Ranking Bordeaux and Nantes next to Amsterdam is nonsense.

Amsterdam is miles ahead in terms of infrastructure. This ranking dilutes the most important thing to get these results : good bike lancés everywhere with no discontinuity.

Disclaimer : I've built villes.plus, an open source automated evaluation of bike lanes. 100 points, compute itineraries in "secure" mode with Brouter between these points, count the % of secured km -> score.

Amsterdam tops at 8/10. Bordeaux is at 3/10, Nantes 2/10.

I can't speak about Nantes which I haven't visited for decades but I think it is wrong to count bikes lanes as a single parameter.

Dutch urbanists have found that bike lanes are very important when streets used by cars are unaltered. Once you implement a lot of traffic calming features and cars never reach 30kph comfortably, bike lanes aren't that important and then streets can be shared across all users.

Fun fact Amsterdam recovers roughly 15000 cycles per year from their canal. IIRC they have a board with the number for each year

What does it mean to be "secure"?
