Description  > The BÜCHEL Edge rear light with integrated Z-reflector, the first sensor-controlled brake light, optionally with emergency braking indicator, for bicycles in accordance with the new StVZO and ECE directive, offers a major safety boost for cyclists.  > The STOPTECH brake light function is a joint development with the Fraunhofer Institute in Dresden. The sensor technology, which detects the deceleration of the speed during the braking process, makes a connection to the braking system via cable superfluous. The ECE directive states that the minimum value of the brake light must be 40 candela, which is several times brighter than the short-term signalling previously permitted in the StVZO. The brightness of the Edge brake light with 45 candela is more than five times that of the tail light. In the event of heavy emergency braking, all LEDs flash to clearly warn traffic behind. This considerably increases safety in road traffic.   Many current bicycle models, whether with or without electric assistance, have a rather angular design. BÜCHEL has picked up on this with the Edge LED rear light, which is equipped with quality LEDs from Osram. The light is mounted on the luggage carrier (mounting width 50 or 80 mm) and integrates seamlessly into the visual appearance of modern bicycles.
