Kendee Distributing Company of Gardena, California was the US importer for a mini bike called the Dandy. One model was called the MR40, which referred to its 40cc 2-stroke engine. Here’s an example that’s said to be museum quality as it’s never been run.
The baby engine was good for 3 horsepower pushed through a single-speed transmission with a centrifugal clutch, and Kendee claimed that the 33 pound bike was capable of carrying 300 pounds. Top speed was 35 miles per hour.
