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 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, powerful hydraulic disc brakes, and a suspension fork that takes the edge off bumps and rough terrain.

The final word

It’s built in Trek's MTB heritage, so you get 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.

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. Marlin models in XS and S frame sizes have a curved top tube and a lower standover height that makes it easier for smaller riders to mount and dismount
  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


Features

Will my bike have a curved top tube?

Will my bike have a curved top tube?

Smaller frames (XS and 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 ML) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.

High tech, high value

High tech, high value

Marlin looks and feels great. It’s packed with features usually found only on more expensive bikes, like a stylish frame with internal shift cable and brake hose routing, which can help your cables last longer by protecting them from the elements.

Fit for every rider

Fit for every rider

Marlin comes in seven frame sizes to suit riders of any height, and Smart Wheel Size ensures you’re on the fastest wheel that fits. The smallest sizes even come with short-reach brake levers and narrower handlebars that give smaller riders better comfort and control.

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.
