CONSTITUTION: A tricycle with double driving force comprises a first frame(10), a first handle(20), a first wheel(30), a first saddle(40), a first driving unit(50), a first operation unit(60), a second frame(70), a second handle(80), a second wheel(90), a second saddle(100), a second driving unit(110), a second operation unit(120), a rotating unit, a rear wheel mounting unit(140), a rear wheel(150), a power operation unit(160), and a reinforcing frame(170). The first handle is coupled to the first handle connector(11) of the first frame. The first front wheel is composed of a first front wheel coupler(31) and a first wheel(32). The first driving unit is composed of a first pedal(51) and a first gear(52). The first operation unit is composed of a second gear(61), a first rotary coupling shaft(62), and a third gear(63). The second gear is rotated when the first gear is rotated. The thrid gear is rotated when the first rotary coupling shaft is rotated.
