Fs. FtDT. Physics Analysis. Newton’s equations On Cyclist.

Mathematical Model. . Cyclist power, normalized by cyclist’s mass, cadence, and crank length Comes out to be: (Bicycle_Drivig_Force) / (Cyclist_Weight) [-].

Methods. Cyclist repeats two similar tests, With Pulling the handlebar and With-Out Pulling.

Methodology. Experiment 1 Tree Diagram. Standing Drops Hooks Hoods WG WOG WG WOG WG WOG.

Results. Average leverage 13.8 ± 3.9 %, max potential leverage 19% All data is from SRM ergometer Torque analysis sampling at 200Hz Δ – The difference of the measurements between With Grip (while pulling the handlebar) to With-Out Grip.

Applicability/Usage. Bicycle Fit Hand Handlebar Force (magnitude & Direction) Cycling Computer Sit Stand OUT PUT.
