In accordance with example embodiments of the present disclosure, the invention provides a sports apparatus having an upper surface and a lower surface, the upper surface designed to slide on slippery surfaces such as snow, ice or sand and the lower surface having wheels and thus designed to glide along smooth hard surfaces.

Known vehicles, e.g. used for the sport of golf, which are configured combined for riding along and to be pushed with motorized support, exclusively comprise a steerable, rigid frame, causing the vehicle when positioned on the side of a slope to tilt parallel to the slope plane, consequently resulting in a disadvantageous, safety-relevant tilting moment. For improved driving safety, it should be possible to tilt the vehicle sideways. The vehicle according to the invention can be used in at least two operating modes. In the ride-along mode, at least a second and/or third vehicle component can be moved by the operator or an automatic, thus causing the vehicle to tilt sideways. This enables a carving effect and the tilt compensation as well as a straight-ahead drive at least in side slopes and inclines. In the push mode, the male/female user walks behind or beside the vehicle, and at least two vehicle components and/or parts thereof are located in a position, relative to each other, different as compared to the position in the ride-along mode. The versatile embodiment variations make it possible to use it as a golf vehicle, as well as a recreational-/, shopping-/, transport-/, industrial-/, construction site vehicle, and as a vehicle for the transport of senior and handicapped persons, for exploration and military purposes, for mowing, as an agricultural vehicle, as gardening appliance and as a child carrier.

An apparatus for converting a cycle-type exercise machine into another type of exercise machine includes a stationary frame structure that attaches to a frame of the cycle-type exercise machine, a pair of swing arms pivotally coupled with the stationary frame structure, and a pair of coupler bars pivotally coupled with the pair of swing arms on one end and rotationally attached to a crank bar of the cycle-type exercise machine on an opposite end.

A bicycle frame including a front portion configured to receive a front wheel assembly; a rear portion configured to receive a rear wheel assembly; and a connecting member connected to the front portion at a first connecting point and connected to the rear portion at a second connecting point, the first and second connecting points being spaced from one another along the length of the connecting member; wherein one of the front and rear portions extends towards and is connected to the other of the front and rear portions at a third connecting point to form a link; wherein the frame is configured so as to allow a distance between at least two of the connecting points to be adjusted; wherein adjustment of said distance increases or decreases the size of the frame.

The present invention relates to a stroller, and provides a stroller including: a seat part, and a seat accommodation part configured to accommodate a seat; a connection frame part including a first connection frame configured to support the seat and to include vertical portions and lateral portions, and a second connection frame formed in a U shape including vertical portions and a lateral portion and configured such that the vertical portions are rotatably connected to the first connection frame; and a bicycle structure including a main frame configured such that the connection frame part is mounted thereon in such a manner that the first connection frame is coupled to the front end thereof and the second connection frame is coupled to the rear end thereof, a front wheel installed under the front of the main frame, and rear wheels installed under the back of the main frame.

A stroller is provided with the ability to removably couple and decouple a seat from the stroller as needed. The stroller can include a stroller frame. The stroller can also include one or more front wheels attached to the stroller frame and one or more rear wheels attached to the stroller frame. The stroller can also include a first seat coupled to the stroller frame. The stroller can include first and second seat attachment housings. Each of the seat attachment housings can include a cavity for receiving a corresponding one of the first and second seat attachment adapters. Each of the seat attachment housings can also include a door cover to prevent access to the respective cavity when not in use. The seat attachment adapters can be coupled to the respective seat attachment housings and a second seat can be coupled to the seat attachment adapters.

A bicycle apparatus with interchangeable front fork is disclosed. The bicycle comprises a frame and a quick release assembly for securing the removable front fork attachment assembly to the bicycle frame's head tube. The interchangeable front fork attachment assembly and quick release assembly allows for the quick interchanging of front fork with varying attachments which utilize different methods to achieve motion.

A balance bike conversion system may include first and second protective inserts, each having an interface adapted to engage opposite ends of a bicycle bottom bracket. A connector may be adapted to connect the first and second protective inserts, and may be adapted to adjust the distance between the inserts, thereby accommodating variability in the width of the bottom bracket. The system may further include adapters to enable the system to be used with bicycles having bottom brackets with different diameters, and may use an elastomeric gasket to accommodate larger bottom brackets. The protective inserts and/or adapters may provide mechanical support to the bottom bracket, thereby protecting it from damage.
