A battery storage device includes a battery case (42) storing a battery (62A or 62B) and a case side connection terminal (43) connected to a terminal portion (41) of the battery (62A or 62B) stored in the battery case (42). The battery storage device further includes a terminal displacement mechanism (45) and an operation member (44). The terminal displacement mechanism (45) causes the case side connection terminal (43) to be displaced between a connection position (P1) contact-connected to the terminal portion (41) of the battery (62A or 62B) and a retreat position (P2) separated from the connection position (P1). The operation member (44) is capable of operating the terminal displacement mechanism (45).

A bracket element configured for installation on an axial inner side of an associated bracket portion of a bicycle frame for the purposes of installing a rear gearshift mechanism of a derailleur system on the bicycle frame is provided. The bracket element may include a first portion, which has an opening or aperture assigned to the axle and which, in the installed state, is subjected to a clamping force which acts between the rear bracket portion. The bracket element may also include a second portion having an installation opening which is radially offset in relation to the opening or aperture in the installed state with respect to the axis and to which an attachment end of a base element of the rear gearshift mechanism is fixable.

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 training aid device comprising a cantilevered handle member for grasping by a user and guiding and/or supporting a bicycle, the cantilevered handle member disposed laterally adjacent to and extending in a direction outwardly away from a rear wheel of the bike and is retained on the frame of the bicycle using a plurality of attachment plates, wherein the plurality of attachment plates are configured to be coupled together with fasteners and each having a plurality clips configured to receive frame members on the frame of the bicycle.

A latching mechanism removably attaches an accessory to an offroad vehicle without requiring tools. The latching mechanism includes a body, a shaft extending through the body, and a handle riding on a conical surface of the body for rotating the shaft relative to the body. An oblong head extends on a lower side of the body, rotatable by the handle and shaft to a position where the head extends under a shoulder of a mounting recess. A spring system biases the head axially, such that the head can be moved either upwardly or downwardly from a balanced elevation set by a nut tightenable on a bolt. The mounting recess has an upper portion shaped differently from a lower portion. The body includes a hooking portion which extends significantly above the top of the mounting recess.

The present disclosure relates to a bicycle quick release device. The bicycle quick release device includes: an inner shaft; a lever connected to one end of the inner shaft, the lever being reciprocatively swingable between a release position and an urge position; an outer sleeve provided for the inner shaft to pass through, an outer circumferential face of the outer sleeve being provided with a sleeve body, an abutting portion disposed on one end of the sleeve body and an expansion portion disposed on the other end of the sleeve body, the expansion portion being provided with a plurality of axially extending sectioned grooves; an urging unit disposed between the lever and the abutting portion of the outer sleeve; and a tapered expansion unit connected to the other end of the inner shaft, an outer circumferential face of the tapered expansion unit being provided with a conical face.

A luggage rack for securing an item of luggage to a motorcycle or a scooter includes an adapter plate on which the item of luggage may be fastened. The adapter plate includes at least one positioning element configured to position the adapter plate relative to the motorcycle or motor scooter, and a displacement device having a lever and an engagement element which cooperate to secure or release the adapter plate from the motorcycle or motor scooter when the lever is moved between an open position and a closed position to cause the engagement element to slide into and out of engagement with a fixing point on the motorcycle or motor scooter.

A sprocket support body comprises at least ten external spline teeth including a plurality of external-spline driving surfaces. The plurality of external-spline driving surfaces each includes a radially outermost edge, a radially innermost edge, and a radial length. A total of the radial lengths of the plurality of external-spline driving surfaces is equal to or larger than 7 mm. At least one external-spline driving surface has a first external-spline-surface angle. The first external-spline-surface angle ranges from 0 degree to 10 degrees. One tooth of the at least ten external spline teeth having a first circumferential spline size. The other teeth of the at least ten external spline teeth each have a second circumferential spline size that is smaller than the first circumferential spline size. A total number of the other teeth of the at least ten external spline teeth being equal to or larger than nine.

A three-dimensional folding frame is disclosed including a first pivot portion for providing a front folding wheel frame with movable folding; a second pivot portion for providing a rear folding wheel frame with movable folding; a third pivot portion for providing a handlebar vertical rod with rotatable folding; and a fourth pivot portion for providing a crossbar with rotatable folding. The crossbar includes a first folding arm and a second folding arm; the first folding arm is movably connected to the front folding wheel frame by means of the first pivot portion; the front folding wheel frame rotates about the first pivot portion and can move relative to the first folding arm; the second folding arm is movably connected to the rear folding wheel frame by means of the second pivot portion.
