<p>This two-wheeled electrically assisted vehicle (2) comprises a frame (4), a front wheel and a rear wheel (6), said rear wheel (6) comprising a hub (60) rotatable around a rear axle (40) of the frame (4), a primary torque source (8) which transmits a torque to the rear wheel (6), an electric motor (10) adapted to transmit an assistance torque to the rear wheel (6) and an infinitely variable transmission system (12). On a kinematic chain for driving the rear wheel (6), the electric motor (10) and the infinitely variable transmission system (12) are mounted between the primary torque source (8) and the rear wheel (6), and wherein the infinitely variable transmission system (12) is mounted between the electric motor (10) and the rear wheel (6).</p> |
