    Bike structure

    I am extremely new to fabrication and was wondering how i can calculate how much weight a fabricated bicycle frame can hold. As i am currently doing a 2 stroke conversion on an old pedal bike and need to make a new peice for the frame sturdy enough to hold me and the engine.

    You will need to either model the frame in an analysis program or do the statics and dynamics load vs stress and strain calculation by hand.

    Here is an online 2D- Statics Analysis program.
