Bicycle Frames are made from a number of metals and carbon composites. some materials as follows: 1. Steel Frame Bicycles Strong, Stiff and comfortable, Alluminium Frames Light, Stiff and comfortable, Titaninium Bike Frames strong very light and comfortable, carbon framesets ultra light, stiff and comfortable.he cheapest metal used is would be a high tensile carbon steel. Better steel bicycles are made of chromoly steel, which is an alloy of steel with chromium and molybdenum. This alloy makes the steel stronger and harder than cheaper steels. Steel frames can also have butted tubes.
