What does power mean in the context of drive units?
Power is measured and indicated in watts (W). It is responsible for how fast you can ride: the higher the power, the higher the speed you can ride constantly. This is particularly noticeable when riding uphill, as eBikes have a legal speed limit of 25 km/h. To ride 25 km/h on the flat, < 250 W is usually sufficient (depending on the surface, bike/rider weight, wind conditions). For eBikes, we distinguish between rated continuous output and maximum power.
