Love the Sunny indoor bike but this sensor does not do anything. No BT connection, no iPad or iPhone connection. It does have a pretty blinking blue light however.
Won't switch from cadence to speed no matter how long I leave it. Worked okay in the cadence mode, but I couldn't see the resuls of my ride until after the workout program was done. I had to go to my completely different app to see my current stats.
Great addition to my Sunny bike! I love being able to see my stats on the screen. The cadence makes information more accurate since it is connected to the app.
