Hi all- This is my first post so let me explain a few things about myself first, and then some questions. First, I am an American Expat living in Beijing China. Driving here is a complete hassle, so like a lot of the country I ride a bicycle to work, a Flying Pigeon, in fact. The rub is, when I lived in the US, I was an avid motorcyclist, which I miss tremendously. Now it would be easy enough to buy a motorcycle here, but it would also require a license, which is a bit of a pain. So the thought of motorizing my Pigeon seems apt. Now there are about a million bikes rolling around china with 2 stoke engines strapped to the frame or Velosolex copies strapped to the front wheel, but if I am going to do this I want something different. So here are my project requirements, which I am hoping I could get your suggestions on.: 1. Bike is a 28" Flying Pigeon Double bar frame. (picture attached). I will construct the bike to look like a pioneer motorcycle. (1900s) 2. Engine must be a four stroke, and look suitably vintage. Two possible exception would be if I could source a Monarch boxer twin or a Villiers bike engine kit. 3. All parts must be made in the PRC, Taiwan, Hong Kong or Macau. (Monarch or Villers excepted of course) 4. Now an NE5 whizzer engine fits the bill, being made in Taiwan, however, I haven't been able to find a source for JUST the engine kit, let alone one here in the PRC. (any suggestions?) 5. Is it possible to use a rear 3 speed hub with internal transmission to increase the efficiency/speed of the bike? Sturmey-Archer hubs are now made in Taiwan, so they also fit the bill....if they are useable. 6. Are there any add on transmissions for the Whizzer engine? Perhaps something that fits behind the seat post pillar? Thoughts? Suggestions? Your help is appreciated.
