my bike is being triked, its been stripped completely and ready to be put back together but need a swinging arm for a chain driven bike, any suggestions plzzzzz??
Just be careful, as a bike swinging arm is subjected to relatively little in the way of lateral forces, when compared to that of a trike ridden hard. Watch Soap Box Challenge and see those forces in action with creations fitted with tall bicycle wheels. They don't last long. You might want to speak to Mark at Grinnall Trikes near Stourport (01299 822862) as he might offer some advice, although he is a very busy chap. His trikes are works of art IMHO and beautifully engineered. Good luck with your project.
