The Trek Marlin 4 is a trail-worthy daily rider that's perfectly suited for everyday adventures, on and off the trail. A suspension fork, 14 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.
The Marlin 4 features a lightweight aluminium frame with internal shift cable and brake hose routing to protect your cables and add to the bike's sleek look and a suspension fork that takes the edge off bumps and rough terrain. The 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 and a curved top tube and a lower standover height that makes it easier for smaller riders to mount and dismount, so you get a bike perfectly moulded to your size.

This versatile hardtail delivers a great ride for all your adventures, but also doubles perfectly as a commuter bike so you can get the best of both worlds!
