I have a five horse briggs motor on my bike and a aluminum wheel set with a shimano cbe110 rear hub. My question is can I weld a flange on to the hub?

Not unless you're a real talented welder. The chances are you'll destroy the hub.

Why would you want to weld anything to the hub? Are you mounting a sprocket or pully to it? There are other and better ways.

I am mounting a sprocket.
I'd explore some of the sprocket adapters available. You should be able to get almost any size sprocket to work with one. I know they aren't cheap but they do work well.

Of course you can always use the 'rag-joint method. Installed correctly they work just fine. I'd just hate to see you take a chance on damaging your hub by welding on it.

"Rag Joint". This is the 2 stroke kit supplied method of attaching the rear, driven sprocket to the rear wheel/spokes. It consists of a sandwich of sprocket, rubber, spokes, rubber, metal plates and the nine fasteners that hold it all together.

The term is also used to describe a type of coupling often seen on the steering shaft in some automotive applications. In fact those were called 'rag joints' long before the Chinese engine kits were made.

Thanks. I've heard of the "rag" joint in the automotive world. Puzzled me on a MB. I've never had a China kit. I'm goin with moped hubs, 21" dirt bike wheels, and a 212cc.


As for mounting sprocket look into treatland, rear 36 spoke hubs, complete around $50. Hard to beat!
