The invention relates to a method for deterring theft of a vehicle having a three-phase electric motor without a freewheel (10), comprising the steps of using the motor in a generator mode to power a motor control circuit (14) in an initial phase of rotating the motor through motion of the vehicle; and, when the power supply level of the control circuit reaches a first threshold (Vmin), connecting by the control circuit first and second phases (b, c) of the three-phase motor continuously to a first power supply line (Vss), whereby the first and second phases are short-circuited and cause an increased braking force of the motor. During this time, the third phase of the motor may be connected to continue to supply energy to the control circuit.

A transmission for a motorcycle includes a housing; at least one shaft at least partially accommodated in the housing, a locking device which has at least one first locking element which can be rotated with the shaft and at least one second locking element which can be moved relative to the housing, relative to the shaft, and relative to the first locking element. The second locking element can move between at least one release position in which the locking elements do not engage in one another and the shaft is released for rotation, and at least one locking position in which the locking elements engage in one another to secure the shaft against rotation relative to the housing. The transmission further includes an actuating device configured to move the second locking element out of the release position into the locking position via at least one intermediate position.

A system having a motorcycle and a transportable radio device. The motorcycle has a frame with a steering head bearing seat and a drive unit, and a switch unit and a control device. The control device has wireless communication with the radio device for controlling operating modes of the motorcycle, depending on an authentication information transmitted from the radio device to the control device. The control device is configured for wireless transmission to the radio device of a blocking information which shifts the radio device into a sleep mode, in which mode communication of the radio device to the control device ceases. The control device also is configured for wireless transmission of a first and/or second piece of time interval information relating to the length of a first and/or second time interval to the radio device, at the end of which the radio device is shifted into the sleep mode.

A control unit (40A) includes an operation state determination unit (43) that determines an operating state of a driving source (21) and a communication state determination unit (46) that determines a communication state between an authentication unit (2) and a remote key (4), and the control unit (40A) disables a starting of the driving source (21) by a driving source starting unit (21a) when the control unit (40A) is in an ON state, the operation state determination unit (43) determines that the driving source (21) is in a non-operating state, and the communication state determination unit (46) determines that communication with the remote key (4) is lost.

The present invention relates to a bicycle with bicycle alarm. The bicycle includes a control unit for functional interaction with at least one subsystem of the bicycle. The control unit includes processing means, such as including a processing unit, for processing the at least one status signal, and output means for outputting at least one output signal. The bicycle further includes the at least one subsystem being arranged for providing at least one alarm status signal relating to the bicycle alarm as the at least one status signal, and the processing means are arranged for processing of the alarm status signal relating to the bicycle alarm and providing at least an alarm output signal as the at least one output signal. The alarm output signal is a signal for providing an alarm signal for an audible alarm, an alarm signal for a visible alarm and/or an alarm signal for distribution via a network connection, such as a network connection for short-range, a network connection for a local range, or a network connection via a cellular or mobile network.
