2022 Trek Bicycle E-Caliber 9.9 XX1 AXS S

E-Caliber 9.9 XX1 AXS 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.

You wanna ride your heart out on a lightweight e-MTB that rips singletrack just like a regular XC bike, but can give you an unobtrusive boost when you want one. You also want an amazing parts spec, filled with carbon and cutting edge tech like a fully wireless electronic drivetrain and our IsoStrut shock.

A lightweight, full OCLV Mountain Carbon frame with 60mm of travel, a 120mm RockShox SID Ultimate fork with Charger Race Day damper, remote lockout, and Trek's exclusive lightweight IsoStrut FOX Factory shock. A Fazua Ride Trail 50 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 Ride Remote FX controller. A SRAM XX1 Eagle AXS wireless electronic drivetrain, a FOX Transfer SL dropper, and Kovee XXX 30 carbon wheels.

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.

• The SRAM XX1 Eagle AXS drivetrain is smart, smooth, and completely wireless

• 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

Features may include:

• Fast and efficient

Fazua's lightweight drive system adds a punch of power when you need it, but rides and feels like a traditional bike when you don't. You won't feel much drag or resistance when you turn it off or pass the max level of assist. The system is also compatible with a smartphone app to let you check battery status and customize your ride.

• Smart software for the trail

E-Caliber is equipped with intelligent Fazua software called BLACK PEPPER, which allows the motor to respond immediately as you start to pedal, delivers more power over a wider cadence range, and lets you customize your user settings.

• Removable drivepack

Remove the motor and drivepack to save 6.4 lbs./2.9 kg on days when you don't need the boost. The included cover also turns the down tube into extra storage.

• IsoStrut

E-Caliber has the same innovative IsoStrut rear suspension as World Cup-winning Supercaliber. You get 60mm of integrated rear travel—just the right amount of comfort and traction, without the weight or flex of traditional full suspension.
