What would your dream build consist of?

Guy hits 65mph with a 146cc engine on this motoped, and you can tell it's not maxed out yet listening to the rpms.

Then there's always this:

Now that looks like fun!

Most motopeds are running 49-125cc 4 stroke dirtbike engines so no need for an expansion chamber. Theres a guy in my town with the motoped survival black ops with a 140cc piranha 4 stroke engine and says he can do 75mph.

Very interesting.

maybe, i am wrong but i think there are many legal hurdles with motopeds being street legal. even more than motorized bicycles. i guess it depends by state. crazydan yeh i saw that 146cc video many times. it looks so fun but also dangerous

A 49cc lifan single speed would keep it legal, just keep a 140cc 4 speed lying around for occasional offroad fun.

Although thinking about it, only reason motorized bicycles remain classified as bicycles is because it started life as one and wasn't manufactured as a motorized vehicle. The motoped frames (and possibly built-in tank frames) were designed with a motor in mind, which would probably legally put them in the moped category.

I think it's the same as motorizing a shopping cart, if you look like you'll get killed you'll probably get pulled over, slow carts are OK though, and motorized cases of beer are apparently semi-acceptable in Germany. That's life I guess.

But it really depends on if your local DMV will even register it. I know here in Texas the DMV will not register a bicycle as it does not have a VIN.

In the end I agree that this is the reason why many of us are doing this vs mopeds and others is because these operate in a gray area of the law where they are street legal without licensing and paperwork.

But then again, this is a dream build thread, and in my dream i can legally put a jet engine on my bicycle.
