It's right for you if...

You're new to the trail and want a serious mountain bike that doubles as a commuter – and you want it all at exceptional value.

The tech you get

The Marlin 5 has 21 speeds and a wide range of gearing, which means that you never need to pedal too hard or easy on terrain that varies in elevation. It's equipped with hydraulic disc brakes that feel smoother than mechanical disc brakes and a 100 mm suspension fork with a lockout feature – that's the same amount of travel favoured by most cross-country racers.

The final word

The Marlin 5 is built according to Trek's MTB heritage, and is more than capable of taking on trail adventures. But it's also versatile. It's a popular ride on university campuses because the rack and mudguard mounts make it easy to accessorise and haul a load. The lockout feature on the fork lets you lock the suspension for the most efficient ride on smooth surfaces.
