I commuted a year on my Cannondale SuperV here in Florida when I did not have a road bike. What I did was get rid if all but the biggest ring and lock out the front derailluer. I then swaped the front ring for a 48t which was the biggest my crank could work with at the time with the stupid 94mm rings. I then locked out the rear shock and only locked the front shock when I was on flats mainly. I also put Electra beach cruiser tires on it that can withstand any glass or broken object in its way. The biggest problem I had was being flat here in Florida I found myself in the highest gear most of the time. Now that I have a road bike I use it to pull the kids in the trailer to the park on the weekends.
