E-Caliber 9.9 XTR is a light, fun, and fast carbon e-MTB. It's built to ride like a traditional cross country bike, and it even has the same race-worthy suspension tech as Supercaliber. The sleek and subtle Fazua drive system provides a boost without adding bulk, and you get a spec loaded with high-end parts.
It's right for you if...
You wanna ride your heart out on a lightweight e-MTB that rips singletrack just like a regular XC bike, but can give you a leg-saving boost when you want it. You also want the smoothest, lightest, more precise parts spec, filled with carbon and cutting edge tech like our IsoStrut shock.
The tech you get
A lightweight, full OCLV Mountain Carbon frame with 60mm of travel, a 120mm FOX Factory 34 Step-Cast fork, dual remote lockout, and Trek's exclusive lightweight IsoStrut FOX Factory shock. A Fazua Evation motor and 250Wh battery that can assist up to 20 mph when it's on, and gives zero drag when it's off, plus a handlebar-mounted Fazua Remote FX controller. A Shimano XTR drivetrain, a Bontrager XXX carbon seatpost, and Kovee XXX 30 carbon wheels.
The final word
Our top-shelf E-Caliber is light, fast, and built to rip. It rides like an XC race bike—like a Supercaliber, in fact—until you decide you want a little boost to scramble up a climb or put in a few extra laps.
Why you'll love it
- 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 analog bike than a typical e-MTB
- The 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 2.9kg less than before
- IsoStrut gives you just enough rear suspension for cross country traction and comfort with less weight and more efficiency
- Pivotless seat stays save on weight and actively bend to help soak up trail chatter
- Wider Kovee XXX 30 wheels are crazy light, really strong, and provide better tire support so you can run lower pressure and get more traction
