Thanks so much for all the great suggestions. The trikes do look like a lot of fun.....I'm learning a lot. Lowering the seat , feet on the floor is a great idea. I used to do walkovers on the balance beam so balance will come I expect. My weight makes me feel cumbersome but will def. figure it all out. Am up to 5 miles a day this week between the in and out and loving it!
Cool bikes to look into!
