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
A lightweight aluminium frame with internal routing to protect your cables and add to the bike's sleek look, powerful hydraulic disc brakes and a simple 1x10 Shimano drivetrain that ditches the front derailleur for less clutter and easier operation. The wide-range cassette still gives you all the gears you need for big climbs and steep descents. Plus a suspension fork with a lever that lets you easily lock the suspension so you don't waste energy on smooth terrain.
The final word
The Marlin 6 gives you upgrades that you'll notice on every ride, like the smooth, simple shifting Shimano drivetrain. Extra-strong double-walled rims and powerful hydraulic disc brakes give you durability and stopping power for your most rugged adventures on the trail, in town, and everywhere in between.
favorite_borderWhy you'll love it
- The 1x drivetrain gives you all the gears you need, and none you don’t
- Smaller frame sizes (XXS, XS and S) have short-reach brake levers that make it easier and more comfortable for riders with smaller hands to brake confidently
- The Marlin models in XXS to S frame sizes have a curved top tube and a lower standover height that makes it easier for smaller riders to mount and dismount
- 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
Will my bike have a curved top tube?
Smaller frames 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. Larger frame sizes have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.
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 shift cable and brake hose routing, which can help your cables last longer by protecting them from the elements.
Locked suspension means your fork remains inactive, increasing pedalling efficiency. Perfect for extended road sections where efficiency is more important than bump absorption.
Going for a long ride? Rack mounts make carrying accessories a breeze.
Internal cable routing
We route shift and brake cables through the frame to keep things clean and simple. And it looks great, too.
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.
