Bobsled roller coasters do not have a fixed track. The train travels freely through a trough. Bobsled coasters can not reach incredible speeds, because if it does, the car will fly off the trough. Thus, Bobsled coasters are relatively small.

The first real Bobsled roller coasters were built in the 1930s and 1940s and were made out of wood. These were known as Flying Turns coasters. None of these remain, with the last being Bobsled at Coney Island, demolished in 1974.

In the late 1980s and 90s, Mack Rides and Intamin AG manufactured many Bobsled coasters.

Long after the last wooden Bobsled coaster was demolished, Knoebels Amusement Park are to open the first modern wooden Flying Turns coaster, Flying Turns. It was originally planned to open in 2007 but was delayed due to dysfunctional wheels.
