Trek E-Caliber 9.8 GX Electric Mountain Bike 2021

Developed to extend your cross-country rides, the Trek E-Caliber 9.8 GX Electric Mountain Bike combines the World Cup proven Supercaliber platform with the minimalist Fazua Evation motor system, providing natural feeling assistance and supreme handling. Lightweight and agile, this frame reigns supreme amongst its peers, and to further reduce the weight the system can be removed when assistance is not required, dropping 2.9kg in the process.

Although low-profile in its design, the Fazua system packs 55Nm of hill-climbing power into its minimal footprint, helping you to breeze technical climbing sections and keep your legs feeling fresh. The 250Wh battery is slim in its design and is integrated neatly into the frame for a clean aesthetic. 60mm of IsoStrut suspension boosts comfort and traction on rough terrain and utilises pivotless seat stays, eliminating the need for a complex linkage. 

A well-rounded parts specification ensures epic performance on the trail and includes a full SRAM GX 12-speed drivetrain and G2 four-piston brakes, for slick shifting and phenomenal stopping power in equal measure. Kovee carbon wheels reduce rotational weight for fast acceleration, and the rear features the Rapid Drive 108 engagement hub for near-instantaneous acceleration. 


  • SRAM GX 12-speed drivetrain for smooth, precise shifting
  • You get a helping hand from the motor on climbs and long rides, but it's a more natural-feeling assist that gives you an overall experience that's closer to riding an analogue bike than a typical e-MTB
  • The Fazua drive system, including the motor, is easily removable. Just take it out, pop on the included cover, and you’ll have a standard mountain bike that weighs 2.9 kg less than before
  • IsoStrut gives you just enough rear suspension for cross-country traction and comfort with less weight and more efficiency
  • The pivotless seat stays save on weight and actively bend to help soak up trail chatter
  • BLACK PEPPER firmware update enhances the performance of the bike
  • OCLV mainframe, with IsoStrut suspension, Control Freak internal routing and Knock Block
  • Lightweight Bontrager Kovee carbon wheelset improves climbing and handling
  • Fast-rolling 29” wheels for ultimate cross country performance
