A pivoting mechanism includes a rotation assembly and a fixation assembly. The rotation assembly includes a first member and a second member which are rotatable with respect to each other. The fixation assembly includes a first fixation member, a first elastic member, and a first pushing member. The first fixation member is received in the rotation assembly. The first fixation member selectively blocks the first member and the second member. The first fixation member is disposed between the first elastic member and the first pushing member.

The present disclosure is directed to a bicycle parking structure comprising a plurality of bicycle hangers supported by a crossbar assembly. Each bicycle hanger is configured to support a bicycle in a substantially vertical position. The bicycle hangers are spaced apart from one another along the length of the crossbar assembly. Each of the bicycle hangers may be secured to the crossbar assembly so that the bicycle hanger is fixed at a desired position or unsecured from the crossbar assembly so that the position of the bicycle hanger along the length of the crossbar assembly may be adjusted. In this manner, the distance between adjacent bicycles need not be fixed and the bicycle parking structure can be adapted for a particular space. The bicycle parking structure is designed to provide for a space-efficient, high-volume parking of bicycles.

A load-leveling hanging apparatus and a system for suspended lifting of objects are disclosed. The load-leveling hanging apparatus includes a carriage suspended from a line; a hanging beam adapted for attachment of multiple objects at points along the beam; a mechanism for moving the hanging beam relative to the carriage to thereby achieve a level condition; and a level indicator. The mechanism is a rotatable screw. The system includes the load-leveling hanging apparatus and a lifting device. The lifting device includes a drum for winding and unwinding a line; a motor coupled to the drum to apply a torque thereto; a guide to direct the line onto the drum; and a controller. The lifting device raises and lowers the suspended hanging apparatus.

A bike balance trainer apparatus for training a rider to balance on a single wheel of a bicycle and including a mount for a service stand and an attachment to allow it to act as a bike stand or storage apparatus is provided. The apparatus may have a base support member and a tire retention member movably connected to the base support member about a first pivot.

For parking a bicycle, a bicycle parking device includes a lower braced frame, a rotating platform, at least one rotating column structure, and a lifting device. The lower braced frame that installs a rotating platform and supports an upper supporting frame through a bracing rod. The rotating platform is arranged on the lower braced frame and a fan-shaped notch is arranged on the rotating platform. The at least one rotating column structure that supports the lower braced frame, wherein at least one rotating column structure supports the lower braced frame. The lifting device arranged in the rotating column structure is detachably connected to a carrier frame used for carrying bicycles.
