A front derailleur comprises a base member, a chain guide, and a linkage structure. The base member includes a mounting hole. The mounting hole has a center axis. The linkage structure comprises a first link member and a second link member. The first link member is pivotally coupled to the base member about a first pivot axis. The second link member is pivotally coupled to the base member about a second pivot axis. The first link member is pivotally coupled to the chain guide about a third pivot axis. The second link member is pivotally coupled to the chain guide about a fourth pivot axis. At least three of the first pivot axis, the second pivot axis, the third pivot axis, and the fourth pivot axis are non-parallel to and non-perpendicular to the center axis of the mounting hole.

The disclosure provides a bicycle front derailleur including a fixing component, a chain guiding component, a linkage assembly, a battery assembly, two terminals, a circuit board assembly and a driving module. Two opposite ends of the linkage assembly are respectively and pivotally disposed on the fixing component and the chain guiding component. The battery assembly includes a battery holder and a battery. The battery holder is disposed on the fixing component, and the battery holder has a battery slot. One terminal is disposed in the battery slot, and the battery is removably inserted into the battery slot and is electrically connected to the terminal. The circuit board assembly is disposed on the fixing component and electrically connected to the other terminal. The terminals are electrically connected to each other. The driving module is disposed on the fixing component and electrically connected to the circuit board assembly.

Kits for converting a single-speed bicycle to a multi-speed bicycle are described. Such kits typically include a front chainring set having 2-5 differently-sized front chainrings, a front derailleur compatible with the front chainring set, a front derailleur shifting assembly compatible with the front derailleur, a chain tensioner, and a chain sized to accommodate the gearing provided by the plurality of front chainrings and the existing or new rear sprocket(s) to be fitted to the rear wheel of the bicycle undergoing the conversion.

The disclosure provides a bicycle front derailleur configured to be mounted on a bicycle frame. The bicycle front derailleur includes a fixed component, a chain guide, a linkage assembly, and an adjustment component. The fixed component is configured to be mounted on the bicycle frame. Two opposite ends of the linkage assembly are respectively and pivotably disposed on the fixed component and the chain guide. The adjustment component is pivotably disposed on the fixed component. The adjustment component is configured to press against the bicycle frame so as to adjust a position of the bicycle front derailleur with respect to the bicycle frame.

A clamp configured for connecting a bicycle component to a tubular element of the bicycle. The body of the bicycle component has a through opening extending between surfaces of the body and a seat on one surface that connects with the through opening. The clamp has an annular band that is connected to a slider in the through opening. An actuation lever connected to the slider moves the slider between a release position and a clamping position. When the slider is in the claiming position, the actuation lever is position in the seat on the body.

An electric front derailleur is basically provided with a base, a chain guide, a linkage and an electric motor unit. The base is configured to be mounted to a bicycle. The chain guide is configured to guide a chain. The linkage movably couples the chain guide to the base in a forward-rearward direction to move the chain guide between a retracted position and an extended position in a mounted state where the base is mounted to the bicycle. The electric motor unit is supported on the base and operatively coupled to the linkage to move the chain guide between the retracted position and the extended position. The electric motor unit is arranged at least partly closer to the bicycle than the chain guide.
