Rail+ 9.8 is a carbon enduro mountain bike for climbing remote peaks and tackling circuits. With 160mm of travel front and rear, it handles rough terrain with ease. Supported by a powerful Bosch Performance CX drivetrain, you'll find long climbs and fast circuits a breeze. It has adjustable geometry that allows you to tailor the bike to the way and place you ride, a large capacity battery for tackling circuit after circuit, and SRAM GX AXS wireless gearing for precise shifting under load.
You're taking on challenging rides in even more challenging terrain, and you need an e-bike that can keep up. You want enough suspension to tackle roots and rocks, and a motor with maximum support that won't let you down on the climbs. You care about upgrades where they matter most, like a carbon frame, upgraded suspension, and a completely SRAM wireless shifting system.
- With enough travel and power, the Rail+ will give you a great ride from peak to peak or endless enduro circuits.
- Better components are right where it counts. These include SRAM shifting and RockShox suspension.
- Geometry and leverage ratio can be adjusted to suit the way you ride. Further adjustments are achieved by using special cups (sold separately) to adjust the head angle.
- The powerful Bosch Performance CX system will take you up steep climbs at full throttle for a relaxing descent.
- The large-capacity 800Wh RIB 2.0 battery offers support for longer rides and can be easily removed for transport or storage.
The Rail+ 9.8 bike is ready for epic rides into unexplored places. With big travel for tough terrain, a powerful motor for tackling big climbs, and a high-capacity battery that lasts for the long haul, this bike can do it all.

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.
