It's right for you if...

You're testing the waters of off-road riding, and want a real mountain bike at a great value, with a wide range of gears to cover more ground on the road and trail.

The tech you get

The heart of Marlin 6 is a lightweight Alpha Silver Aluminum frame with internal routing to protect your cables and add to the bike's sleek look. It has an efficient 2x8 drivetrain, hydraulic disc brakes that feel smoother than mechanical disc brakes, and a suspension fork with 100mm of travel and a lockout feature that lets you temporarily lock the suspension for better efficiency while climbing.

The final word

Performance features like suspension lockout, stronger double-walled rims, and hydraulic disc brakes. It's also equipped with rack and kickstand mounts and a wide range of gears. These design details make it a great choice if your mountain bike doubles as your commuter.

favorite_borderWhy you'll love it

  1. The 2x drivetrain gives you all the gears you need and none you don’t
  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

Features

Internal cable routing

We route shift and brake cables through the frame to keep things clean and simple. And it looks great, too.

Rack mounts

Going for a long ride? Rack mounts make carrying accessories a breeze.

Smart Wheel Size

The right wheel size paired with your frame size gives you the perfect combination of responsiveness and control.

Suspension lockout

Locked suspension means your fork remains inactive, increasing pedaling efficiency. Perfect for extended road sections where efficiency is more important than bump absorption.

Extended size range

A wider range of sizes than the industry standard provides more option for everyone, from tallest to shortest and all those in between. Because everyone deserves a great ride.

G2 Geometry

Advanced frame geometry and a custom offset fork give our 29ers precise handling at low speed without compromising high-speed stability. We call it G2 Geometry, and it's why our 29ers handle better than anyone's.

Alpha Silver Aluminum

Our proprietary lightweight aluminum is continuously cold extruded to a single wall thickness for durable performance.

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.
