Looking to buy or sell a bike? Head to the Bourse aux Vélos on October 2nd on the Boulevard Auguste Blanqui (13th, metro Corvisart or Place d’Italie). If you want to sell you bike come from 10am-12:30pm with your ID and a price in mind (you come back at 5:30pm to pick up your money or your bike if it didn’t sell). Note that the bikes have to be in working condition.
If you’re looking to buy a bike come by from 2-6pm. There is a €1 “consigne” and you get a number, then you can test out the bikes and take home the one you like with payment by cash or cheque.
There will also be a bike “tattoo” stand to get your personalized serial number attached to your bike and registered with BICYCODE. The association “Mieux se Déplacer à Bicyclette” keeps 10% of the sale price (they lobby to make cycling in Paris and Ile-de-France better and safer for everyone).
