The Impulse E Bike system was developed by the German company Derby Cycle AG. This system was a real innovation, because the Impulse E Bike mid-mounted engine was the first one that could be combined with a back pedal brake. Here you can find high quality tuning tools to derestrict Impulse electric bikes.
