摘要： A kit for reducing handlebar shake in a three-wheel motorcycle with dual front wheels, having a frame, a steering column and a connecting rod that couples the steering column to the dual front wheels, includes a linear steering stabilizer that includes a cylinder member and a piston rod. A portion of the piston rod fits slidingly in the cylinder member. The piston rod terminates in a connecting end. A body bracket is attached to the cylinder member. A first bracket is affixable to the frame and is affixable to the connecting end of the piston rod of the linear steering stabilizer. A second bracket is affixable to a selected one of the steering column or the connecting rod and is affixable to the body bracket attached to the cylinder member. The linear steering stabilizer is damps handlebar shake during operation of the three-wheel motorcycle.

摘要： A rider-propelled vehicle comprising a rear wheel assembly, a front wheel assembly, a dual drive and steering assembly, and a drive train. The rear wheel assembly and the front wheel assembly include 24 inch (ISO 507 mm) or larger wheels. Pedals of the dual drive and steering assembly extend laterally exterior from drive links of the dual drive and steering assembly so that feet of the rider straddle the left and right drive link. A steering train of the dual drive and steering assembly is configured so that the front wheel assembly turns entirely forward of the range of motion of left and right handlebar assemblies of the dual drive and steering assembly.

摘要： A scooter has a foot rest arrangement with a left foot rest surface and a right foot rest surface, a steerable front wheel guide mounted in a head tube so as to be rotatable about a first axis of rotation, and a steering column that can be rotated about a second axis of rotation. The steering column and the front wheel guide are spaced apart from each other and are operatively coupled to each other to transfer a steering movement. The second axis of rotation intersects the foot rest arrangement at an intersection point in such a way that the left and right foot rest surfaces are arranged on either side of the intersection point.

摘要： A front wheel drive bicycle assembly includes a frame that may be mounted for riding. A front wheel is rotatably coupled to a front end of the frame and the front wheel rolls along a support surface. A pedal unit is rotatably coupled to the frame and the pedal unit is selectively pedaled. The pedal unit is in mechanical communication with the front wheel to rotate the front wheel thereby urging the frame along the support surface. A rear wheel is rotatably coupled to a back end of the frame and the rear wheel rolls along the support surface. Moreover, the rear wheel is selectively rotated about a vertical axis for steering. A steering unit is movably coupled to the frame and the steering unit is in mechanical communication with the rear wheel. In this way the steering unit selectively rotates the rear wheel about the vertical axis for steering.

摘要： Improved suspension and steering systems for a trike may include a steering assembly including a power steering assembly coupled to a steering wheel and a front frame assembly. The front frame assembly may include a front plate coupled to a steering hub and two front suspension piston and sleeve assemblies. The front plate and steering hub may be positioned above the front tire so that front tire rotates about an axis that is substantially perpendicular with the surface of the road. This system reduces and/or eliminates problems associated with traditional steering assemblies, such as wheel flop, limited tire life, driver burden, and the like. In addition, the front suspension piston and sleeve assemblies also may be positioned substantially perpendicularly to the road surface to reduce and/or eliminate lateral forces on the trike and changes to the overall geometry of the trike during usage.

摘要： A waterproof end cap for covering and closing an end hole of a bicycle head tube includes a threaded locking base, a locking member, and a sealing cover. The threaded locking base is engaged in the end hole. The locking member has large- and small-diameter portions. The end of the large-diameter portion that faces away from the small-diameter portion has an outwardly extending annular plate. The small-diameter portion is externally threaded, extends into the end hole, and threadedly connects with the threaded hole of the threaded locking to base such that the annular plate is pulled to cover the end hole. The sealing cover is larger than the annular plate in diameter and has opposite first and second sides. The first side is free of water-holding spaces. The second side covers the annular plate detachably through elastic engagement. Water can neither accumulate on nor leak through the sealing cover.
