Technical Specifications

Torque & Power

Torque determines how powerfully your eBike accelerates. Bosch motors offer you a wide range. In the following table, you can see the most important values:

With up to 85 Nm of torque (Performance Line CX), you can master even steep climbs. Peak power reaches up to 600 watts, depending on the model.

Assistance Levels

You can choose between several assistance levels with Bosch eBike motors. The most important modes are Eco, Tour, Sport, Turbo, and special modes like eMTB or Sprint. The following table shows the differences:

Speed

Most Bosch motors support you up to 25 km/h. With the Performance Line Speed, you can reach up to 45 km/h. This makes it ideal for fast commuters.

Weight

Weight plays a major role in the riding feel. The Performance Line SX motor weighs only about 2 kilograms. The low weight is achieved through a magnesium housing and a compact design.

Sensors

The sensor technology in Bosch motors is highly precise. It measures 1,000 values per second. Sensors for force, cadence, and speed ensure that the motor always provides optimal support. A 32-bit processor controls the motor output with lightning speed. You feel the support immediately and in very finely dosed increments.

Batteries & Range

The range depends on many factors. Under optimal conditions, you can travel between 50 and 150 kilometers with a Bosch system. Factors such as your weight, the selected assistance mode, the terrain, and the weather influence the range. Bosch offers a Range Assistant that calculates these values individually. The batteries are powerful and long-lasting.
