Focus Designs has a new version of their self-balancing unicycle for sale. This improves upon their original design in several ways. The battery pack has moved to LiFePO4, which is becoming more common in electric transportation. There’s also regenerative braking and fall protection which kills the motor when you fall off. You’re at about 10 mph in a couple seconds without even thinking about it. There is no clutch pedal to contend with and no race-car driving techniques to perform.
