Yes, and while cycling, you can actually do some other things. Reading, watching TV, etc. Although, looking at first world countries, and how society is working, having solutions which force exercise on us would probably be extremely beneficial.

Wouldn't you need to find a TV that doesn't run on electricity first?

Small electronics draw relatively little power. You can run a small LCD/LED TV (or radio) off solar PV and a small (regulating) battery. Large power (and heat) loads require far more (and more reliable) energy. Tapping into human energy is an option, though net net it's still fairly inefficient.

ha! good point.

Although I was kind of thinking that even without the electricity, it's a benefit.

Or alternatively, you could get 20 of these, all facing each other and be sociable. Or if you have some electricity in a town, get all of them in a hall, and play movies. :-)

Well, electricity is made out of rotating things if you strap a magnet to them somewhere ;).

If you're powering a washing machine and a TV by pedaling, I'm not sure you'll last a full cycle ;)

smartphone/tablet - and solar powered battery charging. No need for a big screen.

You could be coding in Java...

Then I wouldn't get the laundry done.

Exercise is only lacking if most of your daily chores and transport are handled by machines, which is not the case here.
