The availability of electric energy onboard e-bikes allows the emergence of active safety systems like antilock braking systems (ABS). This paper presents the development of a test-bench that can be leveraged to validate an e-bike ABS for multiple bicycle geometry, loading and test scenarios. The approach consists in reproducing the dynamics of an e-bike thanks to a simulation model and interfacing it with a physical brake and the ABS hardware under test. The results and useability of the obtained hardware-in-the-loop (HiL) test-bench are discussed.
