It's a particular kind of bicycle. It finds the right balance by itself, even if you wobble. It is almost impossible to fall.

The "Jyrobike" contains a patented control hub in the front wheel that uses gyroscopic technology to keep riders upright, even when they tip or wobble. It is aimed at 3-8 years old when they are learning to cycle. Their engineers say it can teach you to cycle in an afternoon, without the usual associated risks.

Jirobike has been developed by a cycling enthusiasts that launched a campaign on crowd-funding site Kickstarter, to try and take the project beyond prototype stage.
