Can the pedaling energy charge the battery of an electric bike?

Can the mechanical energy of pedaling be stored as electrical energy to be utilized later to run the bicycle automatically? I'm not talking about pure electric bikes that need regular charging, and not even about those that you pedal for a while as the bike stands still and then run it on electric power. I mean can you ride a bike and store the mechanical energy simultaneously? Will it be efficient? If so, then are such e-bikes available in the market, and what are they called so that I may Google for them?

Here's the scenario: I need a bicycle for regular commute, may be even for covering long distances. It's not feasible for a layman to pedal continuously for more than 5 to 10 miles. So I'm looking for a bike that you pedal for sometime, and when you're exhausted, you simply flick a button to make it run on electrical power which has been converted and stored from the mechanical energy of pedaling the bike; and then pedal again and auto-ride again and so forth. Will something like that be technically efficient, since you're moving the bike while pedaling as well as storing your spare energy?

Hope I haven't confused you. Thanks :)

Answer
You will have to pedal extra hard to keep the bike going and to charge the battery. It could be done, but it would be easier and more efficient to pedal a regular (lighter) bike.

Maybe you could use a large solar panel to power the bike

There is already such a motor on the market. The name escapes me right now but it is a hub built into the rear wheel and it costs about $2000... not the Erbike hub motor... I think it is Electricrider or something like that.

To your request, yes, it is possible and a project I am working on right now. No, I can't and won't divulge details but CAN tell you that you'll see it relatively soon and it WILL be expensive- more expensive than a small motorcycle at this point.

By the way... I typically commute 24 miles (one way) to work on a bicycle, no problem. 5-10 mile commute is simple for most committed riders.
