I also did this. When my commuter bike turned over 30K, I converted over it to a heavy hauler bike. Wald basket, low gears and all the hallmarks of a good, heavy duty bike. Commuting, I leave that to my Fixed Gear bike. The other day, I picked up bottled water when the water line had to be tuned off to be worked on. Yep, the old commuter bike answered the call.
