Marlin 5 is a trail-worthy daily rider that's perfectly suited for everyday adventures, on and off the trail. A front suspension fork with 100mm of travel, 21 speeds, and mounts for a rack and kickstand make it an ideal choice for new trail riders or anyone looking for a comfortable, stable commuter with the ruggedness of a real mountain bike.

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 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.

Why you'll love it
- 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
- 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 shift 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 accessorize, so your mountain bike can double as a rugged commuter
- Like every model in the Marlin family, it's backed by Trek's lifetime warranty
