The crank C includes a crankshaft C1 rotatably supported by the frame A1, and a pair of crank arms C2 respectively provided at both ends of the crankshaft C1. The pedal PD is rotatably attached to the front end of each of the crank arms C2. Drive B can be selected from any type, belt drive type, or shaft drive type.

The front sprocket D1 is disposed on the crank C and is rotatable integrally with the crankshaft C1. The rear sprocket D2 is disposed at the hub HR of the rear wheel WR. The chain D3 is wound around the front sprocket D1 and the rear sprocket D2. The driving force applied to the pedal PD by the user riding on the human-powered vehicle A is transmitted to the rear wheel WR via the front sprocket D1, the chain D3, and the rear sprocket assembly D2.

The human powered vehicle A further includes a power assist unit E. The electric auxiliary unit E is actuated to assist the human power to drive the propulsion of the vehicle A. The electric assist unit E operates, for example, in response to a driving force applied to the pedal PD. The electric auxiliary unit E includes an electric motor E1. The electric assist unit E is driven by electric power supplied from the battery unit 60 mounted on the human-powered vehicle A. The human drive vehicle A can also omit the electric assist unit E.

The human powered vehicle A further includes a battery pack 1. The battery pack 1 is disposed on the frame A1 of the human powered vehicle A. In the present embodiment, the battery pack 1 is provided in the lower tube DT of the frame A1. The battery unit 1 is used, for example, in a state in which it is at least partially housed in the accommodating space DT1 (refer to FIG. 2) of the down tube DT. The lower tube DT is provided with an opening DT2 that opens downward in a state where the human-powered vehicle A is placed on the flat ground (refer to FIG. 2). The size of the opening DT2 is such that the battery pack 1 can be inserted into the accommodating space DT1. The battery pack 1 may be provided in a frame A1, a front fork A2, or the like different from the lower tube DT.

The structure of the battery pack 1 will be described with reference to Fig. 2 .

The pair of second engaging portions 22 are provided, for example, on the side of the connector 16 on the first supporting surface 14A of the movable member 14, and the connector 16 is disposed therebetween. In one example, the surface on the side of the opening DT2 (hereinafter referred to as "end surface 22A") of the second engaging portion 22 extends along the first direction DX (refer to FIG. 4). In a preferred example, the end surface 22A of the second engaging portion 22 has an arc shape that is recessed with respect to the opening DT2 as viewed in the second direction DY orthogonal to the first direction DX. In a more preferable example, the center of the arc of the end surface 22A of the second engaging portion 22 substantially coincides with the center of rotation AR of the turning point of the first engaging portion 20 (refer to FIG. 4). In this configuration, the battery unit 60 is guided to be smoothly attached and detached with respect to the battery holder 10, and the battery unit 60 can be easily attached and detached with respect to the battery holder 10. The second engagement portion 22 is formed such that the amount of protrusion from the first support surface 14A becomes smaller as it approaches the end portion farther from the first engagement portion 20 from the end portion closer to the first engagement portion 20 .
