>>> The RATP has recently launched a programme which enables passengers to take their bicycles with them on the metro and RER, subject to certain conditions :
For the time being, bicycles can only be transported on metro line 1 (Château de Vincennes/La Défense) every Sunday until 4.30 pm. All stations on this line are equipped with special large doors to allow easy access for bicycles (apart from Louvre - Rivoli and La Défense).
Bicycles are not yet allowed on the other metro lines.
On the lines RER A and B bicycles can be transported in the purpose-built coaches located at the front and rear of the train and identified by a 'bicycle' pictogramme.
Bicycles are allowed on these lines at all times apart from rush hours on weekdays (6.30am - 9am and 4.30am - 7pm).
If you are travelling inside of Paris interchange is allowed, but you must stay within the RER network. If you leave the network and wish to travel again, you must buy another ticket. The following RER stations are not yet equipped with special large access doors : La Défense, Charles de Gaulle - Étoile, Auber, Châtelet - Les Halles, Nation. RER B : Châtelet - Les Halles, Saint-Michel - Notre-Dame, Luxembourg, Port-Royal, Denfert-Rochereau, Cité Universitaire.
Passengers must keep their bicyles with them at all times, and make sure they do not inconvenience other passengers. Please note that for safety reasons, bicycles may not be ridden in the station platforms and corridors and may not be transported on escalators.
