Provided are a new antenna, a bicycle including the new antenna, a display apparatus including the new antenna, and an unmanned aircraft including the new antenna. An antenna includes a first conductor, a second conductor facing the first conductor in a first direction, a third conductor, a fourth conductor, and a feeding line electromagnetically connected to the third conductor. The third conductor is located between the first conductor and the second conductor, apart from the first conductor and the second conductor, and extends in the first direction. The fourth conductor is connected to the first conductor and the second conductor and extends in the first direction. The first conductor and the second conductor are capacitively connected via the third conductor. The antenna is disposed in a bicycle component of a bicycle such that the fourth conductor faces the bicycle component.

A main body frame (100) for an electric motorcycle comprises a front fork support member (101) with a front fork through hole for loading a pivot stem of a front fork (200), the front fork through hole has a pivotal axis arranged in a central plane (P) of the main body frame; the main body frame further comprises a right and a left frame part (102, 105) arranged on opposite sides of the central plane of the main body frame, each having an elongated shape and being formed of an upper part (102a, 102b) and a lower part (102c, 102d), respectively at different sides of an elongation direction changing portion (102e), a first buffer member (120) attached, at opposite sides thereof, to the right and the left frame part, and crossing the central plane. wherein starting from the respective elongation direction changing portions thereof. the upper parts of the left and the right frame part extend inwardly towards the central plane so as to embrace the front fork support member, and are attached to opposite sides of the front fork support member, and a largest width (a7) of the main body frame in a width direction (Z) perpendicular to the central plane is 10 cm or more and 30 cm or less.

The invention relates to a single-track land vehicle, which is designed, for example, as a bicycle (1), electric bike or electric scooter and has a vehicle frame (2) and a vehicle fork (5), which (5) has a fork steerer tube (4), which fork steerer tube (4) is mounted pivotably in a head tube (3) of the vehicle frame (2), wherein it is possible by means of a pivoting-angle brake or limiter (6) to at least decelerate the pivoting in of the vehicle fork (5) relative to the vehicle frame (2) and/or to define the maximum pivoting-in angle. For the single-track land vehicle according to the invention, it is characteristic that the pivoting-angle brake or limiter (6) has a tension element (7), which (7) is connected to the vehicle frame (2) via a holding element (8) held in the interior of the vehicle frame (2) or held on the vehicle frame, and that a holding counter-element (9) is provided on the tension element (7) at a distance from the holding element (8), which (9) rests or strikes against the vehicle fork (5) or against the fork steerer tube (4) when the pivoting-angle brake or limiter is activated (cf. FIG. 5).

A bicycle lock system for inhibiting a bicycle from being stolen includes a bicycle that has a frame and a rear wheel. A locking unit is movably coupled to the frame and the locking unit is positioned adjacent to the rear wheel. The locking unit is positionable in a locked position having the locking unit extending through the rear wheel. In this way the rear wheel is inhibited from rotating thereby inhibiting the bicycle from being stolen. The locking unit is positionable in an unlocked position having the locking unit being displaced from the rear wheel thereby facilitating the rear wheel to freely rotate.

A straddle-type vehicle including a vehicle body frame to which a steering unit that supports a front wheel in a steerable manner and a stay to which a storage box is configured to be attached are attached. The vehicle body frame is provided with a head tube. The steering unit includes a steering stem rotatably penetrating the head tube, and a pair of left and right front fork tubes coupled to the steering stem and extending toward an axle of the front wheel. The pair of left and right front fork tubes pivotally supports the axle of the front wheel. The stay is located on an outer side of the front fork tubes in the vehicle width direction, and intersects with at least one of the steering stem and the front fork tubes in a side view.

An electric bicycle includes a front wheel, a rear wheel, a driving unit that transmits a driving force to at least one of the front wheel and the rear wheel, a battery housing area that is able to house a battery that supplies power to the driving unit, a head pipe, and a down frame extending from the head pipe in a diagonally downward and rearward direction of a vehicle body. The down frame includes a first extension extending in the diagonally downward and rearward direction of the vehicle body and a second extension extending in the diagonally downward and rearward direction of the vehicle body and provided side by side with the first extension in a width direction of the vehicle body. The battery housing area is located at least partially between the first extension and the second extension.

An electric scooter includes: a scooter body; a front fork pivotally arranged on a front side of the scooter body; a front wheel mounted on the front fork; a rear wheel arranged on a rear side of the scooter body; a handlebar including a crossbar and a riser, the crossbar being arranged at an upper end of the riser, and a lower end of the riser being coupled to the front fork; and a left steering light and a right steering light mounted on at least one of the scooter body, the front fork or the handlebar.
