New visitor here, so if its in an archive, sorry.
 Is there a relatively cheap device that can turn pedal power into a charger
for batteries for phones or other devices? All this keep fit going on seems
so wasteful.

or Google "pedal generator".

It looks like this simple project separates the dreamers from the doers.

 Yes, I know about that, but this is not in the US, I want one in the UK, it
will cost a packet to import the bits.

If I were going  to make a pedal generator I would use the motor and gearbox
assembly from an electric wheelchair.  The in-line ones would work better
than the right angle ones. I have a set like these:

only mine are from an Invacare.

The guys who assembled two bike generator to power an offgrid concert
which I helped at used a standard shopping, lady's bicycle. The back
wheel was held clear of the ground by a triangular frame attached to
the back axle. A 200W DC motor from a child's 24V electric scooter was
held against the rear tyre and driven by friction. This fed via a
rectifier into 2 1Farad capacitors and power was taken off these.
There were three leds across the capacitors to indicate correct
voltage. It was steady work to maintain a 60W output and I just about
managed to peak at 200W.
