    Is cutting a bike frame a really bad idea?

    Im thinking of cutting the top tube out of a BMX frame and mounting an engine onto the seat and bottom tube, then welding a dual rail around the cylinder head in place of the top tube.

    Done right, no reason you can't do it. They cut and weld car frames, why not bikes?

    yes -- well here is my old same story again

    I can weld a little --

    but -- for a weld such as needed in this case

    I would take my frame to my friend -- he's an EXPERT WELDER

    wouldn't want that thing to break (fall apart) at speed

    woww that hurt's -- should have worn my METAL CUP (protector) !!!

    after that collapse (pinch to the special zone)

    it would make it hard at nights with the little Lady to

    Ride That Thing Mountainman

    I noticed your catch phrase a long time ago! Just have to say you made me laugh hard with using it this time!

    Respect...

    No reason why anything can't be done,as long as it's done properly.

    like everyone is saying, if welded properly it should be ok. It isnt going to be as strong as before but it will hold.

    What kind of material are you using? most (decent)bike frames are heat treated, and cutting and welding require the frame to be heat treated again.

    yes -- well noted Steve

    and this will be the OFFICIAL THIRD WARNING TO MOUNTAINMAN

    CONCERNING -- GETTING MIXED UP REGARDING TO

    WHAT THE HECK HE IS RIDING !!!!

    remember to know what you are riding when you ride that thing -- MM
