Trek E-Caliber 9.8 XT Electric Mountain Bike 2021 

Mirroring the looks of the non-electric Supercaliber model, the Trek E-Caliber 9.8 XT Electric Mountain Bike delivers sublime handling and the assistance needed to help you do more of the riding you love. Fast and lightweight, it retains a similar ride character to its non-electric sibling, yet provides natural feeling assistance to help you cruise climbs and flow across the flats. The system is removable, allowing the weight to be dropped by 2.9kg if assistance is not required, with an included cover allowing for internal downtube storage in its place.

With 55Nm of punchy torque, the Fazua Evation system packs the power needed for technical, singletrack climbs, helping to keep your legs fresher for longer. The 250Wh battery is slim, lending the frame an aesthetic that leaves other trail users double guessing your ride’s electric credentials, and a range of settings puts you in control of your assistance levels. The IsoStrut suspension is borrowed directly from the Supercaliber and provides 60mm of travel to enhance traction and vibration damping.

A dropper post adds versatility to this cross-country rocketship, and carbon Kovee Pro 30 wheels provide fast acceleration, thanks to their lightweight design and Rapid Drive 108 rear hub engagement. The 120mm RockShox SID Select+ fork stays composed in chattery terrain and compliments the FOX Performance internals of the IsoStrut system. A Shimano XT drivetrain adds proven 12-speed shifting performance, while the matching XT brakes add powerful, four-piston stopping power.


  • Shimano XT 12-speed 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
