wheels of steel
I would like solid tires for my bicycle so that they can’t pop, and i don’t have to fill them. they make them for wheelbarrows (out of weird blue rubber that reminds me of eraser caps, the pink kind that you put on the end of your pencil, but they actually just leave black marks instead of erasing because the rubber is too hard?), why not bikes? the first bikes had iron wheels, which I’m sure was bad for shock absorption, but in this modern era of synthetic plastics we can’t come up with something better?
my front bike tire has an annoying slow leak, slow enough that it doesn’t feel urgent to take it off the rim and patch, but fast enough that it feels likely that hitting a bad pothole would blow out the side…
