Speak for yourself, if you can bike with asthma I'm happy for you. Mine is exercise-triggered and anything above a walk lays me right out. Being anything other than a pariah on a bike path requires a minimum level of energy output beyond what I can sustain. Or are you my doctor now?

It is possible to cycle with less effort than walking, even with a bike with no electrical assist, what I was saying is that you don't need to exert yourself. Maybe you consider that being a pariah, but that's how in cities like Amsterdam and Copenhagen you see people cycling well into their 70s and 80s.
