The present invention is generally directed to a swing arm configuration and, more specifically, a swing arm that is supported by a shaft of a motor, such as an electric motor of a motorcycle. The configuration includes a swing arm assembly that is supported by a shaft of a motor at one end and a rear axle at the other end. Advantageously, the shaft of the motor may be a structural component of an electric motorcycle and serve as the swing arm pivot as well as the drive shaft.

A superefficient box beam bicycle structure (SBBBS) having a box section, a right triangular section and a left triangular section. The right and left triangular sections are either integral with the box structure, or the triangular sections are attached to the box structure by riveting, bonding or welding. The box structure is preferably made of a sheet material and the parts that comprise the box structure are attached together by riveting, bonding or welding. The SBBBS interfaces with conventional bicycle components to function as a lightweight, strong bicycle frame. Additionally, the SBBBS can be manufactured as a one-piece design, or can utilize a hybrid construction design with an internal structure and reinforcing members at areas of high stress.

A bicycle frame with a hidden battery pack has a tube member and a battery pack. The tube member is hollow and has a peripheral surface, a receiving space, and a replacement opening. The receiving space is formed inside the tube member. The replacement opening is defined in the peripheral surface of the tube member and communicates with the receiving space. The battery pack is mounted in the receiving space and has multiple batteries. Each two adjacent batteries of the multiple batteries are connected to each other and are able to rotate relative to each other. Each battery of the multiple batteries is capable of being rotated or swung to pass through the replacement opening.

A cycle frame may include a first set of plates and a plurality of frame beams attached between the first set of plates using removable fasteners.

The invention relates to a vehicle, in particular a lightweight vehicle. The vehicle can be converted from a driving configuration to a seating configuration by reducing the distance between a front wheel structure and a rear wheel structure.

The present invention relates to a saddle-riding vehicle, preferably an endurance-type vehicle. The vehicle comprises a steering tube to which a steering assembly that controls a front wheel is rotatingly connected. The vehicle comprises a frame comprising a central part (12) to which is hinged a first end (8A) of a fork (8) which also comprises a second end (8B) rotatingly connected to a rear wheel (4). This frame also comprises a front part (15) extending between the steering tube (11) and said central part (12), wherein this front part (15) comprises a first frame side (15A) and a second frame side (15B) separated in the direction of the width of the vehicle and made of a first metallic material. The vehicle according to the invention is characterised in that it comprises at least a pair of connecting plates (16A-16B) wherein a first plate (16A) connects said engine assembly (2) to said first frame side (15A) and a second plate (16B) that connects said engine assembly (2) to said second frame side (15B). These plates (16A-16B) are made of a second metallic material having a modulus of elasticity lower than that of said first material constituting said frame sides (15A,15B) of said front part (15) of the frame (10).

A manufacturing method of a bicycle unit has the following steps. In a pressing step: press metal sheets to form casing parts being overlappable. In an abutting step: abut the casing parts to form an abutting line. In a connecting step: connecting the two casing parts along the abutting line to form a motor mount prestructure having side plates and a motor-installation space formed therebetween. A prestructure of a bicycle frame is thereby made. In a motor mount forming step: cut the two side plates of the motor mount prestructure in compliance with a pre-determined motor system so as to form a bicycle frame unit with a motor mount.

A motorcycle, or saddle type vehicle, is disclosed that may have at least one seat and at least two wheels, at least one hub electric motor. A large dry storage compartment may be positioned between the rider and steering mount. A rechargeable battery and battery management system may be located below the storage compartment in a battery housing, where the battery housing may be a structural component of the chassis. A rear electronics housing may be attached to and located behind the battery housing, and may contain major electrical components such as electric motor controller and contactors. Two structural members, or frame side rails, may form sides of the storage compartment and extend between the electronics housing and steering mount. The electronics housing may also connect to the battery housing such that the battery housing reinforces and strengthens the chassis, or structural frame. A secondary storage compartment may be located under the seat. Additionally, the storage compartments may have electronic locking mechanisms that are activated via a wireless connection to a remote electronic device.

A vehicle includes a frame including a lower frame portion made from a first material and an upper frame portion made from a second material different from the first material, a center of gravity of the upper frame portion being above a center of gravity of the lower frame portion, at least one front suspension system connected to the lower frame portion, at least one front ground engaging member connected to the front suspension systems, at least one rear suspension system connected to the lower frame portion, at least one rear ground engaging member operatively connected to the rear suspension system, a power pack connected to and supported by the lower frame portion, a seat connected to and supported by at least one of the upper frame portion and the lower frame portion, and at least one body panel connected to and supported by the upper frame portion.
