Abstract
Abstract A tricycle apparatus utilizes a chassis having a housing disposed surrounding the midregions of the rear axle of the tricycle. Each rear wheel is provided having a child carrying seat secured to a fender-like covering therefor. The rear axle is provided having two portions concentrically aligned with one another and each being locked to each other utilizing a removeable locking pin therefor. In a manual mode of operation, both portions of the rear axle, when locked together, are caused to rotate, operating the rear wheels by the conventional pair of bicycle pedals journaled to the tricycle frame. A double output shafted gear head motor, utilizing a pair of slip clutches is coupled individually to each portion of the rear axle so as to enable a battery, carried by the housing, to operate the motor, provided operating power for the tricycle when such motor, slip clutches and battery are added to a mounting within the housing.
