The objective of the thesis was the design of the trailing arm of an electric scooter’s rear wheel in such a way that the installation of a GEM motors’ in-wheel motor would be allowed. The scooter’s existing chassis had been used and its points of attachment for the trailing arm were kept. The needed relevant geometry of the existing scooter was measured and a corresponding 3D model was designed. On the basis of the geometry, possible concepts of motor mounting and suspension have been searched. The possibility to install the in-wheel motor on single-sided trailing arm was checked. The most suitable concept was chosen with the desire for the suspension to become hidden. A detailed construction for the chosen concept was designed and a strength analysis for the trailing arm was made.
