I have an old Dawes Horizon bike in the garage with the bottle
generator that runs on the side of thr rear tyre.

All you need is one of those cycle trainers where the
rear tyre runs on rollers and bobs your uncle.

Lose weight and charge your batteries at the same time.

However, I'm very suppressed that nobody produces a pedal powered efficient
cheap battery charger, since we are all told to take more exercise and most
are not interested in the stats, just the use of energy to keep up our
fitness. I've come across some batteries in a box that have pedals that look
like they may last a few months, but little else.

After all Solar in this country at this time of year is not exactly amazing,
better off with wind power.
