An intelligent safety frame capable of easily replacing and protecting battery includes a front beam, a battery mounting box, a rear beam, a cushion mounting seat and a rear tail box mounting seat, wherein a rear tail box is mounted on the rear tail box mounting seat, the cushion mounting seat is rotatably mounted on the rear beam, a battery mounting cavity is defined in the battery mounting box, a threading box is provided on a side of the battery mounting box, a first wire-in cavity is provided in the threading box, a first threading slot is provided on a side of the battery mounting cavity, a wire outlet is provided on a side of the threading box, a second intelligent lock mounting slot is provided at the upper end of the rear beam, and a lock catch is provided on a side of the cushion mounting seat.

Disclosed is a recumbent bicycle configuration, structure and methods which allow effective hand power input using only components otherwise required to pedal and steer. Force and work based hand power methods are used. The effect is comparable to standing and pedaling a conventional bicycle. The configuration has front wheel drive and steering. The crankset is fork mounted on or near the steering axis. The fork has a double triangulated torque tube structure which is rigid from the hand grips to the crankshaft endpoints to torsional hand and foot forces in opposition. Pedal forces on steering are controlled by a hand over foot leverage ratio, and by use of trail, which is increasingly effective with speed. A fork mounted fairing can be used. For stability, the fairing aerodynamic center of presented area is ahead of the steering axis. Hand, foot and selective braking inputs are used for enhanced control.

A two-wheeler mount preclusion apparatus comprising: a saddle-post block coupling a saddle with a post; a point of articulation disposed on the block; and a tool of manipulation at the point of articulation of said block, when manipulated, allowing for at least a degree of rotation of the saddle, wherein the rotation of the saddle renders the two-wheeler into a mount-precluded state.

An electric folding mechanism and a motorbicycle thereof, the electric folding mechanism is connected between a first part and a second part capable of being folded together, which comprises a folding motor (61), a transmission shaft (62) with two ends driven by the folding motor (61), and two hinge assemblies (63) respectively disposed at each end of the transmission shaft (62); each hinge assembly (63) comprises a first hinge component (631) and a second hinge component (632) rotatably connected to the first hinge component (631); both the first hinge component (631) and the folding motor (61) are attached to the first part, and the second hinge component (632) with two ends is attached to the second part.

A mobile body (1A) includes: a base body (3) tiltably assembled to a movement operation section (2) that can move on a floor surface; an occupant riding section 6 installed to the base body (3) by a connection mechanism (4); an auxiliary ground contact section 7 connected to the occupant riding section (6) and in contact with the floor surface in a slidable or rollable manner when a tilt amount of the occupant riding section (6) with respect to the floor surface increases to a predetermined amount; and a control device (80) which controls the movement of the movement operation section (2) to stabilize the attitude of the mobile body (1A). The connection mechanism (4) elastically rocks the occupant riding section (6) with respect to the base body (3) according to the movement of the center of gravity of a user P riding on the occupant riding section (6).
