I'm 64 and in reasonably good health. I could still ride in position 2 if I choose to, But have only one bike and opted for a comfort bike, Position 5. Bolt upright. I had a cheap mountain bike that was awful. I ride mostly for pleasure and excersize. I love this Giant Sedona and can ride it for hours without fatigue or discomfort. I usually get bored before I get uncomfortable.

That said, I wouldn't mind a 2'nd more aggressive bike to try out. Might try a local used bike, perhaps a road bike. Problem is I probably need a small frame for enough standover height with my 28" inseam. I even considered a low entry/woman's style bike. With a rear trunk bag that high top bar makes getting on and off pain. Even without the rear carrier and bag, It's still not easy for me to get on the bike over the seat.
