A motor-less leg-powered curved treadmill produced that allows people to walk, jog, run, and sprint without making any adjustments to the treadmill other than shifting the user's center of gravity forward and backwards. A closed loop treadmill belt running between front and rear pulley rollers is formed with a low friction running surface of transverse aluminum, wooden, plastic, rubber or carbon fiber slats attached to each other in a resilient fashion. Since an essential feature of treadmill is the concave shape of the running surface of belt in its respective upper portion, the treadmill configurations insure that this shape is maintained during actual use. These configurations prevent the concave upper running surface portion from being pulled taut into a flat shape between the front and rear pulley rollers.

A two-wheel, self-balancing vehicle comprises a first wheel and a second wheel, spaced apart and substantially parallel to one another; a foot placement section connecting the first wheel and the second wheel; a set of position sensors in the foot placement section, the set of position sensors configured to generate inclination angle signals and velocity signals of the two-wheel, self-balancing vehicle; a first gravity sensor and a second gravity sensor in the foot placement section, the first gravity sensor and the second gravity sensor configured to generate weight signals and gravity angle signals. In addition, the two-wheel, self-balancing vehicle comprises a control logic configured to output control signals that control the movement of the two-wheel, self-balancing vehicle in response to the inclination angle signals, the velocity signals, the weight signals, and the gravity angle signals.

A cargo cycle includes a frame, a plurality of wheels and a rider seat assembled on the frame, and a passenger compartment supported on the frame. The passenger compartment includes a plurality of side walls and at least one passenger seat disposed inwards of the side walls. The passenger seat has a plurality of reclining positions reclined at different angles relative to the side walls. The passenger seat includes a back support and a seat portion. The back support has a folded orientation in which it is folded down parallel to the seat portion and forms a cover of the passenger compartment.

The disclosure extends to systems, methods, and devices for providing a pre-packaged frozen confection. The system includes a vehicle comprising three wheels, an ice chest secured to the vehicle, and a toppings dispenser attached to at least one of the vehicle or the ice chest. The toppings dispenser includes at least one receptacle configured for holding a liquid topping, a housing attached to at least one of the vehicle or the ice chest, and a spout in fluid communication with the receptacle.

A cargo box has a cargo box body and a tailgate. The cargo box body has two walls, a floor, an opened side, at least one slot defined in the floor, and at least one tab extending from at least one of the walls. The tailgate is selectively pivotally connected to the cargo box body and has at least one tailgate tab extending from a bottom thereof and being received in the at least one slot and at least one recess defined in a side thereof. The at least one tab overlaps a portion of the tailgate when the tailgate is closed thereby preventing opening of the tailgate. The tailgate is generally vertically slidable to align the at least one recess with the at least one tab thereby permitting opening of the tailgate. A vehicle having the tailgate and methods of opening and removing a tailgate are also described.
