The Garmin Edge 800 bike computer is the first-ever touchscreen bike computer and it is fully GPS enabled. Full color maps, turn-by-turn directions, and incredible custom displays deliver your data where you want it, when you want it. This is the best bike computer we have ever tested, bar none – its waterproof, tough enough for mountain biking and you can even add custom SD cards to get full topo and trail maps or street maps – it’s your call.
