In particular embodiments, a computing system may collect, for each ride of a plurality of rides, first ride data associated with a user riding a personal mobility vehicle during a certain time period. The system may calculate, for each ride, an approximate load on the personal mobility vehicle based on at least the first ride data. The system may calculate a user profile of the user based on the approximate loads. The system may collect, for a subsequent ride, second ride data associated with the user riding a current personal mobility vehicle after the certain time period. The system may calculate, for the subsequent ride, a second approximate load on the current personal mobility vehicle based on at least the second ride data. The system may compare the second approximate load to the user profile and classify the subsequent ride as individual or tandem based on the comparison.
