E-Caliber 9.8 GX AXS is a lightweight carbon electric mountain bike that rides - and looks - like a traditional cross-country bike. It's built with the same race-worthy tech as Supercaliber, including our exclusive IsoStrut integrated shock, and it has a sleek Fazua drive system that delivers a little boost when you want it most. You also get a GX Eagle AXS wireless electronic drivetrain for blazing fast shifts.

You're an avid XC rider, and love the idea of an e-MTB that helps you push your limits without providing too much assistance. It's also great for those who want to get out and ride more, or keep pace with faster friends.

A lightweight OCLV Mountain Carbon frame with 60 mm of travel, a 120 mm RockShox SID Select+ fork and Trek IsoStrut shock. A new Fazua Ride Trail 50 motor and 250 Wh battery that can assist up to 20 mph (25 km/h in Europe) when it's on, and gives zero drag when it's off. A SRAM GX Eagle AXS wireless electronic drivetrain, Bontrager Line Elite dropper post and wider Kovee Pro 30 carbon wheels with a 108-tooth Rapid Drive rear hub for instant engagement.

The E-Caliber flies down singletrack like an XC MTB - because it's modelled on Supercaliber! The Fazua drive system provides just the right amount of assist, and SRAM's newest wireless electronic drivetrain ensures that every shift is crisp and ultra-fast.
- 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 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
- The SRAM GX Eagle AXS drivetrain is smart, smooth and completely wireless
- 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 customise your ride.

Smart software for the trail
The 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 customise your user settings.

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

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