I have the same issue. I have arthritis in my lower back and when I am done riding, it is very difficult for me to get my leg over the seat to dismount. As Zen said...I do the lean and lift, as well. I have not fallen yet, but it is not really graceful and I am hoping with more time on my bike it will get better or at least a little more graceful! Just wanted you to know that you are not alone!
