Im thinking of doing a Hub conversion on one of my bikes. FWIW here is a link to a thread discussing the best value kits on the market:

Be sure to check out the links, lots of good info at the goldenmotors forum!
Couple of good leads on (relatively) cheap LiOns too.
Now, should I put this on my beach cruiser, or my barhopper chopper...
