Hasta La Ideas

A bunch of researchers at MIT has come up with an idea and prototype for a simple way to make just about any ordinary pushbike into an electrically powered one. Just change one (or both) of the wheels for a power-hub equipped one (above). The power hub contains everything except the (wireless) throttle; the researchers has managed to cram an electric generator, a battery and an electric motor inside a hub roughly the size of a smallish dinner plate. In it’s current configuration the GreenWheel has an estimated range of 25 miles, gives a top speed of 30 miles an hour, and an estimated life span of about 40,000 miles, or about eight years work of travel at an estimated 20 miles per business day. Clever, indeed. brbr
