Well, last September my doctors said I wouldn't pedal any more due to permanent quad muscle and femoral nerve damage. The "physiatrist" suggested an "adaptive sports center", ie: hand operated trike. That seemed extreme, something for paraplegics. Primary care suggested an ebike. I followed up on that suggestion. I don't think it has the battery range to embark on camping tours but it has me back out riding locally at a normal pace again.
No, despite all the hate talk in the old linked thread it is not a lazy cheating thing. My torque sensor rewards more me the harder I work. I used to twiddle up the 2 mile hill to my house in the granny gear at 5-7mph without even breathing hard. Now I blast up in the big chainring at 15-20mph... winded, exhausted and exhilarated at the top, passing teenagers on their racing bikes.
Many of you 50-60 somethings will soon be a 70 something. Despite all your past and current accomplishments, that ability can change overnight and you could be next. Disability happens. Only 8 years ago I was riding the TransAm. That said, any 20 something that jumps on an ebike will have a smile on their face.
