I bought two of those Schwinn computers; one for me and one for my wife. After a ride, I noticed mine had popped loose from the bracket and was gone. I searched for it but never found it. Later, I borrowed the one off my wife's bike, and lost it, too. There must have been something wrong with the bracket on my bike. I replaced it with a Cateye wireless which has worked flawlessly.

I also had one of those Schwinn tire pumps and it gave up the ghost after about 1.5 riding seasons. I replaced it with a Blackburn that is still going strong.
