One of mine is a Cateye Padrone wireless. It can be taken off the handlebar simply by unscrewing the knob from the mounting strap and then strapping on another handlebar. I have sensing magnets on a spoke of a few different bikes, so all I have to do is moving the computer/strap from one to another. Takes a couple of minutes. If you want to keep track on the stats on each individual bike, it will not do that. You would have to keep a log.
