Sigma BC 7.16 ATS Bike Computer (Black) (Wireless)

This computer is excellent! I'm not sure why others have had difficulty setting it up because I thought it was a breeze. The speedometer works perfectly, and I intend never returning to some of the other brands. In fact, the only reason I changed brands (from the one starting with a C), is that two consecutive computers continued to misread my mileage. I have had no issues whatsoever with this one. I especially like the "average speed" mode. My only issue is that the computer installation rubber band was not long enough for my road bike handlebar thickness. I had to use the fork sensor band, which was a bit annoying, leaving me to use an older band I previously had for the sensor receiver on the fork. I'm not sure this could have been anticipated so I won't hold it against the outstanding performance of the unit.

Yes, it's hard to install and the instructions leave a lot to be desired. A few words here and there would help a lot. I have a trike with 20inch wheels. The speedometer works great if I am going faster than 5 mph. If dip below 5mph, the speedometer registers twice the actual speed (turns 5 mph into 10mph), and twice the actual distance which makes the trip distance measurements worthless. If you never ride your bike less than 5 mph, this speedometer is for you. If not, better find something else.

I got this computer as a gift. I would not purchase it. It was extremely hard to program as the reset button is just slightly larger than the letter "o" in this posting and is in a clumsy location on the back of the computer. I found that quite annoying. The instructions were not that easy to follow. As for performance, it appeared to keep accurate mileage, etc. When I tried to switch it to a new bike, there was a small plastic tab on the computer body that broke, rendering the unit unusable. Save your money and buy something else that's user friendly.
