Recycled Bike tire as fender

Prevent dirt form getting on you and the chain with the help of a fenders made from an worn out or damaged tire. This project used a damaged road bike clincher racing tire as a road bike rear wheel fender. Used, road side recycled, wire to attach the fender to the bike frame. Tire fenders are somewhat camouflaged, as it is tire looking, at first glance.

Using a tire from the same bike type is a good start as the fit is closest. The radius of the old tire needs to be larger when used as a fender so to fit over the present tire. The bead of the old tire bends to a larger fender radius only if the recycled tire rubber part is shortened by dimpling, by a wire spreader. The spreader holds the tire fender wider and dimples in the rubber making the old tire wider and a larger radius of curvature. Customize as needed.

Step 4: Put the fender over the bike wheel

In my road bike case the tire fender fits under the brake levers as shown. Use wire, bent to hook over the bike frame. I put the wire hook part on the bike frame piece holding the brake. In my case  the hook is over the horizontal bar. It pulls up by hooking the tire bead. The tension adjusted to hold the tire fender up against the inside of the brake levers. I found the tire fender did not interfere with my brake, you should check this to be sure. Adjust tire fender spreaders as needed.
Very good work.

The chain cover arrangement shown in the photos should help you to keep dust away.

Just for those that may not know it: the most important thing for keeping dirt away from the chain is to dry it after lubrication. Oil on the surface of the chain captures immediately dust, building this black mud that you see in the chain and gears of many bicycles. Lubricating a dirty chain makes the problem worst.

Try..recycling used stainless steel spokes for the  spreaders to avoid crappy looking rust stains.  Also, FYI, anytime a utility pole is downed or work is done on adding cables a stainless binding wire is often used and scraps are left laying around.  I have found "scraps "   several tens of yards long.   Scrapyards may have rolls of damaged stainless welding wire, if the rolls is bashed out of round, crimped or dented it will not feed in a welder and the yards will sell it for about a USD to 1.5 USD a pound.  Good for maille too.

Nice.
The last time I saw something like this it was a car-tyre on a motorbike. The piston-shattered so that bike never really worked...

I did not expect a reply so fast, how do you get notified so quickly that this new doc was posted? Did you make that car-tyre motor bike device?
I just happened to be looking at "recent".
My friend built a bike from an old MZ frame, Honda front I think, Yamaha engine he got from something abandoned by a canal, Honda-tank etc.. It was a horrible mess and it broke. But I like functional jobs like this - they work and that's the main thing.

The panniers look good too.
