It's right for you if...
This bike is perfect for XC riders who want to push a little farther or a little steeper. It's also great for anyone who needs a little boost to motivate them to ride more, to get up climbs, or to keep pace with faster groups.
The tech you get
An OCLV Mountain Carbon frame with 60mm of travel, a 120mm RockShox Gold RL fork, and Trek's IsoStrut FOX Performance shock. A Fazua Ride Trail 50 drive system that can assist up to 20 mph when it's on, and gives zero drag when it's off, plus a Shimano Deore 12-speed drivetrain, dropper post for getting low on descents, and Bontrager Kovee Comp 23 wheels.
The final word
E-Caliber is a fast and smooth XC bike that just happens to have a compact drive system that'll give you a little boost when you want it.
favorite_borderWhy 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

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.
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.
Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 in the rear lets you run wider tires and a larger chainring without affecting q-factor and pedaling efficiency.

Sizing & Tech
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
