I like the electric bicycle 20ah battery pack, mine is 15ah like it but does not have the handle on it, that would be a nice option since sometimes switch the battery's between motorized bicycles
I think I have everything else I need to get this thing going.After much debating the issue I decided to order a 48v20ah lithium ion battery pack. It turns out cheap = gotta wait a long long loooooong looooong time. Ah well, something to look forward to this summer! http://www.vpower.hk/product.php?id=346
