New: the best drive partners of all time


The Impulse 2.0 shift-sensor technology and the Gates carbon belt are the ideal drive partners for maximum comfort, unalloyed riding pleasure, maintenance-free cleanliness and a long service life: no rust, no dirt, no squeaks, simply trouble-free.

The enhanced high-tech toothed belt has been specially adapted to suit the requirements of Kalkhoff, while the  motor system is equipped with shift-sensor technology for smooth shifting even under load. Together they achieve optimal performance and a completely new quality of ride. In addition to a considerably softer and more direct feel while you pedal, the toothed belt offers important advantages in handling and wear. The carbon belt is maintenance-free, which means no re-tensioning, especially after the bicycle has been run in. Nor do you have the bother of cleaning or oiling. Furthermore, it is a lot more durable, and you don't have to worry about getting oil on your clothes.




Impulse 2.0 Shirft Sensor – leichter Schalten

World-first shift-sensor technology

We invented the perfect gear-change: faster, quieter and low-wear, even with pressure on the pedals.Perfectly integrated in the overall system, the shift-sensor technology interrupts the power flow for fractions of a second with each gear-shift. Imperceptible for the rider, individually adjustable, for both hub gears and derailleur gears.
