Abstract: An electric vehicle (10) comprising: a frame (11); an electric battery module (24) comprising at least one battery connected to the frame; an electric motor (20) receiving power from the battery module (24); a transmission system (80) provided with a transmission casing (208B); said electric motor (20) is closely coupled to the transmission system (80) and is mounted on the transmission casing (208B); and a rear wheel (84) receiving power from the electric motor (20) through the transmission system (80) and said rear wheel (84) is connected to the frame using a rear suspension system; wherein the rear wheel (84) is connected to the frame (11) using said casing (208B) forming a part of the rear suspension system.

Abstract: A frame for an electric vehicle (10) comprising: a head pipe (12) and at least two rear tubes (13) extending rearwardly from the head pipe (12); an electric battery module (24) used as a power source for powering the electric vehicle comprising at least one battery located below rear portion (13B) of said rear tubes (13); a protective frame structure (23) for securely mounting said battery module (24); wherein said protective frame structure (23) is fixed to said rear tubes (13) of said frame and provided substantially centrally and downwardly of said vehicle (10).

Abstract: A transmission system for a scooter has a gear train assembly and a gear shifting mechanism. The gear train assembly has an input shaft, which is provided with an integral gear, an intermediate shaft, an output shaft, an input fork, an intermediate fork, an output fork, three dog gears, four slotted gears, and gear. The system may be employed for manually or automatically changing gears in a scooter to enable the vehicle to be driven with different speeds and with varying load conditions. The system utilizes a compact three-shaft system designed to achieve required gear ratio steps in a positive efficient manner.
