    Average Speed means different things on different cyclocomputers?

    On my old bike, I had a Cateye Strada. When I stopped, for example, at a red light, the trip time counter also stopped. At the end of the ride, the calculated average speed was the distance/time traveling. When I bought my new bike, I installed a Sigma B1606L, and I assumed it worked the same way. However, recently I noticed that the trip time does NOT stop when I stop at red lights, and that Average Speed reading actually counts down while I sit there waiting for the light to change. Suddenly, I miss my Cateye!

    so of the major brands/models of cyclocomputers, which ones sense when you are stopped and stop the trip time?

    Both of the computers I use, two Cateye Mity 3s (of some age) and a new Knog NERD 9, calculate average speed using ride time, i.e. time in motion. They both stop timing when the bike is stopped.

    I suggest looking in to your Sigma's settings. I have both of those computers and they seem to work the same for me, i.e. time stops when you are not in motion.

    Yeah, I checked, but didn't find any relevant information

    I had a Sigma (a few years ago, not current model). It did the same -- it did not time out for stops.

    I have a sigma 1606L and mine calculates trip time only when moving also. Are you sure you have trip time and not time up, down or stopwatch?

    Wireless? Does this happen all over, including further away from the city? You might be picking up a slow signal of some kind, enough to keep the time running but not enough to display speed. (I've never had a Sigma, though it probably handles interference better than the cheapo wireless computer I used to have.)

    Otherwise, did you do this several times? If you stop at a light with the magnet right next to the sensor, normal little back and forth movements could do the same thing.

    I always counted my time from garage door open to garage door shut, calculate from mile ridden. Maybe that's why my average is so low!

    My BC1606L works like it "should" as in it only changes average speed based on time moving. It's a wired version though, so I can't speak to the interference problem, but it worked this way right out of the box. My previous Sigma computer (now on the wifes bike) works the exact same way. Wierd.
