Trek E-Caliber 9.6 Electric Mountain Bike 2021
Fast and smooth, the Trek E-Caliber 9.6 Electric Mountain Bike is a cross country weapon, packing an added boost for climbs in the form of a Fazua Evation motor system. Lightweight and low profile, this system is sleekly integrated into the frame, which uses the IsoStrut suspension first seen on the Supercaliber model. The motor and battery can be simply removed and replaced with a downtube cover, dropping 2.9kg from the bike’s weight if assisted riding isn’t required.
To add comfort on fast, flowing trails, the 60mm of suspension effectively damps vibration to reduce fatigue, without adding the weight of a complex linkage. The Fazua motor puts out 55Nm of power to offer natural, punchy assistance for climbs and flats, keeping your legs fresh for longer to enhance your riding experience. Light and slim, the 250Wh battery is housed neatly in the downtube, and power settings can be adjusted via the handlebar remote.
The high-value specification sees the epic XT 12-speed rear derailleur paired with a Deore cassette, chain and shifter. A selection of Bontrager in-house components complement the bike well, with the Kovee double-wall wheels offering extra strength and stiffness to improve power transfer. Four-piston Shimano brakes offer ample stopping power for the weight of the bike, and the RockShox 35 Gold RL fork features air adjustment to suit all riders.
