Holger Hermanns crouches proudly beside his proof-of-concept wireless-braking bike. The wireless brake consists of a transmitting hand grip and a motorized disk-brake caliper. Squeeze the grip and the brakes are actuated according to a radio signal. Squeeze harder and you brake harder — as long as your batteries are charged. Just watch out for pranksters with RF transmitters who trigger your brakes from afar.
The Saarland team's work isn't intended to actually be used on bikes. Instead it is an experiment to see if wireless brakes can ever be made safe enough for use in trains, planes and automobiles.
