The invention discloses a controllable bicycle generating device. At least one group of generator is installed in left and right hubs; the generator comprises a stator and two rotors; each stator comprises a coil set formed by annularly distributing multiple coils; the coils are connected with a control circuit after connected in star shape or triangle shape; each rotor comprises a magnet set formed by annularly distributing multiple magnets; and an air gap is installed between the plane where two magnet sets are located and the plane where the coil set is located. Because the coil set for forming the stator has not an iron core, the rotation resistance between the magnetized iron core and the magnet sets is not existent, and the electromagnetism resistance between the coil sets and the magnet sets is not existent while the electromagnetism cutting movement of the coil sets and the magnet sets does not form a closed loop, the load for riding is not increased. While the coil sets and the control circuit form the loop, the electric energy can be directly outputted. The electricity can be selectively generated, and the additional resistance cannot be generated in the state that the electricity is not generated, so the pleasure for riding is improved.
