A Roller Racer, or Flying Turtle as it was originally named by the inventor, is a toy human-powered vehicle for children.
It was invented in the 1970s by a retired Boeing engineer as a gift for his grandson, using a tractor seat for the prototype toy.
[1] The vehicle consists of an injection-molded, polyethylene seat with rear wheels, attached to a T-style handlebar by a pin joint.
In the 1980s the Roller Racer was sold under the WHAM-O brand name Dragonfire,[2] but has been manufactured by Mason Corporation of Brentwood, Tennessee, US, since January 1987 .
Published studies in Experimental Non-Linear Physics have been conducted worldwide on this product.
