waiting for my replacement neo to come in (mine is now to the point of unridable, mores the pity, so just waiting for the new one) and idly giving my mind to the possibility of ebiking hte monster bike i have sitting around.

its a hooj thing with 36 inch wheels (coker monster if anyone wants to take a look) and has always been something different to trundle about on, however i think it will become something never trundled about on unless i motorise it.

guessing i'd need to use a crank drive of some kind? but i'm a bit lost from there (sorry, a quick scan of the forum didnt really help) any thoughts/advice gratefully recieved

(of course i'll probably never do it, but i have to find something to do when i should be working! :) )

I think that new bafang crank drive would be the one for this. Would need some modification of the chain guard perhaps. Tricky bit would be getting the size of the front chainwheel small enough for the gearing to be right due to the large wheel circumference. Could perhaps increase the size of the rear sprocket to compensate
