Engineering for Bikes (EFBe) performed frame tests on a variety of different bike frames to see how "strong" (in laymans terms) they are. ... The test applies 268 pounds of force to the cranks for 100,000 cycles, and then 291 pounds for another 100,000 cycles. ... Their test fixture caused failures in nine of fourteen frames tested. ... However, when the force falls below a certain threshold, called the endurance limit, you can repeat the application of force forever, with no failure. ...
