Are there any benefits from gearing a motor bike kit?

Oh believe me I would love to have the capability and I think it's pretty cool, I just don't want to drive around NYC on an already illegal bike daring cops to pull me over with my trailer. I'll get the HD shift kit if I decide to keep my current build, I'm considering selling it and building something more powerful and replacing this junk Chinese engine with a higher quality Chinese engine lol. If I do use something more powerful I'll have to make my own custom shift kit as there is a pretty radical difference with all the engines I'm looking at so the sbp shift kits probably won't work.

There's nothing inherently wrong with the Chinese engine so long as you keep the revs down to a sensible level.

Another aspect of motorized bicycle touring is the notion that the bicycle should travel at speeds approximating that of a fit cyclist, not at speeds of a proper motorbike.
Part of the attraction of motor bicycle touring is seeing the world at a more gentle pace; actually able to appreciate the sights with greater detail than being on a full blown motorbike. I've owned both types of transport, and can say that the slower speeds of a bicycle are much more enjoyable than ripping along at a banshee pace.

The laws in Australia (especially the lower south eastern states) are equally draconian for the motorized bicycle enthusiast. Every day (when riding my bike) i know that i'm risking $3,000 in fines, plus the potential impound, as well as demerit point on my car licence etc.
I don't give a damn - i'll take things as they come, but my experience has shown that if you ride sensibly, a good deal of the heat is removed from your travels on a motorized bicycle.




Here are a few examples of my travels:

I have no plans to do high speeds on a bike frame/wheels they really aren't made for speeds of more than 30 and would probably fall apart at sustained speeds of 50 or 60, besides doing more than 30 on the streets of an urban area will get me killed since there's just too much traffic. I want a different engine because a 4 stroke won't attract as much attention as a two stroke and I figured I might as well go for something bigger with better construction/tolerances while I'm at it.

I can see your point, though in practice the 2-stroke engine can be silenced quite effectively. Also in practice a 4-stroke engine looks monstrous in the frame compared to a 2-stroke. This is the main reason why i didn't go 4-stroke because it visually attracts more attention on the eye.

From behind the bike, you can't even tell that a 2-stroke engine is bolted in the frame, unless you have a tuned expansion chamber attached to the exhaust port, which is the main reason why i don't have an expansion chamber fitted to my bike.

True, the 2 strokes are very compact and aren't as noticeable as 4 strokes and I guess I could try silencing it. Any tips on how to quite it down?

The exhaust can be noticeably silenced by fitting 2 1/2 feet of 1/2 internal diameter chemical and heat resistant silicone hose; attached to the muffler exhaust outlet and the intake noise can be reduced by fitting a Rock Solid Engines reed valve intake, of which both are fitted to this version of my bike.
