An electric assist system usable for an electric assist bicycle includes an electric motor that generates assist power assisting human power of a rider of the electric assist bicycle, a rotation sensor that outputs a signal in accordance with a rotation of a rotatable component that rotates to operate the electric assist bicycle, an acceleration sensor that outputs a signal in accordance with an acceleration of the electric assist bicycle in a traveling direction thereof, and a controller that calculates a speed of the electric assist bicycle based on an output signal of the rotation sensor and an output signal of the acceleration sensor.

Disclosed is a system for controlling Classes of an eBike. The eBike having a motor and a motor controller. The system includes a server, a dashboard and an input unit. The server stores Classes instructions to operate the eBike in one of the one or more Classes. The dashboard includes a memory unit for storing motor instructions, a processing unit for processing the stored motor instructions to operate the motor under the instructions from the server, a display unit for displaying the processed instructions and the Classes instructions, and a bi-directional communication unit to communicate with the server. The input unit wirelessly communicates with the server. The Classes instructions includes a Classes display module to display the one or more Classes and a Classes module for allowing a user to select one of the one or more Classes via the input unit. The processed motor instructions are communicated to the motor via the motor controller to ride the eBike in the selected Class.

A method for regulating vehicle access comprises receiving, from an electronic device of a user, a request to access a vehicle. The vehicle can be disposed at a designated geographic location. Next, geographic information of the user is received from the electronic device. The geographic information is determined with the aid of the electronic device of the user. The user is then provided access to the vehicle if, based on the received geographic information, a geographic location of the user is within a given distance from the designated geographic location of the vehicle.

A bicycle sensor device of the type not having Internet accessibility and comprising at least one sensor element adapted for registering data regarding the bicycle, a data storage unit adapted for storing registered data regarding the bicycle, a processor element adapted for generating an output of the sensor device, and a transmitter element adapted for transmitting by short range communication an output of the sensor device to an external device being adapted for displaying the output of the sensor device to a user. The processor element is configured to cause the transmitter element to transmit the output of the sensor device to an external device in one of a first mode, a second mode and a third mode. The first mode is a normal operation mode, the second mode is a service request mode, and the third mode is a data transfer mode.

An operating device for a bicycle is disclosed. The operating device includes a display ring and a coaxially arranged operating ring arranged to rotate relative to the display ring. The display ring includes a display for displaying information and a first magnetic element that cooperates with a second magnetic element arranged on or in the operating ring. In a first position of the operating ring relative to the display ring, the first magnetic element is proximate to the second magnetic element, and if the operating ring is rotated away from the first position, the first magnetic element and the second element magnetically cooperate to bias the operating ring back to the first position. The display ring further includes a sensor that receives a signal when in proximity of a signal providing element.

Provided are a bicycle control system and a user verification method thereof, including a sensing module and a control module installed on a bicycle. The sensing module obtains a torque signal and an angle signal from a crank sensing component, further obtains a speed signal from a speed sensing unit, and outputs the torque signal, the angle signal, and the speed signal to the control module; the control module assembles the torque signal, the angle signal, and the speed signal into a signal sequence as a key to verify a user identity for the bicycle.
