Kim, I don’t remember exactly when I started biking outdoors, but I think it was around four months post-op .
Biking was a little harder than I expected. I’d been pedaling a stationary bike indoors since about four weeks post-op, but riding a real bike is harder. You’re moving through space, which is like work, but also balancing on a bike takes more muscular strength and coordination than you might think. I don’t remember feeling frightened on the bike. Maybe I was and I tried not to think of it.
In the beginning, I was riding a boy bike. I had the range of motion to fling my leg over the back of the bike, but I felt really unstable and unsafe doing it. So, I would have a friend hold the bike upright while I got on and off. Later I wanted to bike by myself and I bought a girl bike at a yard sale, so I could step through the frame. I still use that bike around town, but I’m back on my boy bike for more serious outings now.
I’ve seen some people here say that their surgeons didn’t want them on a stationary bike until 6 or 12 weeks post-op, so maybe that’s a question for your OS, if it’s something you want to try. It’s great exercise for your hips and it will help you feel more comfortable when you’re ready to try a real bike. Just pedal slowly, backward at first and then forward, with no resistance. Start out just doing 5 minutes on the first day and increase the time and resistance from there, depending on how you feel afterwards.
Also, if you can do some core exercises for your abs and lower back, that will help with balancing on the bike. Actually, core exercises will help you with everything as you get more mobile. So many of us develop back problems after THR and those exercises can help you avoid that.
