My Polar S150 is supposed to measure speed and distance. It works by fastening the wrist watch onto the bike mount, such that two points on back of the wrist watch comes into contact with two points on a plate affixed to the bike mount.

The problem is that the wrist watch can't be fastened securely enough to the bike mount to ensure sustained contact between the points. As a consequence, I sometimes get a reading and sometimes do not. Are other people having this problem with the S150? Does anyone know a solution? Does anyone know whether both of the two points have to make contact?

I have the S150 and never had a problem getting it hooked on tight to the bike mount. Both leads do need to make contact. The only thing I think you could possibly be doing wrong is not threading the wrist strap through the top side the mount which is the only way to let the watch sit tightly on the mount? It should lock down pretty tight and not move around.

Simple solution for this. Buy a length of 1 inch diameter from Home Depot and cut a 2 inch length for the handlebar, watch strap fits around this like your wrist. Been using this for years and it works great. Good luck.
