As bike sharing becomes more and more popular in cities around the world, innovations in technology may make the systems a vital element of the urban landscape. Indeed, rather than simply a mobility tool, biking could become a power source — at least according to industrial designer Chi-Yu Chen, working at the Royal College of Art.
Mr. Chen’s bike design is innovative even as it uses standard technologies. By adding batteries to bikes and incorporating a dynamo in the wheel, the vehicles become mobile power stations, with electricity being created as commuters turn the wheels and apply power to the brakes. When cyclists return bikes to a station as part of a public rental scheme, the batteries would empty out their charge, moving the power into the general
