ことを特徴とする変速機付フリーホイールハブ。A sprocket wheel having a hub shaft provided with a sun gear, a hub body rotatably fitted onto the hub shaft, a ratchet pawl fitted onto the hub body and provided on the outer periphery of the hub body; A ratchet located between the internal teeth provided on the inner surface of the sprocket wheel and the sun gear to rotatably support the planetary gear that engages with both, and is formed on the inner surface of the hub body and transmits power at high speeds. The hub includes a ratchet having a ratchet pawl that engages with the teeth, and an operating ring that changes the speed of the hub body to high or low speed by engaging or separating the ratchet pawl of the sprocket wheel from the ratchet teeth on the outer periphery of the hub body. This operation ring is slidably inserted into the outer periphery of the main body, and this operating ring has a conical shape that is inserted between the ratchet teeth on the outer periphery of the hub body and the ratchet pawl of the sprocket wheel by shifting in the direction of the rotation axis, and releases the engagement between the two. A freewheel hub with a transmission characterized by a ring-shaped operating piece protruding from it.
