An inner link plate for a bicycle chain is provided. The inner link plate may have a longitudinal centerline defining a longitudinal direction and comprising a first inner-link end portion including a first inner-link opening having a first inner-link center axis, a second inner-link end portion including a second inner-link opening having a second inner-link center axis parallel to the first inner-link center axis, and an inner-link intermediate portion interconnecting the first inner-link end portion and the second inner-link end portion. The first inner-link end portion may have an extended edge portion extending to be away from the second inner-link end portion in the longitudinal direction.

An electric vehicle or toy having a drag reducing system to allow the electric vehicle or toy to facilitate manual or unpowered operation. The electric vehicle or toy can include a mode-switching system which can switch the electric vehicle or toy between an electric-operation mode to a manual-operation mode. The manual-operation may decouple one or more components of the electric drive system to reduce rolling resistance or drag. The electric vehicle or toy can include one or more one-way bearings which allow components to freely rotate in a desired direction. For example, the one-way bearings can allow the electric vehicle or toy to freely rotate in a forward direction while inhibiting or preventing rotation in a rearward direction.

A bicycle frame system comprises a connection module that rotatably connects a front frame section to a rear frame section. The connection module comprises a hinge section and a clamp section. The hinge section is below the clamp section when the bicycle frame system is in a ridable orientation. The connection module hinge section has a horizontal axis of rotation configured for rotating a front bicycle frame section approximately 180 degrees downwards and rearwards relative to a rear bicycle same frame section to convert the bicycle frame system from a ridable configuration to a folded configuration. The connection module clamp section comprises a front clamp block, a rear clamp block and a fastening device. The fastening device is configured to secure the front clamp block to the rear clamp block when the bicycle frame system is in a ridable configuration. The interface between the front clamp block and the rear clamp block comprises at least one v-shaped feature configured to prevent the front clamp block from moving laterally relative to the rear clamp block when the front clamp block is pressed against the rear clamp block.

A connecting device for a chainring of a bicycle is disclosed, including a connecting disc, a shaft, and a crank. The connecting disc is adapted to be engaged with a chainring, and has an axial bore, a bulging portion bulging from a central portion of the connecting disc, and a surrounding portion, which is flat, and surrounds an outer periphery of the bulging portion. The shaft passes through the axial bore to be fixedly engaged with the connecting disc. The shaft has a connecting end. The crank has a connecting end engaged with the connecting end of the shaft, and a bearing end adapted to bear an external force to make the crank rotate around the shaft. Whereby, the amount of materials used to make the connecting device is decreased. At the same time, the manufacturing cost, the size, and the weight of the connecting device are all reduced.

A bicycle front derailleur is basically provided with a base member, a chain guide and a chain restricting abutment. The base member is configured to be mounted on a bicycle frame. The chain guide is configured to be movably coupled to the base member between a retracted position and an extended position to move a bicycle chain. The chain restricting abutment is configured to restrict the bicycle chain from moving in a radially outward direction of a rotational center axis of a bicycle front sprocket when the base member is mounted on the bicycle frame and the chain guide moves from the extended position toward the retracted position.

A bicycle-chain outer link plate comprises a first outer-link end portion, a second outer-link end portion, and a first outer-link intermediate portion. The first outer-link end portion comprises a first outer surface, a first inner surface, a first outer-link opening, and a first outer-link outermost edge. The first outer-link intermediate portion comprises a first intermediate outer surface, a first intermediate inner surface, a first outer-link intermediate outermost edge, a first additional outer-link intermediate outermost edge, and a first intermediate chamfer. The first intermediate chamfer has a first minimum distance defined between the first outer-link intermediate outermost edge and the first inner edge along a reference line. A distance defined between the first outer-link intermediate outermost edge and the first additional outer-link intermediate outermost edge on the reference line is minimum in the first outer-link intermediate portion. The first minimum distance is equal to or larger than 1 mm.
