I will try to contribute something, as soon as I can. Oh no, another project bike :)
Thanks

My own bike is in bits in the garage :o Then on the other hand the weather has been so awful the local ducks have got up a petition :rolleyes:
I'll look forward to reading more about your project porschetoyz :)

I don't have a gas powered bike anymore but I bought an engine awhile ago out of boredom. I put it on a mountain bike and then on a LWB recumbent. I will toss some pictures up after work.

Someone pointed out there is a better forum/source of information about gas assist bikes on the net. Where/what is it?

Check out Alcohol Can Be A Gas by David Blume. There is a nice section in there about small engines that I hope to be getting the best of here before too long. We are looking at raising the compression on small 4 strokes enough to burn the fuel correctly and introducing HHO to the mix also with a small generator run off an alternator. Gotta be ready for anything anymore.

Try these perhaps?

Interesting idea. Is it going to be multifuel capable, or just alcohol?

I own all kinds of these kits. I have built a few for people, that use them for commuting.
This has been the best out there, in my experience. I am 220. if you weigh more there is a bigger engine there http://www.staton-inc.com/Details.asp?ProductID=3316
200 miles per gallon cant be beat!
of course the only drawback is that is doesnt work when its raining. for that I would go with a chain drive.

Due to the higher compression if gas is used it must be of the highest octane available or lesser with an additive booster. The idea is towards self sufficiency with this though and our efforts will be grass root (i just can't stop with the innuendo's tonight) to start of course but perhaps as time goes on the idea will spread? A small legal operation to manufacture ethanol at a rate of 4-5 gallons an hour is not that much of an investment actually. The ethanol will not be made using corn either to quell that argument in the bud. There are many forms of biomass that can be used that are far superior to corn that don't take anything away from food producing agricultural land. One of my favorites is spent wort from beer production! And of course grass clippings as alluded to earlier. In fact according to Blume corn is perhaps one of the worst options available.
And thanks for moving this to the correct spot. After reading that poll thread I for sure was worried about panties bunching but it seems like the higher powers here at least have level heads.

Can you attatch one of these onto your mountain bike and still be able to ride on singletrack? When you do add this engine to your bike, does it lose its status as an unpowered vehicle?

There are some that would say yes, http://www.youtube.com/watch?v=n0eZynCSNyU

But I for one am not there with the concept. For one thing you had better make sure that land use regulations allow it. The bikes pictured would not meet legal criteria for street use either as the engines are too many cc's.
I guess I always considered bicycles to be powered vehicles to begin with? Putting a small engine of any sort, gas or electric, does change the vibe for sure. You just have to come to grips with what your needs are and for me hauling heavy loads that would normally have to go via auto by bike is a priority. The use of motor assist makes that mission safer and more pleasurable.

Did some mods to the bicycle utility motorassist vehicle today. Basically swapped out a cheap 26" sus fork front end for a cheap 700c rigid. The front end is much less vague with no loss of comfort. Used a NOS Girvin Flex Stem that I had in stock which I am not sure does much but it looks cool! Surprisingly I had a couple of other choices of 1 1/8" quill stems to choose from also that I had forgotten about in this age of threadless.

This bike is so super that I thought this old Speedwell head badge was appropriate so I stuck it on also.

Took a few errand runs today and one was to get a steerer tube cut and starfangled nut installed for my town bike at the bike shop cause I don't have the proper tools to do so. It was $4 well spent and got to rip around some and show off the bumvee at the bike shop. The manager took it for a short beat and came back with a big grin on his face and the wheels turning in his head....The flatbed makes it easy to transport stuff, just need a few bungies.

The little rack pack stays there nicely after threading the attachment straps around one of the bed boards. Makes a handy place to keep the lock and tool kit/flat stuff. This bike will carry a pretty good load without any effort on its part or the operators:lol:
