Fahrender Ritter

This wooden mechanical DIY bus model is an exciting addition to the Harry Potter™ collection from Ugears and a real engineering masterpiece.

To set the bus in motion, hold it firmly and push down on the magical manipulator button. Then release it and the Driving KnightTM thunders away thanks to its gear system, which transfers the energy of the spring to the wheels. The "tilt" gear wheel allows the bus to roll on while idling.

But the most important feature of the Driving Knight™ model kit is its ability to change its dimensions, i.e. become narrower or wider, with a turn of the magic manipulator. Turn the knob on the roof of the bus anti-clockwise to make the bus narrower to weave through traffic. Turn the knob clockwise to widen it (and all passengers) back to its original size. But there's something else special - when the width of the bus changes, its speed changes too! In its normal (non-compressed) state, the bus goes incredibly fast. When you make the bus narrower, an internal mechanism makes the bus move in slow motion.
