Nevertheless the payload of bicycles and the weight of the rider are not taken into account for the formulation of the test loads for mechanical tests. The average weight of bicycle users varies widely worldwide, and in recent years there has been a significant increase, especially in the industrialized nations, where electrically power assisted cycles in particular are experiencing very high demand. The influence of the rider's weight and driving style is determined by operating load measurements, based on the current fatigue tests the component damage ratio under variable amplitude loading is calculated in order to create a basis for a future reformulation.en0142-11232021e-bikeElectrically Power Assisted Cycles (EPAC)Fatigue testOperating loadsRider's weightJournal Article10.1016/j.ijfatigue.2021.106271Other
