    Abstract: An apparatus for determining bicycle pedaling may include a sensor that detects the angular velocity and position of a drivetrain or rear sprocket assembly of the bicycle and a processor that is configured to compare the detected values against values indicative of at least one pedaling state. The apparatus may be configured to be housed within a component of the bicycle, such as within a hollow opening of the spindle or crank axle. The apparatus also may include a wireless transmitter to communicate with another component, such as a suspension controller.

    Abstract: A bicycle rear derailleur includes a base member mountable to a bicycle frame. A movable member is movably coupled to the base member. A chain guide assembly is rotatably connected to the movable member for rotation about a rotation axis. A biasing element is configured to bias the chain guide assembly for rotation in a first rotational direction with respect to the movable member. A damper assembly is operatively disposed between the chain guide assembly and the movable member to apply a damping force to the chain guide assembly when the chain guide assembly rotates in a second rotational direction opposite to the first rotational direction. The damper assembly includes a one-way roller clutch assembly disposed coaxially about the rotational axis and a friction unit extending circumferentially over a circumferential angle coaxially about the rotational axis.

    Abstract: An electromechanical rear derailleur is provided for a bicycle, including a base member for attachment to the bicycle along a mounting axis. A movable member has a cage assembly attached thereto. A linkage is provided including pivot axes oriented substantially perpendicular to the mounting axis, the linkage coupling the movable member to the base member and operative to enable movement of the movable member relative to the base member in a direction substantially parallel to the mounting axis. A power source powers an electric motor connected thereto and a transmission is coupled to and actuated by the motor to move the movable member.

    Abstract: A bicycle with an electric pedal assist motor capable of driving a chainring independent of cranks includes wheel speed sensors and crank cadence sensors. The wheel speed sensors and the crank cadence sensors measure wheel speed and crank cadence, respectively, and provide the measured wheel speed and crank cadence to controller of the bicycle. The controller activates motor overdrive based on the measured wheel speed and/or the measured crank cadence.

    Abstract: A bicycle front shifting system includes operable to transmit a wireless signal, a crank assembly with two crank arms and a pedal on each of the two crank arms. The crank assembly is rotatable about a rotation axis. A front shift unit is coupled to the crank assembly and is rotatable about the rotation axis. The front shift unit includes a chain ring component with a big chain ring and a small chain ring. The small chain ring has a small diameter and the big chain ring has a big diameter that is larger than the small diameter. A shift mechanism is coupled to and rotatable with the chain ring component about the rotation axis. The shift mechanism is configured to receive the wireless signal from the shifter and to shift a chain between the big chain ring and the small chain ring according to the wireless signal.

    Abstract: A control device for a hydraulic brake for a bicycle includes a reservoir for hydraulic fluid. The reservoir has a variable volume. The control device also includes a reservoir cover at least partially defining the reservoir, and a support that is attachable to a handlebar of the bicycle via an inner annular surface of the support. A handlebar proximity zone is radially outer relative to the inner annular surface of the support and is within two centimeters of the inner annular surface of the support. At least part of the reservoir cover is within the handlebar proximity zone.
