A downside of a GPS is that the battery life is relatively short.
A regular (non-gps) cycle computer will last for many months on one battery.
Another plus of GPS occurs if you have multiple bikes. I used to have wired computers and needed multiple mounts and multiple calibrations. GPS doesn’t depend on wheel size for speed and distance.
Battery life is a lot better than it used to be. The unit I suggested has a battery life of 30 hours. My first GPS had a battery life of 8 hours and cost about 4 times what that unit does.
