Passenger cabin for cargo bicycle

A cargo bicycle having at least a frame, rear wheel, and rear carrier rack, comprising a rear safety cage, pair of footboards and passenger cabin having a canopy and box is provided. The rear safety cage is mounted to the frame. The passenger cabin is mounted to the rear safety cage, rear carrier rack and pair of footboards and forms an interior passenger space for accommodating passengers and protecting passengers from natural or human-made environmental elements. The canopy forms an upper interior space. The box forms a lower interior space and a pair of lower interior side spaces extending outwardly from the lower interior space, straddling the rear wheel. Each of the pair of lower interior side spaces is a self-contained vessel, further protecting lower extremities of passengers from components of the cargo bicycle and debris during operation of the cargo bicycle.
