The invention discloses a children bicycle balance wheel capable of being disassembled and assembled without tools, and relates to the technical field of children bicycles. The children bicycle balance wheel capable of being disassembled and assembled without the tools comprises a fixed seat which is connected with a bicycle frame, a support and a balance wheel, the support is provided with a bend, and the balance wheel is fixed at one end of the support; the fixed seat is provided with a transverse lock tongue hole and a vertical support hole which is communicated with the transverse lock tongue hole, the support hole is provided with a polygon hole which is matched with a polyhedron at the end portion of the support, and a lock tongue groove is formed in the polyhedron; the lock tongue hole is provided with a lock tongue, a spring and a hollow bolt, one end of the lock tongue is matched with the lock tongue groove, the other end of the lock tongue is provided with the spring and a hollow screw cap, and the hollow bolt is matched with the orifice of the lock tongue hole in a threaded mode. When normal assembly is conducted on the balance wheel, the support is inserted into the support hole from bottom to up, and the end portion of the support squeezes the lock tongue outwards till the lock tongue automatically falls into the lock tongue groove to complete the fixation under the action of the spring; when the support needs to be taken down, the hollow bolt needs to be taken out to make the lock tongue break away from the lock tongue groove; if inverted assembly is conducted on the balance wheel, the support needs to be inserted into the support hole from top to bottom, the balance wheel can be fixed on the bicycle frame, and the children bicycle balance wheel is convenient to assemble and carry at any time.
