Any ideas of how to get a USB power socket on a 36v electric bicycle? How about gutting an iPod/iPhone charger and just connecting the 36v across the mains live and neutral pins? Over-driving a 12v car cigarette lighter adapter? Tapping into the throttle 5v +ve feed?
One of my favourite Stages/Tents/Tea rooms at Glastonbury is entirely powered by a stationary cycle and solar. And they have a deal, cycle for 5 minutes get a free cup of tea.
You're right in a way. If there's a plug to charge the bike, it can charge the other devices at the same time.
