A small generator, with electronic power regulation, charges a battery pack that has a USB port as you cycle. The generator fits in between the rear wheel and the bike frame and is easily fitted to bikes with quick-release wheels. A USB cable can be used to charge your electronic device while also charging the battery pack at the same time.
How does it work?
The revolutions of the rear wheel, caused when on a commute or longer weekend cycle rides, power a generator that provides charge to a separate battery pack. This battery pack has a USB port that allows you to plug in and charge your smart phone, camera or other electrical gadget on the go. Otherwise you can use the battery pack to charge your phone after you stop as the charge will remain.

Still in process, this product is certainly one to look out for as the potential positives are numerous.
