Chainsaw powered bike : LUSENET : Junkyard Wars : One Thread

I was thinking of making a powered bike with a chainsaw or weefdwacker engine. I would run a chain from the chainsaw mounted over the rear wheel, to the front gears, then I would be able to have (if the bike was a 18 speed) 12 gears to run with, so I would be able to reach some pretty decent speeds. The cranks would be attached regularly (I would use a 3 piece crank) and drilled with pins in the holes, that way I could pedal too, if i ran out of gas or something, or to conserve gas. Soun like a good idea? I do. Email or post any comments/questions/past experiences/ideas/hints

A chainsaw and weedwacker are made to run at high rpms but not for very long piorids of time. But u may find that u may lose power on hills. if a saw is run at a too high rpm for too long it could be dangerous alllmost like a hand garnade so try to keep this in mind when going up hill.

-- Phast Phil (, April 13, 2003.

I saw this problem also, I was planning on setting the throttle so that it wouldnt run at wide open, something lik 3/4 throttle, and having some kind of switch so that my throttle would be able to go to full open if I needed it.

-- TJ poseno (, April 13, 2003.

you could not use a weedwacker engine you would have to have a chainsaw because a weedwacker engine has no type of clutch and not powerful enough but it will probaly work with a chainsaw because it has a centrifical clutch and it would be easy to hook a chain to

i put a leaf blower engion on my huffy moutain bike. i mounted a bike peg to the engions drive shaft and used a friction drive with no clutch. it goes 20mph down hills but has no power to go up even the smallest hill. how can i get more power out of my 21.2cc mcmulloch blower/vac engion?

put answers below

I wouldnt use frriction drive, but anyways, I would just help it out a bit with the pedals, There really isnt anything you can do to such a small motor thats worth it. Id get rid of the friction drive

i just took the muffler off of my mcculloch 21.2cc blower/vac that is on my bike and i got lots more power out of the engion. what caused this?

i thought if taking the muffler off of the engion would increse power there must be a different muffler i can put on my engion to increse the power without all the complaints from neighbors.

is there a power increseing muffler that i can put on my motor that will keep noise to a min.?

I was also thinking of building a chainsaw powered bicycle.Could someone please send me some plans including the required Horsepower and torque to RPM ratio. I want to be able to mount the engine over the back tire.Actually, it doesnt have to be a chainsaw engine, but it would be convenient to use on original chainsaw chain, remove the guard and attach a sprocket on the left side.i would also like to know how big the gear will have to be on the back wheel so that it doesnt stall while going up hills. I have a 21 speed mountain bike with wheels about 24 inches. Some other questions are, do chainsaws have some kind of a variable clutch, would i be able to pop start it and how would i stop it from dieing when i want to gun it and try to accel fast. Also would i want a 2 or 4 stroke. I would like to be able to detach the chain and pedal if i were to run out of gas.

Hey gidday to all, im a 14 year old who has a need for speed so what do yous all think of about putting a whipper snipper engine on a bike. My bike is a 16 inch i put on chrome wheels and shit it looks real good. Anyways i was thinking about buying a bag holder for the back of the bike (one of the chrome ones) cut it down to size to go on the back and then putting the engine on that(bracing it down and shit) And then have a chain running off the engine and straight down to the back wheel cog. Then running a accelerator cord to the handle bars and put the little pull trigger that comes with the back cog is one of the ones where if u push back on the pedals the wheel locks up i think there called coaster brakes or sumthing.

Hey dudes, I'm 39 and have been wanting to put a chainsaw on a bike for years. I took a thrown out mongoose frame and streched it 11'' in front of the back tire. I plan to machine the clutch and fit in a #35 chain sproket with 12-13 teeth, then run it to a big sporket , #35 in the front on the crank, @ 30-40 teeth or more.After that I'll run off of the smallest of the 3 to run the back wheel. On the nack I plan to use a 5 speed rearend for some gear range. Also I plan to water cool the engine so that it can go a good distance with out burning up. what I 'd like to know how to do is get an electric starter for it so that I don't hav e to crank it by hand let me know what you guys think.

ive got a g scooter....same priciple tho with the chainsaw engine,only problem is...the clutch is not grabbing the driveplate...i already know now that this is a cenrifugal clutch which are not designed to be taken on soft ground or up steep hills...bare this in mind before you try and attatch 1 to a bike otherwise youll be replacing clutch pads every week!!!

-- arun (, November 03, 2003.

If you put a 5 speed rear end on it , you may then have some gear ratio to playwith and then not tear up clutchs to bad.

-- tom watts (, November 03, 2003.

First off you need a new bike, get rid of that 18 speed and look around for an old 6 - speed bmx or 3 speed custom bike. Disengage the pedals and the bearings and fit that chainsaw (40cc or higher, a weedwacker is insuffiecient, i tried a weedwacker and my 185LB body didn't go nowhere, ESPECIALLY uphill) into the gap created. Make sure there is enough room to fit the engine into the slot where the pedals used to be. You'll need to buy a bit or peg for the engine that's small enough to fit through the slot. Then get a medium sprocket 30-40 teeth and drill a hole through it's center, make sure it's a steel sprocket. Then push the engine with the newly installed bit/peg into the hole created and weld them tightly together, use excess iron for a stronger bond. After that you must weld on a suitable mount to hold up the chainsaw engine, making sure to leave room for cables and fuel tank. When this is done get a chain long enough to wrap around your 30-40 teeth front sprocket onto the sprocket attached to your back wheel (any gear it doesn't matter but start at a low gear to be safe). To modify the tiny throttle cord on your chainsaw just pull off the cap and weld more cord as need, you can find the metal cord at most hardware stores. I attached that throttle cord onto an old twist grip gear and attached it to my right handle bar, i couldn't find a regular throttle grip. Attached this way that chainsaw can take you up to a good 40mph depending on your weight and engine displacement. I used a 46cc engine, but DO NOT expect much out of it uphill.

-- Bob Bromleto (, November 05, 2003.

Hey guys... I'm building a chainsaw bike right now. Not finnished yet. I took the pedals completely off because I don't like pedeling anymore. Mounting the engine is not too hard. i stretched the rear triangle about 8 inches so I have more room back there. Then I used the original chainsaw bar handle to weld on a motor mount. I'm also using the chainplate (whatever it's called) mounting holes to hold it on the opposite side. I've had to fabricate several parts like a BMX freewheel with small mountain bike sprocket, attaching a sprocket to the centrifugal clutch and making a new air cleaner/manifold. As soon a I get a web site put up, I'll post pics of my progress and finnished product as well as other bikes I've built/am building. Do any of you have pics of your projects? If so, email me. I wanna see what else is going on in the world of home fabrication.

-- romi jash (, November 23, 2003.

Hi guys, I don't know if any "plans" exists for a chainsaw powered bike. The cool thing about a chainsaw on your bike is that you build it from your own ideas, not plans that makes your bike look like someone else. Befoe you do anything, sit down and draw up ideas on paper. It's easy and cheaper to just errase pencil lead than to cut off welds. Then get materials together and get creative. get it together and running, then disassemble and paint it last. Keep this one thing in mind when your designing and that is to include some gear range. A 3 or 5 speed rear end, 5 speed would probably be better. Thing about this, How many cars are made that run from the engine to the rear end without going through a transmission?? The answer: NONE!! You guys that are having trouble, especially up hill, think about it!

Have fun! Tom Watts

the optimum engine would be a STIHL 4-MIX ENGINE. It is a four- stroke engine that runs on a gas/oil mixture. It has valves like a four stroke, put part of the gas/oil mixture is diverted to pass through the crankcase, so there is no need for an oil reservoir. The end result is a four-stroke engine that can be turned on its sides without destroying it. An article on it was in the last issue of Popular science and more information can be obtained at

My Brother mounted a Victa 160cc Lawnmower engine in his mountain bike. Some of the problems encounted were vibrations as the engine had no flywheel & finding a high enough location 4 the fuel tank as the engine was mounted where the top cross bar was. He had all of 4HP to play with so he did it wisely. He scavanged the local tip 4 sprockets, chains, etc.. The engine drove a 12 tooth sprocket which inturn spun a 38 tooth sprocket on the LH side of the crank. The RH side of the crank spun a 12 tooth sprocket powering a 38 tooth sprocket on the rear wheel. The bike also had 3 gears inside the hub. The easy part was staring it with the pull start & the rear wheel raised. The suicidal part was jumping on it, as it had no clutch. It would launch in a very violent manner. I clearly remember my brothers words after his first ride "Its a danger to society & mankind". The bike still hangs in his Garage as memorabilia of his teenage years.

Hey all.

I built a chainsaw mountain bike this summer. You may have seen it on daily planet, on discovery channel. Jesse james came to Toronto, and I brought my bike down there. Discovery channel asked to interview me, and i got on tv.


-42 cc. poulan chainsaw engine -home made engine mounts -home made bearing mounts -3 chain gear up assembly -original clutch modified w/sproket to use roller chain -chopped pedals (no need for pedals now) -motorbike handlebar throttle assembly... -high grade, heavy construction of all parts, except original bike components which are weak.. ie sproket sets.. brakes.. hehhehe.. brakes.... heheheh..

-Does 60 - 70 km/h on flatland.. -Needs belt drive on the outside gear assembly for safety and performance reasons... -Chopper like monster style.. -Needs front Shocks..

email me if you want to see pictures. or ...

go to -- if this link doesnt work, go to, and search for jesse james. the clip is called "Up Close with Jesse James (Video - Daily Planet)".

I plan on making a model that can bolt on to any bike, and maintain its existing gear system like this one. being able to use the bikes gears is what makes this an efficient vehicle.

Be careful people.. I got in an accident on mine already... chain flew off and beat my leg.. lots of internal bleeding and internal scarring now... and i didnt have my helmet on at the time.. so a reminder to the kiddies and even the grown ups.. BE CAREFUL... BE SAFE...

and above all BE CREATIVE!

-- beau (, January 30, 2004.

I am trying the same thing w/ a McCulloch 40cc chainsaw. I am going to put it an a small trick bike and I have a good idea and hoow to attach it. I'v already started to extend the shaft so that it will be longer. I am bolting the motor to the side of the bike so that the extended shaft will go through the hole where the pedals and pedal bearings went.

-- Mike (, February 05, 2004.

I want to just use the shaft and sprocket without using the clutch. A centrifugal clutch just wouldn't work!!!!! You would have to rev up the motor and hold up the back tire and then jump on ect... If u take off the clutch and attach the sprocket right to the shaft then it will give u 40% more power and more speed. The only problem w/ this is that once u start it it will start to move slowly so be careful!!! In order to fix that all u have to do is turn down the idle. it is really easy- it is a screw that should be near the carburator.

-- Mike (, February 05, 2004.

why would it be 40% better?

hi im wondering what would be best to make : a motorised bmx or a go kart. i have the option of using a lawn mower engine or a whipper snipper engine but am not sure what to do. i would have to make the whole frame on a go kart compared to tonly the engine mount on a bmx. the lawn mower engine costs $75 and the whipper snipper $60. i was also thinking of saving for a 35cc chainsaw engine but that would cost about $200 =( any help on what to do would be appreciated, either by email or by reply post. i also have msn messenger if anyone else out there does.

Hi, I want to put a 50cc wiper sniper motor onto my bicycle. it is one of those bikes with 2 suspension shafts at the front and one shock and suspension directly under the seat. I want to hook it up with a chain directly from a sprocked mounted on the motor shaft to the 6 gears down the bottom on the wheel. I also want to change these gears for up hill power torque and top end speed.

this 1's 4 abuv if u attach an engine by engine shaft 2 da pedal gears the sprocket on da engine shaft will b bigger than da 1 on the actual wheel meanin ther iz less rotational tork on da wheel rather than wot da engine iz actualy producing-also if da wreels iz big it normaly means that ther iz less power more speed.however 2 overcum dis problem make da back sprocket bigga than da 1 attatch 2 da engine shat 4 more lower,powerfuler tork.Oh, and dont say were legends it makes ya sound like your likin ass.

Ok kids, I know where you're all coming from. I'm 56 yrs. old and I used to make what we called "doodlebugs." A doodlebug was a 20" or 24" Schwinn bicycle with the pedals removed. We had a local lawnmower shop weld a piece of 1/4" steel plate, big enough to fit the bolts on the bottom of a Briggs & Stratton or Kohler lawnmower engine, on the frame, above where the peddals were. (The rich kids used chainsaw engines.) The holes that bolted the engine to were elongated about 1/2 inch to be able to adjust the engine back and forth for proper fan belt or chain tension.

We attached a go cart or mini bike clutch to the engine shaft. We also had two brackets welded to the frame, behind the engine. These brackets contained two automobile wheel bearings and a "jackshaft" between them. The jackshaft had two chain sprockets on it. (You could adjust the size of either sprocket for hills if necessary.)

Finally, we had a larger sprocket, about 10 inches in diameter, welded to the original chain sprocket on the rear wheel. Then, we ran a chain from the clutch to the jackshaft on one side of the bike and from the jackshaft to the rear wheel sprocket on the other.

Add a motorcycle twist grip and dummy side (looks like a twist grip but is just for looks) and you're off. You'll need hand brakes from any bicycle, but at the speeds you're going to putt, they're not going to do you any good. I eventually bought a Whizzer moped wheels and used the drum brakes to stop.

You can pull some good speeds, even with a lawnmower engine. I got a ticket going 45 in a 35 mph zone when I was 12. My dad took me to court and when the judge read the ticket he threw the case out. The ticket said "type of vehicle," Schwinn. The judge said no bicycle could go 45 mph and I got to go home. But, I lost use of my doodlebug for months afterwards.

If you'd like to see pictures, I have some taken when I was about 16.

Have fun and don't kill yourselves.

you need to add a coaster/freewheel ans 2nd set of gears to free up pedals or you stuff won't work if you use the stock chain if you like custom work make a transfer gear

pedals to transfer motor to transfer transfer to rear gear place freewheels in appropriate direction on pedal input and possibley motor input if you want to save clutch wear use friction drive if you cant figure out the rest oh get a large gas tank with oil injection if 2 stroke from boat they work great also trikes adapt way easier than regular bikes as pull starting while driving was a problem on the first bike i made ( a 10speed road bike with friction drive weed whacker motor )

Im currently building a motorised bike (mind the spelling, I'm from Australia) using a Husqvarna edger engine (30.8cc). Has anyone ever seen the small rollers they use on boat trailers? Well that's what I use to put the power to the tyre. Boat rollers are much cheaper than tyres. It is also essential that you find an edger engine or weedwhacker as you call it with a clutch. Otherwise you won't be able to stop without the engine stalling.

chainsaw bikes are very popular now in the racing world. they are known as pocket bikes. Check ebay out for them, i own one and its awesome. As far as how it works.. They use a 47cc chainsaw engine with the clutch and single speed gearing. it is usually geared 6 - 68 or somewhere in there. good luck building one on a bike, it sounds like fun. One thing to remember though, if you leave the crank on the bike, when the bike gets up to speed you will be peddling VERY fast.

I'm 29 and in the middle of fabrication on a chainsaw-powered bicycle. I picked up the Poulan Model 1975 33cc(?) for $60 at a pawn shop. The bike is a 26" Magna. I'm trying to see if it is possible to keep the chainsaw's friction clutch intact for smooth acceleration.The chain sprocket is perfect for driving a 3/8" V- style automotive belt. I am current scavenging and assembling the transfer mechanism. I plan to use a idler pulley off of an old model Chevy or Ford (to receive the belt) welded to an adapter plate to hold the bike sprocket jewel. I will be able to add an additional derailuer later. As for throttle, I have found that an additional set of hand grip brakes on the bar works fine (and it's cheap). They come in sets of 2, so one can run throttle and the other can be for the engine kill switch (required in some places). If anyone has done a similar set-up/fabrication, all advice would be appreciated... I will add posts as things progress. Wish me luck.

my bike has been clocked at 80kmh and since then i have added a new pipe and a smog pump supercharger and as well changed the sprocket the chainsaw runs to to a 48 tooth from the 44 tooth which helps the last gears go faster lower gearing matches the pedals a little better - MAKES FOR BETTER TOP SPEED IF YOU CAN PEDAL - i got the smog pump supercharger from an old nissan 300z - it was a waste of time i haven't tuned it yet tho - it does have potential as far as gears go - spend the time figuring it out as you will suffer if you just hack it together. this bike is far from a rocket!

I'm making a chainsaw bike so i can do sum burnouts on the school field and I'm halfway through it. I started by giving the bike a narly paint job then set about finding a chainsaw. It took me 3 days to get 1. U can usually find one in ur local buy/sell/exchange newspaper 4 about $20. Always buy a broken powerful chainsaw rather that a more expensive unpowerful working one because they r easy to fix even if u no nothing about chainsaws. i got that far with a chainsaw but i cant figure out how the chainsaw will idle (run in a neutral gear). It also will not start with the choke pulled out. The choke has to be left in to start it. Wat is wrong here? That is all I need to know coz i can weld and do the rest myself. any help would be greatly appreciated.

I have an old 15spd mtb i used to use as a hack bike. I am experienced in machine mechanics and work with tools alot. I want to motorise this bike. I would be willing to buy a smaller / different bike. I am having trouble finding a suitable motor and how to fit it. A chainsaw around here aint cheap and a whippersnipper maybe wont be powerful enough. I need some plans please email them 2 me. I came up withmounting a luggage rack on the back (the ones that hold cardboard boxes - springloaded) mounting the engine to it and fitting a cog to it and run it to a gear below - im stoked how i can run it with the use of gears as i dont want to buy a kit nor can i weld (well i can but have no use of a welder) and i dont know what gear ratio to set the bike to or how to perfectly stabalise the engine. If anyone has any plans please email them to me and ask anything in return (am not willing to spend a large amount of money on parts) Thanks, Ryan

As above. Just bought a weedwacker 2 stroke dont know how many cc's. I have cleaned rebuilt and lubed it and need some petrol intake tubing which ill get from the harware store. then motor spindle is not how i imagined it. i need plans please people Thanks, Ryan

-- Ryan (, January 27, 2005.

It sounds like a good idea to me but you should definatly use the chainsaw motor because the weedwacker motor would not be powerful enough.

I was also thinking of making a chainsaw powered bike. I have the motor and it will run (if I had some 2 cycle gas and a gas tank)but I dont know how I should mount it. It's a 37cc motor so it should have enough power to move with me on it, I only weigh 87lbs.

This has nothing at all to do with the subject but I just found out how to make a bomb! Setep1:Spray some hair spray on a hard surface (preferibly marble so it wont leave a black mark).

Step2: Light it with a lighter and put a cup (NOT GLASS)over it.

Step3: When the fire goes out then check and make sure that it is stuck to the table.

Step4: Tie some yarn around it and carry the line off at least 10 feet away and get behind a protective sheild (or at least wear goggles.

Step5: Jerk the yarn and the entire cup will explode!

I found this out on accedent.

I undertook a project to make a minibike for my nephews and first tried a homelite weed whacker engine. I welded a sprocket to a 1/4" square shaft to drive a jackshaft that in turn had a v-belt to the back wheel. This v-belt had a 2nd pulley that would act as a clutch as the weed whacker didn't have a centrifugal clutch. The problem I hit was that the engine was not powerful enough at idle to drive the chain and jackshaft and would only deliver power at high rpm. Its the high rpm requirements that had me utilize a jack-shaft in the first place as my nephew is only 6 I didn't want the little guy flying around at 60km/h! I ended up scrapping the homelite engine and bought a 3.5 hp Briggs and Stratton and putting a governor on the throttle. The frame was an old school type kick scooter with 10" wheels. I cut the wheels off and put on fat trolley wheels (adding 6" to the forks) and xtended the back axle out 6". I have to finish putting the seat on and some minor paint and welding and it should be done in time for his birthday in May. If anyone wants pictures of teither the weedwhacker version or the B&S version, just drop me a note. I am still interested in making a little minibike or powered skateboard with the homelite or a chainsaw engine (since they are just sitting in the garage).
