Got it. I’d say that definitely sounds like a 2 person job to balance it while lifting: I wouldn’t want the risk of that much weight falling on me (or the risk of damage to the bike from the momentum of that much weight falling if it falls to the other side rather than on me).
But: if you have a second person to help with the procedure, might it not be simpler to just have that second person help you get it on the stand without using the floor jack at all? 67lbs is pretty heavy to try to lift by oneself, at least given the position that one person would be trying to lift it from; but for two people, 33-ish lbs each - one lifting from the front and the other from the rear and using your legs to do most of the actual lifting work - should be doable for most people, I’d think (putting aside any pre-existing disabilities or infirmities, of course).
Also: it’s been a while since I’ve used my floor jack, but I think you might be in for more bouncing/instability of the bike while lifting than you might be picturing. With a car, you don’t have that issue because there are thousands of pounds resting on the jack as you’re lifting it; but remember that it’ll take many pumps of the jack’s lever arm to get the bike up to the height you want, and 67lbs balanced somewhat precariously on the lift point likely won’t be enough to dampen the bouncing from pumping the lever arm up and down.
Oh, also: most jack stands that I’ve used have wheels that don’t lock. So you’d have to chock the wheels somehow to keep it from moving while you’re pumping the arm to lift the bike.
The more I think about it, the more I don’t like it.
Got any strong neighbors/neighborhood teenagers that’ll just lift that sucker on and off of the stand for you?
