Kalkhoff is the largest e-bike manufacturer in Germany by numbers. They have been in the business of building bikes for nearly a century and have developed their own e-bike drive unit, the powerful Impulse system featuring a big battery. Kalkhoff bikes generally provide good value for money and are all designed for urban use, with all the essentials like mudguards, racks and lights standard. Most models come in different frame shapes and a large number of sizes. The Entice Advance B10 is a new model for 2018 featuring Shimano Deore 10-speed derailleur gears and hydraulic disc brakes as well as a large capacity battery for long-range rides.
