I put my wife's Dahon Briza with the TSDZ2 up for sale. If it doesn't sell very soon I'm going to pull the motor and put it on a Cadillac Fleetwood bike I have sitting in a shed. I bought that bike years ago to go riding along with my wife when she was able to ride her Schwinn beach cruiser. It has the first version of the Nuvinci CVT hub (N171). Unfortunately the hub bearings have become loose and adjustment isn't possible, the wheel has lateral movement on the hub. I liked the Nuvinci riding experience so years ago I had also laced a N360 into the wheel of my wife's Schwinn beach cruiser and since that bike isn't used anymore I'm going to put that wheel into the Cadillac using a roller brake because unfortunately the N360 didn't come with a disc brake interface. The Cadillac is a sweet riding bike, heavy mostly because the N171 is a heavy hub. I live on a mountain so it is no small task riding up with a non-assist bike, a Tongsheng mid drive might be just the thing to get the Cadillac back into riding rotation.
