I would pick the 4 stroke as they are better cause of the TLC you have to put into them and they are easier to fuel up, no mixing. Where would you get a 4 stroke for that cheap?

I like the 2-strokes much better...
I think they look a lot "cooler" that the 4s.
The 4 that I rode felt good once it got up to speed, but it didn't have as much torque as the 2s.
It also had a centrifugal clutch... (I like a real clutch!) & I didn't like that the 4 didn't have engine braking.
All in all... I think that bikes with 2-strokes in them, look & ride more like real motorcycles!
I also think most of the 4s look kinda like Peewee Herman bikes...

Seeing I have both I chose the 4 stroke because that is my major ride. The 2 stroke is fun as all anything and is rock and roll with amazing power but when it speaks to me it says "drop your throttle down just a little or you're gonna need a rebuild."
When I ride my 4 stroke it's just smooth EVERYTHING from initial delivery to cruising to climbing hills. When my 4 stroke speaks to me it says "Pardon me. Do you have any Grey Pupon?"

Different motors for different riders. What kind of rider you are reflects on what you are riding.

I'm equally adept with both systems. But for motorizing bicycles, I think I'd stick with the 2 stroke due to their simplicity, power, and ability to use an expansion chamber for a bolt on power boost. When well maintained you can get respectable life out of one and that by using good oil. (BIA TCW rated or good synthetic after the breakin interval)

As light as a bicycle is the power of a 2 stroke can make it feel like a rocket especially when you get into the power band of the motor where it comes alive.
Wheeeeeeee !!!!

I like the light weight and power of the 2 cycle. I don't mind mixing and I carry a bit of oil so I can just pull up to the pump and fill up with everyone else if I run out.
