I enjoy reading the "Still riding" threads in this forum and gain inspiration from other, older cyclists. I'm only 64, but wonder how many of us are out there with physical impediments, still riding conventional bikes. For instance, I've had Parkinson's for 15 years, and even required a cane to walk, yet I was always able to ride a bike. Still able to ride 20-30 miles at about 15 mph and enjoy it. No one would guess I'm handicapped by watching me ride, but when I dismount my unstable gait gives me away. This is not uncommon for people with Parkinson's. Are there others with similar stories?
