I have a Garmin Edge 25 that I’d like to use on my Kinetic bike trainer this winter. I just want verify what I need for the Edge 25 to give me my speed while I’m on the bike. If I get the Garmin Speed Sensor, will that be what I need? And if so, will a different brand sensor also work? In the past, I’ve used a Cateye wireless bike computer, but because of the range limitations of that, mounting the computer was quite awkward. Just want to see what I need. Thanks!
