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.

Various electric scooters are disclosed that include a battery receptacle configured to releasably retain a rechargeable battery therein. The electric scooter may include a deck and a strut extending between the deck and a rotatable shaft connected to a handlebar assembly. The battery receptacle may be supported by the strut, and the battery may be insertable into and removed from the battery receptacle through translation of the battery in a direction substantially parallel to a longitudinal axis of the strut. The battery may be configured for use in a power tool in addition to the electric scooter.

Various personal mobility vehicles, such as scooters, are disclosed. The scooter can include at least one battery and motor for powering at least one driven wheel. The vehicle can include a gear assembly to convert a torque produced by the motor to a different torque to a driven shaft to power the at least one driven wheel. The battery can be removable.

An electric bike having an improved effect of heat dissipation has a body, a driving device, and a battery. The body has a frame, a rear wheel, and a front wheel, wherein the rear wheel and the front wheel are mounted to the frame. The driving device is mounted to the body and has a motor and a shell. The motor is connected with the frame and has a front end near the front wheel and a rear end near the rear wheel. The shell covers the motor and has multiple inlets and multiple outlets disposed therethrough. The multiple inlets are located near the front end of the motor. The multiple outlets are located near the rear end of the motor. The battery is electrically connected to the motor. The front wheel, the battery, the motor, and the rear wheel are serially aligned.

A battery attaching/detaching structure for a saddle-type vehicle including: a plurality of substantially rectangular parallelepiped batteries for supplying electric power to a power source of the saddle-type vehicle; a battery case in which the batteries are stored; battery-side terminals provided on lower surfaces of the batteries; and case-side terminals engaged with the battery-side terminals, comprises terminal holders that support the case-side terminals such that the case-side terminals are movable between a connected position where the case-side terminals are connected to the battery-side terminals and a retracted position where the case-side terminals are separated from the battery-side terminals. Between the case-side terminals and the terminal holders, springs for urging the case-side terminals in a direction of pressing the battery-side terminals are disposed. Such battery attaching/detaching structure is capable of limiting the movement of a stored battery and maintaining good electrical connection between a battery-side terminal and a case-side terminal.

A bicycle with removable battery for supplying power to electric components, comprising a frame composed of an upper tube connected with a front oblique tube and with a rear vertical tube, which in turn are connected in a lower region so as to form a seat for a bottom bracket and with which a pair of horizontal rear chainstays and a pair of oblique rear chainstays are coupled. The front oblique tube has an axial seat for a removable battery and for accommodating connection and/or electric power supply cables. The axial seat has an axis that passes above the bottom bracket and a lower end that is open and located at the interspace between the pair of horizontal rear chainstays.
