The method involves a step of measurement of a bearing force (Fp.sub.n) on a pedal (1) of the pedal set (4), different from the useful effort, exerted by the individual during a pedalling cycle, a step of determination of a maximum (max(Fp.sub.n)) of the bearing force measured during the pedalling cycle (CF.sub.j), and a step of estimation of a mean useful effort exerted by the individual during said pedalling cycle from the maximum of the bearing force determined and with the aid of a predetermined correlation function between a maximum bearing force during a pedalling cycle and a mean useful effort in said cycle.

An e-bike interface is a hybrid wired/wireless e-bike control system that integrates wireless bicycle components into operation of an e-bike. The e-bike interface provides a frame-mounted control and display that is wired to, for example, an assist motor and a battery, and provides a wireless communication bridge between wireless bicycle components and corresponding wireless controls located on a handlebar.

A motorcycle which provides multi-purpose high-agility hybrid power having an integrated rear-wheel structure in which a tire is mounted on an outer wheel is disclosed. An electric motor and a one-way clutch are mounted on an inner wheel. The motorcycle provides a plug-in mode and provides automatic power conversion to reduce the overload of the electric motor in an automatic driving mode.
