Thanks, even with 9000mah ( which I'll probably go for ) I think 30 cells would be nice, 90 AAs and scavenged but robust B&D - rather a headache.
The interesting bits are easier to describe- redundant bb has drill on right, cassette freewheel on left. This has filed 11tooth cog which catches the drive side of the chain. The cranks have 40,55 cogs and 6 jockey wheels behind a guard. With the chain in this position the bike will run with motor and feet stationary on pedals.
Both these innovations appear, surprisingly, to work but there is some friction!
Cheers.
