How thick the tubing is will depend on which frame member it is, and what price point the bike inhabits.
The chain stays and seat stays will always be thicker walled than the main triangle, and a less expensive, recreational bike, like the Langster, will have thicker walled tubing than a high -performance bike like the Allez Sprint or a CAAD-13
either way, I echo the sentiment that bicycles are far more robust than they’re often given credit for around here
