Pair of clockwork motorbikes
A pair of plastic toy motorbikes - one red, one black. Pull the rider's head back, 'scoot' him on the floor a few times to wind him up, then put his head down and let him whizz across the floor.

The stickers are a bit faded, but otherwise in good condition and both work, so you can have races :-)

13 cm (5 inches) long.
