Mougins is very hilly and while there are bike trails the relative narrowness of the roads, and the steep grades mean it is biking for the very experienced.

Bike friendly: there is a dedicated bike lane from Antibes to Nice. Many people ride bikes, with several bike rental options in town. But riding around town is not for the faint of heart – the streets, both pedestrian and motorized, are almost always crowded in the summer, on market days, and even sometimes in the cooler months. That being said, there are so many places in the surrounding countryside to ride (if you like hills).

Car difficulty: Free parking – very difficult most of the time. Paid parking – numerous city parking structures in the central city, and paid Port Vauban parking almost always has spots available. Expect to pay 10-$30 per day, or $80 to $120 per week for parking. You don’t need a car if you are in the central city. It’s easy to rent a car from the train station if you want to explore the surrounding areas.

Nimes is a busy city, but not unusually difficult for bikes.  Like all older European cities, you'll find you have to squeeze by in the narrower streets.

Dinan town itself has mainly steep and cobbled strees so is not good for biking.  There are multiple good biking trails with mostly flat terrain nearby

Typically the 'reasonably bike-friendly" town you can expect in France. Cycle along the Val au Cesne, a former railway line that has been converted into a long-distance cycling trail. The Val au Cesne passes through Yvetot and connects it to other towns and villages in the Seine-Maritime département.: Enjoy leisurely rides on flat and well-maintained routes like the Voie Verte du Val de Seine or the Véloroute du Havre, perfect for families and casual cyclists.

Typically the 'reasonably bike-friendly" town you can expect in France. No real complaints or special draws.
