Cyclist encounters many problems when they ride bicycles. People usually can't afford a car and usually carry multiple items on their bikes but don’t have that much space. Additionally, Aluminum frames do wear out because of accumulative fatigue which reduces the stiffness and tensile strength of the material over time. It's believed that aluminum frames can pass through a limited number of stress cycles before developing cracks and eventually failing.
Crack!! POP! The sound of your bike breaking down both the tire is flat, and the frame is broken. Too much overuse and barely avoiding obstacles while going very fast.
As a result, if the bike frames are left unchanged then many cyclists will waste their money on something that can’t be fixed. Although it looks very durable, I believe that there can be many ways of shifting frames into a different position.
