Boys Build “Pumpmobile” (Mar, 1938)

Boys Build “Pumpmobile”
TWO young inventors in Dobbs Ferry, N. Y., combined their resources, consisting of half of a bicycle and a four-wheeled coaster wagon, to produce a novel vehicle which they call a “pumpmobile.” The fork of the bicycle was mounted on the rear of the coaster wagon, locomotion for the combination vehicle being secured by pedaling the bike’s one wheel.
