Marlin 4 is the gateway mountain bike that will take you from rail trails to singletrack. It's ideal for riders who want a mountain bike with knobby tires that can double as a rugged commuter. Disc brakes, front suspension, Shimano 14-speed shifting, and mounts for a rack and fenders make this a great bike for trail riders and campus commuters alike.

You want an introductory mountain bike at an incredible price, but also want a commuter that's rugged enough to hop curbs on the way to class.

A lightweight aluminum frame with internal routing to protect your cables and add to the bike's sleek look, trustworthy 14-speed Shimano shifting with a wide range of gearing so you always have the right gear for your terrain, powerful mechanical disc brakes, and a suspension fork that takes the edge off bumps and rough terrain.

Marlin is made for any adventure. The rack and fender mounts make it a great choice for commuters who want to get a little rad on the way to class or the grocery store.

- Marlin Gen 2 is ready to roll with easy to use features that help you get the best bang for your buck
- Rack and fender mounts make it easy to accessorize, so your mountain bike can double as a rugged commuter
- 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
- 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
- Like every model in the Marlin family, it's backed by Trek's lifetime warranty
