Trek E-Caliber 9.9 XTR - 252Wh

£

The 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.

You want to 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, most precise parts spec, filled with carbon and cutting-edge tech like our IsoStrut shock.

A lightweight, full OCLV Mountain Carbon frame with 60 mm of travel, a 120 mm FOX Factory 34 fork, dual remote lockout and Trek's exclusive lightweight IsoStrut FOX Factory shock. A new Fazua Ride Trail 50 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, plus a handlebar-mounted Fazua Ride Remote FX controller. A Shimano XTR 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.
- 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
- 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 provide better tire support so you can run lower pressure and get more traction

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.

OCLV Mountain Carbon
Trek's mountain-specific carbon fibre is tougher carbon, with unique materials and lay-up procedures, Trek's advanced engineering, and a higher standard of testing.
