Cycling in Ubud? (Bali)

Hello everyone!!! I'm happy to be a part of this community and this is my first post! My husband and I are traveling to Bali in mid April for our honeymoon and I was hoping someone on here might be able to help me. I have advanced osteoarthritis as a result of a severe injury from 3 years ago. It's hard for me to walk for prolonged periods of time. My doctor and I have been trying to hit my pain management from a few angles for our trip, but the one thing that always helps me when I get to a new place is finding a bicycle. If I can get on a bike I'm golden. We are staying in Ubud. Is there somewhere anyone can recommend that I can rent a bike for 4 days, and is it safe for us to ride around Ubud? I've had people tell me different things. Thank you in advance for taking the time to read my message!
