Inventor reveals one-ball successor to viral bike

An inventor who created a bike with two large red balls instead of wheels has revealed his latest creation - a bike with just one ball.

James Bruton, whose gadgets have been viewed millions of times on YouTube, said: "There are a few extra challenges, like how to turn to steer, and also making omni-wheels strong enough."

The robotics expert who builds all of his inventions in a secret location in Hampshire, used to work in IT and was a toy maker before switching to being a "full-time internet creator".

The balls on his battery-powered bike are the same type as used by circus acrobats and are self-balancing.

A video of Bruton's "omnidirectional one-ball bike" has been viewed almost 900,000 times on YouTube and featured on the BBC Tech Now.
