Benchwheel Penny Electric Skateboard

The Benchwheel Penny Board is a 28-in / 71cm single motor electric skateboard. It's what you would call a Chinese electric skateboard. The appeal is to make a battery powered Penny Board (the plastic boards), actually this is the size of the Nickel board and made of wood instead of plastic.

The approx. range is 10km / 6 miles with a max. speed of 24kph / 15mph, but expect less if you don't upgrade to better quality parts yourself.
