Suspended Family Coaster

A Suspended Family Coaster is a steel inverted roller coaster built by Vekoma designed for families with no inversions. Just like all inverted roller coasters the train runs under the track with the seats directly attached to the wheel carriage. This latter attribute is what sets it apart from the older suspended swinging coaster, which runs under the track, but "swings" via a pivoting bar attached to the wheel carriage.
History.
The Suspended Family Coaster debuted in 2001 with the Rugrats Runaway Reptar opening at Kings Island in Ohio, USA, and Silver Streak at sister park Canada's Wonderland. Several clones and variations have opened since.
The original designs featured trains with a safety system consisting of over-the-shoulder restraints. These restraints would lock into place with a belt-type connector which would be attached the seat base. All of the original track designs were of the 342m model with concrete footers. 
In March 2007, Vekoma debuted a new version of the Suspended Family Coaster, the 294m model. The first installation of this was Jimmy Neutron's Atomic Flyer at Movie Park Germany. The ride differs from previous Suspended Family Coasters because it has a portable base-frame beneath the track rather than concrete footers and features a new train style with fully padded seats that utilize lap bar restraints.
One month later in April 2007, the 395m model was launched at Gröna Lund in Sweden. The ride, which was named Kvasten, features the same redesigned trains as Jimmy Neutron's Atomic Flyer. The ride also features a larger layout with a peak height of and a length of .
Models.
All models have one train, which has 10 cars with 2 seats on each car. This caters for up to 650 riders per hour. All of the models feature lift hills powered by tires and magnetic brake runs.
