The invention relates to a combined pawl speed changer. The combined pawl speed changer comprises a power input piece, a center shaft, a hub, a first automatic gear shifting mechanism, a second automatic gear shifting mechanism, a first planet speed changing mechanism, a second planet speed changing mechanism, a first overrunning clutch and a second overrunning clutch. The first automatic gear shifting mechanism comprises a first pawl piece frame, a first ratchet wheel, a second ratchet wheel, a first pawl piece, a first balance weight piece, a linkage pawl piece and a first balance weight piece. The first balance weight piece is in linkage connection with the linkage pawl piece. A first pawl part is arranged on the first pawl piece; a second pawl part is arranged on the linkage pawl piece; the first pawl part and the first ratchet wheel form a first meshing pair, the second pawl part and the second ratchet wheel form a second meshing pair, and when one of the first meshing pair and the second meshing pair is meshed, the other one is disengaged, so that the speed ratio between a low-speed gear and a medium-speed gear of the speed changer is more reasonable, and riding is easier.
