Kalkhoff Impulse. Drive system with centre motor and backpedal brake or freewheel. Our Impulse drive system combines the balanced ride characteristics of a centred and deep-set drive with the usual assistance of a back-pedal brake and two hand brakes. Here, the motor impresses with its superbly controlled performance: soft, controlled startup followed by an increase in power. So you benefit from the full motor output even when climbing a hill. And that means even more riding fun. SPEED SENSOR ON REAR WHEEL
In addition to a torque sensor, the Impulse drive is also controlled by a speed sensor. This means that the maximum power assistance will also be provided when riding with higher pedalling cadences at lower speeds, when cycling uphill for example.
IMPULSE MOTOR
range
A torque sensor is integrated into the motor unit. The assistance provided by the brushless motor increases as the pedalling effort increases – up to a top speed of 25 km/h.
Under optimum conditions and with a fully charged battery in top condition, you can cover a distance of up to 205 km with a Kalkhoff Impulse. The range is dependent on factors such as assistance, speed, temperature, the number of start-ups, the gear selected and the hills to be climbed.
