Provided are a forward and backward speed adjusting handle for an electric vehicle that can be rotated forward and backward so as to control the forward and backward movement of the electric vehicle. The invention comprises a rotating handle and a fixing element consisting of a handle bar and a handle base; provided between the fixing element and the rotating handle are a left-rotating spring and a right-rotating spring; the left-rotating spring enables the rotating handle to rotate counter-clockwise with respect to the handle bar, and the right-rotating spring enables the rotating handle to rotate clockwise with respect to the handle bar; under the effect of both left-rotating spring and the right-rotating spring, the handle bar is in a reset position; when an external force is applied on the rotating bar, the rotating bar can rotate clockwise or counter-clockwise from the reset position; a Hall effect sensor and an arc-shaped permanent magnet are oppositely arranged separately on the rotating-bar and the fixing element without touching one another; when the rotating bar rotates, the Hall effect sensor moves relatively to the arc-shaped permanent magnet, detects the different positions of the arc-shaped permanent magnet, and outputs corresponding different signals.
