I am currently riding a coaster-brake single speed to and from work. The rear hub is crap and I would rather have a flip-flop hub on the rear. Is it as easy as removing all the mechanisms on there and putting the wheel in, or is conversion needed? The bike is from Indiana University's Little 500 (http://iusf.indiana.edu/little500/ri...500-bikes.html), and there are no quick release levers...just washers and hex nuts. I know I'll have to put a brake caliper/lever on, but the coaster brake mechanism allows leads to slack in the chain every two months or so.
