The Knight BusTM from the Harry Potter series is here to rescue young wizards, witches and Muggles alike. 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 create this triple-decker bus, with its unique features from the Wizarding World universe, our Ugears designers and engineers set themselves an ambitious goal: create a bus that can narrow and expand itself, and change speed when it does, just like in the movie Harry Potter and the Prisoner of Azkaban.
The speedy Knight BusTM 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. Raise the magical manipulator button, also on the roof of the bus, to lock the drive gears and prevent the bus from running away before all wizards and witches have boarded. With the bus stopped you can now remove the secret winding key, insert it into the ratchet mechanism on the side of the bus and give it a few twists. To set the bus in motion, press down the magical manipulator button while holding the bus, then let go! The Knight BusTM 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.
