The disclosure provides a chain guide assembly configured to be mounted on a linkage assembly of a bicycle derailleur. The chain guide assembly includes an inner plate, an outer plate, a first connecting bridge and a second connecting bridge. The outer plate is spaced apart from the inner plate. Two opposite sides of the first connecting bridge are respectively connected to the inner plate and the outer plate. Two opposite sides of the second connecting bridge are respectively connected to the inner plate and the outer plate. The inner plate, the outer plate, the first connecting bridge, and the second connecting bridge are made of a single piece. In addition, the disclosure also provides a bicycle derailleur having the chain guide assembly and a structural reinforcement sheet of the chain guide assembly.

A chain guide is disclosed herein. The chain guide includes a backplate and a chain guide. The backplate has an elongated opening therein. The chain guide includes a guide to orient a chain with respect to the sprocket. The chain guide also includes a retaining assembly to removably and adjustably frictionally couple the guide at a given location along the elongated opening in the backplate, such that when the guide is rotated axially about the retaining assembly, the guide is retained at the given location.

A bicycle derailleur comprises a base member adapted to be mounted to a bicycle, a movable member movably coupled to the base member, and a chain guide coupled to the movable member. The chain guide is coupled for rotation around a rotational axis (X), and a biasing element biases the chain guide in a selected rotational direction. A resistance applying unit applies a resistance to rotational movement of the chain guide in a direction opposite the selected rotational direction, and an adjusting unit adjusts an amount of resistance applied by the resistance applying unit.

An assembly for minimizing the disengagement of a chain from a chain ring is disclosed. The assembly includes a bracket and a chain guide assembly. The chain guide assembly includes an inboard leg, an outboard leg, and a lock. The lock may be configured to allow a rider to remove the outboard leg of the chain guide assembly without tools.

A bicycle rear wheel sprocket arrangement which is rotatable about a common sprocket rotation axis that defines an axial direction and orthogonal to which are radial directions, comprising a plurality of sprockets of different sizes and number of teeth arranged coaxially along the sprocket rotation axis, which are connected to one another such that the sprockets jointly rotate about the sprocket rotation axis together, wherein the sprocket arrangement comprises a first partial arrangement that includes a largest sprocket, and a second partial arrangement that includes a plurality of sprockets formed integrally with one another. One partial arrangement has a plurality of elastically deformable latching formations that are in latching engagement with a plurality of mating latching formations of the other partial arrangement to prevent the two partial arrangements from separating in the axial direction.

A bicycle comprises front and rear wheels, a frame supported on the front and rear wheels and including a frame mount, and a battery including a battery mount engaged with the frame mount. One of the battery mount and the frame mount includes a depression and the other of the battery mount and the frame mount includes a boss positioned in the depression. Preferably, depression comprises a slot, and the slot can include a resilient material to securely hold the boss. The boss can comprise an eccentric boss. Preferably, the battery mount is positioned adjacent one end of the battery, and an opposite end of the battery includes an opening. In this embodiment, the bicycle further comprises a mounting pin positioned through the opening and through a portion of the frame to secure the opposite end of the battery to the frame.

A chainring protection system includes a chainring having a torque input section and a torque output section. The torque output section is radially outer relative to the torque input section and has a plurality of teeth. The chainring protection system also includes a cover connected to the chainring, such that the cover at least partially covers a circumferential portion of the torque output section. The circumferential portion of the torque output section includes less than all teeth of the plurality of teeth.

A bicycle frame is disclosed. In certain examples, the bicycle frame includes a head tube coupled to a top tube and a down tube, a seat tube coupled to the top tube and the down tube, and an upper pivot point disposed in the seat tube configured to pivotally couple to a rear suspension system. In certain examples, the bicycle frame includes a plurality of lower pivot points disposed in the seat tube configured to pivotally couple to the rear suspension system, each of the plurality of lower pivot points causing, when coupled to the rear suspension system, the rear suspension system to define a different wheel path as a rear wheel of the rear suspension system travels from an extended position to a compressed position.

A bicycle comprises front and rear wheels, a frame supported on the front and rear wheels and including a frame mount, and a battery including a battery mount engaged with the frame mount. One of the battery mount and the frame mount includes a depression and the other of the battery mount and the frame mount includes a boss positioned in the depression. Preferably, depression comprises a slot, and the slot can include a resilient material to securely hold the boss. The boss can comprise an eccentric boss. Preferably, the battery mount is positioned adjacent one end of the battery, and an opposite end of the battery includes an opening. In this embodiment, the bicycle further comprises a mounting pin positioned through the opening and through a portion of the frame to secure the opposite end of the battery to the frame.
