Abstract: A bicycle power sensing system includes an electronics module that can be separated from a power-measuring hub assembly. The power-measuring hub assembly includes onboard electronics that cooperates with the electronics module when the electronics module is attached to the power-measuring hub assembly. The onboard electronics includes a memory module that stores a calibration value for a torque tube of the power-measuring hub assembly so that the torque tube does not have to be recalibrated after the electronics module is removed from the power-measuring hub assembly.

Abstract: A torque sensing arrangement has a set of strain sensors, such as strain gauges, mounted to an adapter that can be mounted to a chain ring of the crank set of a bicycle wheel. The adapter may have an annular body that can be used to retrofit the original crank set of a bicycle to have torque sensing components without having to replace the chain rings or the crank arm of the crank set. Together with angular velocity measurements, the measurements of the strain sensors may be used to calculate the amount of work or power exerted by the cyclist to propel the bicycle.

Abstract: A carrier for securing a personal transporter to a motorized vehicle generally includes a base for engagement with the motorized vehicle and a transporter support movably engaged with the base for movement between a transport position and a loading position. The personal transporter includes a pair of wheels with a platform therebetween, and a stem extending upwardly from the platform. The transporter support includes a stem receiver and a platform support. The stem of the personal vehicle is releasably engaged with the stem receiver, and the platform is releasably secured to the platform support.

Abstract: A system for supporting the non-driven wheel of a bicycle, in which the driven wheel of the bicycle is engaged with a stationary bicycle trainer. The system contemplates a support member that is configured for engagement with a supporting surface, and which includes wheel engagement structure for supporting the non-driven wheel above the supporting surface. A pair of support members are engaged together in different orientations, to raise the elevation of the wheel engagement structure of the upper support member above the supporting surface and to enable the user to adjust the angle of the bicycle.
