With the Magformers City Bus Set, a cute motorized bus travels over a layout of 11 ribbed road pieces and stays on course thanks to a clever on/off locking mechanism. This can be easily deactivated with a click of the free play switch, allowing the bus to roll independently over flat surfaces, enabling children to play with the set alone or with their collectible characters. A cool stop-go barrier automatically brings the bus to a halt, and as soon as you lift it, the bus continues its journey through the Magformers city. A bridge piece enhances the play value for children, making the City Bus Set the centerpiece of any cityscape they create with Magformers magnetic pieces or other building blocks.
