A bicycle control device includes an electronic controller that controls a motor to assist propulsion of a bicycle. The electronic controller is configured to decrease an output of the motor upon determining that a shifting device is performing a shifting action to change a transmission ratio of the bicycle. The electronic controller is further configured to end the control that decreases the output of the motor before a predetermined period elapses upon determining that the shifting action is completed or the transmission ratio is changed before the predetermined period has elapsed. The electronic controller is further configured to end the control that decreases the output of the motor upon determining that the predetermined period has elapsed in a case where the shifting action or the change in the transmission ratio is uncompleted even though the predetermined period has elapsed.

Embodiments disclosed herein include an electric assist bicycle adapted for a both personal and public use, and subcomponents of the bicycle. The electric assist bicycle can include a hollow frame with one or more cables routed within the hollow frame. The hollow frame can be configured with an internal battery compartment. The electric assist bicycle can further include a modular electronic locking system.

An electronic device can be mounted at least partly in a frame of a bicycle and used to monitor operations or properties of the bicycle or one or more components associated with the bicycle. The electronic device may integrate and communicate with a variety of components including sensors to facilitate customization of monitoring by the electronic device. The electronic device can have a relatively minimalist design. The electronic device, in some embodiments, may include a display that does not present alphanumeric characters to an operator, and the display may instead include multiple indicators that individually or in combination present information to the operator, such as the level of charge of one or more batteries or an operating mode of the electronic device or bicycle.

A vehicle has a frame, at least two wheels, a motor, a straddle seat defining a driver seat portion and a passenger seat portion at least partially rearward of the driver seat portion, left and right passenger footrests connected to the frame, the left and right passenger footrests each being movable between a stowed position and a deployed position, a passenger footrest position sensor for sensing a position of at least one of the left and right passenger footrests, and an electronic stability system electronically connected to the passenger footrest position sensor for receiving a signal from the passenger footrest position sensor indicative of the position of the at least one of the left and right passenger footrests. An output of the electronic stability system is defined at least in part on the signal from the passenger footrest position sensor.

Method for the producing of an extruded frame element with battery pack profile for use in a bicycle frame comprising a plurality of frame elements, where the frame elements are interconnected and constitute a structure with such great rigidity that the bicycle frame under ordinary loading does not change its geometrical shape, wherein the at least one frame element is extruded with variable material thicknesses in a given cross sectional profile, and a recess is made in the at least one extruded frame element, as well as a bicycle frame comprising such a frame element, wherein a stable bicycle frame with sufficient strength is achieved, and wherein the bicycle frame becomes as discreet as possible.

A bicycle inductive lock included a housing, a lock body, and a control circuit device. An annular latch and the lock body are disposed in the housing. A back cover is configured to close the housing. The annular latch has a first engaging groove, a second engaging groove and a third engaging groove. The lock body includes a first baffle that can be engaged in the first engaging groove or the second engaging groove, a second baffle that can be engaged in third engaging groove, and a speed reduction motor having a lever. The lever includes an angle control block and an eccentric paddle. The control circuit device includes an induction unit and a key fob. The key fob is configured to generate induction with the induction unit for transmitting a signal. With the above configuration, the bicycle inductive lock can sense the signal to be locked or unlocked.

An electric assist bicycle and a drive system therefor includes a controller that includes control modes in which different assist ratios are calculated as control modes of the electric motor, and that stores a mode change condition that determines a change of the control mode. The controller performs the mode change when a pedal is located between an angular position that follows by 45 degrees a lowermost position of a locus of the pedal and an angular position that precedes by 45 degrees the lowermost position. Accordingly, the mode change is performed when the pedaling force exerted by a rider is relatively low such that the rider does not feel uncomfortable due to a rapid change of the load applied to the rider.

A tri-mode collapsible scooter includes: a deck; a stem; handlebars; a head tube; a neck hinge; a deck hinge; a wheelset; a neck control; and a deck control. The deck includes: a front deck section; a rear deck section; and a deck hinge interposed between the front deck section and the rear deck section. The neck control is configured to release the neck hinge for transition between an open neck position and a closed neck position. The deck control is configured to release the deck hinge for transition of the deck between an open deck position and a closed deck position. The deck hinge occupies the open deck position and the neck hinge occupies the open neck position in a ride mode; and the deck hinge occupies the closed deck position and the neck hinge occupies the closed neck position in a tow mode.

To provide a circuit module, a bicycle electric component, and a communication system that are easily matched to a communication system that uses power line communication, a circuit module is configured to be mounted on a bicycle electric component. The circuit module includes a first circuit board, a communication converter configured to convert between information appropriate to power line communication and information appropriate to communication other than the power line communication and mounted on the first circuit board, and a plurality of first terminals formed on the first circuit board. The plurality of first terminals is connected to a second circuit board included in the electric component.

A bicycle seatpost system is basically provided with a height adjustable seatpost and an electronic controller. The height adjustable seatpost includes an electric actuator. The electronic controller is configured to control the electric actuator to change a height of the height adjustable seatpost in accordance with detected information about a change of orientation of a bicycle relative to a ground.
