Electric kick scooters’ popularity is constantly growing in the Europe. It is anticipated that sales of this type of solution will grow by approximately 25% per annum [1]. Conversely, these vehicles possess characteristics that impede their dissemination and utilisation for purposes other than their intended function as the final stage of a journey. These include, for example, their weight and size, which make them difficult to transport using traditional means of transport, their low range [2], and their limited ability to handle uneven terrain. Bearing this in mind, the Leonardo project (microvehicle fOr staNd-alone and shaReD mObility) developed an electric micro-vehicle that combined the features of a unicycle and a scooter. The main goal was to design a vehicle with a large front wheel suitable for rough surfaces [3] and achieve greater torque and range, while keeping the total weight below 10 kg. Reducing the weight of the entire solution to under 10 kg was an especially challenging task. To achieve this, the suspension elements were completely eliminated. A board took over the role of the shock absorber, providing adequate comfort while ensuring an appropriate level of durability. The following section of the paper outlines methods for determining operational loads and conducting multivariate optimisation analyses. These analyses allow for weight reduction and ensure that the structure meets functional requirements [4].
