An electric bicycle includes a frame that has a concave or arc shape. The bicycle also includes two wheels—a front wheel and a rear wheel, with each wheel being connected with an end portion of the frame. A battery-powered electric motor may be connected with the rear wheel to drive the rear wheel and propel the bicycle forward. The battery may be rechargeable. The speed of the bicycle may be controlled by the operator moving a lever with one of their feet. A rotatable knob located on the frame may be used as a cruise control speed setting device. The electric bicycle may be steered by the operator using their feet resting on a pair of foot pegs that are attached to or connected with the front wheel. The electric bicycle may include a regenerative braking system or a friction braking system.

A driving support system (1) for motorcycles including: an external sensor unit (2) which recognizes a road state ahead of one's own vehicle; a collision risk determination unit (62) which determines a level of collision risk between one's own vehicle and an object ahead of one's own vehicle based on a recognition result of the external sensor unit 2; an automatic braking control unit (61) which executes automatic braking to automatically operate a brake device (83) in response to the determination result by the collision risk determination unit (62); and a departure risk determination unit (64) which determines a level of departure risk of one's own vehicle to outside of one's own vehicle travel lane in a case of executing the automatic braking. The automatic braking control unit (61) ends execution of the automatic braking in a case of being determined that the departure risk is high.

The invention comprises a truck and riding devices with a lean steering spatial mechanism comprised of rigid bodies and a single compliant body connected by joints forming a closed kinematic chain wherein the compliant body provides compression, tension, and torsional return spring forces for multi-axial functionality within the constraints of the lean steering spatial mechanism, allowing for the combined functionality of deep deck lean, improved lean steering control over a wider range of speed, improved speed stability, and full load bearing suspension. The invention has additional degrees of freedom and additional primary motions of floating and suspension.

In an electric steering lock device for saddle-ride type vehicle, a casing movably supports a lock pin and a slider. The lock pin is linearly movable between a lock position and an unlock position. The slider is movable in a direction identical to a movement direction of the lock pin. The casing houses an elastic member that is interposed between the lock pin and the slider, and an electric motor that provides a power that drives the slider. The electric steering lock device for saddle-ride type vehicle avoids being large-sized and reliably detects a position of the lock pin. A casing 18 movably supports a first interlocking member 72 and a second interlocking member 73. The first interlocking member 72 moves in a direction identical to a lock pin 19 by interlocking with the lock pin 19. The second interlocking member 73 moves in a direction orthogonal to the movement direction of the lock pin 19 and the first interlocking member 72 by interlocking with the first interlocking member 72. A switch 74 that detects a position of the second interlocking member 73 is mounted on the casing 18.

A left suspension unit supports a left wheel. A right suspension unit supports a right wheel. A steering actuator imparts a force causing the left suspension unit and the right suspension unit to turn about a left steering axis and a right steering axis respectively to a steering force transmission mechanism. A leaning actuator imparts a force causing a body frame to lean leftward or rightward of a leaning vehicle to a link mechanism. A control unit is capable of selecting a first mode wherein both of the steering actuator and the leaning actuator are employed, and a second mode wherein the steering actuator is employed without employing the leaning actuator, in order to control a leaning angle of the body frame in cooperation with a steering mechanism.
