While you're waiting, there's this:

Yes it's Blue Peter, but it's not all about cars. There's a bit at 07:34 where the three presenters design their own bicycles and present the designs (briefly) to a panel consisting of Mr Obree amongst others. Then they race them...
Given that the presenters 'design their own', two of the designs seem quite familiar. If you are wealthy enough, I am sure Laidback Bikes could provide them (although probably better-finished than the Blue Peter versions). One of the designs is rubbish.
In case you're wondering, Mini-Greenroofer likes Blue Peter. It's not something I tend to watch on my own any more.
