Was the pic from the Gadget Show the other week?
It was called Ryno or something...

No, the picture is a similar vehicle called the Uno. It is a transforming 3 wheeled motorbike which can self balance on the back wheel (two wheels now due to stability issues when extending the front wheel when there was only one wheel on the back).
That Ryno one looks interesting too.
