    Look at this.....

    As far as length, I buy a 1 meter stick of Grade 5 all thread. Any fastener store has or can get it for you, for 6mm it cost less then $3.00. In what you are explaining I'd go with the mount below, as you don't want to install a stud or bolt and try to pry it can break the engine or pull the threads while trying to do it or while you ride it. If you decide to use all thread, heat and bend it to fit.... OFF the engine. I have experience drilling holes in a frame....won't do it again...split tube in two...I posted pictures.

    They are made in many sizes....

    This clamp can be bought or made. One of the vendors sells them, can't remember which one tho...maybe one will jump in....
    Here you go....

    I used . . .

    a whomping big C-clamp to gently, but inexorably, squeeze the downtube a little bit where the studs cross the frame. Cut some pads from EPDM roofing or inner tubes and cushion the mount. Once it is painted up and the motor is mounted, it isn't even noticable.

    Just go slow and make sure you have the jaws of the clamp perpendicular to your frame.

    your frame looks ruined. It could easily break in 1/2 now that you have filed it down

    Hi dylanpieper

    Please, throw your frame away. You mentioned that cutting into your frame was required.

    I've put up a post on a saftey related issue with large tube thin walled aluminium frames.
    Basically, don't cut into or deform any aluminium frame - if you have to do this, find another bike frame that will work or find another mounting solution.

    Riding the bike with a motorised kit installed on a damaged frame is complete stupidity

    The end results can look like this, and far worse in one case i am aware of.

    This gentleman suffered injuries from not wearing a helmet but if your frame breaks and it quite possibly will, your injuries will be many times worse if not wearing a full face motorbike helmet.

    Please dylanpieper do not even continue with assembling or intending to ride your bike with a damaged frame.
    Start again with a new undamaged frame - I can't make you do anything but if i could, your frame would be going straight in the rubbish bin; to protect you from injury and pain that may be waiting as a ticking clock, by means of frame failure.

    Forgive me for saying that dylanpieper but i am seriously concerned for your saftey.
    These motorised bicycle kits are not toys and should not be treated as toys.
    Because you're wearing so little protective clothing and gear riding a pushbike, the injuries from a preventable accident can be quite horrific.

    They are lovely pieces of equipment when treated with the care and respect and intelligent operation they deserve.

    Can you give us a better quality photo of the hole and cracked steel frame.
    Maybe use the macro setting on your camera and take the photo in strong sunlight.

    I will try and get a photo of my next door neighbours cracked aluminium frame as he tried to secure the Chinese engine kit - it's a good example of what not to do and the potential for serious injury as the frame would very well have a stress failure in service.

    If i had things my way, i would like to see some kind of legislation requiring sellers of motorised engine kits to have their potential customers sit a test/exam requiring them to answer a series of questions, to determin if they have the correct level of competency to safely install the engine conversion, then have the bicycle presented to the retail outlet to verify if it has actually been safely installed.

    Like all things where there is a potential for injury and the government with a pure love of "banning" something because there's political mileage or profit involved in forcing people to use accepted methods of transportation, it will only be a matter of time before some people (through their ineptitude or incompetence) wreck the system that allows us to have the freedom to ride motorised bicycles, .
