Introduction: Bicycle Parts Belt

This is from Napalmandroses' bike parts belt idea in the bikepirates thread here.

Step 1: Acquire a Used Bike Tire and Trim Off the Bead & Sidewall - I Have a Bontrager 700x25 Here.


Step 2:

I didn't have two matching cogs, but a section of a larger cog will do for a second ring. I cut it into sections with a Dremel cut-off tool as in the bottle opener directions.

Step 3:

Thread the tire end through the two "rings" and make holes to put the master link pins through. I used a c-connector single speed link to fit the thickness of the doubled-up tire.

Step 4:

Try on and trim the end to length. The belt hooks up much like a D-ring belt. Alternate pictures two and three show another partial chainring instead of a small cog, trimmed, with two teeth removed on the top piece.

anyone know if it's possible to flatten out the tire rubber?

only if you have a REALLY HOT oven & a 120,000 ton press.

Hmm, Well, I'll have to work on that ;)

It's tough, but manipulating it (folding, rolling opposite direction, etc), then putting some weight on it may help. I tried this with two different tires actually, and the wider, stiffer tire ended up lying flatter in the end.

try stretching it flat and then putting a weight on it. after wearing it for a long time it should naturally stretch and flatten

you could use a heat gun and plyers maybe

I ended up using your design instead of Napalmandroses', just tweaked a bit - if you don't have the tools to cut a gear, just use a smaller gear for the second ring. Worked great for mine! Took just a few minutes: cut the tire, fold it over your two rings, rivet in place, round off the other end. Done! :)

I have an old rusty bike lying around, and want to do this, but how do I get the gears off?
