Electric vehicle

An electric vehicle comprising:

• a frame;
• an electric battery module including at least one battery connected to the frame;
• an electric motor receiving power from the electric battery module;
• a transmission system closely coupled to the electric motor;
• and
• a rear wheel receiving power from the electric motor through the transmission system, wherein the electric motor and the transmission system are located on a same side of the rear wheel, and further wherein the rear wheel is connected to the frame using a swing arm, the swing arm:
• functioning as a transmission casing by encompassing the transmission system and forming an integral part of the transmission system;
• having a provision for externally mounting the electric motor towards an opposite side of transmission system;
• extending horizontally such that one end of the swing arm mounts on the rear wheel and the other end is pivotally mounted on the frame forward of a rear wheel to form a structural element of a suspension system of the vehicle;
• and
• wherein the transmission system is a single speed, multi stage transmission, comprising an input shaft connected to an output shaft of the electric motor through a first gear pair, and the input shaft of the transmission is further connected to an output shaft of the transmission system through a second gear pair, and further wherein the output shaft of the transmission system is connected to the rear wheel of the vehicle for transmitting the torque.
