A portable, multi-platform friction drive system with a retractable motor drive assembly (12), containing all needed components of an electric friction drive system in a portable handheld case (10), including motor (18), batteries (34), and all associated electronics (36), as well as a mounting system (30) that enables use on popular bike share bicycles (20), personal bicycles, and kick scooters. Its mounting system (30) enables the friction drive system to be easily installed in seconds on many varieties of bicycles or kick scooters, and to be removed just as easily when no longer needed. And by means of its retractable motor assembly (12), the present invention enables the friction drive system to be as compact, clean, and safe as possible so as to be easily carried and stored when not in use.
