Things to Keep in Mind while Selecting a Mountain Bike

When selecting a mountain bike, it is critical to evaluate numerous aspects to guarantee that you choose the best option that meets your expectations. The following factors require careful consideration:

• Frame material: When it comes to a bike’s structure, the frame is critical because it directly affects the bike’s endurance, weight, and overall feel. The materials commonly used to build bike frames are steel, titanium, aluminum, and carbon fiber. Carbon fiber frames are lighter and more rigid, but they are also quite costly. Meanwhile, steel frames are sturdier but weigh more.
• Suspension: Mountain bikes are equipped with varying types of suspension, which include hardtail, full-suspension, and rigid. While hardtail bikes have suspension on the front wheel only, full-suspension bikes offer both front and rear suspension, and rigid bikes have no suspension at all. Hardtail bikes are well-suited for cross-country rides, while full-suspension bikes are ideal for traversing rough terrains.
• Wheel size: Bicycles have varying wheel sizes like 26″, 27.5″, and 29″, each with its own advantages and disadvantages. The 29″ is the most popular wheel size among cyclists due to its excellent stability and traction. On the other hand, the 26″ wheel size is perfect for maneuverability, while the 27.5″ option provides a balance of both maneuverability and stability.
• Brakes: Brakes are an essential component of a bicycle and they are available in various types. Two primary types of bicycle brakes are disc brakes and rim brakes. Disc brakes are more powerful than rim brakes and can operate efficiently in any environmental conditions. On the other hand, rim brakes are comparatively lighter in weight and more cost-effective.

When choosing a mountain bike, factors such as frame material, suspension, wheel size, and brakes must be considered to make an informed decision.

Is Trek 3900 Mountain Bike A Good Bike? [Trek 3900 Review]

Table of Contents

The Trek 3900 is a mountain bike in the Trek 3 series. In 2005, it was only $329.99. It falls under the category of low-cost mountain bikes. But it’s a mountain bike that will be with riders for the next ten years. It is worthwhile to spend the time learning about it.

In the past, we’ve seen a lot of low-cost bikes put in a lot of effort in terms of price/performance and durability. And the Trek 3900’s durability is unquestionable.

Below, I’ll go over the descents and climbs of this mountain bike, as well as its component features and comparisons to other mountain bikes. Giving you a bird’s-eye view of the Trek 3900.

To be more specific, the Trek 3900 alpha isn’t a particularly fast mountain bike. It’s designed for normal mountain riding, but because mountain riding can’t be avoided, long descents are included. With only 70mm of fork travel, the Trek 3900 is prone to bottoming out if you come across large rocks or roots on the descent.

The 2.0″ tires deflected easily during the descent, which was a little uncomfortable. The difficulty is further reduced, and the trail’s descending surface is much more comfortable. This is also a once-in-a-lifetime riding opportunity.

The Trek 3900 excels on hill surfaces, and in hilly areas with high and low rolling terrain, gripping the grips can climb small slopes of about 20° very quickly, and with the 3X8 drivetrain, it’s not easy to strain.

It is not always a good experience to want a fast and painful slope; after all, the 26″ tires will always feel a little lacking in transmission when compared to the current 27.5″.

Of course, another important reason is the weight of the body; if you complain about this, you are being unreasonable; after all, it can do more than $300 stacked out of the accessories. As a result, it will only climb on less technically difficult trails.

General pavement

When riding on normal brick-laying or hard-packed surfaces, the Trek 3900 performs reasonably well in comparison to most cheap mountain bikes. The 3X8 drivetrain has a wide enough range of shifts. It’s also very difficult to encounter difficult terrain when riding on city streets.

The park’s wooded areas provide the best opportunity for the Trek 3 series 3900 to perform well, easily passing through cobblestone surfaces or surfaces with some potholes while not interfering with the rider’s ability to ride the entire bike.

The muddy dirt, as long as it’s not too soft and you don’t run out of kinetic energy pedaling, is perhaps the highlight of this mountain bike.

Component Features

Alpha silver aluminium frame.

The Trek 3900 mountainbike is less bulky thanks to the Alpha Silver Aluminium with the semi-integrated head tube, and the double oval downtube with integrated corner stays adds style to the overall design. It is also designed with a greater emphasis on the down tube’s role as a support when climbing ramps.

The slight bulge in the rear insert also allows for larger tire size. A wider 2.2″-2.4″ tire, which is compatible with the Trek 3900 frame, may be considered for more mountain riding. Flat welds have not lost the soul of a good mountain bike.

The 3X8 drivetrain

The older 3X7 drivetrain has fewer gearing options than the 3X8 drivetrain. This is still lagging behind the latest Trek mountain bikes. However, given the asking price, it’s a good value match for the accessories. While many riders consider the Shimano Altus and Shimano Acera M360 to be low-end, they must admit that they are durable.

When it comes to climbing, the right gearing can make or break your ride. In an entry-level mountain bike, a 3X8 drivetrain is still considered a relatively high configuration. The alloy guide wheels, too, don’t feel cheap, and the smooth movement contributes to the ease of use and simplicity.

If you don’t think it’s too much to go after full mountain bike performance, the Trek 3900 drivetrain is a better choice at this price point.

Tektro linear-pull brakes

The Tektro linear-pull brakes are on the low end of the spectrum, and while they are the bike’s mainstay, I couldn’t brake well on fast descents. That is the disadvantage of these brakes.

Of course, if your primary purpose for purchasing it is not strenuous mountain biking, the Trek 3900 brakes are superior. The simple and straightforward rim brakes make riding on flat roads very comfortable, and the mechanical operation and crisp braking that requires some travel also allow you to ride more freely on trails or forest roads. This component isn’t ideal, but with its upgraded Trek 3900 Disc, these annoyances can be avoided.

Fork in the front The Trek 3900 has a fork with only 70mm of travel, the InSync Grind 1. This is adequate for general mountain riding, but not so much when the difficulty level increases. A shock fork with such a short travel is only found on entry-level mountain bikes for youth riding.

And the fork travel on the Trek 820 mountain bike currently on the market is only 75mm, which is slightly more than that but still insufficient for trail riding. As a result, it is appropriate for general trail or rough road riding, and the shock absorption effect of the fork is excellent and will not fail to function.

Tires and wheels

The Bontrager LT3 tires are the same as those used on the Trek 800, which was released at the same time. 26″x2.0″ tires have a greater increase in handling flexibility and provide excellent traction on normal surfaces, but not necessarily in wooded areas after rain.

However, the grip on rough terrain is compromised. Although I prefer wide tires, many Trek 3900 owners have complained about the original size being narrower. Of course, this is upgradeable; as previously stated, it can be the widest and support 2.4″ tires, making your ride on the wet ground a better experience.

Rack and fender mounts

The Trek 3900 can be outfitted with racks and fenders to transform it into a short-distance commuter. Better storage space is required for touring rides. This could be a reason to consider riders who use it primarily for commuting rather than difficult mountain rides.

Other versions of the Trek 3900

Trek 3900 disc.

The original cheap rim brakes have been abandoned in favor of a more cost-effective mechanical disc brake. The rest of the kit doesn’t change much.

Comparison Table

Trek 820 mountain bike vs trek 3900.

Despite the fact that the Trek 3900 has been discontinued, it still offers more benefits than any other mountain bike in the same price range. I compared the Trek 820 mountain bike to the Trek 3900 here. There are numerous distinctions between them.

The Trek 820 has a steel frame, SR Suntour shock fork with 75mm travel, and a 3X7 drivetrain. They all have the same thing, of course: alloy cable pull brakes and 26×2.00″ tires. The Trek 820 is a good alternative to the Trek 3900. It is slightly heavier by 2 pounds and has a standard 3X7 drivetrain with an extremely loosehead tube angle for comfortable mountain riding.

So, when comparing the two, I prefer the ruggedness of the Trek 820, and its use is more suited to the needs of commuter riders. One of the best sports is perhaps the occasional mountain ride.

Trek Marlin 6 mountain bike vs Trek 3900

In terms of accessories, the Trek Marlin 6 is a little more modern than the Trek 3900. Starting with the extremely popular body color scheme, the smooth and clean internal alignment, and the comfortable head tube angle, it is the body design that mountain riders adore.

If you want to become an adventurous everyday rider, the Trek Marlin 6 is ideal. The Trek Marlin 6 has a 100mm (80mm on some frames) travel fork, making it the entry-level shock fork for trail riding when compared to the Trek 3900. There are also safer and more efficient hydraulic disc brakes available, which allow for quick braking with a flick of the finger.

The now-popular 1X10 drivetrain eliminates the obsolete front derailleur chainstay, allowing entry-level riders to ride without feeling the complexity of the setup and be more confident mountain riding and challenging technical trails.

The Trek Marlin 6 costs less than $1000 but outperforms the Trek 3900 in a variety of configurations. The Trek Marlin 6 mountain bike is well worth a look if you want to be an everyday adventurer in mountain riding.

The Trek 3900’s configuration leaves avid trail riders tasteless and ready to try a high-end trail mountain bike. In fact, the comparison of these two mountain bikes just made me more conscious of how big the gap is between a professional cross-country mountain bike and a casual “toy”.

Final Verdict (4.5/5)

At a low price for entry-level mountain riding needs, the Trek 3900 is a mountain bike stacked with relatively low to mid-range accessories for the time. Able to ride in normal mountain terrain. More than anything else commuter riders would prefer them.

All in all the Trek 3900 is a very good entry-level mountain bike. Rating: (4.5/5)

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.

Check out Moscow’s NEW electric river trams (PHOTOS)

Water transportation has become another sector for the eco-friendly improvements the Moscow government is implementing. And it means business. On July 15, 2021, on the dock of Moscow’s ‘Zaryadye’ park, mayor Sergey Sobyanin was shown the first model of the upcoming river cruise boat.

The model of the electrical boat with panoramic windows measures 22 meters in length. The river tram - as Muscovites call them - has a passenger capacity of 42, including two disabled seats. The trams will also get cutting edge info panels, USB docking stations, Wi-Fi, spaces for scooters and bicycles, as well as chairs and desks for working on the go. The boats will be available all year round, according to ‘Mosgortrans’, the regional transport agency. 

Passengers will be able to pay with their ‘Troika’ public transport card, credit cards or bank cards. 

The main clientele targeted are people living in Moscow’s river districts - the upcoming trams will shorten their travel time in comparison to buses and other transportation by five times, Mosgortrans stated. 

As the river trams are being rolled out, Moscow docks will also see mini-stations, some of which will also be outfitted with charging docks for speed-charging the boats.  

Moscow is set to announce the start of the tender for construction and supply in September 2021. The first trams are scheduled to launch in June 2022 on two routes - from Kievskaya Station, through Moscow City, into Fili; and from ZIL to Pechatniki. 

“Two full-scale routes will be created in 2022-2023, serviced by 20 river trams and a number of river stations. We’ll continue to develop them further if they prove to be popular with the citizens,” the Moscow mayor said .

Customer Reviews

Battery compartment design is weak. I have anther Moscow and ot would come lose on top. Screws are so small. I also woul brace the battery with strap due to rattling. Otherwise love my moscow

We purchased the NCM Moscow 29 E bike from Leon Cycles earlier this month. Communication was via 'Whatsapp' which I initially thought a little odd but worked out well. Once communication established the transaction was completed quickly and easily. We were able to arrange for the team to assemble the bike for us and we picked it up from the warehouse without an issue. We love the bike and are continuing to find new places to discover using it. Competitive price and great service.

I ordered the bike 4 days ago and today it arrived. Now my first impressions: it is easy to assemble, looks great, is cleanly finished and after a first short driving test I have to say, the hammer. It's totally easy to drive. If it stays that way, I can only say thank you Leon Cycle. Now I can cycle again, despite knee problems. Price-performance top

Great bike, this is my second e bike and by far the best. Watching e bikes over the last 10 years I think the Moscow 29er is fantastic. I live in the Dandenongs outside Melbourne with big steep hills and the Moscow takes them all on with great pulling power and gear range. 48v with 16 amps means over 750 watts of power. The bike is big and serious so getting on and off can be tricky but you do get used to it. With the previous bike (36v at 8amps) I was scared of running out of battery on a big hill and having to push the bike home but not with the Moscow. Also if you take the front wheel off you can get it in a hatchback like my Mazda 3 Which is nice. At $2200 it is a great buy.

Purchased two Moscow 27.5. One for my wife, one for me. Fast delivery, well boxed and easy assembly. Absolutely FANTASTIC to ride and use. Great range, and enough power for steep hills and tough terrain. I highly recommend them. Exactly as advertised and brochure. Looked at many options from other suppliers but these are the best value for money. If anyone wants a little extra range and a few more features then a Moscow Plus may suit. 48 Volt is the way to go. Great support and assistance from the team at Leon to make the right purchase decision. Hope other people may enjoy the ride and quality product. Harry G
