Welcome Shay Carl fans, this is how we modded Shay's Bike! You can harness your heavy pedaling and generate some juice for your cell phone. With this nifty bike mod you can ride around all day and never worry about your phone dying on you.
All you need is a cheap hand crank radio or flash light that has a USB port. We will strip it down a bit and connect it to our bike tire for optimal charging power!
