I mounted one last weekend but it snowed about 8" so I haven't tried it yet. The setup was pretty easy. I'm also trying to order another sensor, etc. so I can run it on 2 bikes using the 2nd bike option.
The only down side I see on setup is that the sensor is large and doesn't seem that stable when mounted. We'll see.
Cadence, speed and hr worked when testing on the bike stand. Damn snow
