Its not really a bodge, but for fun, we found this toddler bike and it had fixed cogs, front and back. We thought it would be a laugh to take the wheels off of it and put it on my trials, and seeing as i had ffw, we thought why not. So we took my front and back wheels off and replaced it with the little ones and had to resize the chain to get it to fit around the cogs nicely. eventually we managed to get it to work and it was so funny, the bike was so low, and the cranks were about a centremeter away from the floor, the gaering was easy too, as the back cog was 16t. I had a bb tool and a wrench, and the spanner was too big by about half a mm, so i got a coke can and jammed it in between the gap, still didnt work... Ive put a cable tie on an axle to stop the cone falling off, that worked for a surprisingly long time (about 6 months). My foam grip split, so I taped it back temporarily for that night. When my crappy tpa threaded, I put a ball bearing in the piston, so the pin pushed it down further, it made the pull amazing. I've put a bit of an inner tube in between an external bb cup and the frame to seal it, as I'd lost the o ring. I've put electrical tape over a hole in my inner tube, in a desperate attempt to sort my punny out . Thats all I can think of at the moment, but i'm sure there's loads more. Kiwi.
