ISO 20957-10:2017 specifies safety requirements for exercise bicycles with a fixed wheel or without freewheel that have an inertia of >0,6 kg·m2. The requirements are in addition to the general safety requirements of ISO 20957-1, with which ISO 20957-10:2017 is intended to be read in conjunction.
Any attachment provided with the exercise bicycle with a fixed wheel or without freewheel for the performance of additional exercises is subject to the requirements of ISO 20957-1.
