What does the specification of the power-to-weight ratio for the drive units mean?

The power-to-weight ratio indicates the ratio of the maximum power to the drive unit weight. It indicates the maximum power provided per kilogram and serves as a comparative value between different drive units. A higher power-to-weight ratio can lead to a higher speed, as weight plays a role for this. Weight is a significant component of riding resistance, which means that a higher final speed can be achieved with the same power and a lower weight. eBikers notice this primarily on steep climbs and on mountains, as weight plays an increasingly significant role in riding resistance with increasing gradient. However, the total weight (eBike and rider) should always be considered.
