That is not the point how much energy are useing the drilling machine and the light bulb. Do not mind this for now. The main benefit of this design is that the magnets are useing both their sides producing electric power. As usual, designs of many generators are useing only one side of magnets.

...I never can ride longer than the battery getting empty ~ 25-30 km... I try to explain this phrase, - I can ride longer than the battery getting empty, but I do not like too long bicycle trips. The bike can ride longer than 30 km.

Yes, I can.
