Abstract

The invention provides an electric bicycle capable of realizing low gravity, comprising a down frame (18) extending from a head tube (11) downwards and towards the back of the body; a lower frame (19) extending backwards towards the back of the body from another end of the down frame (18); a seat tube (22) connected with the back end of the lower frame (19) by a connection component (20) and extending upwards; a seat (23) arranged on the upper end of the seat tube (22); a power unit (30) for driving the back wheel (24) and provided with a motor (27) and a pedal (28) for the occupant; an accumulator (39) for supplying the electric power for the motor (27), characterized in that: the lower frame (19) is rectangular viewed from the section and the accumulator (39) is housed in the lower frame (19). The accumulator (39) as the weight matter is housed in the lower frame and the gravity of the electric bicycle (10) is lowered.

Description

technical field [0001] The present invention relates to an electric two-wheeled vehicle whose drive source is an electric motor. Background technique [0002] There is known an electric two-wheeled vehicle in which a pedaling force is detected when a passenger steps on a pedal, and an electric motor is operated by detecting the pedaling force (for example, refer to Patent Document 1( figure 1 )). [0003] As in Patent Document 1 figure 1 As shown, in an electric motorcycle (1) (numbers in parentheses indicate symbols described in Patent Document 1. The same applies hereinafter), a power unit (4) is provided near the connection member (15). The power unit (4) has an electric motor powered by a battery (16). The battery (16) is arranged to extend longitudinally from above the power unit (4) toward the seat (2). [0004] However, the center of gravity of the electric motorcycle (1) tends to be high because the battery (16) as a weight is arranged to extend in the longitudin...
