A body for an electric two-wheeled vehicle is proposed. More particularly, proposed is a body for an electric two-wheeled vehicle in which materials of different types are stacked to be light in the weight of the vehicle body, and space receiving a battery is defined to protect the battery and facilitate installation thereof. The body for an electric two-wheeled vehicle includes a frame part having a space part formed in a center part thereof, wherein in the frame part, first and second material layers of different types are alternately stacked to be coupled to each other such that the first and second material layers form multiple layers.

A drivetrain assembly comprises a bottom bracket shell defining a front axis, a dropout defining a rear axis, a chainstay member attached to the dropout and the bottom bracket shell, a front sprocket and a rear sprocket, and a chain or belt including a bottom section extending from a first contact point between the chain or belt and the front sprocket to a second contact point between the chain or belt and the rear sprocket. The chainstay member fixes the dropout relative to the bottom bracket shell, such that a chainstay length is non-variable, and such that the chain or belt has a predetermined tension defined by a midpoint of the bottom section being vertically displaceable only by a maximum vertical extent within a predetermined range upon application of a predetermined load at the midpoint of the bottom section.

A tilting vehicle includes a frame unit, a tilting mechanism and two front wheels. The frame unit includes a head tube extending generally along an up-down direction, and a main frame detachably connected to the head tube. The tilting mechanism includes one crossbar pivotally connected to the head tube and extending along a left-right direction, and two connecting rods extending along the up-down direction, being opposite to each other along the left-right direction, and being pivotally connected to opposite ends of the one crossbar, respectively, such that the connecting rods are movable along the up-down direction relative to the head tube. The front wheels are rotatably mounted to the connecting rods, respectively.

The present invention relates to a bicycle frame (100) and a method of production thereof. In one embodiment the bicycle frame (100) comprises a first hollow tube part (10) comprising a first thermoplastic fiber reinforced composite comprising a thermoplastic matrix and an embedded structure of fibers (11, 12); and a second hollow tube part (20) comprising at least a first fiber reinforced shell part (21) and a second fiber reinforced shell part (22) each comprising a second thermoplastic fiber composite. According to the method a fused interconnect is formed having an overlap (30) between the first hollow tube part (10) and the second hollow tube part (20), wherein the embedded structure of fibers (11, 12) of the first hollow tube part (10) at the overlap (30) crosses an overlap (30) between the hollow tube parts (10, 20).

A method for thermoforming a bicycle frame component includes the steps of: (A) preparing first and second casings both made of a thermoplastic material, the first casing having a first abutment surface, the second casing having a second abutment surface; (B) preparing a reinforcing unit; (C) abutting the first and second abutment surfaces against each other, and then placing the reinforcing unit at a junction of the first and second casings; and (D) thermally bonding the reinforcing unit to the first and second casings such that the first and second casings are joined to form the bicycle frame component. A bicycle frame component is also disclosed.

A vehicle includes a body having a first part and a second part, which is moveably coupled to the first part. The vehicle further includes a pedal assembly having a first component coupled to the first part and a wheel assembly having a second component coupled to the second part. The vehicle further includes an extendable drive shaft having a first member and a second member. The first member is coupled to the first component and the second member is coupled to the second component. The vehicle further includes a locking mechanism having a locking member coupled to the first part and the second part of the body. The locking member, in an unlocked position, unlocks the second part from the first part to allow the second part to move over the first part, which may cause a change in a length of the extendable drive shaft.

A rod piece connection device, comprising: a first connection piece and a second connection piece. The first connection piece includes a first rod piece connection end and a first joggle joint end opposite to the first rod piece connection end. Wherein, the first joggle joint end includes a protrusion head tongue portion and a neck portion. The second connection piece includes a second rod piece connection end and a second joggle joint end opposite to the second rod piece connection end. The second joggle joint end is located corresponding to the first joggle joint end for them to form into a joggle joint. The second joggle joint end includes a protrusion bottom groove portion and a pillow portion. Wherein the protrusion head tongue portion is disposed corresponding into the protrusion bottom groove portion, and the neck portion is located corresponding to the pillow portion.

A system for a motorized vehicle having a frame and a wheel rotatably coupled to the frame has a first fender housing mounted to the frame, a second fender housing coupled to the first fender housing so that a volume is defined therebetween and an electronic component disposed in the volume.
