Had a customer ride the MS 150 on a Giant Suede. Semi crank forward design, 7 speed. She was 75 yrs old at the time. An amazing person demonstrating that it really is not about the bike. It is all about the will and drive of the rider. Just think about how the Great Wall of China was built, the pyramids of Egypt, etc. They had a will do get it done (plus a lot of slaves).
