Are tadpoles very fragile because of their geometry then? I'd
guess frames on bicycles (upstraight and bent) often last decades
and hundreds of thousands of kilos....

The loadings on bicycle frames transmitted through the wheels are
primarily vertical. On a trike, significant torsion forces are
transmitted through the frame.
