Terrain Adaptability

The Trek 3900 mountain bike performs reasonably well on general pavement and city streets. However, its true capabilities shine on off-road trails and uneven terrains, thanks to its front suspension and knobby tires.

Be sure to visit your local bike shop for tune-ups and component replacements if needed. For city streets riding or daily commutes, the Trek 3900 comes with disc-compatible dropouts and fender mounts.

While the Trek 3900 may not be the most advanced mountain bike on the market, it is certainly a durable and reliable option for beginners and intermediate riders. In our opinion, with proper care and maintenance, the Trek 3900 is well worth the investment.

Frame is absolutely solid

Most components especially the Suntour forks are garbage.

First bike after many many years away from riding. As soon as I bought it, I hooked up with many real MTBers. This bike of course was far below the standards necessary, but it took a tremendous beating along the way. I quickly broke most of the cheapest components and upgraded and replaced them until almost nothing origninal except BB and seatpost clamp were left on the frame. Rockshox Reba RLT and XT components all the way around and finally retired the frame as I upgraded to a BMC carbon Full suspension. I am putting back together to use to ride with the kids around the neighborhood. Overall, it was a great entry level bike to get me back in the sport and outperformed what it was made to do, at least for me.

Similar Products Used:

Awesome frame

Cheap compoments, all bikes should've came with disc brakes. The saddle, and peddals.

Great bike for the price. Haven't really done any hard riding, but overall it feels great. I got the one with V type brakes and made the disc conversion myself and it was fairly easy. I replaced the wheels with lighter disc type wheels, replaced the crankset, pedals, front and rear dérailleurs, shifters, brake levers, grips, and saddle. All I need now is a new fork.

For under $500, you get yourself a lifetime-warranted frame! The newest version has a zero-stack headset, pretty decent components, and disc brakes. The factory components are ok, if you do not ride too much trail or gravity. The bike is upgradable.

Wheels and fork are absolutely rubbish, but that is true across the board at this price.

Nice bike to get you rolling, which you can upgrade as you go. The geometry is friendly and is middle-of-the-road enough to accommodate any riding style.

Diamondback, Gary Fisher, etc.

Price... Even new, the price is pretty good for a mountain bike of reputable quality. It's also upgradable. The bike is built like a tank. I've been ragging on mine for several years now and have done some pretty intense riding with it, and it is still holding together with the original components.

Weight... this is largely due to the front fork and rims. I have upgraded the rims to something lighter and replaced the pedals with shoes... I'll probably upgrade the fork to something lighter in the near future.

A solid bike for a beginner/amateur with plenty of room to grow.

Gary Fisher Marlin

everything but the tires and shifting

Tire rims, gear shifting

This bike is good on the highway. Other than that it is not related for trails. Did a little 180 spin and bent the rim on the bike and i havent even had it for a month sadly. I recommend this bike just for highways. The bike shifts ok it sometimes does skip but doesn't do it to often.

The frame stays in one piece

Everything else

If you want to get serious about mountain biking, avoid the 3-series at all costs. A 4300 is more suitable if you want to get into mountain biking. Otherwise, the best a 3-series such as the 3900 will be good for is the occasional light trail use, but mostly paved bike path use. For those who simply ride casually once in a while. I'm ashamed to call it a mountain bike with the components it has. Most ambitious and adventurous kids will outgrow this bike quickly.

crappy Chinese bikes from department stores

Frame, disc brakes, shifters

Handle bars, fork, pedals, rear derailleur

This is a great entry level bike. I have flat out abused this bike for 3 weeks now and have only had to replace the bars. It does have week components, but I didnt purchase the bike expecting it to perform on the same level as a thousand dollar bike. I bought it to get me started, and I plan on upgrading to better components as the factory ones wear out. All in all you cant ask for much more for the money.

Strong Frame, Smooth, Cheap, Upgradeable platform.

Handle Bars, Stem, Grips are terrible. Rear Derailleur. Seat post slides down a lot.

I have had this bike for 5 years now, I have been riding it abusively as a trail rider for 2 years now. This thing is a battle tank. I did a good bit of modification to it because i can. I love this bike and the only reason for not using it anymore is i am riding a 29er now. This is a great bike for a beginner and will last through some abuse. I am 5'10" and 180 lbs, but the bike would fit someone 6'0" like a glove. I highly recommend new grips and a lighter and shorter replacement for both the stem and handlebar.

The Al frame.

Components, weak fork.

I've been riding my road bike primarily for the last few years and a friend I ride with started to get into single track. I had hoped to find a cheap, decent bike with a broken fork or some other damage that i could fix easily. As it turned out, someone traded this bike to my brother for some work he did. He cannibalized the front wheel, handlebar, tires, and seat. I told him my plan and he gave what was left to me. I was lucky enough to have an old front wheel from my 820 that I used as a stop-gap, found a used 620mm straight bar for 15 bucks, NOS (2009) BB7s for 44 dollars, a Deore RD-M770 for 60, and someone who would trade my wheels for a set of disc wheels that were on a non-disc bike that he was giving away. So, so far, this bike has cost virtually nothing for the quality that I'm left with. I plan on sinking a fair amount of money into a model year or two NOS fork of some kind very soon and it should be about perfect for what I want to do with it. So that is a major advantage of this bike. If it can be had for very little money, it can be upgraded fairly easily! The stock rear derailleur is a crappy acera; when I had it off road the chain would slap like crazy and I even had it leap gears. since the frame can accept disc brakes, I replaced the cheap, cheap V brakes and it stops like a champ now. The front fork is also very weak on the 2007 model that I have (Spinner Grinder 1... I can't even find documentation for this POS) and it bottoms out on virtually anything I do (keep in mind that I have a road bike that i use for just about any road-like riding). Now it shifts and stops like a dream and after I get a fork it should be ideal for anything but racing (it is not a very light bike). It's already been a blast for single track. So, would I recommend it? If you have the money for something better, get it. But if you don't get this and upgrade as you go! If you can get one for free (or very nearly) grab it up and take advantage of the frame. In short, I recommend it, but my recommendation is heavily qualified.

Trek 820, Y33

A good solid bike. If you like hitting the trails a lot but don't really have the budget, this is the bike for you. The fork is good for light trails but it tends to bottom out when the trail gets nasty. The tires are pretty good for both the road and dirt. The bike was actually designed pretty well and most of the components on the bike will definitely do if you are not looking for top performance. If you want to bring out the bike's potential, you might want to consider shelling out an additional $200 or so for upgrade parts.

It's a little heavy for a hardtail. I have a full suspension bike that is a little lighter than this. That says a lot considering hardtails are supposed to be lighter. I have the white version of this bike and dirt sticks to it like anything but that's the price I get for getting anything white, right? Stock brakes are pretty bad so you might want to replace them with at least entry level Shimano brake calipers and discs like the Non-Series BR-M416. That will definitely help with the braking.

It's a pretty good bike. The stock shifters did a pretty good job until I decided to upgrade. The stock brakes are pretty bad. poor stopping power and I constantly had to adjust the setup. I think I would have been better off with rim brakes considering how bad the Promax disc brakes were. I decided to replace the braking system with an entry level hydraulic system from Shimano. That made all the difference. Braking power is fantastic and modulation is all there. Next project is to lighten up my front end by replacing the stock handlebar and stem to carbon fiber parts and perhaps replace the stock suntour front suspension to something with hydraulics. Bottom line is that if you want to get a good bike on a budget, this is the one for you. Shell out and additional $200 for upgrades and I can guarantee that you will be a very happy camper.

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.

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)
