Hi...!
I am wanting to do a project for the science fair, and i want it to involve motorbicycling.
My first plan was gas or eletric? witch is better?. I also thought about doing eltrico-magnet thing
(as listed in a prevouis thread: The never attemted..(plz look))
If you had any ideas i'd like to hear them

(another thing is that i usally pay for the stuff on my iwn, but for the science fair my mom will provide the $$$$

Lucky ME)

Converting your motor bike to run on ethanol might be a science project.
I think it would only require a larger main jet in your carburator. (Do a search on
alcohol or ethanol and see what other members have done)
Home depot sells a veggie based 2 stroke motor oil.
Your bike would be "Fossil Free".

Some current formula 1 race cars use a KERS system; converting braking energy to stored power for later acceleration. Some generate current to charge a battery. Others spin a flywheel with braking power. The flywheel system might not be too hard to add to a bicycle, utilizing a friction roller to transfer the power.

When I received my motor kit, I asked my teenage sons if they wanted to use it in a science project but they were not interested.

I remember in my fifth grade science fair what I did was I took apart an old 4 stroke Briggs&Stratton off a pressure washer and brought that in. Think I used a poster to show the four strokes, what each one did, and how the internals of the engine worked. My brother helped me out with it, but everyone at the fair thought it was so cool, and I learned how an engine worked.

When I was building my motor-bike, I did a web page comparing the cost of operating a gas-engine (4-stroke) bike compared to an electric. The gas-engine was considerably cheaper both to purchase initially, and per-mile of operation. The Bionx page has figured for their electric setups and you can figure out what gas engines cost.

{-this didn't surprise me too much because if electrics were really cheaper per-mile, then commercial trucks would be electric instead of fuel-burning, and none of them are-}

Lots of people love to claim that electrics "don't pollute as much" but there's simply no proof of that. It is true that batteries can be recycled, but there's inefficiencies involved-both ecological and financial.

The only definite claim the electric bike motor setup could rightfully lay claim to was lower/easier maintenance.

Well, you could say that an electric bike is better for reducing air pollution. Global warming is a big "hot button" these days.
