Motor-integrated bicycle hub

Problem: To minimize a length of a frame mount portion of a motor-integrated bicycle hub in a hub axle direction. Solution: A motor-integrated hub 10 includes a hub axle 15 and a motor case 17. The motor case 17 has a recessed portion 32a capable of receiving a front fork 103 and houses a motor. In the motor-integrated hub, the motor case has the recessed portion 32a capable of receiving a front frame of the bicycle. In this case, for example, the distal end portion of the front fork to which a wheel is mounted among the frame can be arranged at the recessed portion. Consequently, a space can be formed around the recessed portion and an electrical component or the like can be housed using the space.
