Abstract
An electronic measuring system for bicycles comprising a user interface device allowing a user to select a pedalling arc, a power meter apparatus which is configured to measure at least one force exerted by the user during pedalling, when the pedal is moving in the pedalling arc, determine a measurement quantity associated with the force measured in the pedalling arc, and determine the user's performance data in the pedalling arc on the basis of the determined measurement quantity.
Claims22
An electronic measuring system configured to determine performance-data of a user relating to one or more pedal-strokes exercised by the user on a pedal of a bicycle,
- said bicycle is provided with two pedal-cranks designed to rotate around a rotation axis, and two pedals which are coupled to said respective two pedal-cranks so that each one describes a pedalling circumference during the complete rotation of the corresponding pedal-crank around said rotation axis, the electronic measuring system comprises:
- a user interface device which is configured to allow a user to set a pedalling-arc comprised in said pedalling circumference of said pedal wherein said pedalling arc does not have a predetermined fixed value, and provide a user-command containing said pedalling-arc set by the user, and
- a power meter apparatus which is configured to:
- be operationally connected to said user interface device to receive said user-command containing the pedalling-arc set by said user,
- measure at least one force exerted by the said user during pedalling, when the pedal is moving in the said pedalling-arc set by said user,
- determine at least one measurement quantity associated with said force measured in said pedalling-arc set by said user, and
- determine the performance data of said user in said pedalling-arc based on said determined measurement quantity.

A method for determining performance data of a user relating to the pedal-stroke exercised by the user on a pedal of a bicycle, said bicycle is provided with two pedal-cranks designed to rotate around a rotation axis, and two pedals which are coupled to said respective two pedal-cranks so that each one describes a pedalling circumference during the complete rotation of the corresponding pedal-crank around said rotation axis, the method comprises the steps of:
- setting, by means of a user interface device, a pedalling-arc comprised in said pedalling circumference wherein said pedalling arc does not have a predetermined fixed value and providing a user-command containing said set pedalling-arc,
- receiving, through said power meter apparatus, said user-command containing the pedalling-arc set by said user,
- measuring, by means of a power meter apparatus, at least one force exerted by the said user during pedalling, when the pedal is moving in a pedalling-arc set by said user,
- determining, by means of said power meter apparatus, at least one measurement quantity associated with said force measured when the pedal is moving in said set pedalling-arc, and
- determining, by means of said power meter apparatus, the performance data of said user in said pedalling-arc set by the user, based on said determined quantity.
