The invention relates to the technical field of bicycles, in particular to a safety protection frame for a bicycle. The safety protection frame comprises first main bodies. Bottom cushions are fixedlyinstalled on the outer surfaces of the bottom ends of the first main bodies; lifting plates are movably installed on the outer surfaces of the first main bodies; clamping sleeves are fixedly installed on the outer surfaces of the upper ends of the first main bodies; protection plates are fixedly installed on the outer surfaces of the upper ends of the lifting plates; supports are fixedly installed on the outer surfaces of the upper ends of the clamping sleeves; foam cushions are fixedly installed on the outer surfaces of the upper ends of the supports; and baffles are arranged on the outer surfaces of the front ends of the first main bodies. The novel safety protection frame for the bicycle is provided with the foaming cushions, slope frames and grooves; the situation that the bicycle isbumped and consequently damaged when placed on the protection frame can be prevented; a user can conveniently push the bicycle into the protection frame; and the multiple protection frames can be better spliced and detached, and better using prospects are achieved.
