The invention relates to a forward-turnover preventing bicycle. The bicycle comprises a bicycle rack, a front fork rack, a front wheel, a rear wheel, a saddle, a handlebar and a braking assembly, wherein the braking assembly comprises a front brake handle; the front brake handle comprises a handle support, a handle stem, a rotating shaft and a connecting rod; the handle support is mounted on the handlebar; one end of the connecting rod is connected the handle support through the rotating shaft, and the other end of the connecting rod is connected with the handle stem. The forward-turnover preventing bicycle is characterized by further comprising an electromagnetic lock, a control circuit board, a speed sensor and a battery, wherein the electromagnetic lock is mounted on the handle support; a hole is formed in the handle support; the electromagnetic lock is provided with a spring bolt stretching out of the hole; the spring bolt is positioned on one side of the connecting rod; the stretching and shrinking direction of the spring bolt is parallel to the axis of the rotating shaft; the electromagnetic lock and the speed sensor are electrically connected with the control circuit board; the control circuit board, a battery lock and the speed sensor are electrically connected with the battery. The bicycle disclosed by the invention can avoid the situation that because a learner incorrectly controls gravity and urgently brakes the bicycle by utilizing the front brake handle, and the bicycle turns over forwards; therefore, a mountain bike has a safe mode, and the safety performance of the bicycle is improved.
