I'm stuck riding a beach cruiser type of bike right now because my gut is too large.
I'm working on finding a good compression garment and weight loss, but it's very disappointing not to be able to ride any of my other bikes, yet. The upside is, the cruiser is pretty heavy and slow and I'm getting good workouts doing laps in my neighborhood. I hope you find a configuration that works for you. Since I saved some of my old bikes, I can at least do some test runs as my fitness improves. That's my goal, at least. I just started June 1, and have improved a lot in the last 2 weeks.
Happy riding!
