More than be the explanation of each member of the utility model bicycle drive configuration and associated location thereof, then, again it manipulated narration as back:

The rear wheel type of drive of the utility model bicycle has simultaneously that manpower is trampled and two kinds of motor driven, and its manpower tramples with motor driving mechanism and independently be provided with, to each other and do not interfere with each other characteristic more of the present utility model.

The utility model bicycle is to drive this left side flywheel 34 by these fluted disc 42 these left chains 46 of drive to cause the rear wheel rotation with the manpower when being driving, it is in the process of driving, make the rider can enjoy the effect of motion to the full, so can satisfy the younger generations and the person's of being keen on sports demand.And when the utility model bicycle is desired to change with motor driven, this switch 52 is switched to the position ("on" position) of ON, soon can drive this right side flywheel 35 through this this transmission gear 55 of motor 54 controls drives these right chains 57 and cause the rear wheel rotation by this speed controller 51 of switching, so, the utility model changes with the motor when being driving can obtain the labor-saving effect, being fit to special group uses, the fork or when feeling more tired for stepping with manpower, the changeable driven by power that transfers to is to replace manpower, so that obtain to releive effect.

At last, again that advantage arrangement of the present utility model is as follows:

1, the utility model has the independent manpower that is provided with simultaneously to the type of drive of rear wheel and steps and two kinds of structures of motor driven, it can use for different groups, perhaps replaceable use, for example when the level land, can step to obtain movement effects by manpower, and when running into the upward slope landform, changeable is that motor driven is lost to save the muscle power consumption.

2, the utility model must be opened this master control lock earlier before use, afterwards, can switch this switch position to control this speed controller, and its two roads switch designs has safe and antitheft effect.

3, the utility model bicycle can supply to carry and be equipped with two batteries, and can supply travelling of vehicle commander's distance voluntarily in its electric power of back that once charges.

In sum, the utility model is real in like product to have its progressive practicality, and uses and go up conveniently, again, the utility model there is no identical items and sees publication or public use before application, so, the utility model is real to have possessed novel patent condition, so file an application in accordance with the law.

Only, above-described, only be preferable possible embodiments of the present utility model, so the equivalent structure that every application the utility model specification sheets and claim are done changes, ought to be included in the claim of the present utility model.
