I am personally a 2-stroke fan because that gives you the best bang for your buck. The lighter the vehicle, the more you pedal and the less gas you use.
I use my bike as a pedal cycle more than 50% of the time because it is good healthy exercise and it is suitable for me to do so.
HTs are dirty and the EPA does not like them. However, in terms of burnt fuel, 2-stroke MBs give you a very low carbon footprint.
Of course, if you use the 2-stroke as a fully powered bike, it is no better than a 4 stroke. But the 4-stroke, being heavier, is not conducive to use pedal-only use. Furthermore, the 4-strokes with engines mounted in the middle of the bike are not conducive to pedaling because the engine width is wider than the 2-strokes.
All that is by the by. Really, I started the thread to attract any pictures of bikes by environmental enthusiasts and I'd like to hear how they perform.

some of your points are hard to understand HybriPed
do not think that statement to be true
my 4-stroke is pretty darn light -- I think anyway
I use my bicycle very often without motor -- it rides very nice
and with a friction drive -- not dragging any extra chain
I guess that you are just not much of a 4-stroke kind of guy
at least over here
the 2-strokes seem to be on the way out
unless they comply to strick regs ??
ride that MB thing

so you are saying that co2 is more toxic than the rest of the rest of the by products produced by burnt 2-stroke exhaust???
And I think my r/s eho35 weighs less than my ht 2 -stroke.

You got a pic to show, vtec?

Ht weighed almost twice as much as the eho35... my townie is all aluminum and weighs maybe 20-25 lbs. I pedal it very easily. Eho35 gets between 200 and 220 mpg.... and the emissions are regulated to CARB standards.
both engines are brand new... never used.

stinkie little THINGS
proven
less in not only weight but much lighter in what it throws out in the world
I guess that if we are trying to sell our message
to someone who does not know better
I could tell them that my little 2-stroke was saving the world as we know it
but those of us that have been around the block
a couple of times regarding engins
or even followed behind one
know
those little 2-strokes are stinkie little THINGS
as we ride those THINGS

Pretty impressive comparison. Thanks for that.
Hmmm
The 2-stroke is simpler and should be 1.5 kW (2 HP)
If there is 2 HP 4-stroke out there that fits into the main frame triangle (for balance) and is narrow enough so that the pedal cranks do not have to be modified (so they don't scrape on tight corners), then I'd have it in a flash.
Any suggestions?
