The boffins at MIT are working on an all-in-one electric wheel hub called the GreenWheel which when retrofitted to old bicycles converts them to electric power. There are plenty of Chinese electric wheels on the market, but this one goes a stage further by folding all the technology, including batteries, into the single hub, making it easier to install and use.
