That is not going to be an easy fit, anything can be done, it is just how much mechanical skill and ability do you have amd how much trouble and expense do you want to go through trying to fit the glass slipper on until you find the beautiful Cinderella ???...lol...lol.

These engines are designed to fit full size beach cruisers for best fit with a minimal of fuss and bother like the Hyper Beach Cruiser steel frames...Myself as well as a few others here on the forum use Hypers.

You probably do not have Walmart in Lithuania but at least this will show you what your looking for.
Whatever you do, do NOT use an aluminum frame bike as they usually crack and brake when a motor is put on them, make sure your getting a steel frame to build upon.

A 30 inch seat post tube??? Are you around 7 foot tall? Did you measure the seat post tube from the top of the seat post tube to the center of the bottom bracket? This measurement doesn't include the seat post.

If this is measured in centimeters then that is a very small frame bicycle. You need a minimum of a 46 cm seat post tube.

Seat tube 30 cm >> 11¹³/¹⁶ inches
Top tube 47 cm >> 18½ inches
Bottom tube 56 cm >> 22 inches

I'm also 95 percent sure that the frame he is looking at is aluminum and not steel...I would not even attempt to build a motorised bike from this particular bike...Too many problems to overcome and it will probably still not ever be right.

It certainly looks like it's aluminum.

I agree with Jerry on this one. That seat tube is going to be too small. On a standard Triangle road bike/mountain bike frame a 47cm/18 inch seat tube height is generally the bare minimum to fit a 2 stroke or small 4 stroke engine in a frame without any fitment issues.

Small cruiser frames are an exception, such as the Schwinn Stingray, since the lower tube comes out more parallel to the ground and arches around and up, creating a more round opening in the frame for an engine to fit.

What was that someone was saying about expat British...

@decemberblew I concur with everyone else, that frame looks to small. It's gonna be quite a pain to fit, if you can fit it at all. I hope you can find a better bike!

Someone has to teach you peasants of the unwashed masses how to read, write, spell, and pronounce the PROPER Bostonian Brahmin style of the English language...lol...lol.

The slovenly so-called English being used in this country today is absolutely appalling and disgusting...lol...lol...lol.

Let me guess, the centre of your tyres are the wrong colour too.
