A suspension control device is provided for a human-powered vehicle. The suspension control device includes a sensor and an electronic controller. The sensor is configured to detect information relating to a ground contact condition. The electronic controller is configured to selectively control a suspension of the human-powered vehicle in accordance with the information detected by the sensor.

A wear computing system (100, 200, 300) for computing a wear of a wheel (3) of a vehicle (2) comprises a revolution sensor (48) configured to detect a number of revolutions of the wheel (3), an acceleration sensor (49) configured to detect an acceleration of the vehicle (2) in a travel direction thereof, and a control unit (7) configured to compute a travel distance of the vehicle from the acceleration of the vehicle, and compute the wear from the travel distance and the number of revolutions of the wheel (3).

A human-powered vehicle control device is configured to automatically control a suspension and an adjustable seatpost to a suitable state. The human-powered vehicle control device includes an electronic controller configured to control at least one of the suspension and the adjustable seatpost mounted to the human-powered vehicle upon detection of an inclined state of the human-powered vehicle based on a change in pressure of at least one tire of the human-powered vehicle. The pressure of the at least one tire is detected by a pressure detector configured to detect pressure of the at least one tire of the human-powered vehicle.

A system for a motorized vehicle having a frame and a wheel rotatably coupled to the frame has a first fender housing mounted to the frame, a second fender housing coupled to the first fender housing so that a volume is defined therebetween and an electronic component disposed in the volume.

A motorcycle (10) comprising a first frame member (110) having a first opening (128) and a plurality of wires. A joint member (140) is coupled to the first frame member and at least a second frame member (122, 62). The joint member has a second opening (142) therethrough. The plurality of wires extend into the first opening through the first frame member and through the second opening of the joint member.

A battery wheel assembly is disclosed that includes a wheel having an axle for securement to a vehicle, the axle having a central axle axis extending therethrough, a wheel rim and interconnected wheel hub rotatable about the central axle axis. The battery wheel assembly further includes a battery pack that includes a carrier wreath secured to the wheel rim, and a plurality of battery cells electrically interconnected and secured to the carrier wreath.

A bicycle part includes a housing and a lid. The housing includes an inner peripheral portion, an outer peripheral portion, an end wall portion and a connecting portion. The outer peripheral portion is spaced radially outward from the inner peripheral portion with respect to a center axis of the enclosed area. The end wall portion interconnects the inner peripheral portion and the outer peripheral portion to at least partly define an internal space. The connecting portion interconnects the inner peripheral portion and the outer peripheral portion. The lid overlies the internal space. The lid is welded to the inner peripheral portion along an inner weld path and the outer peripheral portion along an outer weld path. The lid is further welded to at least part of the connecting portion of the housing a connecting weld path connecting the inner weld path and the outer weld path.

Piezoelectric devices mountable on a rigid mechanical structure are described. A piezoelectric device includes one or more piezoelectric elements and one or more supporting structures. A respective supporting structure of the one or more supporting structures has a flat or non-flat surface and is mechanically coupled with a piezoelectric element of the one or more piezoelectric elements so that a mechanical force on the one or more supporting structures is converted into an electrical signal by the one or more piezoelectric elements. A piezoelectric device system including two or more piezoelectric devices and a method for generating electrical signals are also described.

A device for measuring the pressure of a two wheeler tire comprises: a connector to connect the device to a valve of the two wheeler tire; a valve opener to open the valve, so that in the connected state with the valve, pressurized air flows out of the two wheeler tire through the valve into the device, until the pressure in the device corresponds to the pressure in the two wheeler tire; a pressure measuring device to measure the pressure in the device; and a transmitter to wirelessly transmit information about the measured pressure. A method for monitoring the pressure of a two wheeler tire includes: determining the actual pressure and desired pressure of the two wheeler tire; comparing the actual and desired pressures; and indicating the actual pressure and/or the desired pressure and/or the difference between the desired and actual pressures of the two wheeler tire.
