Fixing a Bike Inner Tube and a Rain Shoe 1. Fixing a Bike Inner Tube. A bike inner tube was leaking on air, there is no way to inflate the tire. Take the inner tube out: Inflate the inner tube, soak it in water, find a leaking spot: Use these tools: The Classic Patch Kit, from Amazon, $4.98: File the broken part with a file (the red square, the cap of the kit), and cut a patch (the green circle): Work outdoors, not indoors. Clean the filed area with alcohol, spread a layer of rubber cement (from the Classic Patch Kit) on the tube (I always wear a gas mask (the smell might be harmful, with this mask I could not smell it at all)): Peel off the protective plastic film from the cut patch: Put the patch onto the tube area with cement and press it with hands: Wait for several minutes, inflate the tube: Make sure there is no leak any more in water: Deflate the tube: Reinsert the inner tube on the wheel: Inflate the tube, now the bike is standing with the fixed inner tube: 2. Fixing a rain shoe. The cut was done by my sickle when I was cutting wild grass. Ironically, the brand new shoes were $5 several years ago, now the Classic Patch Kit is $5 too: |
