I told you not to leave your bike out in the rain!!

Very cool.

Its belt driven.

dude said: "These bikes need no maintenance and no adjustment, a car timing belt is used instead of a chain, and the tyres do not need inflating and can last for 10 years," he said.

I like the idea but would prefer a more moderate version that perhaps uses some standard off the shelf bike components as long as they didn't make the weight jump too high. And DIY plans would be awesome too.

I have a couple extra timing belts and some of the idlers/sprockets(?) and stuff.. where does one come up with a belt drive (sprocket? What do you call it when it's belts and not chains?) big enough for the pedal side of a belt drive? I would love to experiment with belt driven bikes.

I figure the belt drive "sprocket" would be called a pulley.

If you aren't already in the know, McMaster-Carr is a great place to find random mechanical hardware.

I love this concept, and the use of a very pedestrian material.

Durr, of course it's a pulley, sorry I had a bit of a brain fart there.

I love McMaster, but sadly their pulleys in those sorts of diameters are cost prohibitive. If there was something I could strip used pulleys from that would be nice.

What will kids stick into the cardboard spokes to make motorcycle sounds? Daguerreotypes?

McMaster can be a little expensive. Maybe you could find what you want from Gates?
