  • Features

    • SmartForm C2 alloy construction with high-performance tube shapes, weight-saving butting and seamless double-pass welds delivers a frame that is light, durable and lively
    • Durable, reliable Bosch Performance Line Sport 250W drive unit and 500 Wh battery give pedal assist up to 28 mph with the juice to go the distance—up to 104 mi.
    • Proprietary motor mount positions the Bosch drive unit low and forward in the frame, keeping the center of gravity low and the chainstays short for agile handling
    • SR Suntour XCM ATB fork offers 100 mm of bump-absorbing travel; SAVE micro-suspension in the frame absorbs vibration and shock for improved control and comfort
    • 9-speed drivetrain and hydraulic disc brakes deliver reliable performance in any conditions
    • Secure, rattle-free fenders, a full rear rack, bright front and rear lights, and even a kickstand mean you're ready to tackle any adventure
    • All the features that make it so capable off-road translate into a comfortable, confident experience on-road, so you don't have to worry about potholes, gravel or tram tracks
    • Integrated wheel sensor helps track your activity (speed, distance and calories burned), registers your bike and reminds you of needed service via the free Cannondale app
    • Highly reflective accents on the frame and fork increase visibility in low light
    • Specs and images are subject to change
