The bike that 'teaches you to ride'

A team of engineers have developed a bike that balances by itself, which they say could allow people to learn how to ride a bike in an afternoon.

The bike, aimed at 3-8 year olds, has a special front wheel that uses gyroscopic technology to keep riders upright, even if they lose their balance.

The inventors - a group of cycling fanatics - have started a Kickstarter campaign on the internet to get more funding to develop the bike.

Martin's been looking into how it works.
