The motor

Many Riese & Müller E-Bikes and Cargo Bikes are equipped with Bosch motors. The drives impress with absolutely no need for maintenance and are among the most reliable on the market. Effective pedal assistance reliably gets you to any destination.

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 (with the 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 sitting in the saddle. The button used to make your bike push itself at 6 km/h 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 up to a maximum speed of 32 km/h – or 45 km with our HS models. Combining the motors with a derailleur or Rohloff gear provides for greater efficiency than combining them with an Enviolo hub gear.

The following motors are used with the Bosch eBike system 2 and the smart system. Our specifications refer to the smart system. For information on the Bosch eBike system 2, please visit the Bosch eBike website.

The Bosch Performance Line CX motor

The Performance Line CX motor is a powerful and dynamic drive for intuitive handling and a unique riding experience – for even more riding enjoyment on technically demanding terrain. It stands apart with up to 340% pedal assistance, a maximum torque of 85 Nm, extremely sporty start-up characteristics, and pedalling rate assistance of up to 120 rpm. It stands out on account of its outstanding dynamics, minimal pedalling resistance and low weight of about 2.9 kg. At the same time, it is small and compact, ensuring ultra-aesthetic and unobtrusive integration.

The Bosch Performance Line Speed motor

Assistance up to a speed of 45 km/h makes the Performance Speed drive the fastest Bosch E-Bike motor. It impresses with its 250 watts of power, up to 340% pedal assistance, a maximum torque of 85 Nm, extremely sporty start-up characteristics, and pedalling rate assistance of up to 120 rpm.

For the Speed motor, you need an insurance certificate and a driving licence for small powered bikes. A driving licence for class AM (from the age of 16 upwards) or for cars includes this. Helmets are mandatory on HS models. We recommend using an E-Bike helmet that complies with the NTA 8776 standard.

The Bosch Cargo Line motor

The Bosch Cargo Line motor is the most powerful E-Bike motor Bosch has yet produced with programming optimised for Cargo Bikes. It currently represents the benchmark with up to 400% pedal assistance, a maximum torque of 85 Nm, extremely powerful start-up characteristics, and pedalling rate assistance of up to 120 rpm. Its excellent dynamics, very low pedalling resistance, weight of about 3 kg and compact dimensions cannot fail to impress, ensuring that it can be integrated ultra-aesthetically and unobtrusively.

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.
