Bought a bike about a year ago (used) that has a Cateye computer on it. Works reasonably well, except that one of the wires came loose (or I guess that's what's wrong), and it now only senses the pedals, not the wheel any more. Thinking about chucking it and using a GPS instead - gives most of the info I want - speed, distance travelled, etc, and far less complicated to use as well. Also no pesky/ugly wires running up and down the tubes, not to mention the sensors. Anybody have experience with a GPS on a bike? They make special brackets to mount a standard unit (which I already have) on the handlebars.
