Scales.
With electronic scales

No, the plane would weigh the same.
Yes, bobtails are required to cross open scales and ports of entry, all the same.
stick it on some scales
Which of scales are better - jennings or American Weigh? Thank you
A scale, rated in kilos or possibly pounds. One of those used to weigh luggage when travelling by plane would be fine. Or use a regular set of bathroom scales. Lift the bike, get on the scales, Note the number. Put bike down, note the number. Subtract 2nd number from the 1st number, and that's your bicycle weight.
You don't. Check the scales.
because it has scales
Unfortunately there were no scales to weigh them.
If they can stand, just pop them on the scales as you would weigh yourself.
