I've already built the bike and have been riding it for two years. It works great. I'm now running a Staton Inc system on the bike. I put a Surly stainless steal chainring on the shift kit. I use a 8 speed 34-11 freewheel on a Staton hub in the rear. I currently have the only motorized bike with a shift kit that shifts gears automatically. Will be posting pictures and videos soon of upgrades recently made. I was just looking for others who've done what I've already done.
