“What's your 20?”

The Garmin Edge 20 strips away the frills for a simplified GPS experience that displays speed, average speed, distance, time, and GPS-calculated ascent. If you're feeling like discovering some new roads, courses can be uploaded directly to the Edge 20, or upload a course you've done before for a little competition against yourself. GPS / GLONASS satellite reception will keep tracking location even under dense tree cover, and the durable and water-resistant construction houses a built-in Li-Ion battery for up to 8 hours of uninterrupted recording. When you've hung your bike up at the end of the day, your ride can be uploaded for analysis to Garmin's Connect website using the included USB cable.

Device measures 1.6” x 1.6” x 0.7”. Claimed weight is 25 g.

Keep it simple, stupid

Small, light, all the info you need. Transfers to other bikes with different tire size easily. Small learning curve, especially keeping battery charged in cold weather, and remembering to turn off and on. Off to save charge and on for time to start tracking. No wires, comes with 2 mounts, easy read screen. Amazing product.

Finally someone comes out with a GPS bike computer that's small, light and totally wireless, like it should be !

The set up is easy and the free synching with Garmin Connect and Strava online is a breeze. It's really fun to do a ride, then check into Strava for terrain profiles, slope percentages and how you compare with other riders who've ridden the same roads. I really like how you can tailor the screen to any configuration you like. The biggish numerals are easy to see while riding. It comes with clean looking, low profile barstem mounts for 2 bikes so you can just switch between them. No wires, magnets or wheel sensors. Some people mention using a separate wheel sensor with it but that's unnecessary. Mine gives me accurate speed distance readings every time. Being both U.S. and GLONASS satellite compatible, it only takes about 5-10 seconds to lock onto a signal. The only aspect that isn't always totally accurate is the altimeter. That's because it relies solely on GPS rather than barometric pressure for that data. But it's close enough. And the 8 hr. battery life isn't a problem unless your on a multi day tour with no access to a power outlet. Actually, I tried charging mine with a portable charging stick and it seems to work fine.

To sum it up, this little unit does what it's supposed to do Provide you with just the basic information you most need without clouding the issue with a bunch of unneeded bells & whistles.
