Bike generator?

Question

does anyone know how i can make a bike generator

Answer 1

go buy a bike with generator

Answer 2

You don't want to try to make one; you can buy them quite inexpensively.  But I would never consider using one: I want to spend as little of my energy as possible riding a bike, and that means that bike lights run on batteries.

Answer 3

It is not clear whether you want a generator to power a light on the bike or to power other devices much as one would use a hand crank generator to power a computer.

I agree with an earlier comment that you would use a LED light powered by a battery if that is an option. If you use a rechargeable battery it can have a solar cell to keep it charged up.

Or use a hand crank  dynamo and forget about the bike.

If you really plan to power much else with a bike, consider instead using solar power with a car battery for storage. It can produce more power than your pedals can.
