The brake signal generator comprises two strip-like electrodes housed in a strip-like insulation body and the two electrodes are isolated from each other. One end of the insulation body forms a hollow flexible part. The two electrodes are arranged to face each other in a normally open condition in the flexible part. The flexible part is just situated at a force-applying position of the brake grip so that once a rider actuates the brake grip, the flexible part of the brake signal generator is compressed to have the two electrodes shorting each other and sending a brake signal to the vehicle-front controller.
