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 Alpha Silver Aluminum frame with internal shift cable and brake hose routing to protect your cables and add to the bike's sleek look, 21 speeds, a wide range of gearing so you always have the right gear for your terrain, hydraulic disc brakes that feel smoother than mechanical disc brakes, and a suspension fork with 100mm of travel—that's the same amount favored by most cross country racers.

The final word

It’s built in Trek's MTB heritage, making it more than capable of taking on trail 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.

The Walkthrough

favorite_borderWhy you'll love it

  1. 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
  2. Smaller frame sizes (XS and S) have short-reach brake levers that make it easier and more comfortable for riders with smaller hands to brake confidently
  3. It has separate brake and shift levers (a feature that's common on more expensive mountain bikes) so you can fine-tune the positioning for comfort
  4. Rack and kickstand mounts make it easy to accessorize, so your mountain bike can double as a rugged commuter
  5. Like every model in the Marlin family, it's backed by Trek's lifetime warranty

"Look fast, feel fast, go fast."

"Unlike some bikes on the cheap end of the spectrum that cater to the recreational user, this one is aimed firmly at entry-level riders who want a bike that's affordable yet capable of riding and racing hard."

Sizing & fit

The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
