The Matterhorn or Flying Bobs, sometimes also known by alternate names such as Musik Express in the UK is an Amusement Ride very similar to the Superbob, which consist of a number of cars attached to axels and swing out and in. The hill and valley shape of the ride makes the swinging motion more violent, the faster the ride goes, the more violent the swinging motion. It is quite common to see this ride at a travelling Fun Fair.
