A mobile power pack fixed in a steering pipe of a bicycle includes a housing, a quick lock device, a fixing assembly, a mobile power source and a cover. The quick lock device is mounted on the connecting portion of the housing. The fixing assembly has a first fixing member inserted through the second receiving chamber and exposed out of the connecting portion to lock with the quick lock device, and first fixing member is screwed in the second fixing member. The quick release blocks of the quick lock device are pushed outward by the first fixing member to press against an inner surface of the steering pipe, so that the mobile power pack can be fixed in or released from a first receiving chamber of the steering pipe by the housing.

An air-cleaner structure of a saddle-ride vehicle is provided with an air-cleaner case arranged between a seat and a head pipe located in front of the seat. The air-cleaner case is provided with a bottom half and a top half. The bottom half is arranged in a space surrounded by a rear face of the head pipe and a pair of left and right main frames extending from the head pipe toward the rear of the vehicle. The top half is situated above the main frames. The top half is provided in a vertical two division structure. A dividing surface of the vertical two division structure of the top half is inclined in the vehicle-longitudinal direction. An air-cleaner element is mounted along the inclined dividing surface.

A motorized vehicle including: a front fork; a steering shaft able to rotate inside a steering column; at least one fork crown coupled to the steering shaft and to the front fork; and at least one electronic component intended to collect and/or transmit data relating to the operation of the motorised vehicle. The fork crown has a body in which there is formed a cavity closed by a cover and an electronic board housed in the cavity and able to centralize and/or process the data supplied by the at least one electronic component.

A bicycle battery pack that can be reduced in volume includes a housing configured to be located on a frame of a bicycle and battery cells accommodated in the housing. The battery cells include at least a first battery cell and a second battery cell. The housing includes a side wall extending in a longitudinal direction of the frame in a state located on the frame. An outer portion of the side wall includes at least one groove. The at least one groove is recessed toward a region between the first battery cell and the second battery cell.

A personal vehicle monitoring system is disclosed including a video camera coupled with a personal vehicle to show a view not in a direct field of view of a rider of the personal vehicle, and a display unit coupled with the personal vehicle and in communication with the video camera to display images captured by the video camera, wherein the display unit includes circuits and software to indicate various events such as other vehicles approaching the personal vehicle. The display unit includes a display device coupled with a display controller. The video camera communicates with the display controller via a video camera controller.

An angular speed acquisition device acquires the angular speed about a road surface perpendicular axis of a leaning vehicle. The leaning vehicle includes a vehicle body frame capable of leaning in a vehicle left-right direction and a steering shaft which steers at least one of a front wheel unit and a rear wheel unit. An angular speed acquisition device, which is mountable on the leaning vehicle, includes a memory and a processor. The memory stores the relationship between the steering angle, which is a rotation angle about the rotational axis of the steering shaft, the vehicle speed of the leaning vehicle, and the angular speed ω about the road surface perpendicular axis.
