A new level of riding comfort and safety
Brightly lit curves for a comfortable and safe riding experience. During steering movements, the Leval always keeps the light-dark boundary at the same height. This means that the light field does not tilt to the lower left or right when the bike is tilted and the headlight range reduction previously associated with this is prevented.

The Leval is installed between the holder and the headlamp. No adjustment is necessary. Simply switch it on and off you go. The curve light assistant is suitable for all e-bike headlights from Busch + Müller with the exception of the IQ-XL highbeam. Approved by the German federal office for motor vehicles
