I could cut the big wheel off but that is even a bit to hillbilly for me. So I installed a cheap Shimano sealed BB and put it back together.
You might consider cutting/grinding the teeth off the 48 chainring, just leaving it in place as a outer guard. You shouln't need the inner 28 ring, if you are on hills/conditions steep enough to warrant using the 28 then faster to get off and run.
