Trek Marlin 4 Gen 2 Alpine Blue

Size

See our bike sizes guide HERE

Marlin 4 is the perfect gateway to trail riding. It's ideal for new riders who want a mountain bike with knobby tyres, that can double as a rugged commuter. Disc brakes, front suspension, 21 speeds and mounts for a rack and mudguards make this a great bike for new trail riders and campus commuters alike.

It's right for you if...

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

The tech you get:

A lightweight aluminium 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, powerful mechanical disc brakes and a suspension fork that takes the edge off bumps and rough terrain.

The final word:

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