A combined engine and pedal-powered multipassenger, multipurpose four-wheel vehicle constructed by operatively connecting any two compatibly configured, commercially available bicycles and powering at least one of its four wheels with auxiliary propulsion apparatus for optional power assist of such vehicle. The two bicycles are operatively interconnected into side by side, spaced apart and aligned relationship by plural, specifically configured members, each bent to form a longer mid-portion and two shorter end-portions; each mid-portion positioned substantially horizontally and transversely between the two bicycles and each shorter end-portion operatively attached to correspondingly positioned frame members of the two bicycles at two spaced-apart points. A steering assembly based on modified trapezium linkage principle of king-pin with track-arm and track-rod connection of the front wheels of the two bicycles to provided efficient steering from either bicycle. An auxiliary propulsion apparatus to drive at least one wheel of the vehicle provides a choice of usual pedal-power alone, auxiliary power alone, or any combination of the two. Variety of auxiliary accessories interchangeably attachable to the interconnecting members enable the vehicle to transport additional passengers and assorted cargo in varied combinations of them. All operating controls of the two bicycles and the auxiliary power assist apparatus are combined for operative control by one person. All protective attachments and obligatory accessories required for safe, legal operation of thus constructed vehicle over public streets and roads are effectively incorporated.
