I've been thinking for a long time about getting some slicks to put on my wife's X-mart mountain bike to see if that helps her enjoy cycling even a little more. With her it's sort of a cycle, she's got a crappy ill-fitting bike but doesn't want spend money on a new one that fits properly because she doesn't enjoy riding and doesn't do it much. But, IMO, part of the reason she doesn't enjoy it is that she's got a crappy ill-fitting X-mart bike (suspension fork Schwinn Ranger by the way that she bought before we were married after I took her to like 3 different lbs to check out the options).
