second thought, without altering the casette, I could run an 11t from the engine to a 30t on the jackshaft, then on the other end of the jackshaft another 11t, then down to a 30t on the left side of the bicycle crank. my first gear shift should be at 10mph without altering anything on the bike besides removing the pedals.
I don't see why removing the pedals is such a problem. Does it make the bike illegal?
