Professor Holger Hermanns with his prototype wireless bicycle braking system.
Wireless gear-shifting for bicycles has been around for the past few years. Now someone has developed a wireless braking system. Created by computer scientists at Germany’s Saarland University, the current prototype still looks a little boxy, but it does do away with cables and brake levers. According to computer algorithms that would normally be used in control systems for aircraft or chemical factories, the system should offer 99.999999999997 percent reliability – that means it would fail three times out of a trillion braking attempts.
