The Knight Bus™ can roar through the streets of Muggle London (or your living room) thanks to its powerful spring-powered motor, which is wound using a secret key stored on top of the bus. This bus can narrow and expand itself, and change speed when it does, just like in the movie Harry Potter and the Prisoner of Azkaban.

To set the bus in motion, press down the magical manipulator button while holding the bus, then let go! The Knight Bus™ roars off thanks to a system of gears that transfer energy from the spring to the wheels, including a "flip" gear that lets the bus continue coasting. Twist the knob on top of the bus counterclockwise and the bus becomes narrow, for squeezing between traffic. Twist the knob clockwise to expand the bus (and any passengers) to their true size. But here's the amazing thing—as the width of the bus changes, so does the speed! In its normal (not compressed) state, the bus travels astonishingly fast. Compress the bus and an internal mechanism makes the bus travel in slow motion.
