Rear-wheel drive cars that use an electric motor—or motors—to power the wheels typically use a rear-axle-mounted motor—or motors—to send power to the drive wheels via half-shafts.

Both the bicycle and the toy car have wheel and axle mechanisms that help them to move. So, how does this work? A wheel moves forward by rolling in a circle, using circular motion. Whoops!
