The key to the simple balancing act — lean forward to go faster, lean back to stop or reverse — is the advanced gadgetry inside the Onewheel. Built-in sensors and key-component algorithms work in conjunction with the direct drive hub motor. It’s powered by a 48v Lithium Nano-phosphate battery, and charging happens in as little as 20 minutes. While it doesn’t reach speeds of 88 mph, we think the 12 mph is still faster than walking.
