Abstract
A bicycle transmission apparatus comprises a base member, an input shaft, a first transmission member, a second transmission member, and a first coupling member. The base member is configured to be attached to a bicycle frame as a separate member from the bicycle frame. The first transmission member is rotatable relative to the base member about a first rotational axis different from the input rotational axis. The second transmission member is rotatable relative to the base member about a second rotational axis different from each of the input rotational axis and the first rotational axis. The first coupling member is configured to couple the first transmission member to the second transmission member to transmit rotation of the first transmission member to the second transmission member at a variable speed stage.
