One doesn't have to be a competitive fitness fanatic to ride a bike.... a lot.

Each person has to find what is right for themselves. I have several friends in their 60's and 70's, and I won't recommend they get an e-bike... unless they ask for help. I think they'd be much better getting out and just riding.

On the other hand, when I did the Crater Lake ride last year, there were one or two elderly women on E-Bikes.. and it made the ride possible for them, and it might not have been otherwise.
