Ghost bikes, much more than tributes to deceased cyclists, are increasingly developing in urban public spaces. The most publicized is the one placed in April 2019, a year after the death of the parliamentary assistant, Armelle Cizeron, killed by a truck driver in Paris.

White bicycles are not intended to remain permanently in public spaces, says Alexis Frémeaux, president of the MDB (Better Travel by Bicycle) Île-de-France association. The ghost bicycle is an invitation. To remember, to pay homage, to question the road infrastructure and to look out for others.
