Training with GPS doesn't have to be all-consuming. Even if you're someone who worries about the simple pleasure of the ride being eclipsed by the overbearing features of your head unit, you still don't have to avoid all GPS computers. Garmin's Edge 20 Bike Computer provides the basic info you need for effective training without making you feel like you're spending your entire ride staring at a screen. Smaller than other Garmin bike computers, the Edge 20 and its slightly more advanced sibling, the Edge 25, were released to offer a replacement to the wallet-friendly Edge 200. The Edge 20 is the simpler of the two, and offers customizable screens that display total time and distance, average and current speed, current location, and calories burned. Garmin firmly stuck to the theme of simplicity with the Edge 20, so if you want to track heart rate or would like wireless capabilities, you'll have to upgrade to the Edge 25 -- the 20 is GPS-only, with no ANT+ or Bluetooth connectivity. It's operated using four buttons on the sides, which also allow you to quickly set alerts for pace, laps, time, and distance. When it's fully charged, the Edge 20 can run continuously for up to 8 hours, and it can withstand passing through a little rain or snow over the course of your ride without a problem. When you're back at home, you can use the included USB cord to upload ride data to Garmin Connect -- the platform gives you the opportunity to compare routes with others and keep track of your progress. If that's still a little too much reliance on technology, the Edge 20 has space to store up to 10 rides, so you can delete what you don't want and get back to enjoying the scenery on your next ride.
