Description
Choose the road less travelled, and see where you end up. The CUBE Reaction Hybrid Performance Electric Mountain Bike is built around Bosch's quiet, powerful Performance Line motor with 75Nm torque. It is Bosch Smart System-equipped and is paired with a Bosch PowerTube 625Wh battery for worry-free longer rides.
Easy-to-use Shimano 9-speed gears and powerful Shimano hydraulic disc brakes give you smooth shifting and reliable stopping power in all weathe, and a 100mm travel SR Suntour suspension fork, ACID PP MTB saddle and lock-on grips ensure you're comfortable for the long haul. Rolling on Rodi Blackrock 23 tubeless-ready wheels fitted with Schwalbe Smart Sam 2.35" tyres, exceptional traction and good puncture protection are guaranteed. The smallest sizes (XS and S) use 27.5" wheels and the larger ones 29" wheels for optimised ride feel and performance across the entire range.
