Discussion

Analysis reveals structural dynamics impact design and functionality in e-bike drive units, suggesting optimisation opportunities.

Structural dynamics improve design and user experience in e-bike drive units, enhancing durability.
Resonance frequency analysis indicates load-dependent dynamics influence up to 10 kHz, guiding engineering approaches.
Multibody approach allows detailed modeling of mass and moment of inertia in e-bike systems, validating with experiments.
Findings suggest that structural modes significantly affect e-bike performance, highlighting the need for further study on multibody systems.

Steinbach et al. (2025) studied this question.
