trek Marlin 5 to have plenty of positives, including hydraulic disc brakes and Shimano derailleurs - honestly, it doesn't stop there!

For a more in-depth look, continue reading my Trek Marlin 5 review!

Table of Contents

Full Specification

Key features, alpha silver aluminum frame.

Trek Marlin 5 comes with an impressive alloy frame and things are kept tidy with the cables being internally routed.

For an entry-level bike, this is most surprising (but also welcomed!). It is rare to see internally routed cables. I love it, it makes the bike look sleek and it stops the cables from collecting dirt and becoming damaged.

SR Suntour XCE 28 Suspension Fork

It comes with 100mm of travel suspension so when faced with rougher terrain, it excels. There isn't a moment when things feel too demanding for the Marlin 5 thanks to the SR Suntour XCE 28.

Bontrager Arvada Saddle

Trek appears to like to kit their bikes out with Bontrager components and you won't hear me complaining! This saddle is there to give you comfort on long days riding and it works well for the commuter too!

Shimano Tourney 21 Speed Drivetrain  

It's common to see Shimano Tourney components at this price point. The quality is good and you have options!

You can either choose between a 3 x front derailleur or if you wish to reduce weight, you can opt for a 1 x Shimano Tourney at the front.

Which one should you choose?

Choosing the 3x will give you greater flexibility but more to think about. The 1x system will reduce the number of gears but allows you to spend more time focusing on your riding.

I favor 1x systems for their simplicity. When you're mountain biking, needing to changing the big ring can be one thing too many to get used to, especially if this is your entry-level bike and therefore your first!

If you're looking where the bike could be upgraded in the future then it could be the Shimano Tourney TY300 parts. Whilst they are decent and they are certainly a fantastic starting point, there are better options out there. A small upgrade in the future could see you finding it easier to climb hills.

Tektro HD-275 Hydraulic Disc Brakes

Hydraulic disc brakes on an entry-level bike? Trek has nailed it.

For beginner riders out there, hydraulic disc brakes are (for many, not all), the best type of braking system there is.

A slight touch on the brake levers is all you need to get a response...you don't get that from mechanical discs or rim brakes.

I came to fully appreciate hydraulic disc brakes going down Coll de sa Batalla for the first time, where I gripped on like my life depended on (it felt it did).

Since then. No turning back for me, there's only one form of brake system for me!

Bontrager XR2 27.5/29 x 2.2/2.0” Tires

Another Bontrager component!

These tires are of brilliant quality and they excel on mountain roads as well as gravel.

A downside to them is that they don't perform as well when things get muddy.

Wheel Sizes

There are different wheel sizes depending on the bike size you get.

The XS frame comes with 27.5" wheels.

Whereas, anything above that frame size gets 29" wheels.

At 5'4 in height, a lot of manufacturers would like to see me on 27.5" wheels, however, I ride 29ers on my MTB. I find this to be more comfortable and I don't feel hindered by having larger wheels.

What I'm saying is, test some bikes out, get a feel for what you like. Rules are there to be broken!

As I briefly touched upon earlier, the Marlin 5 comes with an alpha silver aluminum frame.

An alloy frame is a popular choice within this price bracket as it doesn't add extra weight to the bike as a steel frame would but it provides a good level of durability for a mountain bike.

Whilst you do get a good amount of durability, you have to factor in that this is a bike on a budget and it can't take on everything. It isn't designed for jumping so this is something to keep in mind if you're wanting a bike for serious trails.

All of the cables are internally stored in the bike, helping it to have a cleaner, more stylish look as well as improve the durability of the cables. 

The bike is available in three attractive colors, including black, green, and teal. These shades are uniquely beautiful and well-selected, so every cyclist will find the right color for them.

You can add a rear rack and kickstand to the Marlin 5’s frame, which makes this model a great choice for commuters, as well as adventurous cyclists. 

Do keep in mind that if this mountain bike was made of carbon fiber, it wouldn’t weigh the frame down as much, but the Trek Marlin 5 would come in at a much higher price point.

On Which Terrain Does The Trek Marlin 5 Perform Well?

We have to keep in mind that the Trek Marlin 5 is an entry-level machine so it isn't designed to be ridden by an expert rider, taking it on challenging trail riding.

Saying that the Marlin 5 is capable of rougher terrain and it works well as a trail bike. I'd always suggest that you check what the difficulty levels are before you hit the trail.

Bontrager Components

Let's clear something up for beginner riders getting into mountain biking.

Trek fits their bikes with 'Bontrager' parts. This is a Trek brand and made in-house.

For some brands, this isn't a sign of quality, yet this isn't the case here. Bontrager is a sign of quality.

On the Trek Marlin 5, Bontrager features a lot; the seat, seat post, handlebars, grips, and stem.

The stem is Bontrager alloy,  31. 8mm 7-degree Blendr compatible .

One of the best things about using these parts is that they are truly compatible across the Trek range of bikes.

As they are made by Trek, for Trek, the parts are made with the precise specification of their bikes so everything will fit seamlessly together!

For beginner riders, this is perfect as you won't need to give much thought about whether you're buying the correct parts.

[Check out this video from Trek for an overview of the range.]

Alternatives To The Trek Marlin 5

Without a doubt the Marlin 5 is feature-rich but how does this entry-level mountain bike compare to other bikes?

Trek Marlin 5 Vs Marlin 6

The first difference has to be the cost, the Trek Marlin 5 comes is quite a lot less than the 6 - this makes it an ideal first trail bike for those new to mountain biking, or those on a budget.

Having said that for trail riders looking to spend a bit more money, you do get a durable fork, a 2x drivetrain - including a better groupset and you even get a lighter bike!

One thing I do like with the Trek Marlin 6 is that there is the option to have either a man's frame or a women's. Whilst I find that women can ride men's bikes, it's nice to have an angled top tube.

You also get more options to customize certain features, so if you fancy a different wheel size, then the Marlin 6 can cater to that.

The standout benefit would be the upgrades with the fork - the fork on the 6 is a fair bit lighter than that on the Marlin 5. This reduces the weight of the bike, making biking trails or the commute easier.

Equally, the fork has a lockout and preload function so you are able to completely lock the fork to increase how efficiently you pedal - making your adventures easier!

Trek Marlin 5 Vs Giant Talon 3

The Giant Talon 3 has some good reviews and they're well deserved. In a lot of ways, these entry-level bikes are similar so are there any features that set them apart?

When compared to the Marlin 5, the Talon 3 seems to offer more traction when pedaling. This could potentially mean that as a rider, you don't feel as safe underfoot on the Trek Marlin and you could find that you're more likely to slip.

Though, the Trek Marlin 5 does give you a greater range of color types to choose from. So for trail riders who want to make their bike their own, the Trek could be the way to go.

There is a difference in wheel size too, with the Trek Marlin 5 you get 29" wheels, whereas Giant Talon 3 gets 27.5". Which one is better will come down to what you want from a bike.

The 27.5" wheels do mean the bike is lighter, which could be an appealing bicycle option to the commuter, beginners, or anyone who wants a bit more control!

Both hardtail mountain bikes have plenty to offer and the specifications are similar. For me, it all comes down to wheel sizes and the experience you want when you're cycling.

Trek Marlin 5 FAQs

Can i do tabletop jumps on the trek marlin 5.

The Marlin 5 is part of Treks' entry-level range and is not suitable to be taken on any type of jumps.

The wheels and tires are not designed to cope with jumps and could bend, even on a small jump so don't try it!

Can I Use Tubeless Tires On The Trek Marlin 5 bike?

Unfortunately not. The wheels aren't compatible with tubeless tires.

However, the wheels and tires are robust and suit mountain bikes well.

Does the Trek Marlin 5 have lockout suspension?

The Marlin 5 doesn't have a full lockout suspension. You do get a coil spring that has a pre-load adjuster though.

[Here are some ideas for when you really want to push yourself! 😉 ]

Final Thoughts

If you're wanting performance on a budget, there are plenty of plus points from this 29er.

The aluminium frame and Shimano Tourney components give the Trek Marlin 5 something to shout about.

Let's not forget the hydraulic disc brakes, making them ideal for dirt roads or a commute in any weather conditions. Braking at all speeds shouldn't be an issue with disc brakes.

Overall I have positive things to say about this bicycle. All terrains, mountains, trails, or commutes, the Trek Marlin 5 can do them all!

Ghost Bikes Review...The Ghost To Be Admired, Not Feared

Trek Marlin 5 ( 2022 ) Review – The Verdict!

Trek Marlin 5 is a fantastic mountain bike for the trails. The new 2022 model is an even better trail-worthy daily rider for most people looking for an affordable option by an excellent bike brand .

This bike comes with everything you might need in a trail bike – a 2×8 drivetrain, a good suspension fork, many mounts for racks and a kickstand, and mechanical disc brakes.

The last model ( 2021 ) of Marlin 5 has been featured ( “ Great Value and Performance ” award ) as one of the most incredible budget mountain bikes of the year. Read the full article here .

Trek Marlin 5 ( 2022 ) in a glance:

The Frame & Suspension Fork

Trek Marlin 5 features a high-quality Trek Alpha Silver Aluminum frame from the last model, Trek Marlin 6 ( 2021 ), but in a different color scheme. The frame looks and feels great with the internal cable routing, which means all your shift and brake cables go inside the frame for a clean and simple look.

You also get a rear kickstand mount (sold separately ) and rack mounts if you plan to use the Marlin 5 for long rides.

The front fork is the same as Trek Marlin 6 from 2021 and is the most significant upgrade from the Marlin 5 of 2021 – SR Suntour XCT 30 . It offers a hydraulic lockout to have a fully rigid fork or a full suspension fork. This is a great option for anyone who wants to ride Marlin 5 on extended road sections where efficiency should be much better with a rigid fork.

Drivetrain and Other Components

Everything here also matches the Marlin 6 ( 2021 ), which means many exceptional components on top of the aluminum frame. Let’s start with the most important one – the drivetrain.

Trek Marlin 5 is now set up with a 2 x 8 drivetrain, with just 2 rings in the front ( the previous model had 3 ) and 8 speeds at the back ( the previous model had 7 ). As you might expect from a Trek bike, the entire groupset is Shimano Altus – a second-tier groupset in the Shimano hierarchy. We love Altus for its affordability and the amazing shifting it offers.

As a result of this change from the last model, you get a similar range just now with 2 rings up front, which means you will need to do quite a bit less shifting.

The shifting itself is commanded by simple Shimano Altus trigger shifters. They are simple to operate and very reliable in the long run.

Trek Marlin 5 Brakes

Similarly priced mountain bikes often come with simple mechanical disc brakes, but we have a much better braking system here.

To bring the bike to a slow, you’ve got some Tektro hydraulic disc brakes – these are going to be mineral oil brakes which means they’re going to perform amazingly in all types of conditions. They use a two-piston caliper on 160mm rotors in the front and the rear.

Smart Wheel Size

Trek is a brand that is well known for the vast variety of sizes that are available for most of their mid-priced and high-end bikes. But now, you can find the best bike size for you, even for entry-level models like the Marlin 5.

Trek Marlin 5 comes with the so-called smart wheel size. This means you get a different wheel size on the various frame sizes. The bike can roll on 26”, 27.5”, or 29” wheels.

Here’s a simple table with the sizing:

Trek Marlin 5 ( 2022 ) – The Verdict!

Should you buy it, shortlist it or avoid it? Here’s our conclusion. We think that you should buy the Trek Marlin 5 ( 2022 ) . If you can spend around $700 for an entry-level mountain bike for the trails, then this bike should be on the top of your list. If your budget is less than that, but you still want a decent mountain bike, check the Cannondale Trail 8 ( 2021 ) .

Review Of Trek Marlin 5: Budget-Friendly MTB for Beginners

T rek Marlin 5 is a phenomenal, trail-ready 29er that costs little and gets the job done on different types of surfaces, including paved and unpaved roads.

Beginner riders are often faced with a tough dilemma — purchase a versatile and comfortable city bike to commute or a real MTB to have fun and embark on off-road adventures.

With Trek Marlin 5 Gen 2 , you can do both. This 29er has the ruggedness of a true trail-blazer but has the ability to double as an everyday workhorse to take on short urban commutes.

One of Marlin 5’s biggest advantages is the low price. This bike costs just $720 , which puts it in the budget category. Still, there’s a lot to be excited about even with such an attractive price.

Trek Marlin 5 Quick Overview

Marlin 5 main features, is trek marlin 5 the right choice for you, verdict: worth the money (or not), trek marlin 5 (2022).

Marlin 5 is characterized by an excellent off-road-ready aluminum frame, cushy front suspension, burly wheels and tires, hydraulic disc brakes and a lot more.

It’s one of the best-valued models from the Marlin series, offering multiple improvements compared to the lower-priced Marlin 4. Some of these are better brakes, better hubs, and a better bottom bracket.

It’s an entry-level bicycle, most suitable for beginner riders who plan to do a little bit of everything and too much of nothing.

• Frame : Alpha Silver Aluminum
• Fork: SR Suntour XCT 30, 100 mm
• Front Derailleur: Shimano Altus M315
• Rear Derailleur: Shimano Altus M310
• Brakes: Tektro hydraulic disc, 160/160mm rotors
• Rims: Bontrager Connection, double-wall
• Tire Size: 27.5″ / 29″ x 2.20″
• Weight: 13.97 kg / 30.81 lbs

See All Specs on Marlin 5 Product Page

If you have a budget of $740 to spend on your next trail bike, Marlin 5 is pretty much the most you can get in this category.

Trek is known for bikes that have good value to money, so this Marlin series model has some worthy components and does not make too many compromises.

Lightweight Alpha Silver Aluminum Frame

Trek Marlin 5 has the same Alpha Silver Aluminum frame seen on all bikes from this lineup. It is characterized by a versatile head tube angle of 69.5 degrees. That’s a good compromise between steep and slack geometry. That means this bike will perform well in most conditions, including climbing, descending, and cornering.

Light, durable, and comfortable Alpha Silver Aluminum frame is Marlin 5’s biggest selling point, seen on other more expensive bikes from Trek’s MTB lineup.

All cables are internally routed which makes them last longer and improves the overall appearance of the bike. Riders can add a rear rack and a rear kickstand, which would make Marlin 5 ready for daily commutes as well.

You can get Marlin 5 in four modern and attractive colors: Lithium Grey, Radioactive Red, Volt to Miami green fade, and Azure. They’re beautiful!

Springy SR Suntour Fork

Marlin 5 is equipped with a low-ranked SR Suntour XCT 30 fork with a coil spring. This fork is quite heavy but beginner riders without too much off-road experience will like it because it provides plenty of comfort.

When it comes to adjustability, just the preload function is available, so you can dial the fork to your liking and ensure a more comfortable ride and better responsiveness.

It’s important to note that the XS frame size comes with 80 mm of travel, whereas all other frame sizes have 100 mm of travel in the fork.

Best Feature: Hydraulic Disc Brakes

The feature that will make all Marlin 5 owners happy is the hydraulic disc brakes . This is the biggest improvement compared to the cheaper Marlin 4 which comes with mechanical disc brakes.

Hydraulic disc brakes present a major increase in stopping power and precision . They require less strength input from your fingers but offer more braking power output.

Trek has gone a step further and equipped the smaller frame sizes with short-reach brake levers to accommodate short riders with smaller hands.

Delicate Shimano Derailleurs

The main points of improvement on Trek Marlin 5 are its derailleurs. Compared to the previous releases, Marlin 5 has Shimano Altus components

Depending on how you take care of them, they might last you for years and miles to come. However, if you’re not careful and you shift under tension or you fall off your bike and smash them, they might give you some headaches.

Still, that’s not something an average rider planning to take Marlin 5 out on weekend adventures and weekday commutes should worry about. Plus, updating to higher-value Altus, Acera, or Alivio groupsets is not a big investment.

Beefy Bontrager Wheels and Tires

Last but not least, the beefy Bontrager wheels and tires are some of the first things you will notice on your Marlin 5. The 13.5″ and 15.5″ sized frames come with 27.5″ wheels, whereas all larger frames come with 29″ wheels.

The wheels are Bontrager Connection. They have 32 spokes, so they are quite strong, and they’re double-walled which means they can withstand some beating.

The Bontrager XR2 tires are 2.20″ wide on 27.5″ wheels. However, when it comes to 29″ wheels, the rear is narrower at 2.0″.

These wheels and tires are a bit heavier than ideal , but once you get them going, they’ll take you wherever you direct the handlebars.

Geometry & Sizing Table

We especially like it because it’s good at more than one thing.

Trek Marlin 5 is not strictly a trail-specific bike that would feel sluggish in all other settings. It’s equally efficient on both paved roads and dirt roads.

However, its wide tires, massive wheels, and capable hydraulic disc brakes still make it more suitable for riders who plan to spend more time in forests and on mountains than on smooth city streets.

Other Marlin Models

• Marlin 4 – MSRP $630 – Has a lightweight aluminum frame, 21 gears, 100 mm of front suspension, and strong mechanical disc brakes.
• Marlin 5 – MSRP $740 – Combines a light aluminum frame, plush SR Suntour suspension, entry-level Shimano drivetrain, and powerful hydraulic disc brakes in a good-looking trail package. Men and women-specific models available.
• Marlin 6 – MSRP $850 – This model is built with an Alpha Silver Aluminum frame, a 1×10 mid-range Shimano drivetrain, burly tires, and comes with 100 mm of front suspension travel with lockout. It’s available in men’s and women’s versions.
• Marlin 7 – MSRP $1,030 – Trek’s race-worthy model with an Alloy frame, superior RockShox front suspension, quality 1×10 drivetrain, Shimano components, and improved Shimano hydraulic disc brakes.

To the right buyer, Trek Marlin 5 is definitely worth the money . This is a lot of bike for just $740, specifically when it comes to the components. The hydraulic disc brakes increase the value of the bike, as well as the high-quality aluminum frame.

However, if you value every cent and you don’t intend to tackle steep hills or ride in wet weather, you can save and get Trek Marlin 4 with mechanical disc brakes and slightly lower-ranked hubs and bottom bracket.

My wife and I just bought 2 29 inch Lithium Gray Marlin 5 Gen 2 bikes. So far so good other than a flat tire I experienced but that’s not Treks fault by any means. We like the weight and the smooth ride it has.

Trek 5 is my 1st Mountain Bike I have been riding it 3x a week Doing some hard bush trails. It really seems to handle all trails well. No one knows that my bike isnt really expensive . They all say “love your bike ” I just love my bike but will upgrade to a better Trek when I have obtained more skills. Thanks Natalie

Hi Natalie, Well as they say, a Trek is a Trek. The brand itself speaks for itself. It also depends on the kind of ride you do.

lol “my son doesn’t abuse his bike he just broke all of the most easily abused parts of it”

Hi Boknows, Sounds like a future athlete there 😉

Very helpfull!!! , thanks dude!

I am 15 and got my trek Marlin 5 a couple years ago. I have ridden some insane tracks on it and haven’t really had any issues. The only thing I’ve broken so far is the derailer hanger but apart from that nothing. I use it for riding on streets, dirt roads and mountain bike tracks of different difficulties including black diamond tracks. It is still working great and I would think of it as a good bike. I found that the seat post was originally at my good pedaling height when I got it at its lowest point but have now upgraded that to dropper.

Hi Jayden, Have you tried getting a regular maintenance check with your local bike shop? Regular maintenance check can help prolong the life of a bike 😉

I bought a 29″ blue Marlin 5 for my son’s 14th birthday 16 months ago and initially I really liked it. But, it’s been a flaming pile of broken parts since then. My son doesn’t abuse this bike (no downhill or big jumps) and mainly rides a few miles into town and occasional wheelies. Since new here’s the things that have broken on it: rear shifter cable, rear axle, right pedal stripped out of crank arm, left pedal stripped out of crank arm, rear axle again, right pedal stripped out of crank arm again and the chain broke (which pulled the rear rerailer into the spokes and ruined it). Our closest Trek dealer is an hour away so running to the bike store is a real issue but they have been pretty good about helping me out. I’m a metal fabricator and part time motocross bike mechanic so I have a good background in metals and how they should operate. I honestly feel Trek has build a cheap bicycle with metal parts using allows that aren’t appropriate and as thin as materials as possible to save weight at the cost of reliability. I just called Trek directly and we’ll see where that goes.

Hi Dough, Sorry to hear about your experience. It looks like your drivetrain and the whole groupset have issues. Usually these are the most abused parts of the bike and an upgrade to better parts will do better. However I am curious as to what they will tell you. Let me know about it. Cheers!

This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. The larger frames (M and up) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.

Loved the world over, Marlin has long held hearts of new riders and seasoned rippers alike, and to keep everyone rolling with ear-to-ear grins we’ve revamped it with more trail confidence than ever. Whether zipping through town, dipping your toes into the trail for the first time, or slicing through switchbacks as a well-seasoned rider, you’ll appreciate the sleek new frame that ups the capability and brings looks to match. There’s a reason it’s always been your favorite.

Total trail confidence A bike's geometry is the defining framework it's built on, and Marlin is a true mountain bike at it's core. Its measurements are perfectly dialed to give you a confidence-inspiring, planted feel when you’re rolling down steep and bumpy trails, while keeping it easy to pedal back to the top when you’re ready for another lap.

Marlin’s head tube (a) sits at a slacker (more acute) angle. The slacker head tube angle (b) moves your front wheel farther in front of you. Take it to the trail, and this slacker head tube angle (b) boosts stability and control for confidence when descents get steep and rowdy.

To balance a slacker head tube angle (b) , Marlin features a steeper (more upright) seat tube angle (d) . A steeper seat tube (c) lets you get the most out of every pedal stroke, so you don’t waste power on the climb to the top.

Marlin is equipped with a short stem and wider handlebar for more direct control and responsiveness when you’re maneuvering through rocks and roots. Meanwhile, a longer reach (e) gives you extra stability so you can ride faster and more confidently.

Secure your ride

A new Thru-Skew axle provides better rear wheel security, holding your wheel in place snugly and ensuring it doesn't slip out of the frame, even when you're rolling through rough-and-tumble terrain.

Fully guarded

Full-length, full-coverage guards on the chainstay protect your frame and keep your ride quiet.

Float on the trail

Big 2.4˝ tires elevate traction, so you stay planted on dusty switchbacks. But not only do bigger tires give you more grip — they also soak up bumps for a smoother ride.

Upgrade ready

With a frame this nice, you won’t want to part ways with your Marlin as your skills grow. Marlin Gen 3 is upgrade-ready, so you can upgrade your bike when you upgrade your skills. New internal cable routing lets you install a dropper post — and sizes XS and up can be upgraded to a bigger, 120mm fork when you’re ready to take on bigger trails.

A bike for everyone We believe that ever rider deserves a well-fitted bike, that’s why Marlin is available in every size from XXS to XXL — and even an “extra-medium” size for riders who fall in between a medium and large. Each size is tuned to its riders, with Smart Wheel Sizing that scales the wheel size with the bike size, so every rider has comfortable stand over height. Smaller, XXS, and XS frames also feature a curved top tube to boost confidence and make getting on and off a breeze.

Make Marlin yours Whether you’re ripping up the trail on the regular or a rugged city commuter, your Marlin can be fully customized with a treasure-trove of accessories. From kickstands and grips to bottle cages and bags, you can turn your Marlin into the perfect bike for your everyday ride.

• Deck out your Marlin

Trek warranty & backing We believe that when you put your heart and soul into something, you should have the stomach to back it up. That’s why we stand behind all Trek bikes with a limited-lifetime warranty. From your first ride to your 500th, we’ll be here for you in the unlikely event that something goes wrong with your Marlin. All you have to do is stop by your local Trek store and you’ll find all the support you need to get back spinning in no time.

The Marlin family Both generations of Marlins are true mountain bikes aimed at the rider who wants a versatile hardtail capable of off-road singletrack or in-city missions. Both generations have a 100mm travel suspension fork and 29” wheels on most sizes except for smaller sizes with proportionate suspension travel and wheels, thus making it a great bike for shorter riders as well.

Marlin Gen 2

Get all-around versatility on Marlin Gen 2. It fits up to 2.2˝ tires, and features balanced, neutral geometry that keeps you comfortable and in control as you venture off road.

Marlin Gen 3

Get serious trail capability with Marlin Gen 3’s bigger, 2.4˝ tire clearance, internal dropper post routing, and a stiffer and more secure ThruSkew rear axle. Plus, its updated longer, slacker geometry gives you a boost in stability on steeper trails and at higher speeds.

Looking for something more to fill your singletrack appetite?

If you’re itching for a lighter weight, even faster hardtail, X-Caliber is your ride. It’s light, sleek, and efficient — perfect for new riders, cross-country racers, and anyone who wants to cover a lot more trail miles in a lot less time.

Roscoe delivers the capability of a full suspension trail bike in a simple hardtail package. The laid-back geometry that gives you tons of stability on rowdier trails, and it rolls on big 2.6˝ tires that give tons of traction for getting through rough and tricky sections of trail.

A bike with lower gearing will be easier to ride up steep hills, while a higher top end means it will pedal faster down hills.
