"And he extended the front end and added ape hangers."

"Planet of the Ape Hangers" (Japanese version only)

These include handlebars with a very far reach, similar to ape hangers (see above) but mounted less vertically, and handlebars designed for under-seat steering, called Whatton bars.

They are often called "mini-apes" (miniature ape hangers), but a true buckhorn must be rounded on top, never with the sharp angles of a Z-bar on the top.

The term chopper started to be used from the late 1960s onwards, for motorcycles whose frames had been customized to have a greater angle at which the front suspension protruded, with smaller fuel tanks and tall handlebars called ape hangers.
