Computerized method and system for fitting a bicycle to a cyclist

Abstract

This invention is an apparatus for quantitatively measuring the fit of an individual to one or more bicycles or other such human-powered conveyances. The apparatus comprises at least a three-dimensional marker tracking system, a software-based data analysis and presentation computer system, and (if necessary) a means of supporting a bicycle in a stationary location such that the individual being fit can pedal their bicycle in a normal yet stationary manner. In advanced embodiments, the system includes a means of simulating a bicycle, and perhaps even a means of altering the position of the bicycle components to perform a bicycle fit in a fully automated way.

Description

FIELD OF INVENTION [0001] This invention relates to an automated way of customizing and optimizing the fit of a bicycle (or other human powered conveyance) to a particular person. BACKGROUND [0002] Historically, most individuals who purchase a bicycle were steered toward a bicycle frame that appeared to be a good fit for their height and stature. Over time, many bicycle shop employees have become experienced at approximating what frame size will be a reasonable match. A bicycle can be chosen from off-the-shelf sizes that range from 13-26 inches. This is a measurement of the distance from the center of the pedal crank bearing (bottom bracket) at the bottom of the bicycle to top of the top tube that connects the saddle to the handlebars. Once a bicycle was chosen, the only refinements to the selected bike were typically limited to minor adjustments made to the height of the saddle. [0003] More recently, two options for bicycle fitting have become available. The first of these is a ful...

Benefits of technology

[0006] The purpose of the present invention is to perform a semi-automated, low cost, high accuracy bicycle fit for an individual. One objective of the invention is to determine the proper bicycle frame size and geometry for the individual who is purchasing a new bicycle, possibly from a database of geometries of available models. A second objective of the invention is to determine how to adjust a bicycle so that the bicycle-to-cyclist interface is optimized. A third objective of the system is to determine which components on a bicycle could be changed so that the bicycle-to-cyclist interface is optimized. A fourth objective of the system is to determine which components should be added to the bicycle or the cyclist, or deleted from the bicycle or the cyclist, so that the bicycle-to-cyclist interface is optimized. This optimization can be directed at riding comfort, riding endurance, riding performance, or some other target criterion.

Problems solved by technology

Once a bicycle was chosen, the only refinements to the selected bike were typically limited to minor adjustments made to the height of the saddle.

However, his methods and his system require experiential intuition and are at best only partly quantitative and automated.
