Hiring/buying a bike
Why not talk to your colleagues? They may have an unused bike in the garage...or just put an add into the CERN market.
Otherwise, it is possible to rent a bike for free (or at least free for the first...
Some possibilities are:
- Association pour la Récupération de vélos
- Fourierre Velo
- OLX. You can sign up and place an advert for a bike.There are often people advertising their second-hand bikes for sale.
