Kalkhoff Launches e-Bike with Coaster Brake

CLOPPENBURG, Germany – Derby Cycle AG, ‘mother’ of, among others, the Kalkhoff and Focus brand names developed an e-bike with a very specific German feature. The new e-bike offers a combination of a bracket motor with a coaster brake. Derby Cycle calls this its ‘Impulse’ system which according to the bike manufacturer, makes: “The transition from a ‘standard’ bike to an e-bike a lot easier and safer for the consumer.”

“Until now, consumers could only choose between compromises such as a bracket motor with only hand brakes or a combination of a coaster with the technically inferior option of the engine in the front hub”, said Mathias Seidler, CEO of Derby Cycle AG at the presentation of the Impulse models last Thursday in Berlin. “The Impulse system allows a bracket motor and a coaster brake, even in combination with hand brakes.”

The Impulse system is an important addition to the market as the German law requires two independent operating brakes on a bike. Many starters on e-bikes, especially older people, who were used to a coaster in combination with hand brakes, don’t feel safe and comfortable with hand brakes only. The Impulse makes it possible again to have the same brake configuration as they were used to. Next to Germany also in the Netherlands, Denmark and Sweden consumers are used to bikes equipped with coaster brakes.  

The advanced technology of the Impulse system provides permanent calibration of the engine and retrieves its information for the required pedal assist force from three different sensors. This system responds without delay once the rider puts force on the pedals. Derby Cycle claims a maximum range of 100 kilometers but emphasizes that it depends on many external factors such as the weight of the rider, the outside temperature, wind etc.

Derby Cycle focused strongly on the design of the Impulse bikes. Result is that the battery has been neatly integrated and is hardly noticeable. The Kalkhoff and Raleigh branded Impulse e-bikes are available from late April.
