Just finished my second build for my first customer...Thanks Kent =)
Kent went with a Nirve frame, 3 speed hub and a Sick Bike Parts shift kit.
The shift kit is DA SHNITZ ...way to go Sick Bike Parts!!!
The shift kit is well worth the money, the bike hauls ASS! Can start from a dead stop in first gear. Second for general cruizin' and 3rd scared the crap outta me. Wouldn't take it to top speed without a helmet!
The shift kit might be a bit difficult for a novice as I had to do some milling on the clutch cover and had to build a custom front motor mount. Front mount also took some shimming to get it right so there wasn't too much or too little slack in the chain from the shift kit to the pedal sprocket. It was a fun build none the less.
Anyway, here's some piccys.
