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 sprocket and chain assembly for bicycles is revealed. The sprocket and chain assembly for bicycles includes a bicycle sprocket and a bicycle chain. A contact part of the bicycle sprocket and a contact part of the bicycle chain in contact with each other are made of a multi-layer clad metal which is composed of a first metal and a second metal. The first metal has higher hardness and density than the second metal. A surface material for the contact parts of the bicycle sprocket and the bicycle chain is the first metal for providing sufficient wear resistance and ensuring service life of both the bicycle sprocket and the bicycle chain. Moreover, the lightweight design of the bicycle sprocket and the bicycle chain is achieved and sufficient structural strength is provided by the contact parts made of the multi-layer clad metal.

An individual chain wheel for a bicycle front crank arrangement for engaging in a drive chain includes a plurality of teeth formed on a circumference of the chain wheel and having a first and a second group of teeth. The teeth of the second group of teeth are arranged in an alternating manner between the teeth of the first group of teeth. Each tooth has a load flank via which force is transmitted between an adjacent roller of the drive chain and the respective tooth. Each tooth of the first group may also have at least one profile with an opening in the vicinity of the flank, in which a portion of an inner link plate of the drive chain, which portion protrudes beyond the roller, engages.
