This is the Enicycle, a Segway-like unicycle built by Aleksander Polutnik, a guy who couldn’t ride a real unicycle. There is some good design here, like the steering mechanism of leaning to pivot the wheel and shocks to keep the ride smooth, but I’m skeptical about the unicycle-like stance. That stance half way between standing and kneeling hardly seems natural. Here it is in action:
I’ve had the pleasure of racing on an off-road Segway, and I think they are a great concept with plenty of room left for innovation.
