I am impressed by your solution and I took have at least one bad leg. I have decided against batteries in favour of a basic bike that I can park anywhere and carry up stairs. I want the little and often mobility with a few longer rides over summer. I also have a neighbour in his late seventies that rides 'naturally aspirated' with a buddy that is two years older. His buddy has an ebike and he is giving it a couple of years before he goes electric.
Being younger than him, I feel that I need to stick with 'naturally aspirated'.
I am interested in going the other way to get a dynamo with that switchable between lighting and USB power, for my phone and speakers. There is 3A at 6V to play with.
Ultimately I would want mild hybrid, with regen so all assistance is pedal powered.
I'm 60+ it was either the e-bike, wreck my leg even further or take the car. That was an easy choice :)
Be careful with what you've got... I wish every day that I could do the day I messed up my leg again without making that particular mistake. I rode a low racer recumbent at speed and had a nasty case of leg suck when hitting a (new to me) speedbump.
It is. Life changing event that one. And it is not just trikes, low racer recumbents have the same problem (only worse, because they are much faster, they are probably some of the fastest bikes you can ride). I was literally airborne for a bit after already breaking my leg so this was the worst of all possible combinations other than that my head was not impacted at all due to posture (and wearing a helmet).
