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.
