A monkey bike is a highly compact, small-displacement motorcycle characterized by tiny wheels, a low seat height, and fold-down handlebars. The name originated from the Honda Z series because adult riders looked disproportionately large and hunched over like monkeys when riding them. They are popular as pit bikes, recreational vehicles, and highly customized urban runabouts.
Heard on the job
We strapped the monkey bike to the back of the RV so we have something to ride around the paddock.
