The term micromobility refers to small, low-speed vehicles intended for personal use, including bicycles, electric scooters (or e-scooters), and similar vehicles—whether powered or unpowered and both personally owned and deployed in shared fleets (as in bikesharing systems). SAE International developed a taxonomy of powered micromobility vehicles based on form factor (e.g. bicycle, standing or seated scooter) and physical characteristics such as width, curb weight, top speed, and power source [1]. The primary vehicle types deployed in shared fleets are human- or electric-powered bicycles in bikesharing, seated or standing e-scooters in scooter sharing, and mopeds.

Shared Micromobility - the shared use of a bicycle, scooter, or other low-speed mode - is an innovative transportation strategy that enables users short-term access to a transportation mode on an as-needed basis [2, Ch. 12]. Shared micromobility services may be docked (a station-to-station system in which users unlock vehicles from a fixed location, which also generally contains the IT infrastructure for reservation and payment, and in some cases facility for electric charging), dockless (with the IT infrastructure and locking mechanism integrated into the vehicles), or a hybrid of the two models [3].
