You could use a hand winder, if the handle was on a big enough wheel like a bike wheel then it wouldn't take a lot of effort to get good results,.. I wouldn't think

you could also gear the system to get results from hand winding

I think if you had a second bike use the gears of that to increase the revolutions from hand cranking without having to increase the handle size too much. This way you could have a handle winding system that would not be too large to make it difficult winding with limited mobility
