Yeah. It's more a hub really, isn't it. I knew what i meant. It 'should' be an armless crank..

I've looked at that idea briefly, but she just doesn't need to contribute. I suppose it wouldn't be a bad thing for the involvement, but there are other things to consider with that;
For one, the crank is an overdrive - it will be turning around 1.42 times faster than the one on the front, because a 40T front crank will be turning the 28T chainring (his changes my 11-36T freewheel into the equivalent of 8-25T, therefore solving my problem of trying to get a Capreo freehub on an electric motor).
But i could gear her crank back down. Three chains and three BB's though.. well, it ain't gonna be a light bike anyway!
Also, she'll be sat on a long lay-back seat post, partially over the rear wheel, so her feet will be quite far in front of her even to reach the seat post - It'd condition her for using a cruiser bike i guess...

Hmm, this gives me the idea of using the stoker to sit there and just generate electricity with the pedals...
So... now just to shorten the butted frame by some 10ins...
