Been there, tried it.
It under weighs.
Why do you think that is? If you placed the non-measured wheel at equal height and just supported the bike from falling over to the side, this should work very accurately. Provided that your bathroom scale is accurate, of course. They operate in pretty much the exact range we need for one wheel.
