Hi monica
Lucca is very very nice!!! nice choise if you are going there, I been in Lucca with my family 2 months ago, it was a unique experience .
Inside the town there's no car, you haven't problem to ride , it was wonderful!! especially in some pavillion there are playgrounds and my childrens love it !!!
I advice you to rent bike in a shop near the train station, I've been there and the rates are very economic compared to other shops inside the town, the staff is very cordial, this is the link of the shop:

They also rents bike for more than one day, and they tell all the informations you need
Hope to help you!!!
