The Dual-Energy Bicycle is the only product of its kind that can be altered to be used in three different and unique ways to train all regions of the body. In addition to these three operating modes, this unprecedented bike is uniquely designed with an adjustable primary seat, an adjustable chest support, and a greater front wheel angle. Furthermore, the Dual-Energy Bicycle is carefully crafted with durable materials to ensure long term sustainability and complete functionality based on consumer preferred use and/or based on the terrain being explored.

A vehicle for transporting persons and/or goods, having at least one frame which includes of at least one frame element which extends substantially parallel or obliquely to the longitudinal direction of the vehicle, at least one wheel carrier which can be detachably secured to the frame element and which, together with the frame element, forms a receiving region between the wheel carrier and the frame element. The wheel carrier and the frame element are spaced apart from one another at least in sections so as to form a cavity. The frame also includes at least one wheel unit which includes a wheel and can be fixed or is fixed in a rotatably mounted manner at least in sections in the receiving region between the wheel carrier and the frame element.

Bicycle comprising a head tube (3), a down tube and a steering tube. The head tube comprises a cable passage (14) connecting the interior of the head tube with the interior of the down tube. The steering tube (16) engages an upper bearing (18) and a lower bearing (19) within the head tube. The upper bearing is below the cable passage. Cables (12) enter the head tube (3) at a top end of the head tube and leave the head tube via the cable passage (14) to the down tube (4).

The present disclosure provides a scooter including a wiring structure. The wiring structure is fixedly connected to the handle assembly, the frame assembly, and the front wheel assembly, respectively. The second tubular member sleeves a periphery of the first tubular member and an axis of the first tubular member coincides with an axis of the second tubular member. A first opening and a second opening are respectively provided on the first tubular member and the second tubular member, and the first opening is opposite to the second opening. One end of the third tubular member is fixedly connected to the second tubular member along the second opening. When the first tubular member is rotated relative to the second tubular member there is a gap. The scooter of the present disclosure has the advantage of smoothly guiding the wires without damaging the wires.

An bicycle includes a frame assembly having a head tube and a fork having a steerer tube mounted for rotation in the head tube. The bicycle further includes wheels supporting the frame assembly, and a component line positioned at least partially in the head tube and between the head tube and the steerer tube. The bicycle further includes a protector positioned in the head tube and separating the component line from the steerer tube.
