A cable routing system of a bicycle, including a stem having a receiving space and an engaging hole communicating with the receiving space, a frame, a fork, an expander, and at least one cable. A head tube of the frame has a top portion having an upper mounting hole and a bottom portion having a lower mounting hole. The fork sequentially passes through the lower mounting hole, the upper mounting hole, and the engaging hole to be connected to the stem. The expander is disposed in a steering tube of the fork and has at least one cable passage communicating with the receiving space and the engaging hole. The cable extends into the steering tube from outside by passing through the receiving space and the cable passage. An end of the cable is connected to a bicycle controller, and another end thereof is connected to a bicycle component.

A bearing seat suitable for receiving a bearing includes an annular body, a first outer-radial flange and a second outer-radial flange. The annular body includes a peripheral wall. The peripheral wall has a first end, a second end, an inner matching surface and an outer surface. A thickness difference of the peripheral wall from the first end to the second end is within 30%. A portion of the inner matching surface is suitable for contacting and matching with an outer matching surface of the bearing. The first outer-radial flange protrudes from the outer surface adjacent to the first end and extends to the first end. The second outer-radial flange protrudes from the outer surface adjacent to the second end and extends to the second end. The overall structure of the bearing seat is uniform, which can reduce warpage and deformation caused by uneven shrinkage during the injection process.

An autonomous electronic bicycle comprises a frame, a front wheel that can be powered by a first electronic motor, a rear wheel that can be powered by a second electronic motor, and handlebars that can steer the front wheel which can be controlled by a third electronic motor. The autonomous electronic bicycle can operate autonomously, traveling to a chosen destination. When operating autonomously the autonomous electronic bicycle can shift between a set of balance modes, including a mode used when moving and a mode used when stationary but balanced. To transition between modes, a transition sequence of control commands can be selected and used.

Steering group of a motor vehicle including a front frame provided with a steering tube that rotatably houses a steering shaft or pin, which rotates about a steering axis, the front frame being provided with an upright integral with the steering tube, the front frame having a steering bracket (36), integral in rotation with the steering shaft where, the steering group includes elastic return means which elastically influence the steering shaft to position itself symmetrically with respect to the front frame, the elastic return means being interposed between the upright and the steering bracket so as to be compressed when the steering shaft rotates with respect to the central symmetrical position, wherein the elastic return means have a regressive trend elastic response.

Bicycle comprising a head tube (3), a down tube and a steering tube. The head tube comprises a cable passage (14) connecting the interior of the head tube with the interior of the down tube. The steering tube (16) engages an upper bearing (18) and a lower bearing (19) within the head tube. The upper bearing is below the cable passage. Cables (12) enter the head tube (3) at a top end of the head tube and leave the head tube via the cable passage (14) to the down tube (4).

A steering linkage assembly that allows an offset between a steering axis and a headtube axis of a bicycle. In turn, rider cockpit dimensions are divorced from vehicle performance aspects such that vehicle performance aspects may be tailored regardless of rider size. The steering linkage assembly generally includes linkage members on an opposite side of a linkage chassis than handlebars of the bicycle to improve performance by increasing steering angle range allowed by the linkage. In addition, different linkage members and linkage chasses may be provided to accommodate different offsets between the steering axis and the headtube axis.
