The motor.

All Riese & Müller E-Bikes and E-Cargo bikes are equipped with Bosch motors from the Performance line. The drives impress with absolute freedom from maintenance and are among the most reliable on the market. With pedal assistance of up to 20 mph (32 km/h), and up to 28 mph (45 km/h) on our HS models, you can reach any destination effortlessly.

With the tremendous driving force of the Bosch motors, you can conquer any terrain and any mountain. Its aesthetically pleasing integration into the crank bearing ensures plenty of ground clearance, a low centre of gravity, directional stability and the direct transfer of force to the back wheel via a chain or belt. The riding experience provided by the mid-mounted motor most closely approximates the sensation of riding a normal bike. All Riese & Müller E-Bikes are Pedelecs and S-Pedelecs (HS models). The driving force is controlled using the pedals, not via an accelerator handle as on a motorbike. The harder you push on the pedals, the more the electric drive supports you. When you stop pedalling, the motor stops and you continue to roll – just like on any normal bike.


A pushing and starting aid fitted as standard helps your E-Bike up slopes even when you’re not in the saddle. The button used to make your bike push itself at up to 6 km/h (or 15 km/h on the HS models) is located on the external control unit. The maintenance-free motors have an electronic control unit with an ultra-modern 32-bit processor and sensors for power, pedal rate and speed. Thanks to 1,000 sensor measurements per second, its coordination is superb. The higher the power, the higher the torque and therefore the faster the acceleration. The maximum speed up to which your motor provides assistance is 20 mph (32 km/h). The Performance Speed motor of our HS models provides assistance up to 28 mph (45 km/h). The combination of the motors with a derailleur gear enables a greater degree of efficiency than the combination with a hub gear.

Bosch Performance CX motor

The highest-torque Bosch drive guarantees maximum riding fun – even up hills. Its enormous performance, coupled with sensitive responsiveness, produces a completely new riding experience off the beaten track. The maximum torque is 75 Nm, with pedal assistance of as much as 300 % – even at high speeds. The new eMTB mode means you no longer have to choose between various levels of assistance, because the progressive motor assistance automatically adapts to the riding style regardless of the pedal pressure. You can notice a huge difference especially on hills: this is Uphill Flow. (The eMTB mode replaces the Sport mode. It is shown on the Intuvia display as Sport mode.) With "Direct Flow" you have powerful thrust on the rear wheel from 20 rpm already. Whether it be uphill or on the flat, this acceleration will inspire you.

Bosch Performance Speed motor

Assistance up to a speed of 20 mph (32 km/h) makes the Performance Speed drive the fastest Bosch E-Bike motor. Sporty start-up characteristics, 350 watt power and pedal assistance up to 275% guarantee the ultimate riding pleasure with a maximum drive torque of up to 63 Nm with derailleur gear and up to 50 Nm with hub gear (excluding Rohloff).

The Bosch range calculator.

Calculate the range of your next E-Bike tour in advance online. You can enter parameters such as the rider’s weight, motor, battery or type of terrain. You can also influence the range independently of your E-Bike's technology. Reduced pedal assistance and more muscle power on your part can increase the range significantly.
