homemade chainsaw bike!

[LiTtLeRaven687]

What did u use for the pipe that spins the tire?

[fairyheli2]

so thats a clockwise engine?

[bazengao]

thats the most stupif way to trasmit power the wheel...

[gymkhanable]

Probably go backwards?

[fairyheli2]

what's on your friction drive roller? do your tyres last?

[geoff390]

@fairyheli2 this one was a knnurled pattern made on a lathe. This setup did chew the tyre but then i went to a splinded pattern similar to  a goped spindle.

[fairyheli2]

@geoff390 what do you mean by splinded?

[geoff390]

@fairyheli2 similar to the tailshaft on a car, has grooves parallel to its length.

[theclockmax]

you you do all that. you could just have gotten the mechanism of the chainsaw which makes it turn and connect it to the bike chain or tire

[driftboy98]

@theclockmax nooo it will slip!

[theclockmax]

@driftboy98 not if tight

[driftboy98]

@theclockmax has it sliped on u once??

[theclockmax]

@driftboy98 no. it cant cus its bolted in

[JRBugge]

Dude.. this is awesome!

[spider6837]

thanks for the adjuster idea

[mashersmasher]

you need a better system. that tire is going to cook

[1mic1beat]

ths is some dodgy shit. your little motor there is gonna cook. its goin to be doin too much work

[remdog1231]

whats a good ratio for a chain drivin chain saw bike....is 12t on the clutch to an 44t on the axle good?? i need to no

[geoff390]

@remdog1231 no where near good enough for what you want. You need closer to a 12:1 ratio for a chainsaw. Remember small engines have practically no torque hence the high ratio needed.

[geoff390]

@diesel5355 its just held on there by the reverse nut taht held the clutch on

[diesel5355]

@diesel5355 

[kvni1965]

That is amazing, great job, I wish I had that talent. 

[fairyheli2]

i made one but it was a nightmare to turnover, needed someone to push me to get the motor started

[drgnforce44ever]

thats gehtto

[Gauntletbloggs]

Lol "probably" go backwards, id be leaning toward definitely. also why use a spindle system? why not just mount an appropriately sized sprocket on the rear and drive it off that? the system looks kinda like youd be struggling to transfer power and/or put stress on the motor due to constant upward pressure on the output shaft. you could still disconnect it just the same with the tensioning system you are using. seems like an odd design tbh.

[geoff390]

@Gauntletbloggs spindle designs are used on most gopeds. I do agree that it does put a lot of stress on the bearings. with the correct size and design of spindle i did eventually get good power transfer.

[inkybait]

@geoff390 when the chainsaw is idling will it let the spindle turn? if so how smooothly?

[geoff390]

@inkybait when i was idling i had to pedal to help keep going. It was quite smooth i guess.

[inkybait]

@geoff390 oh kk thanks! also if im using gears would you know what ratio to use on the gears?

[shawndw151]

@inkybait I made one, and i used a 12-1 gear ratio....if you live in hilly areas though, id go up as much as an 18-1 gear ratio

[myautofarm1]

how many cc?

[geoff390]

@myautofarm1 around 30cc.

[noicewater]

That thing is bike is hurt

[geoff390]

@noicewater Wow nice english, i know some of my sentences arent 100% correct but fuck me dead!

[fairyheli2]

how did you make the spindle??

[geoff390]

@fairyheli2 on a lathe

[prestonkillz]

you probably should have put rubber on that shaft to make it grip better and your tire wouldnt have been so dead. how fast does it go?

[geoff390]

@prestonkillz the second spindle was much better. Around 30kmh

[Domnaek]

you havew a very gay voice

[driftking9293]

not bad but you can do better

[airsearescue]

Saw similar set up on a french bicycle circa 1913 nice job you got off your a?@e and did it well done. I live near the sea and i am adapting a industrial petrol strimmer with a propeller on the end to use on my stand up paddle board.

[geoff390]

@airsearescue What ratio are you going to use? i wouldnt have a clue what is needed.

[airsearescue]

@airsearescue good point I'll use good old t and e trial and error. If I can't hold on to it then I'll go for a less screw pitch or vice versa

[pawpawgator]

Nice...but how do you brake or slow down with out friction rubbing a hole in the tire? Otherwise, pretty cool!

[Reverseflush]

LOL, I had a self propelled lawn mower that had a mechanism set up like that on the wheel so there's no belt or chain. Too bad that destroys the tire but hey, tires are cheap anyways. Watch out it don't over heat that tire..POP))P

[geoff390]

@Reverseflush Yea iv seen a few like that.

[laxplayer1199]

@geoff390 in order for the tire not to pop, get a solid airless tire for like $15!

[06crjohnson]

how is the motor attached to the metal platform



[geoff390]

@06crjohnson with a hinge bolted on to the cross piece.

[geoff390]

@06crjohnson Oh umm i just made up some brakets and bolted them onto the engine and the platform.

[challengerdodge]

oh my chainsaw didnt have a reverse nut on it. Dumb design

[1029blaze]

dosnt that mess up the tire very quik

[geoff390]

@1029blaze the spindle in this video did but then i swaped for a splines spindle and a newer tyre and it lasted quite a while.

[gaspowerrules]

@geoff390 cool bike

[Rada194]

Does it overheat quickly ?

I made one and it will overheat in about 30 minutes

[geoff390]

@Rada194 mine never overheated well not to my knowledge. How did you know yours overheated?

[Rada194]

@geoff390 I would ride for about 30 minutes going full speed (about 27 mph ) and then while still holding the throttle it would start to slow down then after that would happen it felt like it was only idling (at this time i was going about 8 mph )and when you would press the throttle it would just bog the engine out. So i would let it sit for a couple hours. and try again and i would only get about 30 min of ride time until the whole process started over again.

[geoff390]

@Rada194 maybe try to richen the mixture or something.

[Rada194]

@geoff390 alright ill try that thanks

[lambymx69]

@Rada194

that is quite likely to be because it is overheating

[challengerdodge]

how did you lock the peg on so it doesnt come on?

[geoff390]

@challengerdodge I used the original reverse nut that held the clutch on.

[idrivesafe]

Hey everyone check my page... i made a chainsaw bike with a Homelite 240 + I built a real pipe for it !!!

[soggieshorts1]

good job is that a solid tube in the back tire?

[geoff390]

thanks, Its a inflatable tyre. this white one was a bit old and tired. when i put a new black one on it was much better.

[Lacrossanator1]

thanks for the reply but i have a metal lathe two and when you said it was roughend on a lath is it like heaps or ring indents or a "spiral" thanks again

[geoff390]

Ah ok having a lathe is a massive heap. I used the knurling tool to make the pattern, however it didnt grip that well. If you can find or make a splined shaft and drill it out they are much better.

[Lacrossanator1]

hi thinking of making 1 (probs wont b as good as this but...) wondering how many cc, where to get shakle thing that tentions spindle and lastly is the spindle smooth or rough and how did you make it rough ?A reply would be appreciatred :)

[geoff390]

Hi This motor is about 30cc chainsaw engine. (chainsaws are better because there more powerfull), The shakle could be got from any hardware store.

This spindle was rough and made on a lathe. People often use bike pegs.

[deltaforcehacks]

how fast it goes

[geoff390]

about 30-35 kmh

[chickenpoper]

how aout in mph?

[geoff390]

i dunno convert it you lazy fuck

[chickenpoper]

lol..what got into your pants you grouchy dumb fuck

[sk8er37dus]

wtf, you're arent funny, respect what that dude has done

[chickenpoper]

noooooo.....i liked the bike but he called me a lazy fuck just for asking how fast it went in mph....

[sk8er37dus]

but, it's easy to convert it, do it by yourself

[blizzard249]

i dont care about ut "custom exause pipe"

[sk8er37dus]

@blizzard249 i dont care of what you think

[blizzard249]

well good for you

[braaup]

It is about 20mph. And I don't see why he flipped out on you either.. I hope this helped! :)

[geoff390]

because its very simple to do and im sure its a good thing to know.

[chickenpoper]

@braaup thx he probably has angermanagement issues

[chubbyllama7]

ive seen alot of chainsaw bikes using that design so i think that would be the most effective build, cool bike

[madfighter56]

dude u shld have gone straight pipe its sick!

[Kim07445]

nice nice nice i want it tooo !!!!

[kris270fs]

your a moron

[ebarnes419]

cool fab!

[DawGy376]

how did you make it adjustable so you can adjust it with the turn buckle?

[VolkgartenBySquirrel]

I like your project bike, and it has given me a new idea about F/R gearing. But I have no idea where to tind a steel frame bike without unloading a lot of bucks! Good job!

[geoff390]

scrapyards should be good. or just find old things people have thrown out and salvage that metal.

The metal cross piece, mounts and exhaust were all scrap i found.

[Ethensyardsale]

Now that's cool!!

[LAtexStretch]

or you could buy a motorbike. Cheap ass.

[DawGy376]

or you could build one and not be a lazy fat ass like you

[kinghowie8]

OR we can all leave our bikes alone and stop being lazy and actually ride them!! lol

[geoff390]

Hehehe i did have to pedel occasionally if the hill was too steep

[kinghowie8]

lol

[DawGy376]

Or you can have a little fun and trick that shit out, and its not rly being lazy because you cant ride it any where unless its like under 50 CC I believe. which isn't a lot of power "to me."

[kinghowie8]

true

[kwackaboy]

Any idiot (like yourself) can go and buy one, the fun is in building it yourself. Top job Geoff390!!!

[xiteamxi]

if people had to ask witch way to ask for the spindle to spin they shouldn't attempt to build any thing and probably have no ability what so ever to even do so sad

[geoff390]

i do agree.

[dawangster]

what did you use for the spindle

[geoff390]

this was a knurled patter but in the end it is a sort of spline pattern

[kilvington11]

o i didnt know you did make a video of you riding well its cool

[kilvington11]

why not make a video of you riding it, it would be very cool

[unvise]

thats cool mate. fuck the retards who diss. i bet this was fun to make :)

[geoff390]

thanks bud.

Fun to make and ride!

[NAPALMJUNKY]

Good vid mate, great job on the bike. I made one as well but now i'm thinking about a chainsaw or lawnmower engine.

[cuevarap]

OK as an experiment but it's definitely not a bicycle. At this point one is leaving bike territory and taking a step towards motors. Why not purchase a small scooter, say a 50 cc.? They come with CVT (constant velocity automatic transmission), no clutching and shifting and very more silent than a chainsaw.

[cuevarap]

Would have been interesting to see how it works on a ride.

[coldshotjason]

well going forwards wouldnt be pointed to the back of the bike...lmao

[geoff390]

fuck up it was my first speaking video i was a bit nervous

[pabparkour]

0:46 ...fail

[geoff390]

pabparkour ... fail

[rick130]

thats a dumb idea cause all the rod is gonna do is slip on the tire cause it has no teeth or anything on the driveshaft.

[drummanutta]

custom?? u mean homemade

[geoff390]

its both

[swabbster3]

did you get partnership or why is there an add in this vidieo

[geoff390]

got a partnership but its not worth it so i dont put it on any more videos.

[MrFlintnSteel]

dude you used the exact same words as DavidsFarm did on the Motorized bike u copyer

[geoff390]

his bike is chain drive dumbshit. And i dont think i did. I cant be fucked to watch his video but could you please copy/paste what he said that i said the same?

I await your answer.

[MrFlintnSteel]

not the fuckin point dipshit U used the exact same words that he did in his vid dumbass

[geoff390]

Are you on the shabs mate?

[NJ43v3r]

chainsor haha. and wat do u mean u wil probibly go backwards? u wil definatly go backwards

[geoff390]

Haha thats ok.

[aznkid221]

Actually how you're making the tire spin is a good way because you wont wearing the tire out to fast

[geoff390]

yes a Chainsaw... I dont know what a redcoat is but im pretty sure im not one.

[vtecboi18]

its cause your british back in the 18th century wen america and the british were at war thats what we called the british redcoats, but don't take it the wrong way hes just trying to be funny i'm sure, nice bike by the way

[geoff390]

Well i guess you learn something new every day.

[haros540air]

pretty smart

[marripoke]

4 miles per second

[daftaddiction]

my uncle made one

it went fucking

fast

[marripoke]

i made this using a peg and a 120 cc mower engine and i goes 4 mps

[Benisasome]

how did u put the spindle on?

[VideoGamer945]

That's damn cool

[Tdogg161616]

Where did u learn to build it?

[geoff390]

Tzi scooterworld.

[fpyout]

ths is shit

[Marzocchirider6]

lol wow talk about jerry rig haha kewl tho!

[ArgleBargle1066]

Hats off for an original design...even if this "proto-type" is pretty ugly...at least it works. I'm sure a later version will be more refined.

[geoff390]

the new spindle with grooves gripped very well. Not too much pressre after a bit of riding you get to know how much.

Having grooves similar to a goped spindle is very good/

[AWulfekotte]

what is the piece called that you adjust the level of the spindle

[geoff390]

turnbuckle.

[sandokanSK]

hello, which is the tube and the engine?

[geoff390]

i dont quite understand what you mean?

[atourdeforce]

dude you seam capable so why dont u get a 50cc n a big bike take off pedals direct belt drive(A section prob b gud nuff) to pedal pully. ud prob need to gear down at least 2:1 mount engine under crossbar, and use the biks orignal gear change as is, and away you go u would easily get 70-80 mph before it tops out, although i doubt you would be able to get through half the gears before the engine becomes unable to cope with the ratios????

[wallyworldusa]

I'd like to see you going 80mph on a small bicycle. Maybe he doesn't want that much speed? Plus, you have no idea what you're talking about.

[atourdeforce]

whats with the agro, i said in the message "you wouldnt see me going 60 or 80 mph im not that brave",(if i didnt i say it i ment to im not bothered to check) but with a little inginuity and good design it would be possible,i was only giving freindly advice, hes made a slow bike maybe he might NOW want a fast bike, or a slow but powerful bike. secondly how do u know i dont no wot im talking bout, either way i dont care, think wot you please!! butt out i wasnt talking to you!!

[MrRadman3001]

how did u attach the thing that makes the tires spin

[geoff390]

using the original reverse nut that held the clutch on.

[MrRadman3001]

thanks man im startin my own but on a mountain bike

[wallyworldusa]

He's answered that question about a hundred times. Too bad people won't bother reading.

[h200022]

Ello Alex

[geoff390]

... i dont follow

[dhipender]

get a reduction gearbox ofr some used moped b centrifugal clutch assembly tht will help i to govern ur speed n drive

[joehorst92]

How and Where did you fasten the spindle to?

[geoff390]

I used the original reverse nut that held the clutch onto the engine.

[MrCrazynitro]

two strokes start up in any direction

[garagecrap]

That's what I thought, but when I tried it I wasn't able to get it started. Don't know why.

[geoff390]

the timing of the magneto would have been off

[geoff390]

Yea i have heard that but the magneto would be thrown off

[ladragonaperla1988]

bad, use a chain

[magemager0]

Really the best way is to use sprockets and a chain, the way demonstrated causes premature wear on the tire, and you have to replace the tire often if you ride the bike alot.

[geoff390]

with my new spindle i made and a black new tyre it lasted for quite a while, you would have been surprised

[magemager0]

Well you did use a smoother spindle, some other models have like a rougher surface that digs at the tread, btw i like the bike with the new paintjob

[Nk00037]

is changeing the tire hard lol

[geoff390]

not really

[mmcgartland]

solid rubber tires

[rawux1228]

i think better to use chain

[ONxTHExGAS]

your gona go backwards because the motor should be on the left side of the bike if it is spindl drive

[geoff390]

All depends on which way the motor spins.
