This DIY wooden mechanical model bus is an exciting addition to the Ugears Harry Potter™ collection, and a very clever piece of engineering indeed. 

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.
