Nowadays, scooters represent a popular transport mean. They are used not only by young people, but also by middle generation people. This transport mean allows to move in cities and towns in a comfort way. Scooters can have various design depending on the price and required application. Recently, scooters with own source of power are widespread. These scooters required to the designed properly regarding to safety, reliability and comfort during their operation. The presented work is aimed at an engineering design of a scooter, especially at a de-sign of its main-bearing frame. The scooter is designed in a 3D modelling soft-ware environment. As the scooter frame is exposed to the loads during the operation, its structure is analyzed from the strength point of view. The analyses are performed by means of the finite element method. The 3D model of the scooter and the strength analyses have been carried out by means of commercial software. The research presented research shows the loads acting on a scooter frame structure during the operation, introduces the boundary conditions defined for calculations and reveals the results of the performed simulation calculations.
