Welcome prompterbob I had an A1c of 12.4 so I know where you've been. Last test 4.8 only taking minimum dose of Metformin now. As far as bikes I'd recomend you look at a Trek Fx series. I bought a Trek 7300 and don't care for the front suspension. Make sure they measure you for any bike. Don't trust a salesman that says you need a certain size frame by just looking at you. Another suggestion is working on your core strength. The stronger your core the more comfortable you'll be on a bike. I was amazed at what 2 months of pilates has done for me.
