I used to own a few sinclair Zikes - they had 20 1.2v D sized batteries
in the frame.

Incidentally I own and run www.c5alive.co.uk and I often get asked if
the Sinclair C5 will charge the battery whilst rolling down a hill. Even
if it did (which it doesn')  the limiting factor is how much charge/time
you would theoretically get back into the battery going down a hill.
Find a hill that takes a couple of hours to go down and you may be able
to get some charge into the battery - but I wouldnt like to pedal up to
the top ! (Ironically I seem to recall a road in NZ from napier to
auckland via gisborn has a road on the side of a gorge that seemed to
take about half an hour to go down by car so it would probably be a good
example to charge a battery but i have otherwise never come across
another hill of such proportions)

I am emigrating from the UK to NZ at the end of Nov, I'll be bringing a
couple of C5's with me I have 10 presently ! Sad eh ! Anyhow I'm also
selling C5alive.co.uk
website/stock/suppliers/goodwill/diagrams/information etc if anyone is
interested (afterall mail order to the UK from NZ may be a bit too 
expensive for most of my customers LOL)

Cheers

Chris
