A forward and backward speed adjusting handle for an electric vehicle includes a bar handle, a fixing element formed by a handle seat, and a twist grip. A leftward rotation spring and a rightward rotation spring are provided between the fixing element and the twist grip. The leftward rotation spring drives the twist grip to rotate counter-clockwise relative to the bar handle; the rightward rotation spring drives the twist grip to rotate clockwise relative to the bar handle. Under a common effect of the two springs, the twist grip is at an idle position. When the twist grip is applied with an external force, the twist grip is rotated away from the idle position. A Hall-effect sensor and an arc permanent magnet are respectively provided on the twist grip and the fixing element. When the twist grip is rotated, the Hall-effect sensor moves relative to the arc permanent magnet.
