Powerful engines used to be a thing of the car scene, the world of Subaru Impreza to Porsche Carrera, so to speak. Now there is more and more steam under the hood in the world of e-mountainbikes. Or at the bottom bracket. Bosch wants to be a major player in this segment and has come up with the CX-R motor. "R" stands for "Race". Such a mode is now also available for normal consumers instead of just Nathalie Schneitter.

The nominal values of the motor speak for themselves: 100 Newton meters of torque currently define the sporty setup. The previous high-flyer from DJI delivers a few points more. It also has 750 watts of maximum power. The Chinese model has 100 more. The CX-R delivers up to 400 percent of the pedal input by the rider. On the scales, it weighs in at 2.7 kilograms.

Even more sensors

The Bosch motors are known for their sensors. The CX motor with coupled ABS presented in fall 2024 sets the bar high here. The Race version goes one better with Dynamic Control, a type of traction control for very demanding terrain, steep passages or wet surfaces. Bosch says: "On challenging terrain, it's not just about power, the sensitive interplay of power and control is crucial. Dynamic Control is active on the CX-R in the new "eMTB+" mode.

The Race mode is intended for an aggressive, sporty riding style. It enables deceleration-free acceleration and supports you with full power up to top speed. When dynamically overcoming large boulders and complex root passages, the extended boost in Race mode provides additional thrust.

The Bosch CX-R brings the sports car genes to mountain biking. Vorsprung durch Technik, a slogan familiar from elsewhere. All that's missing now is the rear spoiler.
