Has anyone here ever built a bike generator?

I've seen a few projects, especially people trying to live off grid. I wondered if anyone here had had a little fun trying to hook up an exercise bike to a generator? It's something I'd like to do, even if it isn't that practical.

Do you mean a literal bike-powered generator? 

I'm not sure how much electricity you'd make from that or even if you could reliably store it. It probably wouldn't be worth the hassle to be honest.

Not yet, but I have an old bike I never use and an alternator. I don't think It'll be of much practical use, but I want to make one for the fun of it.

Yeah I just want to do it for fun really, though I do wonder weather I could hook it up to batteries in some way to give me emergency power during an outage.

I connected a bike flywheel to an alternator but never found anything to power with it. I tried just hooking it up to a 40W, and blew it :/ I've never made any use of it.

I've been researching for a couple of years, but haven't made the move off grid, yet. I'm looking into a bicycle generator system, and I have two questions:
Is it feasible to recharge a battery bank (say 4 to 6 batteries) using pedal power?
Would one still need to use a charge controller, if such an action would work?
Thank you

The model is made in Shenzhen, the center of the Chinese electronic industry, and has nothing to do with the social network Twitter.
You can even say that they called their products in vain: according to Twitter, finding a social network on the Internet is much easier than a bicycle manufacturer. But this does not affect the driving performance of the bike.
The model is a powerful (350 W) electric bike with a “classic” design, including a motor wheel and a battery pack.

I have no idea about it but i will definitely try out for fun.
