摘要： A bicycle controller controls a motor in accordance with the riding environment of a bicycle. The bicycle controller includes an electronic control unit that is configured to control a motor that assists in propulsion of a bicycle in accordance with a manual driving force. The electronic control unit is further configured to sets a response speed of the motor with respect to a change in the manual driving force for a case in which a vehicle speed of the bicycle is less than or equal to a first speed to be different from the response speed for a case in which the vehicle speed of the bicycle exceeds the first speed.

摘要： A drive unit for an electrically assisted bicycle includes a housing, a motor in the housing, a crank shaft extending through the housing along a right-left direction of the bicycle, and a pair of bearings rotatably supporting the crank shaft within the housing, wherein each bearing includes an inner ring and an outer ring. The pair of bearings include a first bearing at one side of a thrust direction and a second bearing at another side along the thrust direction, wherein the thrust direction is an axial direction of the crank shaft. The first bearing does not move along the thrust direction relative to the crank shaft. The drive unit has a movement restricting structure that restricts movement of the first bearing relative to the relative to the housing along the thrust direction.

摘要： An ebike comprises a front wheel, a rear wheel, a frame structure supported on the front wheel and the rear wheel, a crank assembly, and a battery assembly. The frame structure includes a down tube defining a down tube axis and being open at its lower end. The crank assembly is rotatable about a crank axis that is spaced rearward from the down tube axis. The battery assembly is slidable into the down tube from the lower end of the down tube along the down tube axis. The battery assembly includes a battery housing protruding from the lower end of the down tube, and a battery cover secured to a lower end of the battery housing and substantially enclosing the lower end of the battery housing. At least a portion of the battery housing may extend below a horizontal plane defined by the crank axis.
