In 1949 Tony Anthony began selling his invention, the Convert-O Bike, under Anthony Brother's Refrigeration Co. The design was simple. It allowed for users to convert the tricycle to a bicycle when they thought they were ready for the two wheeler. Why throw away the tricycle when you upgrade to two wheels. Instead they would simply remove the rear axle, remove one of the rear wheels, and fit it to the rear of the frame. And it is now a 2 wheel bike. How cool is that?? This Convert-O Bike is built totally in alloy, ensuring it will stand the test of time. This little beauty is fully functional. Ready for the kids or grandkids.
