Alt Bike Culture - 33cc Chain Saw Powered Folding Raleigh

Hi I am trying to convert a folding Raleigh compact, to 2 stroke chain saw power!, the Mc Culloch engine sits neatly on the pannier rack and I have made brackets so I can bolt it down, the centrifugal clutch bell housing will work well as the transfer of power but I need a method of attaching a small bicycle sprocket to the existing clutch bell housing has anyone got any Ideas?
Notice I didn't say suggestions!!
Because I'm sure the purists amongst you will say don't be a lazy beggar and why petrol power??

Regards Stuart living in Spain and Loving it!

No idea, and why use petrol power and all that.

But one thing you might look at is the size of sprocket you'll need. In particular, some of the motorized set-ups used a giant rear sprocket to get the speed of the motor matched to the speed of the wheel. You might check into that, or you may wind up being geared 8 times too high.

I suppose its the weight factor and the lack of range on batteries plus the charging time, with petrol the power to weight ratio is better especially with small 2 strokes and the top up is easy and quick, I have a lrage cog lined up for the back wheel and am thinking of one of those pit bike sprockets for the motor so I may not be geared too high, or I may get up to 50mph you never know!!
Stuart

You might try googling "chainsaw engines on bicycles". I have in the past found tons of information on the subject there.
I haven't done this but here are some things I found out when researching it.
1.Chainsaw engines are high rpm some running well above 10,000 rpm so you'll probably need at least a two stage gear down.
2. Chainsaw clutches typically lock up from 1300 to 2300 rpm and they must lock up to stay cool. If they don't lock up they will destroy themselves pretty quick.
Try instructables.com also. Someone has done this I'm sure.
Good luck and have fun. Just building it will be fun and If it works even more fun.:)

Weld it.

But really, don't be a lazy beggar and why petrol power??

Seriously... weld it. If the weld breaks get a smaller motor.

But, doesn't the clutch system already drive the cutting chain of the saw? If that is the same 1/2" spacing, then maybe it can fit bike chain.

Hi Jensen

Yes it does have a sprocket already fixed to the clutch bell housing but it is a solid cog the teeth drop in from the chainsaw blade which is different from a bicycle chain, its too wide to fit into a cycle chain slot

Best regards Stuart

If you look around, especially over in Single Speed and Fixed Gear, you'll find reference to some rear cogs that have a 6-hole mounting pattern that matches up with disk brake specs. Attaching it to an existing thing should be easier than trying to deal with something that threads onto a hub like a usual fixed gear cog.

2 stroke engines pollute more than cars, are inefficient and noisy as hell and totally defeat the purpose of a bike.
i hope i never encounter you on any road on this earth, and you would be better off just buying a car, or at least a 4 stroke scooter.

Hi Chiapas

I always thought the idea of a bike was to get from A to B faster than walking, so what is wrong with some power assistance? I suppose you are against air travel as well!

As for battery assisted bikes you don't even want to know what making batteries does to the environment.

Anyway Cows polute the atmosphere more than 2 strokes, may bee I could run an engine on methane!!

Regards Stuart

What an awesome idea. Must be obnoxiously loud though.

as i said, buy a scooter if your purpose is to get from a to b.
I agree it is a good idea to stop eating beef too, and deff. avoid air travel unless absolutely essential.

2 stroke engines pollute more than cars, are inefficient and noisy as hell and totally defeat chiapasfixed's purpose of a bike.

give this a shot. cant hurt. i used to do this. then i found out i like just pedaling better. and it's quieter, and cheaper to pedal. but hey, its your world, not mine http://www.motoredbikes.com/index.php

Hi Chiapa

So I can't use a chain saw, I can't fly, i can't drive a car, or a 2 stroke scooter, I Have to become a vegetarian and live of vitamin substitutes to stop the planet dieing from metyhane gas, Can I still breath in your world Chiapa is that allowed?

Have you thought about changing the gear on the clutch to a wheel? Driving the rear wheel directly will make life much easier.No chains or belts to mess with and you only have to change the wheel size on the engine to correct any ratio problems.If you have a problem with it,you just lift it up and ride home.You can still mount it to your rack.

What a great idea!! no chains gear ratio with a small drive wheel will probable be just right!! what a clever person you are thank you!! Stuart

Pedalling is all very well and good till you get arthritis in your knees!

Now you know why i need power assistance!

Or is Chiapa going to deny me being able to get about?

May be he thinks all non cyclists should be in a home or something!!

Or better still put down because they can't cycle anymore!!

33cc. That's it? Time to man up and atleast get a 80cc chainsaw. I saw someone stick a 750cc motorcycle motor into a Vespa.

Being I use to work at a machine shop I have found the best way to try out stuff like that without a Masters in Mechanical Engineering is to just weld it and try it. If it fails cut it and weld it again.

Or check the advertisements...

And this message brought to you by means of many computers all running on electricity that was made by

burning coal!!! :rolleyes:

here at CDU, our servers are run by wind and solar power actually...
I hold firm to my opposition to two stroke engines, I believe they should be banned (they actually are banned in several US statessuch as California and some European cities such as Paris).
If Windeco has arthritis and needs assistance, why not look into the highly efficient electric-assist bikes out there? If what you want is to build something yourself, there are kits to retrofit your bike too. This is the best in my opinion: http://www.greenspeed.us/bionx_motor_bike_kit.htm
You would be doing the world, your community and yourself a favor.

California is just a messed up state and shouldn't be referenced for anything. Sorry, but any state that allows naked yoga but no guns to defend yourself with needs to be kicked in the crotch.

By the way your windmills/bird killers are probably maintained by men who use diesel trucks. The factories that built your windmills are most likely coal or patroleum powered. They were transported there via diesel trucks. The material that makes up the windmill had to be mined or produced which often leaves a lot of wasteful byproducts. I'm sure the list just goes on and on and on and on and on and on and on and on...

Also your phone lines are maintained 5-6days a week for 8hour days with the trucks running 7hours of that day to operate the boom by these trucks...

Fixing your guilt does not fix the enviroment. I'm also guessing that a 33cc chainsaw driven bicycle will help the enviroment 10x better than buying a Toyota Prius which destroys the land from where their battery is produced so bad that NASA uses it to test their Mars rovers.

I suggest a belt drive like Trek is doing with their commuter line. Screw the chain-driven sprockets.
good Luck.

Here in BCN province AVC we have all our electricity provided by a 1 megawatt solar farm our back up comes from 30 Windmills that kill birds of all sorts on a regular basis, the only Bulls we have around here are bred for bull fighting, all the pigs chickens and rabbits in the region are bred in factory farms, our beef comes from Argentina so has travelled 1000s of miles to get here, even the vegetables come from Africa Venezuela and timbuctoo for all I know but we eat from our own veg plot have our own chickens and are thinking of breeding pigs Our heating is powered from Olive Carob and almond prunings which renew themselves every year incidentally pruned by chain saw 2 stroke of course I suppose you would have me prune 200 trees with a bow saw? our water heating is from solar power our well pump is solar driven so in short I don't think we can do much more to help the environment so I will convert my folding bicycle to 2 stroke power as I have earn't my eco credentials so stick that in your pipe and smoke it, ohhhh sorry I forgot you don't smoke either, and probably don't drink except water of course:)

Thanks smittie
I'm glad someone out there in bike land has a grip on what services are provided and how they use vehicles to maintain stuff and what cost to the environment !!

I suppose chiapa lives in another universe where electricity grows on trees.

He is in the wrong State he should move to where all those Amish live in Iowa get himself a horse and buggy and make a barn using only hand tools and do some butter churning and roof shingling

Anyway as you say California is not a good State to use as an example, look who they elected to be governor!! I rest my case

Asta La Vista Baby

He is in the wrong State he should move to where all those Amish live in Iowa get himself a horse and buggy and make a barn using only hand tools and do some butter churning and roof shingling


I have family from northern Missouri and the Iowa area. The Amish and Menonites in the winter time heat their stables with a gas powered generator. But they just put it on some sort of wooden wagon for some reason. Something about how they don't want modern machine touching God's Earth.

I remember years ago before AT&T took over Bellsouth hearing that Bellsouth had more vehicles than the US Military. Bellsouth just serviced the southeast United States too. Also to maintain those lines on top of AT&T their subcontractors use F450+ trucks hauling excavators and backhoes that run off of (you guessed it) diesel and get roughly 5-6mpg. Plus that big truck in that picture has a F150 follow it all day along with what we call a "baby bucket" which is a Chevy 3500 diesel bucket truck.

Green jobs are nothing but a joke and a power grab by the government. If the government signs your checks and is what keeps you eating everyday. You aren't going to stand against them.

Let us know how the chainsaw conversion goes.

California is just a messed up state and shouldn't be referenced for anything. Sorry, but any state that allows naked yoga but no guns to defend yourself with needs to be kicked in the crotch.


Yes, because allowing something that is done in private that isn't harmful to anyone is a horrible thing to do and banning guns that are manufactured specifically to kill humans en masse as effectively as possible is such a more horrible thing. Frankly though I don't believe that any state is backwards enough to ban naked yoga, or stupid enough to even waste their time in any regards to it.
Honestly now let's get past it and keep talking about bikes.

Actually I meant to refer to naked yoga in public. San Francisco specifically (link: http://www.abc.net.au/news/newsitems/200409/s1205883.htm). I don't care if someone drinks gasoline and smokes cigarettes while riding a unicycle and jugling chainsaws. And honestly I don't care if someone does naked yoga in public. I just find it ironic that they'll allow some 80year old get naked and put his legs behind his head on a street corner but god/allah/darwin/whomever forbid you defend your home from a criminal

And guns are not design specifically to kill people. They are designed to launch a projectile. The only way that projectile can kill someone is if someone aims it in another person's direction. That'd be like me saying that a baseball bat is designed to injure a person because some people do use it as a weapon.

As for the bike and two-strokes. I see a ton of hybrids in the city of Atlanta and I see smog. 40miles out from Atlanta where I live I see 2stroke dirtbikes, weedeaters, etc and I don't see any smog. I think the solution is clear. Ban hybrids and smart cars.

Hi Chiapas

Looked at you greenspeed website!! and it was as I thought overpriced batteries overpriced electric motors overpriced Control modules all at rip off prices and made in Canada, whats wrong with stuff made in California or aren't there enough people with technical skills anymore where you live?

When will the greenies realise that if they want people to help the environment!! that they have to offer products at reasonable prices and stop ripping people off, and trying to make a huge profit

Batteries are not that expensive to produce and as for electric motors well is a hand full of Neodymium magnets laminations and copper coils!! Not $1500 dollars worth, sounds like someone is trying to make a killing to me

The remaining "fossil" fuels should be invested in producing long term, sustainable solutions that wean us from our dependency on oil. The fact new technologies require an initial investment and that our current way of doing things relies on oil-based economies is no reason to bury our heads in the sand, pint fingers, and then continue digging our own graves. This debate really transcends talk about smog levels or civil liberties, as it relates directly to our ability to survive as a culture, as a species, and as individuals. Your perceived "right" to do as you please is heading for a head on collision with peak oil, global climate change, and the economic and ecological chaos that will accompany them unless we take strong steps now and adapt to the new conditions.
By the way, I do not live in California, and I am not a "greenie", I am a consultant for the United Nations University and work very closely with climate change issues worldwide.
I am not suggesting you need to buy a 1500 dollar system for your bike, but if you want to build something yourself, why not invest in making a technology based on a new/sustainable paradigm rather than the old one that brought us to this point?

Sheesh. What was the original post about again??

Well... I've been keeping my mouth shut up until now, but since you're dragging out your credentials and showing them off... I feel the need to speak out. But first, here is some of my background just to show you where I'm coming from:

I've been an engineer for nearly 25 years. I've been a scientist for my whole adult life, and I hold a very pragmatic view of what technology can and cannot accomplish. I hold a master's degree in Systems Engineering, and I make a living by examining technical systems to identify any unforseen impacts, design flaws, or unexpected benefits. In other words, my job is to take the mystery out of technology and quantify its benefits and drawbacks so that the average business executive can understand why they should or should not pursue a particular technical solution. I have had a hand in designing everything from fish farms to RADAR systems that allow the United States military to quickly and accurately blow up bad guys.



...I am a consultant for the United Nations University and work very closely with climate change issues worldwide.

This scares the crap out of me. You show a very simplistic and idealistic view of the current capabilities of current wind and solar power technologies. I can see by your posts that you are a true believer, but you do not know much about the actual technological issues involved in using solar or wind power as a DEPENDABLE power source. I have seen nothing in your words that gives me any assurance that the UN should depend on your expertise for guidance.


...I am not suggesting you need to buy a 1500 dollar system for your bike...

Yes you did. The Greenspeed website that you posted is full of overpriced battery stuff that is not much more efficient than currently available 2-stroke engine technology. You even stated in an earlier post that 2-stroke engines were banned in California, but that isn't true anymore. The state allows for the use of new cleaner burning 2-stroke engine technology. When people think of 2-stroke engines, they envision the cheap Chinese units that belch filthy clouds of hydrocarbons into the air. But new 2-stroke engines can push a bicycle at 25 MPH for 150-200 miles on a single gallon of fuel... with greatly reduced emissions. That's clean power. In addition to being wrong about the ban, you are ill-informed about the technology as it currently exists.


...but if you want to build something yourself, why not invest in making a technology based on a new/sustainable paradigm rather than the old one that brought us to this point?

And my question to you is this: Why use a new paradigm just because it is new? Why should we strive to depend on a new technology before it is ready for prime time? Why not improve on the existing technology until such time that following the new paradigm is feasible?

The true believers never talk about the problems with their ideas... all I ever hear is how their paradigm will SAVE THE PLANET!! Well... this scientist isn't convinced that global warming is that big a deal. Hell... when I was in grade school 40 years ago all of the scientists were warning of the coming ice age that was going to cause famine and world chaos. I figure they're probably wrong again with this warming stuff.

When I look at the engineering aspects of wind and solar power technology as it exists now, there are many problems that make them undependable and horrendously inefficient. Don't get me wrong... I think that we should continue to explore the possibilities of alternate power sources, but we will never advance the technology until you admit that it isn't dependable yet. Instead, you want to force us to use it regardless of the impact to individuals and society. But you never talk about the problems.

Example:
Using wind power as an energy source doubles the community's demand for energy under the current technology.

Never heard that before, have ya? But it's true... here's why. Powering a community means that you must supply a constant and uninterrupted supply of electricity. When windmills stop turning and power supply sags... a backup power supply must come on line immediately. And the backup power supply is most likely going to be a coal powered plant. Now pay attention to what I say next... there is currently no way to store power on the electrical grid. What this means is this... that wind power must be 100% backed up by another dependable power source in case the wind stops blowing. But that backup power goes to waste if it isn't used... there is no way to store it on the grid for later use. So for every watt of wind power that you use, another watt goes to waste sitting on the grid. That means that you are essentially using twice the power that you'd use if you simply eliminated the wind power totally.

Your new paradigm isn't ready yet.

Oh yeah... I agree with Chiapas that we should all stop eating beef... pork is much tastier!

Re:- no method of storing electricity, or should I say correctly the means of storing energy to create electricty

I slightly dissagree, there is a plant in england, sorry well in fact wales that has been running for at least 40 years to my knowledge its based on a two reservoir system one high up a welsh mountain side the other some 750 yards down hill when electricty is at peak demand the turbines are increased by opening the valves to allow more water to fall into the bottom lake via turbines, when off peak during the early hours water is slowly pumped back up hill via the grid, therefore storing energy for the next peak demand

It is by no means self generative but it does solve peak demand problems!!

And I can hear you saying now what the feck has this got to do with bikes, but don't blame me Chiapa started it!!

Regards Stuart

That example is the exception rather than the rule.

The water in your example is simply used as a way of storing kinetic energy in the system... sort of a hydroelectric dam that lacks a natural river to power it. We have hydroelectric power already... but still no way to store electricity in the grid in any meaningful way.

The power plant in Wales is novel, but doesn't solve the grid storage problem unless we build an extensive network of mountains studded with pairs of lakes.

Hi Hydrated

I notice at the bottom of your posts a comment about Halogen

Do you have any experience of Xenon low voltage bulbs and the light output and efficiency compared to halogen?

I know its nothing to do with bikes unless you want to ride at night and have the possiblity of being knowed down by a drunk driver, but would appreciate any light sorry about the pun you can shed on the newer gas in bulb envelopes!!:)

Regards Stuart

I have nearly lost the drift myself!!

I may think about a Jet turbine bike instead just to throw the cat amongst the pidgeons Tee Hee

So why doesn't some company design a small 4 stroke engine based on Hydrogen fuel say 50cc or there abouts so people can get about a bit faster and only produce water as an exhaust bi product,

Ahhh I forgot it will take electricity to produce the Hydrogen so thats a real bummer isn't it!!

Stuart

Do you have any experience of Xenon low voltage bulbs and the light output and efficiency compared to halogen?

I haven't fiddled with the Xenon bulbs... mainly because of the influx of insanely cheap LED's that put out big light. But if you want sheer power that will singe your retinas... go for a 20W halogen and over volt it by about 20%. I run two 12V motorcycle foglights with 20W bulbs in them... but I run them at 14.4 volts.

Trust me... if you can't see with that kind of light out there, then your eyes aren't open!

I'm moving to LED stuff soon, though. I can now build or buy LED stuff that runs on a 6V dynohub that lights up the road nicely. And no batteries to recharge.

OK, 'bout time I chimed in on this subject. Back in college (BSME) I developed a cool motor drive unit for my 10 speed. Worked real slick. Cost me a total of around $150 and a bit of elbow grease and clever design. It used a little .75 HP 2-stroke engine, and applied the power directly to the bikes own drive train. This gave me 10 gears to use in conjunction with the engine. Keep in mind, these little motors have very narrow power bands and spin at high RPMs, so your first challenge is the massive gear reduction required to the wheel, and your 2nd challenge is being able to alter that gearing so that the motor is in it's power band at slow speeds and at high speeds. Here's how I solved both for cheap:

Gear reduction: I took an old Sturmey-Archer 3 speed bicycle hub, which is basically a planetary gear drive, and modified it to provide 4 to 1 reduction. I did this by driving the sun gear with the motor, freezing the ring gear to the hub with JB Weld, and taking the power output from the planet gear carrier. I had a simple V belt drive from motor to hub, and a chain drive from hub to front sprocket.

Multiple gears: I added a 3rd sprocket to the peddle cluster and applied the modified hub output to it. This allowed me to use all 10 gears with the engine. Worked great, I could start out and crawl up hills in low gear, or get up to 40 MPH on the flats using high gears, all while keeping that little engine in it's power band. "But Wristwister" you're saying, "isn't it a pain to have your peddles spinning madly while under engine power?". I came up with a clever solution to that too. Back in the '70's, Schwinn made a 10 speed bike called the "Freewheel" (or something like that). Instead of the rear sprocket cluster freewheeling, this bike was designed so the front sprockets freewheeled. The idea was that this allowed easier gear shifting, as you could shift while coasting. So I was able to order the front freewheel assembly from Schwinn, and I made a custom peddle shaft to mount my new triple sprockets onto the freewheel mechanism and onto the shaft. Worked great, I could peddle and/or motor at will, chain was always in motion for shifting, yet the peddles would freewheel.

Anyway, I used this contraption for a few years. Worked great, got lots of strange looks.

Good luck with your project. It CAN be done, it can be done cheap, and it can work great. Just gotta get creative!

Very slick solution!

Good thing you didn't let an Electrical Engineer design it... the system would've been 4 times as complicated and half as dependable!!

Well, thanks to your adamant responses I've actually gone back and re-read my own posts in this thread. After weighing the different opinions expressed here, I have to say first off that I have never been touting wind or even solar power as a blanket solution, I merely pointed out that the servers at the university where I am currently posted run off these renewable energy sources. I do stand by my previous statement: "The remaining "fossil" fuels should be invested in producing long term, sustainable solutions that wean us from our dependency on oil."
I am well aware of the current limitations in terms of our energy storage capacity, but as pointed out in this thread there are more than one viable alternatives which have not been developed due to a lack of funding and a stalwart opposition of Old Paradigm industry leaders protecting their interests.
Hydrated: your obvious glee at "blowing up the bad guys" and your shortsighted denial of human induced climate change are very revealing of your level of critical thinking and strongly detract from the stronger points in your argument, lets just leave it at that.
What does all this have to do with bikes you say? As the most resilient and viable alternative to the internal combustion engine for urban and sub-urban transportation, I would say a great deal. This is the reason I find the proposition of taking a purpose-built human-powered machine and converting it to a gasoline burning Frankenstein very distasteful indeed.

Hydrated: your obvious glee at "blowing up the bad guys" and your shortsighted denial of human induced climate change are very revealing of your level of critical thinking and strongly detract from the stronger points in your argument, lets just leave it at that.

When someone uses the phrase "let's just leave it at that" it's normally because they realize that their argument is pretty weak and they need to disengage quickly lest they be embarrassed... But that's just my lack of critical thinking skills talking.

*sigh*

It is also a way of saying "my intention is not to offend you personally so I will keep my comments about your opinions to myself".
In all seriousness, I exhort you to take a close look at who you think these "bad guys" may be, why they need to be "blown up" and who got you to think that way.
Also, please read the latest reports from the IPCC with an objective an open mind: http://www.ipcc.ch/
In regards to your siggy, I have this for you:
German lights use Lux to measure output, which I think measures light in a square meter 10 meters from source the results;
IQ Fly 40 Lux
Supernova E3 60 Lux
Schmidt 80 Lux
The best 3W halogens are around 25 Lux [/color]

Supernova E3 60 Lux

Ohhhh... I get all a-twitter when someone talks lights to me:

When you go out and quote all of those numbers comparing popular LED lamps to halogens, you are making a key assumption that is wrong. You assume that I'm following the rules. I like to think outside of the box... and the only rule that I adhere to is Ohm's law. And I'd break that one if physics would let me!

First... who the hell uses a 3W halogen? Not me... if you'll read my posts, you'd see that I run a pair of 20W MR16 bulbs. The only reason to run a 3W halogen is if you're using a generator hub... and halogen isn't the best choice for use under the relatively low voltage/low current output of a dynamo hub. LED's are better there.

Second... I don't run my bulbs at the voltages that they were built for. I break the rules... run them at their proper voltage +20%. An overvolted halogen will put out crazy light levels that way. I run my twin 12V bulbs at 14.4V... and I challenge you to find a brighter light for the price. My system cost me about $40 to assemble. That's bang for the buck.

Third... I own a new IQ Cyo LED light. So I know what the light output is from those lamps. They don't touch the output from my halogens, but they have other advantages. Like they run off of a generator hub, so no batteries to recharge. But for sheer light output at a low price... no contest. Halogen wins.

i guess I was assuming we were talking about 6v 3w generator hub run lights. my mistake.
in general terms you are absolutely right and i congratulate you on an impressive light setup.
i am currently waiting on my Edelux set to run of my shimano dynohub....

i am currently waiting on my Edelux set to run of my shimano dynohub....

The Edelux is a sweet light... but I was too impatient to wait for one. I bought the new IQ Cyo to run off of the 3N80 Shimano hub... works nicely... lots of light for a hub driven light, but the Edelux has a much nicer housing. The IQ Cyo has great output and optics, but they kept the price down to near $100 by using a plastic housing.

Okay. I keep seeing this "global climate CHANGE". What happend to "Global Warming"? Did all the snow storms at the Global Warming protests kind of make your product a little tough to sell? All this "Green" crap is just as useful and dependable as a green crap. This "Green" stuff is nothing more than a united power grab by a bunch of lost communists who have nowhere to go since the collapse of the Soviet Union. So they hide behind the enviromentalist (which can be a legit movement) movement since anyone who argues against it is an "Evil Person". It's almost like the "Think of th children" argument. Good luck saying "Screw the children".

I love mother nature and I live in the country with mother nature and all of it's splendor. I'm not some joker who lives in a concrete jungle and then comes 40miles out to ride a dirt path that is so smooth and maintained it's a step away from being paved. Personally I think we could detonate every single chemicle, biological, conventional and nuclear weapon from every country in the world and despite all of us would die that in maybe 100-200 years it'll look like we were never even on this planet. I find it insulting to nature that we think that we are even a blip on the Earth's radar.

Now us bikers like to pretend we love mother nature. But I find it amusing that while on my mountain bike rides I see little used gel packs laying around the trails along with other trash (such as CO2 shots) that is clearly bike related. My redneck cousin from south Georgia threatend to beat the crap out of me for throwing a candy wrapper out of his truck window years ago. Which is also why I never throw trash out my window anymore.

This thread got amped up (hehehe). OP, the pic of your finished product reminded me of this: http://i43.tinypic.com/2nren14.jpg
