Right on trend: the e-bike
There is a whirring sound in the air. A quick glance back over your shoulder and it's whirring past. The e-bike. All the rage and not always completely safe. We give you tips on what you should look out for when riding and show you which model is suitable for which application.
Things to know
Speed
Most e-bikes have pedal assistance of up to 25 kilometres per hour and therefore have a range of over 100 kilometres. Faster e-bikes reach a maximum speed of 45 kilometres per hour. Helmets are compulsory for these bikes and you must display a yellow licence plate with an insurance sticker on the e-bike. Controlling and correctly assessing these speeds is often a major challenge, especially for e-bike newbies.
Drive
E-bikes are usually powered by a centre or rear wheel motor. One advantage of the central drive is that both the pedalling cadence and the motor ratio are changed when shifting gears. Ideally, the rider and motor work at the speed that offers the best power delivery. In addition, the front and rear wheels can be easily fitted and removed as they are not equipped with a motor. Virtually all major manufacturers such as Bosch, Yamaha, Shimano and Panasonic rely on this technology.
Rear wheel motors are characterised by direct power transmission and good traction, which favours sporty and dynamic riding behaviour. The rider has the feeling that someone is pushing them from behind. Disadvantage: The wiring must be disconnected when changing the rear wheel.
Battery and range
The battery is one of the most important components on an e-bike. The major manufacturers generally use lithium-ion batteries. These are the measure of all things due to their comparatively low weight, high performance and environmental compatibility. The heavier nickel-metal hybrid batteries have become rarer and are now only used on affordable entry-level bikes.
The distance that can be travelled on one battery charge (range) depends on various factors: On the one hand, on the capacity of the battery itself and the strength of the selected motor support, but also on the terrain, tyre pressure, weight and the rider's own effort. Bosch, for example, has created an online range assistant that shows you how far you can get with your Bosch motor.

Range of use
City e-bikes are suitable for city commuting and daily journeys to work. For longer tours, a trekking model is ideal or a robust mountain e-bike for steep trails.
