ABSTRACT:
A child's tricycle comprising a pair of rear wheels, a front wheel, a seat positioned between the front and rear wheels, a support for the seat extending between the front and rear wheels, a handle for steering, and a steering fork having an upper end for supporting the handle and a bifurcated lower end for supporting the front wheel. A one-piece crank extends through the front wheel and defines outer ends disposed on opposite sides of the front wheel for holding pedals whereby a child can propel the tricycle by applying foot pressure to the pedals to thereby turn the crank and associated front wheel. A driving connection between the crank and front wheel is provided by a centrally located bend in the crank, and a centrally located opening defined by the front wheel snugly receiving the bend. A head tube is eliminated by using a steering fork and steering wheel telescoping combination which extends through vertically-aligned openings in the tubular support extending longitudinally of the tricycle. The rear step is formed by a tubular housing which includes end plugs supporting rear axle bearings while also having flanges serving as a safety barrier between the step and adjacent rear wheels.
