That type of 4-stroke engine is far too heavy to be attached to a bicycle frame, and we haven't got to discussing the anemic stopping performance of rim brakes.
no trafic
no speed
rambomert - my first post was in jest, but I want kidding when I said good luck. It's just not safe to strap that huge engine onto a bicycle. The power, weight & lack of added stopping power make it a literal death trap. It doesn't matter where you ride it or what's around you, the frame is more likely than not going to fail, or worse.

I have lived in South America for many years and I guarantee you that it's much more dangerous down here.

Stretch it!
You can mount that engine on the bike frame, cut and stretch it about 12" (about 300-330mm). when you weld a bottom piece on, make it rectangular steel. or make mounts that will bolt on to the frame. This has been done many times (check out the forums on www.motorbicycling.com, and you'll see how Crazy Horse has done it over and over again, using a similar engine, and stretch cruiser frames, as well as small OCC choppers from Schwinn.
If the engine is too powerful, don't use full power! but that power comes in handy on the large hills in most of the pacific islands. I live in Puerto Rico, and we have very steep hills as well. I didn't catch how big that engine is, but if it's a 49cc, good to go! Personally, I would not put anything more powerful than a 70cc engine of this type, on a bicycle frame. I'd also weld in pieces of triangle cut steel, to re-enforce the joints.
