A couple of weeks a go I held a beige 201K23 in my hand, case, accessories and all, and it was well within what I lift with out thinking much of it. I can't say that about carrying my cast iron 201K up a few stairs, and then down a few stairs. Then I came across proof that an aluminium 185K exist, and it should be even lighter than a 201K23. The unfortunate thing is that not all 185Ks are aluminium, some are cast iron. There is a hand crank 185K for sale here, asking about £30 for it. The problem is I need to add motor and lights, and seller can't guess how heavy it is, nor put it on a scale, and its' a long ride out of town just to see it. I probably shouldn't bother, someone looking for a hank crank can have it. I don't think many hand cranks shift owners these days?
