Okay, so i got myself a cyclops indoor cycle. Kinda like a spin bike, yeah that one. I want to be able to log my miles and keep track of all miles ridden in the year. On the indoor bike, i don't care much for cadence, heart rate, etc. Just distance. I got a Bontrager speed sensor and figure i can mount it on the metal flywheel and use my Garmin 500 to log speed and distance. Will this work right, how accurate will the distance be. I am overly guessing it maybe, read a few things that distance can't be accurate. But if i put in the diameter of the flywheel, shouldn't it be pretty accurate. Thanks
