My son is looking into bringing them into the country, I think you have to buy a full container of them. He also got a beautiful road bike that is made to look good and last. He says there are many of these things all over the place they use them for everything. There are larger ones and I think that I would get them instead of the smaller one. He brought this one as carry on. I was looking at it and if you cut the girls bar out and turned it over you could get the china engine in there. It is only one wheel drive, there is no diff. But it would be easy to attach the sprocket to the drum. I have never seen spokes that heavy, my old BSA had smaller spokes, the bearings are the same way they are huge. I love the rod pull brakes and the old time levers, I will get some better pic's of them. All the sides of the bed are very thin sheet steel, I think it would turn into a speaker with an engine running, I think it would look much nicer with some Mahogany sides varnished. Ill keep you posted. Have fun, Dave
