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 versatile ride an excellent entry point 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. Disc brakes, knobby tyres and 21 speeds make Marlin 4 a great choice.
The tech you get
Marlin 4 has 21 speeds with a wide range of gearing for easy riding on varied terrain. It's modelled on our higher-end mountain bikes and built with a lightweight Alpha Silver Aluminium frame, mechanical disc brakes for increased stopping power in any weather conditions, and a suspension fork with 75 mm of travel – just enough to absorb the big bumps and keep you cruising.
The final word
Marlin 4's greatest gift is its versatility. It's built according to Trek's mountain bike heritage and is totally capable of taking on the trails. But it's an efficient daily rider, too. 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.
Why you'll love it
- It's a real mountain bike that's also perfectly suited to daily commutes, rides around campus or just getting from A to B on any surface
- The flat mountain-style handlebar and disc brakes keep you in control, on or off the trail
- Rack and mudguard mounts make it easy to accessorise, so your mountain bike can double as a rugged commuter
- Like every Trek, it's backed by a lifetime warranty
