Solar Powered Bike

Here’s a quick video of my electric bike and solar panel kit that charges it. The bike has a 200w motor and a 13ah battery. The bike is power assist, so the motor kicks in when you are pedaling and it makes going up hills a breeze, although you still have to work. The solar panel system that charges the bike is 3 x 80w panels on the roof, down to 20A regulator and 4 x 130ah deep cycle batteries up to a 600w pure sine inverter. The bike draws around 50 amps when charging the battery, and a full charge takes around 4 to 5 hours or so. The solar setup is of course overkill for charging an electric bike, but I use the solar power for other things too. Eventually I’d like to build the solar kit to charge an electric car, when that time comes. My goal was to have a zero emissions mode of powered transport, and this is what has been achieved with the solar powered bike. 🙂
