Example: An exercise bike that can support 250 lb. Does the engineer find a large enough weight that deforms the bike, then take a fraction of that as the amount it can support?

That is knows as the Calvin’s Dad method (drive heavy trucks over a bridge until it collapses then rebuild it). No, engineers do not use that method. Well geotechnical engineers sometimes do, especially for pile load tests, but we all make fun of them. Silly soil guys and their nonhomogeneous semi-infinite half-space.
There is an ASTM code for design of exercise equipment that determines allowable user weight.
