UGears The Knight Bus Transforming Wooden Model — Spring-Driven Harry Potter™ Bus

A transforming wooden model bus from the UGears Harry Potter™ collection. Press the magical manipulator button to launch the bus: a spring-driven gear system (including a flip gear) transfers energy to the wheels and lets the bus coast. The bus can change width with a twist of the top knob—twist counterclockwise to narrow and clockwise to expand—and the width change also alters the bus’s speed (normal width runs fast; compressed runs in slow motion). Kit details: 268 pieces, rated Medium difficulty, estimated assembly time 6 hours. The kit assembles without glue; sandpaper and wax are included. Detailed illustrated instructions are available in 11 languages.
