You're just getting started on the trails and looking for a genuine mountain bike that can also handle commuting. All at a great price.
- The Marlin Gen 3 handles trails with ease. It has plenty of tire clearance and comfortable geometry for confident, stable riding from singletrack to city streets.
- Fender mounts make it easy to add accessories that turn your mountain bike into a commuter machine.
- The ThruSkew system is safer, simpler, and stronger, and makes it easier to remove the rear wheel for quick flat repairs.
- Internal cable routing makes it easy to install a dropper seatpost, which allows you to lower the seat while riding for more confident descents.
- Marlin models in sizes XXS and XS feature a sloping top tube that is also lower to the ground. This makes it easier for smaller riders to get on and off.
The Marlin 5 is a great bike for any adventure. It's a versatile machine popular with students thanks to its rack and kickstand mounts, which make it easy to add accessories and carry cargo.

TREK is headquartered in Waterloo, Wisconsin. The family-owned business was founded by Richard Burke in 1976, starting out in a small steel bicycle factory with just five employees. Within a few short years, the company caught on to bicycle trends and continued to grow. In the early 1990s, it began producing bicycles in a then-new material - Carbone. Today, TREK sets the trends in bicycle development and is also considered a leader in the processing of Carbone. Its proprietary processing technology, called OCLV, has been applied in production with many innovations for more than 17 years. TREK bikes have celebrated success at major world races and have been associated with names such as Lance Armstrong, Alberto Contador, Chris Lieto, Roland Green, Chris Eatough, Andrew Shandro and Travis Brown. TREK is a premium brand you can always rely on.
