The invention discloses a speed limiting protection device for a child bicycle, which comprises a frame. A brake detection mechanism is arranged at the upper part of the frame; the brake detection mechanism comprises wheels arranged below the frame; two brake pads are arranged on the upper portion of the wheel in a bilateral symmetry mode; a left brake rod is fixedly arranged on the end face, awayfrom the wheel, of the brake pad on the left side; a right brake rod is fixedly arranged on the end face, away from the wheel, of the brake pad on the right side; the left brake rod and the right brake rod are connected with the frame through pins; the right end of the left brake rod is fixedly connected with a brake cable; the brake cable sequentially penetrates through a pressure sensor fixedlyarranged on the upper end face of the right side of the left brake rod and the right side of the right brake rod. A pressure spring is fixedly arranged between the pressure sensor and the right brakerod; the bicycle speed when a child rides a bicycle can be automatically detected, when the bicycle speed exceeds a certain specific value, the brake part is started, brake deceleration is achieved,meanwhile, the working state of the brake can be detected, and when brake failure is found, the brake part is started, and brake is completed.
