1. A biomechanical diagnostic machine for fitting a bicycle frame for a bicycle rider, comprising:
- a frame for supporting a bicycle rider, said frame comprising three contact points for a bicycle rider, comprising a bicycle saddle, bicycle pedals, and bicycle handlebars;
a bicycle saddle attached to said frame, configured to support said rider in a riding position;
a seat tube with a first end and a second end, with said first end pivotally attached to said frame at a pivot attached to said frame adjacent to said bicycle saddle, and attached to a bottom bracket at said second end, said seat tube configured to telescope in or out to increase or decrease the distance between said pivot and said bottom bracket, with said seat tube configured to pivot in the plane of said frame to change the angle of the seat tube relative to horizontal, with said telescoping motion powered by at least one linear actuator and said pivoting motion powered by one or more linear actuators, with said linear actuators controlled from a control console;
a drive train rotatably mounted in said bottom bracket and comprising an axle with a left and right pedal attached, with said axle configured for rotation in said bottom bracket;
a load attached to said drive train, for providing resistance to said axle rotation; and
a handlebar assembly attached to said frame, comprising a bicycle handlebar, and vertical and horizontal adjustment assembly each powered by one or more linear actuators, with said linear actuators controlled from said control console;
wherein said biomechanical diagnostic machine is configured for adjustment of handlebar drop and reach, angle of said seat tube, and distance between said saddle and said bottom bracket.

Abstract
Presented is a bike fitting and diagnostic machine with adjustable rider contact points of the saddle, the pedals, and the handlebars. Adjustments can be made while the rider pedals, and while the rider'"'"'s output is measured in watts, calories, heart rate, or other units. Optimal bike fit parameters are determined to help a rider select a well fitting bike or have one made to his specifications.
