M.I.T.'s technology blog takes a look at the French study,which comes to some interesting conclusions:
"Some of what they found is unsurprising. Over an average trip, cyclists travel 2.49 km in 14.7 minutes so their average speed is about 10 km/h. That compares well with the average car speed in inner cities across Europe.
During the rush hour, however, the average speed rises to almost 15 km/h, a speed which outstrips the average car speed. And that's not including the time it takes to find a place to park which is much easier for a Velo'v bike than a car.
Other results reveal the habits of the urban cyclist for the first time."
