3 wheel bike run by a chainsaw motor?

greenspun.com : LUSENET : Junkyard Wars : One Thread

How would I get a 3 wheeled bike to run off of a chain saw? All I have is a bike, example: http://www.ajobikes.com/3_wheelers/miamisun/miamisun1.gif and a chain saw. What else do I need? And how would I do this?

The easyest thing would be to bolt a small grinding wheel where the chain went on the saw ,and have it rub directly on the tire. a lot of aftermarket bike motors use this system. Solex still uses somthing like that.

a griding wheel r u stupid just bolt a small sproket on the saw and hook it up to the chain hook the throttle up to ont of the brake levers and go

-- brett ahrens (demonspike1234@aol.com), June 12, 2003.

you all are stupid becuz you would have to have radical gearing for the bike to move with a chain drive and you couldnt use the stock clutch

i used to have a motorized bike that was driven straight onto the tire and it had quite a bit of power but i have a scooter with a whiipy engine now and it goes alot harder and i can change the ratios

im making a motorized scooter for a school tech studies project i was wondering if there were any suggestions as to the best motor and stuff to use. any info or links etc would be much appreciated. possibly in lameman terms as this is new ground for me. CHEERS!

-- Jen (jellybaby_56@hotmail.com), January 30, 2004.

you can use a weed wacker motor and place the spining part on the tire, just get thick flatland tires or something, its really fun on a bmx bike

Wat would ba the best way to mount a wiper sniper motor on a scooter using sprockets and chain or just but the spining part on the tyer??

-- Cameron (burp01@hotmail.com), March 17, 2004.

Let's think about this. An average bicyclist might pedal the crank around 80 RPMs which produces say 20 MPH using a 48 tooth crank sprocket and 13 tooth sprocket on the rear hub using 27" wheels. For comparison, let's say a 2-cycle engine spins at 3600 RPM. Using this same gear setup, we would need to gear down the motor 45:1. If we go ahead and change the crank sprocket (mounted on the engine shaft) from 48 teeth down to 12 teeth, we only need to gear the motor down to 11.25 to 1. Now rather than using a 13 tooth rear hub sprocket we use a 28 tooth rear sprocket. This means we only need to gear down the motor 5.25:1. Using a smaller diameter rear tire would bring this ratio down even further. It just so happens that Staton-Inc. makes a 5.33:1 gearbox specifically for this purpose and is designed to bolt directly to a variety of small engines including Honda GX31, Robin EH035 & Mitsubishi 40.6 cc.

i am making a motor scooter and i want suggestions on what motor 2 use

-- galen (GKir25@netscape.net), April 14, 2004.

I have an old 33ccm chainsaw motor that i am trying to put on a dyno, its got a cut down frame, I am mounting it above the wheel in the back and running a chain rite off the chainsaw to the wheel sprocket, i was wondering if this will, work and also any suggestions on where to find a bike chain sprocket and clutch assembly that will go on the drive shaft where the old on was, ohh and will i need to gear it down, email me with any suggestions please

-- Dan Henline (bendover43@aol.com), May 25, 2004.

i have a gas motor scooter that has a 43 cc engine on it right now. the engine that is on it right now is really slow and doesnt give me the power that i want, so my dad gave me his 2.3 Cubic inch chainsaw motor. i already figured out how to mount it onto the go ped, but i was wondering if i take off the stock clutch that comes with the chainsaw that is used to spin the chainsaw chain, and take that off and weld on the actuall sprocket that drives the tire sprocket, would it work? or do i need to have a certian type of assembly for it to work? please please eamil me if you have an answer. thanks

-- Willie (william_hoffman@hotmail.com), July 29, 2004.

This is for every one!!!!! Yes I have plans for a chainsaw powered bike! It took some time (2 years) but now there done. The plan is for a chainsaw powered bike and it does work guaranteed because I built one myself that works like a charm! If you want plans just e- mail me.

If anyone has plans to installing a wiper sniper motor to a bmx could they please email me.

-- Randall (dougie_coopers@hotmail.com), August 05, 2004.

this is for everyone. none of u should use a weed wacker motor, no matter how u set it up, it is crap. u can barely move, and if u come to even the smallest hill, forget about it. i recommend using a chainsaw motor, or maybe even a lawn mower motor if u have acces to it.

can any help me out i want to know how to make a motor scotor using a weed wacker

-- Ross Moran (ross_moran_8@hotmail.com), October 08, 2004.

Why do people ask for plans? It doesn't make any sense. You just have to figure it out..I mean, if you are using stuff you already have, just make it work. Get sprockets, make them line up, try different gearing, build motor mounts so they hold your motor in the right place, and make a throttle system. It's not brain surgery...trying to follow plans will be much harder than just using what you already have. I built a go cart, with a-arm suspension in the front, a solid rear axle with a sprocket and brake disc in the middle, using a B&S 5hp. The thing wouldn't even climb the driveway. So I got a YZ125 motor, and dropped it in...changed what I needed to change...it's seriously not that hard. Just go one step at a time, and figure out each step as you go, and slightly look ahead. Here are your plans, no matter what you are making:

-First you need to make a rolling chasis. A bike would already be considered a rolling chasis. -Then figure out where the motor will go, so that the chain/belt lines up. -Mount the motor. -Invent your own throttle linkage.

Test it, and ride it. Plans Shmlans.

Anyone that have blueprints for scooters... send them to me, please. i wan't to see as many construction as possible before i start to plan my own scooter.


-- Gustav Bengtssnoq (gustavsbusiness@hotmail.com), November 18, 2004.

u need a 12" tire, (u only need one tire to power. Change the sproket on the chainsaw to a 22-32 toothed sproket. then u will need to find a chain that will fit. u can mess around with the gear ratios to get more or less power. i suggest u start moving befor u gun it because the clutches are prety weak

-- matt bonner (mofo45_64@hotmail.com), November 22, 2004.

i was thinkin about doin a motorized gt snowracer it has the chassi and shit but then i scraped that idea an am gonna build a motorized lowrider bike i can get the lowrider bike for like 20$ gotta love the banna seat and use a rear wheel off a 5 speed bike and take off the thing that changes gears cuz the chainsaw has a clutch so jus let off the gas and change gears but ya im outty peace
