...is not a bowl of chocolate chip cookies. They're pretty heavy...
I'm sure it's listed on their site somewhere, but I can tell you that raising and lowering it on any regular basis is not a bowl of chocolate chip cookies. They're pretty heavy and awkward.
What's you height limitation?
Well, maybe someone will give you an exact measurement, and being in Japan at the moment, rather than at home, I can do little more than guesstamate, but I doubt that the BX ROPS when folded would be higher than 72 inches, and more likely less than 66 inches.
As asked above, what is your height limitation?
