According to one aspect of the present disclosure, a rotor includes a plurality of permanent magnets and a support supporting the permanent magnet. The support includes at least one of an outside support fixed to a radial outside of the outer cores to circumferentially support an end face of the permanent magnet from both sides and an inside support fixed to a radial inside of the outer cores to circumferentially support the end face of the permanent magnet from both sides. Each of the outer cores includes an opposite face parallelly opposed to the end face of the permanent magnet in the circumferential direction. The outside support and the inside support each includes a support face circumferentially supporting the end face. The support face is disposed on a side closer to a center line of the permanent magnet than the opposite face in the circumferential direction.

A method for monitoring the travel speed of a bicycle, in particular a pedelec. The method includes: providing a power supply for a speed signal transmitter, ascertaining a first speed for the bicycle, interrupting the power supply for the speed signal transmitter for a specifiable interruption time span, while the power supply is switched off, ascertaining a second speed, ascertaining a comparison result by comparing the ascertained first and second speed, and recognizing a faulty speed signal transmitter as a function of the result of the comparison.

A bicycle braking system includes a server, a portable device such as a smartphone, a display unit, a control unit, a power supply unit, a rotating electrical machine, and a bicycle. The portable device includes an image display unit, a braking condition transmitting unit, and a braking condition setting unit. The control unit regeneratively brakes the bicycle using the rotating electrical machine in accordance with the braking condition set by the braking condition setting unit. The braking system enables a non-user to set braking conditions for the bicycle and to perform braking based on the conditions set by the non-user.
