Abstract: A bicycle transmission apparatus comprises a base member, a first transmission member, a second transmission member, a first coupling member, a first guide structure, a switching device, and a transmission controller. The switching device is configured to switch a position of the first transmission member relative to the base member in an axial direction between a first axial position and a second axial position. The transmission controller is configured to control the switching device and the first guide structure so as not to change a first engagement state of the first coupling member from one cogwheel to another adjacent cogwheel among first cogwheels when the first transmission member moves relative to the base member in association with a movement of the first guide structure relative to the base member to change a second engagement state of the first coupling member from one cogwheel to another adjacent cogwheel among second cogwheels.

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.

Abstract: A bicycle drive unit comprises a housing configured to be mounted to a first base member. The housing includes a first wall at least partly defining an internal space to at least partly accommodate a bicycle crank having a crank rotational axis. The first wall includes a first transmitting surface disposed to at least partly face upward in a bicycle upright state where the crank rotational axis horizontally extends and the housing is mounted on the first base member. The first transmitting surface is configured to face a first receiving surface of the first base member to transmit an upward force from the housing to the first base member. The first transmitting surface being at least partly disposed below the crank rotational axis in the bicycle upright state.
