Guys started building custom choppermotorcycles in the United States in the mid-1960s. The most extreme of all custom styles, often using radically modified steering angles and lengthened forks for a stretched-out appearance.
In the early 70s I put Ape Hanger handlebars on my old pedal bike and felt as cool as the guy on our shirt.
