Features
Bosch Performance CX
Bosch’s Performance CX line is made for rugged off-road use with a maximum torque of up to 75 newton metres, sustained power into the high cadence range for sporty acceleration and a sleek mid-mount motor for ideal weight balance and obstacle clearance.
Bosch Purion Display
Bosch's Purion display features a fully-functional speedometer with a backlit display, service interval indicator and battery range indicator. Its thoughtful design allows riders to scroll through functions or choose the right level of support while maintaining contact with the handlebars.
Motor Armor
This unique protection shield is lightweight yet robust, and protects the motor from rocks, logs and other trail debris.
Lighting ready
The bike is already internally wired to accept additional lights. Go to your dealer and simply have them attached to the bike and plug them in.
Rack mounts
Going for a long ride? Rack mounts make carrying accessories a breeze.
Smart Wheel Size
The right wheel size paired with your frame size gives you the perfect combination of responsiveness and control.
Alpha Platinum Aluminium
Our premium lightweight aluminium is continuously cold extruded and butted at multiple points, and hydroformed into sophisticated tube shapes for maximum strength and minimum weight.
Boost148/110
Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 at the back lets you run wider tyres and a larger chain ring without affecting q-factor and pedalling efficiency.
