Damn impressive when you realize how hard it is to produce any power that way.

Standard hub dynamo will put out 6 volts, 3 watts.

Random 4k tv I found online has a listed typical consumption of 57 watts.

You'd need twenty of these bikes hooked up to some kind of rectifier that can convert the power into something usable.

A hub dynamo is designed to take as little power out of the wheels as possible to not slow down there bike too much.

If you put a bigger dynamo on a stationary bike you can get much more power out of it, between 50 to 100W.
