Abstract: A bicycle includes a frame having a first segment and a second segment each elongated along a longitudinal axis. A hinge includes a first face on the first segment and a second face on the second segment. The first face and the second face are rotatable relative to each other about a rotational axis. The rotational axis extends at a non-right angle relative to the longitudinal axis.

Abstract: A garment for cycling, having indicating lights associated with sleeves of the garment; first and second accelerometers provided on respective sleeves; and a controller configured to receive data from the accelerometers and determine from the date whether a wearer of the garment has raised an arm to indicate a maneuver. The controller is further configured to illuminate the appropriate indicating light depending on which arm has been raised, and to compare the data from the first and second accelerometers to filter out movements common to both the first and second accelerometers and determine when the sleeves are being moved independently of one another in a manner to indicate a turn.

Abstract: An electric bike is described and includes an air speed sensor to sense air speed at the bike, an electric motor to impart motive force to the bike, and a controller operatively connected to the motor, the controller to control the electric motor using the air speed sensed by the air speed sensor. The controller includes a set electric-motor parameter for the output power of the motor. The electric-motor parameter can be bike speed. The controller can also use ground inclination to determine the power to be output by the motor to assist in powering the bike. The controller can use ground inclination to determine the power to be output by the motor to charge a battery in the bike. The controller can set the power of motor assist to be greater in a greater headwind than in a lighter headwind. The controller uses rider weight and rider height as parameters for controlling the motor.

The apparatus includes a first gear component coupled to a second bicycle frame component, and the gear component is rotatably coupled within the first pair of brackets. The first gear component has a first set of recesses radially spaced from each other about a periphery thereof. The apparatus further includes a first clamping component engaging at least one of the first pair of brackets and selectively biasing the first protrusion into one of the first set of recesses to rotatably lock the first gear component with respect to the first pair of brackets.

Abstract: An apparatus includes a first component having with a first coupling surface and a first axial aperture therethrough. The first component has an axial recess in the first coupling surface. The apparatus further includes a second component having a second coupling surface and a second axial aperture therethrough, and the second component has an axial protrusion extending from the second coupling surface. The axial recess of the first component and the axial protrusion of the second component selectively engage to radially lock the first component relative to the second component and align the first and second apertures upon engagement with each other. The first and second apertures selectively receive a bicycle wheel axle.

Abstract: An apparatus includes a substantially cylindrical and hollow main body having an open end and a closed end and a bayonet component extending therein. The bayonet component has a shaft at least partially enclosed within the main body and a pair of opposing protrusions extending radially outside of the main body proximate to a first end of the shaft.
