For obvious reasons of available space, you are not allowed to carry your bicycle on the metro, bus, tramway or Montmartre funicular.
On the RER, you may transport your bicycle and make transfers only between RER lines A, B, C, D and E, and only during the following hours:
- All day long on Saturdays, Sundays and bank holidays,
- Before 6:30 a.m., between 9 a.m. and 4:30 p.m., and after 7 p.m. on all other days.
You are responsible for the transport, handling and surveillance of your bicycle. You must store your bike in one of the compartments with a special bicycle indicator (bicycle sticker) and hold on to it.
You are not allowed to use the escalators with your bicycle.
The use of roller skates, skateboards, scooters, bicycles or any other type of cycle is strictly forbidden within the network and in the trains, regardless of which transport mode you use (RER, metro, bus or tram). You will be held fully responsible for any accidents that occur to you or to third parties, as well as to RATP and its staff.
