Take your ride to the next level with the Edge 205 Bircycle Navigator, Garmin's GPS-enabled personal trainer and cycle computer. Whether you're a competitive racer or weekend cyclist, Edge will help you achieve your personal best. Rugged, lightweight Edge 205 attaches easily to the stem or handlebars of your bike with the included bike mount. Just turn it on, acquire GPS satellites and go. Edge automatically measures your speed, distance, time, calories burned and altitude, and records this data for your review. For even more detailed data, get the Edge 305, which can track your heart rate, cadence, climb and descent. Other Edge Motorcycle Navigator features Virtual Partner lets you race a virtual competitor over a specified distance and speed. Courses let you race against a previously recorded workout, so you can compare your current and past performances over the same ride. Auto Pause pauses the timer when you slow down or stop and resumes when you speed up again, so you can focus on your ride. Auto Lap automatically starts a new lap each time you pass a specified location or travel a preset distance.
