Abstract: A bicycle component includes a drive unit and a battery. The drive unit includes a housing mounted on a bicycle frame, a crankshaft provided to a first portion of the housing, and a propulsion assist motor provided to a second portion of the housing. The battery is electrical connected to the propulsion assist motor to supply electrical power to the propulsion assist motor. The propulsion assist motor includes a rotational axis extending in a direction intersecting a direction in which the crankshaft extends. At least part of the second portion and at least part of the battery are accommodated in the frame in a state in which the second portion and the battery are arranged next to each other in a direction parallel to the rotational axis of the propulsion assist motor and the battery is coupled to the second portion in an attachable and detachable manner.

Abstract: A method for mounting a bicycle drive unit to a frame of a bicycle, in which the bicycle drive unit includes a housing, a crankshaft and a propulsion assist motor. The housing has a first portion and a second portion. The crankshaft is provided to the first portion. The propulsion assist motor is provided to the second portion and includes a rotational axis extending in a direction intersecting a direction in which the crankshaft extends. The method includes a first step of arranging the first portion at a position for mounting the first portion on the frame, and a second step of rotating the housing about an axis parallel to a rotational axis of the crankshaft and inserting the second portion into an opening of the frame after the first step.
