At the heart of the bike is the Bosch Performance Line CX motor, delivering up to 85Nm of torque for powerful, responsive support that feels natural on the pedals. It’s paired with a massive 800Wh Bosch PowerTube battery, giving you the freedom to take on long rides without worrying about running out of range. The Bosch Purion 200 display is compact and easy to read, with intuitive controls to manage your assist levels while providing ride data at a glance.
Suspension is handled by the SR Suntour XCR 34 air fork, offering 120mm of travel to smooth out roots, rocks, and uneven ground. The fork includes a lockout for efficiency on climbs or smoother terrain, making it adaptable to a wide range of conditions.
Shifting duties are taken care of by the Shimano CUES U6000 10-speed drivetrain, designed with LINKGLIDE technology for long-lasting, smooth gear changes. Combined with an 11-48T cassette and 36T chainring, this setup offers plenty of range for both climbing and descending. Stopping power comes from Tektro HD-M275 hydraulic disc brakes, giving reliable control in all conditions.
The bike rolls on 29” Bontrager Connection double-wall wheels, fitted with durable tyres designed for grip and stability on a wide variety of terrain. A 780mm alloy handlebar offers control and confidence on the trails, while a Bontrager alloy seatpost and Commuter Comp saddle provide lasting comfort.
