How does E-bay work?
If I had known some one had a spare motorised Joey I'd have been very interested. I was looking to stick a Nano motor on one back in May. I've only put of the building of what would be my ideal e-bike, ( low cross bars and sporty handling for a short arsed Moulton Fan), because I ended up buying a whole bike shop.
The trick with the Bionx to get max range is to change down from maximum assist to level 3 ( one to one ), or lower on hills and let the gears and the low speed power requirements do the work, similarly to the way Cytronix advise. I know it sounds a bit cock-eyed but it seems to work well, I've tried the same technique on a few motors in the past were I was worried about current drain on batteries, throttling back on hills to find a comfortable medium and climbing slow(er) but sure, tortoise fashion.
