Like @rivermaya34 , I too wondered about a bike, it would be a burst of freedom! Biking was a major activity, along with running, before I got struck by neuropathy. I ride a stationary bike at PT each session, and with my condition, and with resistance, 10 minutes is all I’ve been able to take.
My fear isn’t as much balancing while riding the bike as it is getting my bearings and land legs back when I dismount! But I’m honestly considering a tricycle bike: easy resistance and dismounting. Good, safe, fun exercise, and with baskets so I can ride to the store and shop. I don’t care if it looks funny to others, I got past that when I started using walkers and canes!
