The genesis of the Ryno one-wheeled electric motorcycle can be traced back to a moment when Chris Hoffman’s daughter asked if he could build something like what she saw in an episode of Dragon ...

The cost for a pre-production Ryno is a whopping $25,000 and Hoffmann already has five orders, but he expects the market model to cost about $3,500.

It's called the Ryno, an all-electric single-wheeled scooter that looks like something Judge Dredd would throw a leg over before bringing justice to some nefarious evil-doers.

The RYNO isn't all that difficult to ride; a 10-15 minute lesson should suffice. It's meant for moving around a warehouse or mingling with pedestrians, so 10 mph is "plenty fast," Hoffman said.
