I'm a "senior" that has been blessed with good health. An e-bike is not for me (at least not yet). I ride on and off-road, and the hills are a little harder and I'm slower at getting to the top of them than a decade or so ago. But so long as my health holds up, I'll be pedaling. Might be some hills that I may even have to walk part of the way,, but that's ok with me. Hoping for a decade or two before I'm needing an e-bike, but glad they are available for those that still want to cycle, but need the assist.
