In 2005, the French city of Lyon introduced a shared bicycle system called Velo’v that has since inspired numerous other schemes around the world.

Velo’v differed from earlier schemes in its innovative technology, such as electronic locks, onboard computers and access via smart cards. The system now offers some 4000 bikes at almost 350 stations around the city. (…)

Since its introduction, the system has kept track of the start and finishing location plus travel time of every journey. Today, we get a detailed analysis of this data. (…)

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. (…) During the rush hour, however, the average speed rises to almost 15 km/h, a speed which outstrips the average car speed. (…)

Curiously, the Wednesday morning speeds are systematically higher than on other days, even though there is no change in other factors such as the number of cars. This, say Jensen and co, is probably because women tend to stay at home and look after their children on a Wednesday in France. So the higher proportion of men pushes up the average speed.
