A bicycle electric component setting system is basically provided a master unit and a plurality of slave bicycle electric components. The master unit is configured to be mounted to a bicycle. The master unit is configured to receive update information from an external terminal device. The slave bicycle electric components are configured to be mounted to the bicycle. The slave bicycle electric components are configured to receive the update information from the master unit to change a setting of at least one of the slave bicycle electric components.

A linear actuator system includes a linear actuator including an outer body, an inner body disposed within the outer body, a fluid chamber at least partially extending between the inner body and the outer body, a piston chamber extending at least partially within the inner body, a valve configured to selectively fluidly couple the fluid chamber and the piston chamber to each other, a piston assembly including a piston, a variable volume within the piston chamber that extends between the piston and the valve, and a gas collector assembly including a fluid passageway. The piston assembly is disposed within the piston chamber, wherein a movement of the piston assembly causes a gas separated from a liquid within the variable volume to flow through the fluid passageway, through the valve, and into the fluid chamber.

An operating system for a human-powered vehicle comprises a first operating device, a second operating device, a first user interface, and a second user interface. The first operating device comprises a first base member and a first operating member. The second operating device comprises a second base member and a second operating member. The first user interface is configured to receive a first user input and mounted to the first operating device. The second user interface is configured to receive a second user input and mounted to the second operating device. At least one of the first user interface and the second user interface is configured to be operated to control an assist driving unit configured to assist a human power.

A bicycle electrical front derailleur is provided that basically includes a wireless communication unit, a movable member and an electrical actuation unit. The wireless communication unit is configured to wirelessly receive a control signal. The electrical actuation unit is configured to move the movable member according to the control signal, the electrical actuation unit including an electrical actuator having an output shaft extending downwardly in a state where the bicycle electrical front derailleur is mounted to a bicycle.

There is described a bicycle seat post assembly in which the travel distance of the seat post can be adjusted. The seat post assembly includes an outer tube that is configured to telescopically receive an inner tube. The inner tube is axially slidable relative to the outer tube between a retracted position and an extended position, the extended position being determined by an extension assembly in which an inner contact member engages an outer contact member, thereby setting the upper limit of axial extension of the inner tube. The extension of the inner tube can be limited to an intermediate position that lies between the retracted and extended positions by an insertable shim that is positionable between the inner and outer contact members.

A bicycle has a front fork, within which the front wheel is mounted, attached to the head tube. Extending downwardly from each end of a lateral member are downwardly projecting forks, each comprising a primary portion, the respective primary portions extending downwardly and substantially parallel to each other. The longitudinal axes of both the main portion and a rider's lower leg are aligned. By aligning the wakes created by the forks and the lower leg a reduction in overall system drag is provided. Additionally or alternatively, the rear wheel may be provided between downwardly projecting stays, each comprising a primary portion, the respective primary portions extending downwardly and substantially parallel to each other. By aligning the downwardly projecting stays with the lower leg beneficial drag reduction is achieved.

A physiotherapeutic conveyance with a forwardly mounted wheel, a chassis relative to which said forwardly mounted wheel is mounted, a seat mounted relative to said chassis on a seating mount, a rear axle associated with a pair of outwardly disposed first and second rear wheels, and a steering assembly associated with said pair of outwardly disposed rear wheels, wherein said steering assembly comprises a steering mechanism operable to adjust the orientation of the rear wheels.

Bicycle component motion control begins when a motorized bicycle component is commanded to shift or actuate. The bicycle component motion control compares parameters of a component of the bicycle to be moved, to predetermined thresholds to provide safe shifting or actuation. The shift or actuation starts only when the battery voltage and the battery temperature are within predetermined acceptable ranges, respectively. Once the shift or actuation has started, the shift or actuation is aborted if the battery voltage remains below a predetermined low voltage threshold for a predetermined amount of time. If the shift or actuation is aborted when the component is in a position, in which the bicycle may not operate at a particular level or is inoperable, the shift or actuation command is modified to move the component to a previous position or an intermediate position.
