The more useful case ime is turning cyclists with reduced mobility into regular cyclists.
In particular quite a few elderly people seem to have picked it up in my city, they aren't quite strong riders but definitely seem able of adapting to normal traffic. It also seems like a significantly safer option for individual transport than cars (especially in regards to the other traffic participants).
That's exactly my use case. I've got a bad leg and this thing made all the difference for longer rides.
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.
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.
I’d never heard of this and looked it up. It sounds awful.
You mean, turn weak cyclists into strong cyclists, like GP said? :-)
Don't be smarmy.
