Trek 3700 Mountain Bike Review: Worth Every Penny?

If you are a serious mountain biker who’s looking for a reliable yet affordable bike for his next trip – then our Trek 3700 review will help you find a new option.

The 3-series bikes from Trek are some of the best-selling mountain bikes in the world. The Trek 3700 is easily a top-notch choice for those who can’t afford a high-end bike. This makes it a lot more desirable for many people, and easily the first choice for those who have experienced their quality before.

But the appeal is not only in the Trek 3700 price, which rounds the 450$ – but in the quality of construction. Coming with a 100mm-travel suspension fork, mechanical disk brakes, and a decent frame – the Trek 3700 Alpha is a beautiful pick for anyone.

Advantages of the Trek 3700 Mountain Bike

Incredible Reliability

The reason the Trek 3700 is maybe the best-selling bike for mountain lovers is that it is not only cheap but incredibly reliable. And even better than that, the Trek 3700 is a bike that demands little to no maintenance when using.

With a simple cable change, clean and lube, and brake pad replacement, you will be able to use and re-use the Trek 3700 as many times as you want. All of this considering the many times it passes over bumps, the knocks over stones, the number of miles, and how many drops it can resist.

This is all thanks to how Trek decided to make not a design-oriented bike that looks amazing for the high-end user, but a simple-looking yet highly reliable mountain bike for the low-end user.

With the Tektro Novela brakes you can maintain the brakes mud-free during your adventures, and with the Shimano Tourney shifters & levers, you can use eight different speeds at 24 different gears for superior versatility.

The Trek 3700 merely is designed to provide valuable reliability while riding and a highly versatile performance when needed. For an outstanding price – the Trek 3700 is easily a top-notch option for anyone.

Outstanding Frame

Short frame for the beginner user, with a pragmatic shape for the lover of good, reliable mountain bikes – that’s what the Trek 3700 offers.

It’s not a bike design for everyone, but almost.  It fits practically any body shape, length, and form. The 3-series bikes from Trek are light, low-maintenance, and highly comfortable so everyone can use it without problems.

The frame is the Trek Alpha Aluminum. This frame with aluminum tubes shaped with the perfect short form. This compromises off-road performance slightly, yet it makes it one of the most reliable at its price.

The cross-oval down tube of the frame makes it more rigid on the backbone, yet meeting the butted head exactly where it needs to avoid extra-strengthening without compromising build quality. And at the rear, you will find the wishbone seat stay –a traditional Trek design– which is the only part of the Trek 3700 that is more aesthetically-driven than reliability-oriented.

Superb Gearing System

Then you have the Suntour coil-sprung XCN forks. 30mm stanchions and 100-mm travel, for versatile design, and twin adjusters for easier adjustment depending on your desirable experience – aggressive, heavy, slow, comfortable, etc.

The coil-sprung forks are maybe the smartest part of the bike. Not only because they help beginners to adjust the bikes according to their needs, but also help those most aggressive and experienced riders to get the most out of it.

To finish a reliable, simple yet very versatile design – you can add the full-set rear rack, the mudguard mounts, and a 14.5 KG weight, easy handling and even more straightforward conversion for lighter uses when needed. Naturally, it is a bike for the not-demanding experienced user and the beginner, which will provide more reliability and comfort than anything else.

Top-Notch Additional Equipment

The additional parts of the Trek 3700 offer decent performance with a fantastic affordability.

In the brakes, we can find the Tektro mechanical disk, perfect for all-weather activities and more responsiveness.

Then we have Shimano 8-speed transmission that combined with the Bontrager LT3 tires will help you get more versatility and better grip during calm &easy trails.

Finally, the formula DC wheels and the Bontrager handlebars with the saddle and seat post only contribute to even better comfort and reliability. For an affordable price, there’s just not much to complain about.

Disadvantages of the Trek 3700 Mountain Bike

Hard Handling When Going Downhill

When you use it on a steep or a falling track where you need faster performance, the bike compromises grip for comfort. You will be sitting on the bike without being able to take high risks, as the design not only makes it harder to get a good grip in front but also harder to brake when needed.

Weighing in as an experienced biker is easy when you know how. However, if you are a beginner, especially on a bike like this, maneuvering can get out of your hands, primarily through fast rocky trails.

The weight distribution of the 3700 will make it harder to weight up in the front to grab more grip. If the fork were shorter than it is, it wouldn’t be a problem. However, it’s still not the worst design for a beginner – unless you are looking for a more performance-oriented bike and you’re willing to learn how to use it correctly.

But that does not mean the Trek 3700 is poorly made or that it is not reliable when riding through fast tracks. It’s just that it is not the most grip-oriented and secure option for those who are looking for superior performance.

The whole purpose of having a mountain bike is to be able to maneuver and handle whenever possible, not only to get more fun & adrenaline through the hardest of tracks but also to avoid accidents when needed – which the Trek 3700 doesn’t offer entirely.

But the brakes are enough, the suspension is highly reliable, and the design pretty comfortable. This is perfect for the calm biker, who’s not looking for more than just pedaling and resisting some bumps in slow, fast tracks.

If you are someone who loves rugged adventures, the 3700 may not be the best option for you. The geometry and built of the Trek 3700 will help you have a great time during the calm parts of your trips – but during the fastest, funniest, and adrenaline-driven moments – you may not find it suitable.

Not the Best Bike for Experts

The 3700 is not a bike without downsides. Yes, it is solid, newbie-friendly, and highly comfortable. But despite its short cockpit for beginners, the spare headset, and the rise steam – it creates the comfortable, yet straightforward position all inexperienced bikers look for, but not the design experienced mountaineers need.

It’s comfortable, yes. It’s easy to use, yes. But is it manageable and handling-oriented? Not really.

The Trek 3700 Alphaisbuilt merely for the newcomer or the not-demanding user. It won’t be the most satisfying or the most adequately made if you are an experienced user, but will quickly help you learn how to mountain if you are a beginner.

It is fun, simple, and traditional in its design. A ride with the Trek 3700 is more comfortable than with any other high-end bike you may find. It comes with a hard-tail platform, a rear suspension, pivoted swing-arms, and the adjustable damping – excellent for both beginners and experienced users who want easiness before anything else.

Experts, however, will find it too faulty for their liking. Especially those who love off-road adventures before anything else.
