Hmm...

Somehow I doubt that this burns a million calories (1000 kcal) an hour, even though it says so on the official site. That's 500 times the healthy daily intake of energy. --Alx xlA 02:34, 10 July 2007 (UTC)

I think you are getting confused. There are 2 (I want to say units of energy, but I don't remember if that is right) measurements called a calorie. There is calorie (with a little c) and Calorie (with a big C). What we eat (and is on food package labels in the US) are big C Calories. 1000c = 1C. From what I know, this is only a problem in the US...the rest of the world uses kcal instead of Calorie. For a better explanation, read the Wikipedia article on calorie —Preceding unsigned comment added by 71.207.131.68 (talk) 10:00, 31 August 2007 (UTC)

"Physics"

I've put this here until a source can be found. Not even the Trikke site makes these claims, as far as I can see. -AndrewDressel (talk) 02:54, 31 May 2013 (UTC)

The key physics at work when riding a Trikke is the conservation of anglar momentum. This physics concept explains the acceleration of a rotating system (increase in angular velocity) when the mass of the system moves toward the axis of rotation (reducing the 'mass moment of inertia' or the resistance to rotational accelaration). This is the concept that explains how an ice skater spins faster when they pull their arms in toward their body. As a Trikke rider carves in one direction, they create a rotational system. The movement of bodyweight toward the direction of the carve therefore moves the weight of the system toward the axis of rotation. A careful study of the rotational speed of the front wheel will show it accelerating as the rider carves, then decelerating as the rider straightens up for the next carve. This motion is often simplified as 'shifting your bodyweight side to side', but in reality it is moving the mass of the system toward center of the alternating axes of rotation.
