It's right for you if...
You're testing the waters of off-road riding, and want a real mountain bike at 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 Aluminium 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 100 mm 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
- The 2x drivetrain gives you all the gears you need and none you don’t
- 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
- It has separate brake and gear levers (a feature that's common on more expensive mountain bikes) so you can fine-tune the positioning for comfort
- Rack and kickstand mounts make it easy to accessorise, so your mountain bike can double as a rugged commuter
- Like every Trek, it's backed by a lifetime warranty
Features
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.
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 cable routing, which can help your cables last longer by protecting them from the elements.
Rack mounts
Going for a long ride? Rack mounts make carrying accessories a breeze.
Suspension lockout
Locked suspension means your fork remains inactive, increasing pedalling efficiency. Perfect for extended road sections where efficiency is more important than bump absorption.
Rear kickstand mount
Chainstay mounts make it easy to install a rear kickstand that stays out of your way and supports bikes of all sizes. No more laying or leaning.
Blendr stem
Bontrager stem technology lets you clip your gear directly to the stem for clean looks and maximum user friendliness.
