Cycling
If you don't want to leave Nice itself there are a variety of activities available including e-bike tours. The most popular place to cycle is along the Promenade des Anglais which has a designated cycle path.
You can use your own cycle or rent a bike from one of several hire shops or even use a Vélo Bleu, one of Nice's ubiquitous blue bikes.
There are also opportunities to take your cycle out of town and explore routes on the local coast and inland.
