    Well, we might be looking at a misunderstanding here.

    When you hear folks talking about a 20 inch bike, a 24 inch bike, a 26 inch bike, etc., they're referring to the size of the wheels. I've never heard of an 18 inch bike in that sense. And such a thing would be a child's bike.

    So I'm wondering if your 18 inch Peugeot is actually 18 inches from the bottom bracket to the top tube. Or to the seatpost.

    If that's the case, then you should be able to fit an engine in there.

    Photos of your bike would help.

    To me 18" bike means the size of the frame as measured by the length of the center tube.

    and 18" is usually a fairly large frame.

    actually...i have a vintage 18" tyre and rim here. and a 22" :) 28" was pretty common once, too. its come back into vogue, apparently.

    on my 20" frame....i have approx 4 inches between plug and top tube, 5 from cylinder head to top tube.
