Other might just give you total time and moving time from which one may calculate moving average. Also a city ride is quite bad at giving realistic data on average speed because of stop & go traffic. | |

Most likely, the problem is due to a combination of a) the way speed is measured, and b) the fact that it's the lowest speed that dominates the average. If you do 1km uphill at 10km/h, that's 6min. If you go down the same 1km at 60km/h, that's 1min. Total: 7min, or an average of 2km/7min = 17km/h. That's much, much closer to the uphill speed than the downhill speed, simply because the uphill dominates the total time. Add in a few traffic lights at 0km/h and, ..., well, you get the idea...
