Well.....that middle hoist is identical to the one that Harbor Freight sells.....for $9. Yes, I said nine dollars.....

Bicycle Lift

I've used several of these over the years, and they work fine. IMO, their weak link is the rope....the mechanism/hardware is up to the task of any of your bikes. You could replace the rope with something a little heavier and still be WAY under the cost of the links you posted.

Heck....I've got a bunch of these in a box out there that I'd send you for the cost of the shipping, if you want to try one.

BTW, you don't have to use the seat as a rear hanger....I used the wheel on mine.

Our triplet hangs from my shop ceiling on a motorized hoist:

I don't have a good pic of it, but you can see it how it generally hangs in this one:
