Abstract: A cable brake for a bicycle has a frame and a seat. The frame has a spire formed at a top thereof. A hole is defined beneath the spire for two first cables extending therethrough. The seat is received in a chamber defined in the frame, and has a channel defined therein and a first fastener and two second fasteners provided therein. The first cables are extended in the seat and secured by the first fastener, and connected with two brake levers. Two second cables are extended in the seat through a bottom surface of the frame and secured by the second fasteners respectively. The second cables are connected with two braking means respectively. The seat is suspended in the frame by the first and second cables.

Abstract: An elliptic gearing for a bicycle has an elliptic driving gear rotatably mounted at a bottom-front end of a frame of the bicycle by a crank axle extending through the frame. A driven gear is rotatably mounted at a bottom-rear end of the frame. A chain connects the elliptic driving gear and the driven gear. Two cranks extend oppositely and are respectively mounted at two ends of the crank axle. The cranks are parallel to the maximum diameter of and perpendicular to the minimum diameter of the elliptic driving gear. Two pedals are pivotally mounted on distal ends of the cranks respectively. An adjusting device is mounted beneath the driven gear and connected to the driving and the driven gear by the chain.

Abstract: A shock absorber for a scooter has a front shock absorber which is applied to a front wheel of the scooter and a rear shock absorber which is applied to a rear wheel of the scooter. When the scooter is ridden over a bumpy surface, both the shock absorbers minimize shocks to the scooter emanating from the bumpy surface.

Abstract: An auto-carriage has a first frame and a second frame pivotally connected to the first frame so that both the front wheels and the rear wheels of the carriage are able to maintain engagement to the ground at all times. Furthermore, a pair of unidirectional bearings are provided to distal ends of an axle, such that the carriage is able to change the moving direction easily. A first linkage connected to a secondary linkage through a universal joint enables the steering force of a user to convert to the driving force to the front wheel bracket so as to change the moving direction of the carriage.
