Review on 🚴 Sigma BC12.12 Cyclometer: Enhance Your Cycling Experience with 12 Essential Functions by Jack Boldt

Bought two others (made in China) before ordering this Sigma. One was wireless, the other wired, both were sent back because they didn't work. Sigma costs $7.00 more than the others but was easy to install and has some youtube tutorials that really help set everything up. Also, I'm mounting it on a stationary bike with fixed wheels, so I didn't have spokes to attach a magnet to. I bought a small disc magnet that I taped onto the wheel and it works great. One of the guides explains how easy it is to set the wheel size unit. I am very happy. The product worked fine until I had to replace the battery, now it doesn't work at all. +
