Quantitative Assessment of Pavement and Scooter Suspension on Ride Quality Electric scooters are becoming a common form of transportation in large cities and on college campuses. These shared dockless scooters are seen as a sustainable and environmentally friendly mode of transportation for commute and recreational trips. As these scooters are gaining popularity, rider comfort will be an important performance measure for scooter companies. This research uses data from a threeaxis accelerometer mounted on two scooter models  the MI M365 and Segway ES2  to compare ride quality on a series of multiuse paths with a variety of pavement. The test route was comprised of four pavement types  asphalt, concrete, brick pavers, and permeable pavement. Results indicate that the MI M365 with pneumatic tires provided superior ride quality on all pavement types than the Segway ES2 with solid tires. A ttest conducted to test this hypothesis also revealed that the results were significant. For the MI M365, the ride quality on the four pavement types was noticeably indifferent for 20% of the time. For the remaining time, the permeable pavement provided slightly better ride quality than other surfaces.

A Discussion of User Experience on a Panoramic Scooter Riding Video Service This paper compares the user experiences (UXs) while riding a scooter on the road to watching a panoramic scooter riding video. The aim of this study is to determine whether using a panoramic scooter riding video service produces positive UXs for the riding experience as riding on a real scooter. Data were collected from an experiment involving a total of 34 individual scooter commuters. The participants were asked to watch a panoramic scooter riding video and to complete a user experience questionnaire (UEQ). The results verified that using the panoramic scooter riding video service may not be able to create scooter riding experiences for users. In order to enable widespread use of panoramic scooter riding video service in real life applications, a number of suggestions are proposed for the design of related services to strengthen the advantages of panoramic scooter riding video in simulated twowheeler ride experiences.
