Pedal assisted RTO registrable electric two-wheeled vehicle

A pedal-assisted RTO registrable two-wheeled electric vehicle (20) including a frame, a steerable fork extending from an operative front portion of the frame, a front wheel (11) and a rear wheel (9) mounted to the frame, handle bar mounted on the fork, an accelerator (1) mounted on one side of the handle bar, a seat assembly mounted on the frame operatively behind the handle bar and between the front wheel (11) and the rear wheel (9), a pedal assembly (6) mounted at an operative height above the ground level of the frame between the front wheel (11) and the rear wheel (9), a hub motor (8) mounted on a rear axle of the rear wheel (9) for driving the rear wheel (9), a pedal sprocket (28) fitted to the pedal assembly (6), a chain sprocket (29) fitted to the rear axle, and a drive chain (5) wound around the pedal sprocket (28) and the chain sprocket (29) to assist in driving the vehicle (20) by means of the pedal, said vehicle (20) comprising:

• a compartment formed by panels (12) fitted around an operative front element of the frame behind the front wheel (11) and the handle bar, and operatively in front of the pedal assembly (6) and the seat assembly;
• a swing arm secured between the frame and the rear axle for securing the pedal assembly (6) at the front end and the rear axle at an operative rear end;
• a battery pack (2) housed in said compartment (13), said battery pack (2) configured to deliver power greater than 250 Watts;
• connectors connecting the battery pack (2) to the hub motor (8) to drive the hub motor (8) which in turn drives the rear wheel (9) to drive the vehicle (20) at a top speed greater than 25 kmph;
• a sensing unit fitted in the accelerator (1) for sensing the angular displacement of the accelerator (1) to generate a sensed displacement value;
• a torque sensor (7) fitted in the frame between the pedals, said torque sensor (7) configured to sense the torque applied by the pedal assembly (6) while driving, and further configured to generate a sensed torque value;
• and
• a control module connected to said sensing unit, said torque sensor (7) and said battery pack (2), said control module configured to receive said sensed displacement value and said sensed torque value, and further configured to generate an actuating signal for supplying power from the battery pack (2) to drive the hub motor (8);
• wherein the vehicle (20) can be driven in either a battery mode or a pedal assisted mode, wherein the user's action of pedaling will rotate the chain sprocket (29) and hence the rear wheel for driving the vehicle (20).
