Crossover Flywheel

technique where one changes direction while gaining or maintaining speed).

Though it has been attempted a few times, the first Crossover Skating Treadmill on which someone successfully and comfortably skated was developed in Bloomington, Minnesota in 2003. It was actually assembled in Roseville, Minnesota in March of that year. The first Crossover Flywheel had a fixed angle and was entirely human powered making it even more challenging than today's hydraulic and electric powered models.

As it says in the KARE 11 TV news article on the Crossover Flywheel (link "3" below), "It's part science, part sports". In physics terms, the lateral lean angle provided by the Crossover Flywheel is present for the specific purpose of simulating non-inertial reference frame conditions (a "non-inertial reference frame" is an accelerating reference frame, in this case accelerating laterally) in an inertial reference frame (or inertial frame of reference). That purpose in and of itself is quite a unique as the Crossover Flywheel may be the only device in the world that incorporates a lean angle specifically to simulate conditions seen under acceleration, though there may be others (in a centrifuge of the type that humans use for G-Force training, accelerations seen in a variety of "real world" situations are simulated in a situation).
