A bicycle includes a vehicle-body frame, a front wheel that is a steered wheel, a rear wheel, a crankshaft, a pedal, a transmission to transmit rotation of the pedal to the rear wheel, a motor to apply at least a torque to cause rearward rotation of at least one of the front wheel or the rear wheel, a roll detector to detect at least one of a roll angle or a roll angular velocity of the vehicle-body frame, and a steering detector to detect a direction of steering. When a vehicle speed is zero and a steering angle of the front wheel is not zero, the motor applies, to the at least one of the front wheel or the rear wheel, a torque to maintain the roll angle of the vehicle-body frame based on the detected direction of steering and the at least one of the roll angle or the roll angular velocity.

A rear fork of a bicycle frame. The rear fork includes a base, a first arm, and a second arm. Each of the first arm and the second arm extend rearward from the base. At least one wheelie step is coupled to the rear fork. The wheelie step includes an extension rotatably coupled to and extending from one of the first arm and the second arm, and a foot step coupled to the extension. The extension is configured to rotate along an axis extending in a direction from the first arm to the second arm. A lock is configured to lock the extension to the one of the first arm and the second arm at different rotational positions along the axis.

A leaning-vehicle-traveling-state-data-output device includes a physical-quantity-data acquirer configured to acquire physical quantity data concerning a behavior of a leaning vehicle, a vehicle-traveling-state-data generator configured to generate vehicle-traveling-state data based on the physical quantity data and a vehicle-traveling-state-data-output controller configured to output the vehicle-traveling-state data. The vehicle-traveling-state-data generator generates vehicle-traveling-state data of the leaning vehicle in each of sections based on physical quantity data, the sections being obtained by dividing, into a plurality of sections, a single corner on which the leaning vehicle turns while leaning to perform a yaw motion continuously in an identical direction, the physical quantity data being acquired by the physical-quantity-data acquirer and concerning a behavior of the leaning vehicle while the leaning vehicle turns left on the corner while leaning leftward or turns right on the corner while leaning rightward.

A leaning-vehicle-real-time-information-presentation-control apparatus includes: a vehicle state detector; a turning motion determiner configured to determine whether a leaning vehicle is turning or not based on a detection result of the vehicle state detector; an individual-driving-skill-criterion setter configured to create an individual-driving-skill criterion during turning of the leaning vehicle; an individual-driving-skill-evaluation-result creator configured to evaluate evaluation-individual-traveling data based on an individual-driving-skill criterion during the turning of the leaning vehicle and to create an individual-driving-skill-evaluation result during traveling of the leaning vehicle; and an output controller configured to output the individual-driving-skill-evaluation result to at least one of an auditory device, a tactile device, or a vision device during the traveling of the leaning vehicle.

An auxiliary power for man-powered vehicles includes an air propelling device and a control system. The air propelling device is mounted on a man-powered vehicle for discharging air toward the back of the man-powered vehicle. Due to the reaction force, the man-powered vehicle is provided with forward thrust. The control system connects to the air propelling device in a wired or wireless manner to control the amount of air discharged by the air propelling device.

Electronic bicycles may communicate with each other to provide a communal biking experience to their riders. The electronic bicycles may collect rider data about their riders and may adjust the output parameters of the electronic bicycles based on the rider data. For example, the electronic bicycles may identify a weaker rider of the riders and may adjust the output parameters of the weaker rider's electronic bicycle to minimize a difference in the operation of the weaker rider's electronic bicycle and the stronger rider's electronic bicycle. Additionally, a parent rider may establish rider restrictions on an electronic bicycle ridden by a child.
