    Hi there. I used a Madwagon beach cruiser with a Grubee (happy time type) kit.

    Here is how I mounted mine. (It came with the 3 hole bracket which is the shiny plate showing under the muffler side of the motor). I used the stud bolts that came with the motor, which were in the frame clamp there. Instead of using the clamp (of course), I measured and hacksawed them to a shorter size, filing the ends a little to prevent crossthreading, then used a 6mm nut that was in the kit (bunches of the little nuts that take a 10mm wrench) to make sure the threads were right. I used a 5/16 fine thread high grade hardware store bolt and nut with a bunch of washers, to bolt it up. The regular clamp is on the seat tube of the frame.

    There is an alternative method that I highly recommend now that I know of it:
    mount the frame to a junction box cover plate (or any iron/steel plate you want, about 3x3 or 4x4) and bolt THAT to the frame using u-bolts and rubber shims for vibration resistance.

    If the vendor won't answer the phone, on several occassions on different days, give them a low review on
    Most of the vendors (like sickbikeparts etc) have all kinds of replacement parts and upgrades (motor internals, plugs, gaskets, fuel petcocks, magnetos etc).

    Probably best to buy the wear/service items like plugs and gaskets, and buy an extra whole motor kit.
    you can swap to your bike if necessary and hunt for parts later, or build another gas bike if SHTF. It will be priceless then.

    I think the EPA just said FU to the china mfgrs, and banned the 48cc size due to a technicality. I think the 66 will still be coming, but it sucks if you need a 48cc to be legal.
