Specification

It features a trail-savvy frame with a suspension fork, 9-speed Shimano CUES shifting and mounts for a rack and kickstand that make it an ideal choice for 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 aluminium frame with internal routing to protect your cables and add to the bike's sleek look, an upgraded 9-speed Shimano CUES drivetrain, a wide range of gearing so you always have the right gear for your terrain, powerful hydraulic disc brakes and a terrain-smoothing suspension fork with a lockout.

The final word:

The Marlin 5 is a great ride for all your adventures. It's also versatile and a popular ride on college campuses because the rack and kickstand mounts make it easy to accessorise and haul a load.
