Jim from Jacksonville, FL. Grubee 66 kit on a nasbar MTB frame with 7 speed internal hub with disk brake. King's Top hat. Front MTB suspebsion fork. As soon as I toss the CNS carb it should work great. And to think I paid more for the kit because of that thing! I have also built an E bike from amped bikes. Disk brake is awesome. Don't even need a front brake. Some slight modification on the top hat to seat it on the sturn archey hub and some slight mods to the disk brake mounting points on the frame to get the disc brake and drive sprocket to all fit and work on the left side. Will post pics later. Thanks for the info on CNS carbs. Anyone want to buy mine?
