Disclosed is a bicycle bag suitable to be straddled over a structural tube of a bicycle in a folded position and convertible to a backpack in an open position. The structural tube may include the top-tube or the bottom-tube of the bicycle. There is provided, in accordance with an embodiment of the present invention, a bicycle bag suitable to be straddled over a structural tube of a bicycle in a folded position and convertible to a backpack in an open position.

A bicycle container including a main body for containing objects and an engagement member provided on the main body. The engagement member is configured to engage with a pedal of a bicycle to enable the bicycle container to be detachably coupled to the pedal to hold the bicycle in an uptight position.

An apparatus for securing articles to structural members includes a main strap assembly having at least three distinct portions configured for forming a secure loop by attachment of at least one of the portions to another of the portions. The apparatus further includes a pair of parallel ancillary strap assemblies attached transversely to the main strap assembly. Each of the pair is attached to a respective one of ancillary releasable engagement mechanisms at an end thereof, for forming an engageable loop. The ancillary strap assemblies can be used to attach the main strap assembly parallel to an elongate structural member. The secure loop of the main strap assembly can be used for securing a heavy article to a bicycle frame, or the like.

Provided is a thin collapsible two-wheeled vehicle including: a pair of left and right mounting members provided to the main body frame to mount the rear wheel; wherein the pair of mounting members are each provided with a through hole penetrating each of the pair of mounting members respectively in left and right directions of the mounting members; the main body frame has a storage room therein, the storage room capable of storing the front wheel, the rear wheel, the saddle, and the handle; the rear wheel has an axle capable of moving within the through hole between a first mounting position and second mounting position; the rear wheel protrudes from the main body frame when the axle is mounted at the first mounting position, and the rear wheel is stored in the main body frame when the axle is mounted at the second mounting position.

A selectorized dumbbell includes a horizontal stack of nested left weight plates and a horizontal stack of spaced right weight plates with the stacks being separated by a gap into which a handle may be inserted. A selector is movable into different positions relative to the handle to vary how many nested left and right weight plates from the stacks thereof are coupled to the handle to vary the exercise mass of the handle. Each left weight plate has a counterpart right weight plate counterpart which are coupled together by at least one interconnecting member having a first keyhole slot connection between the left end of the interconnecting member and the left weight plate and a second keyhole slot connection between the right end of the interconnecting member and the right weight plate.

Provided is a closure device for connecting two assemblies to one another. The closure device includes a first closure part which has a locking piece with a first locking section and a first magnetic element, a second closure part which has a second locking section and a second magnetic element, and an arresting mechanism which is arranged on the second closure part and which has an arresting element and an actuating mechanism operatively connected to the arresting element. The arresting element can be brought into operative connection with the locking piece in the closed position, in order to lock the positively locked engagement between the first locking section and the second locking section. The actuating mechanism may be actuated in order to adjust the arresting element relative to the locking receptacle so that the first locking section and the second locking section are releasable from one another.
