StreetStrider: Difference between revisions

The '''StreetStrider''' is a mobile [[elliptical trainer]] invented by David W. Kraus, PhD,<ref>[http://www.soph.uab.edu/ehs/directory?facname=3413 David W. Kraus, PhD]</ref><ref>UAB Reporter, [http://main.uab.edu/Sites/reporter/articles/60626/ Kraus Takes Indoor Exercise Machine to Road], 19 March 2009</ref> former Associate Professor of Biology and Environmental Health Sciences at the [[University of Alabama at Birmingham]].

The StreetStrider consists of a T-shaped lower frame to which two front wheels and a rear wheel containing a drive assembly are attached, and an upright frame to which two reciprocating arm levers are attached. Two elongated foot platforms on either side of the lower frame are attached to [[crank (mechanism)|cranks]] as part of the drive assembly, which, as with [[bicycle drivetrain systems]], also includes a hub, a rotating axle, and an internal [[hub gear]] system translating the axle rotation to the hub. The StreetStrider drive assembly is either chained or chainless direct drive, depending on model. The lower end of each arm lever is attached to the front end of each foot platform, which, by connection in the rear to the rotating crank arm and in the front to the pivoting arm lever, moves generally in an elliptical path. The device also includes a leaning mechanism for steering, as well as brakes and multiple gearing.
