The Garmin Edge 500 with Cadence and HRM has been a steadfast standby in the world of ANT compatible on bike computers for quite a few years now. It's no wonder that Garmin keeps it on the table even after introducing the Edge 800. The 500 is, first and foremost, a smaller package than the 800. With this downsizing comes two screens for data that are fully customizable. You are able to see times, temperature, altitude, gradient, speed, and cadence. It is also compatible with ANT enabled power meters. The data you won't find on the 500 is in ride mapping capabilities. But after your ride is complete, the coordinates are saved so you are able to see your route. Additionally, there is no virtual training partner, which is especially nice on those off days when you just want to cruise. Like the rest of its Edge group, the 500 is compatible with Garmin's Training Center Program, which works on PCs running Windows XP or newer and with Intel based Macs running OS X 10. 4 or later. The data can also be uploaded to the Garmin Connect website for free, and to Map My Ride, Strava, WKO and TrainingPeaks.
