A derailleur for hybrid

The utility model provides a derailleur for hybrid, includes first power input piece, the 2nd power input assembly, power input shaft and passes through gear driving chain gear transmission coordination's power output shaft with power input shaft, a first power input transmission sets up inputs first power in power input shaft and with the mode that power can be surmounted, the 2nd power input assembly includes the second power input gear I of one of them driving gear of conduct in the gear driving chain at least, second power input gear I is with power input shaft transmission coordination and input second power, the motor of avoiding mixing in double dynamical need pass through reducing gear and transition gear, guarantees compact structure, and occupation space is less in the installation, reduces spare part material cost, alleviates the dead weight, specially adapted motor tricycle, and the driven gear that second power passes through the derailleur in simultaneously two power take off assemblies can guar
