Pedalling efficiency indicator
First Claim
1. For a pedacycle of the type including a crankset being rotatably mounted in said pedacycle and defining an axis, said crankset having a crank arm generally extending radially from said axis and a pedal being rotatably mounted to a distal end of said crank arm and extending axially outwardly from said crank arm, a pedalling efficiency indicator comprising:
- means for measuring a first force being normal to a selected one of said crank arm and said pedal and being in a plane perpendicular to said axis, and further for measuring a second force being tangential to said selected one of said crank arm and said pedal; and
means for computing pedalling efficiency as a function of said first force and said second force.

Abstract
A pedalling efficiency indicator measures the forces acting on the crank arm of a pedacycle to compute pedalling efficiency as a function of these forces. Generally, pedalling efficiency is computed as the ratio of the normal component of force acting on the crank arm to the resultant load of the crank arm. The computation of pedalling efficiency may then be visually indicated so that the pedacyclist may use a pedalling technique to maximize efficiency.
