What customers say about "Key Specs"
Garmin Edge 510 GPS Bike Computer
  • The GPS seems accurate and acquires a signal quickly. I love Garmin connect, especially compared to the Sigma data center.
  • It's easy to modify what fields you would like to see on the fly. Switching between bikes is a flash.
  • GPS fix is really fast with the GPS + Glonass configuration.
  • Altimeter works great and the altimetry shown during your ride is really accurate.
  • There is currently a known issue in which all ANT+ sensors randomly drop out and both show and record bad data making this useless.
Garmin Edge 520 Bike GPS
  • Easy to use, no issues with connection, great set of items to display.
  • The size/weight is perfect, screen is always legible.
  • I like the size, features and downloads to my iPhone.

What customers say about "Display"
Garmin Edge 510 GPS Bike Computer
  • I like the screens that can be displayed and without my glasses I can read it quite easily.
  • The display is great and I have no trouble reading it even in sunlight.
  • Screen can display up to 10 different real-time data points simultaneously.
  • I do like the screen size and the backlight is nice for indoor or night/low light rides.
  • I finally went with the 510 because I finally realized it screen size was much bigger and much better.
Garmin Edge 520 Bike GPS
  • I like the compact size, yet still a big display.
  • Display is bright, and I was surprised how readable it is considering it's color display.
  • The larger display compared to the wrist models is great, and it has true mapping capabilities.
  • Screen size is good. Not too big and not too small. It has enough squares to get the information I want on the screen.
  • There was so little contrast on the display that it was practically unreadable no matter the lighting.

What customers say about "Features"
Garmin Edge 510 GPS Bike Computer
  • Virtual Racer, especially, is cool lets you use a stationary trainer like a pre-programmed exercise bike.
  • One my favorite things about this device is the virtual partner, so when you are doing training by yourself it will give a boost of confidence to challenge yourself.
  • The Garmin drivers for my Mac are cool, in that Strava's website can get direct access to the GPS and post my latest ride.
  • My phone (Galaxy S2) doesn't have ANT+ support and most cadence/speed monitors do not work with bluetooth.
  • The weather alerts are absolutely ridiculous.
Garmin Edge 520 Bike GPS
  • With the auto scroll setup I'm able to see more data and my route.
  • I'm using bluetooth to sync to my phone and finding the Garmin Android app to be much more useful than it was with the Garmin 25.
  • With my mobile phone's bluetooth, I'm able to effortlessly synch my ride to garmin connect and auto upload it to my Strava account.
  • I added a speed transmitter primarily for indoor training, then I added a rpm transmitter and I just added a heart rate monitor transmitter. The information it supplies me is great.
  • Constantly says I'm off course when I'm using a pre-planned route.

What customers say about "Battery"
Garmin Edge 510 GPS Bike Computer
  • Battery life is pretty good and re-charging is fast.
  • Battery life is more than ample for the longest rides.
  • The battery life is much better than my 305.
  • Battery life is not great, not anywhere near what the 500 was, maybe 50% of it.
  • Battery life could have been better!
Garmin Edge 520 Bike GPS
  • After 3 hours of use the battery is on track to last about 10 hours with gps.
  • One thing that I have enjoyed is the long battery life. I ride about 140 miles a week which takes 7+ hours and only have to charge it about once every other week.
  • Love this, battery life is great.
  • At night there is a backlight that does drain the battery somewhat rapidly.
  • Battery runs down after only 3 or so hours, so it has to be charged after every ride.
