Reaction Hybrid 2023

The 2023 Cube Reaction Hybrid is the brand's mainstream aluminium hardtail eMTB, built on the 85Nm fourth-generation Bosch Performance Line CX motor with the Smart System electronics and a removable Bosch PowerTube battery. It is a do-everything trail and fitness hardtail rather than a technical descender, with a 120mm fork, a 67 to 68 degree head angle and a 74 to 75 degree seat angle. Size S runs 27.5in wheels under Cube's SizeSplit while M to XXL move to 29in, and the chainstays are a long 460mm on the 29er sizes, so the fit is stable and roll-happy.

The four UK builds we read climb in a clear ladder. The Pro 625 at £2,799 pairs a 625Wh battery, an X-Fusion MIG32 fork and Shimano Deore 11-speed with basic BR-MT200 brakes on 180mm rotors. The Pro 750 at £2,999 is the same bike with the larger 750Wh battery for extra range. The Race 750 at £3,499 is the keen rider's pick, stepping up to a RockShox Judy Silver fork, Shimano XT 12-speed, four-piston BR-MT420 brakes on 203mm rotors and Cube EX30 rims. The flagship SLT 750 at £3,999 adds a Fox 34 Float fork, Shimano XT four-piston brakes and shifters, and Newmen Performance 30 wheels.

This model year has been discontinued. Cube later moved the Reaction Hybrid range onto larger 800Wh batteries and refreshed naming for the following years, so the 2023 625Wh and 750Wh builds are an earlier generation of the same Bosch CX hardtail platform.
