Hi all. I bought a new bike and got a Garmin Edge 25 bike computer at the same time. It is going back to the shop ASAP. The guy at the bike shop had trouble syncing it. Put a new battery in and figured that was why. Well, got it home, it doesn't work. Period. Doesn't track anything and goes into pause immediately. Can't tell if it is still synched or not. Don't know how to tell. I did some research trying to solve the problem and discovered that is seems to be an ongoing problem with these units. I don't know yet with what I will replace it. I need something with Ant+ to sync up with Zwift. I want it to track miles, speed, and cadence and want that to happen inside and outside.


I am considering the Garmin 520. Will it work in the house and track miles based upon the tire rather than just based upon GPS? I want a computer that will track miles based upon tire rotation not just GPS because I want to know how many virtual miles I am putting on the bike while on the trainer for maintenance purposes and honestly so that I can easily assess how much riding I am doing. Most of my riding is actually done on a trainer using Zwift. I can't always take time to go outside. Plus, of course, over the winter, I ride inside.


I only want speed, distance, and cadence. I might just take the old computer off my old bike. It isn't Ant+ so I also put an Ant + cadence sensor on the old bike. I have an combo speed and cadence sensor for a wireless CatEye and then a CycleOps Cadence Ant+. The Ant+ syncs up with Zwift and the combo sensor syncs up with the bike computer. Works fine, but was hoping to move to one computer with one set of sensors to do it all.


Any suggestions?
