An adjustable bottom bracket mechanism, comprising: a bottom bracket, an axial connection portion and a mounting portion. The bottom bracket includes at least one shaft through hole and is configured for connection of a seat tube. A lengthwise extension direction of the seat tube is defined as a first direction. The axial connection portion includes at least one axial through hole and axially corresponds to the at least one shaft through hole. The mounting portion is connected to the axial connection portion and adjustably fixedly connected to the bottom bracket in a first position or a second position. When the mounting portion is in either of the first and the second position, axes of the at least one shaft through hole and the at least one axial through hole are located on the first direction.

A saddle-ride type vehicle in which a rear frame and a rear suspension can be attached to a vehicle body frame with a small number of parts and with a simple structure. The saddle-ride type vehicle includes a rear frame fastened to a frame portion of a rear portion of a vehicle body frame, and a rear suspension disposed at a rear portion of the vehicle body frame. The vehicle body frame includes a tubular member inserted into the frame portion in a vehicle width direction and fixed to the frame portion. The rear frame is fastened by a frame fastener to a frame fixation portion provided at an inner end portion of the tubular member in the vehicle width direction, and the rear suspension is connected to a suspension connecting portion provided at an outer end portion of the tubular member in the vehicle width direction.

The present disclosure provides a multifunctional children's ride-on vehicle including a frame, a vehicle head, a front wheel, pedal mechanisms, a rear frame, a seat, rear wheel brackets, rear wheels, and a push rod. The frame is provided with a plurality of adjusting grooves, and the plurality of adjusting grooves are evenly distributed along the frame. The rear frame is provided with an adjusting block corresponding to the adjusting groove, and the adjusting block is embedded into the adjusting grooves. The frame is provided with a frame accommodating groove at the front end thereof, and the frame accommodating groove has a size same as that of the adjusting groove.

An electronic device is configured to suitably control of a human-powered vehicle component. The electronic device includes a communicator configured to wirelessly communicate with a pressure detector detecting pressure of at least one tire of the human-powered vehicle. The electronic device is provided in a human-powered vehicle component including at least one of a transmission mounted to the human-powered vehicle, a suspension mounted to the human-powered vehicle, and an adjustable seatpost mounted to the human-powered vehicle.

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.
