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 bicycle sprocket comprises sprocket teeth. The sprocket teeth include a first tooth and a second tooth. The first tooth has a chain-engaging axial width which is larger than a first distance defined between opposed inner link plates of a bicycle chain and which is smaller than a second distance defined between opposed outer link plates of the bicycle chain. The second tooth has a chain-engaging axial width which is larger than the first distance and which is smaller than the second distance. The first tooth and the second tooth are spaced apart from each other in a circumferential direction of the bicycle sprocket to define a space which is free of a tooth configured to engage with the bicycle chain.

Abstract: A sprocket is engageable with a chain having rollers. The sprocket includes a body and a tooth portion. The tooth portion has front and rear surfaces, a drive side surface and a non-drive side surface. The rear and front surfaces face in opposite axial directions. The drive side surface axially connects the front and rear surfaces on a downstream side. The non-drive side surface axially connects the front and rear surfaces on an upstream side. One of the front and rear surfaces has a first chamfered portion, which is formed in a radially outer portion of at least one tooth portion and tapered radially outward in the axial direction. The drive side surface has a first protrusion, which protrudes downstream in the drive rotation direction and is located radially outwardly from a contact position where the drive side surface contacts each of the rollers when the chain is driven.
