A belt driven BMX. I have done a little bit of research, but not much has come of it. I was thinking about using a timing belt assembly for the drive system and milling it out to fit a casset hub and a bottom braket. I'm sure I could find a way to make all the spacing and such work, but i'm stumped on how to run the belt.
I have to somehow run it through the frame. In that photo it appears the frame has been cut then had a sleeve (clamp?) of some sort placed over the the spot on the frame. are there any good alternatives to this? Any other suggestions on what to use for the drive system other than a chain and sprocket (no shafts either)?
