Abstract: A bicycle control device includes an electronic controller configured to control an operational state of an electric auxiliary drive to a manual drive driving force inputted to the bicycle. The electric auxiliary drive assists in travel of a bicycle based on an operational state of a suspension of the bicycle. The electronic controller controls the operational state so that the bicycle is assisted at an assist ratio of the electric auxiliary drive.

Abstract: A motorcycle frame comprising a main frame and pivotless rear wheel suspension system. The main frame comprises frame members with threaded ends. The rear wheel suspension system comprises an axle block for each side of the wheel axle, with each axle block being releasably connected to the main frame by two members called absorbers that attenuate shock loads. Each absorber has a threaded end for threading to the threaded ends of the frame members. The other end of the absorbers is adapted to form a bolted connection with the axle block.
Abstract: A driving unit for use in an electric assist bicycle includes a rotation detection device in addition to a torque detection device such that the detection resolution of the rotation detection device is increased. The driving unit includes a housing, a crankshaft, a torque detection device, a rotating member, and a rotation detection device. The rotating member includes a connecting shaft and an output shaft. The connecting shaft is located at one of the ends of the rotating member disposed along its axis, and is coupled with the crankshaft in the housing. The output shaft is located at the other one of the ends of the rotating member disposed along its axis. The rotation detection device includes a detected portion and a detector. The detected portion is provided on the rotating member, and located around the central axis of the crankshaft in the housing.
Abstract: A remote control system includes a mobile device and a receiver connected to a control target. The mobile device includes an input unit accepting user's input operation; an operation signal transmission unit wirelessly transmitting an operation signal corresponding to the input operation during the input operation; a frequency switching determination unit determining whether to switch the transmission frequency band from a first frequency band to a second frequency band based on at least any one of a manner of the input operation and a state of wireless communication; and a transmission frequency switching unit switching the transmission frequency band when the frequency switching determination unit determines to switch the transmission frequency band. The receiver includes an operation signal reception unit receiving the operation signal; and a control unit controlling the control target on the basis of the received operation signal.
