Check out a similar vintage bike I did but with an old Briggs: kzfaq.info/get/bejne/qrqTf6aFyc3GfmQ.html&ab_channel=OliverMotorized

Just man, I miss this... thanks for creating

I've watched a couple of your videos and i can surely say. Its a shame your videos aren't more popular, you're on some million subscriber type of videos, i honestly hope you get the attention you deserve on this platform. Cheers.

I did this sort of thing in the early /mid 70s using chainsaw engines, I learned about tuned expansion chamber two stroke exhaust systems, and my high school shop teacher Mr. Vanspange, helped me make several tuned pipes with amazing results,

I look forward to seeing some refined versions of this and last couple builds. Keep up the great work.

Man this is great ! I Realy enjoyed the way you built and filmed this bike !

If you manage to somehow retrofit an exhaust pipe from a moped you'd get a more interesting power curve out of the engine. Look up the theory behind expansion chambers for 2 stroke engines, it's all about fluid dynamics, pressure waves going back and forth to both pull air/fuel mixture through the carburetor into the engine as well as pushing back air/fuel from the exhaust pipe into the engine. Along with a larger pulley you'd get a pretty nutty motorized bicycle!

I enjoyed the video. Thanks for sharing it brother. Such a fun hobby.

I like it (it looks so vintage) 👍

There goes Oliver on his dang motorized contraption of the week! Neighbors statement as he flies by.

Nice work Oliver! I always really enjoy your videos 👍 Me and my Son definitely enjoyed this project. Thanks for posting!!!

Thanks for serving bro., Respect! Glad you are doing ok & still have your creative juices (& humor😂) still flowing. Love the plasma table & finger break! I want my own (& a lathe & milling machine while I'm dreaming, right 🙂?) God Bless you Sir !

I'm so happy you are back...we miss you when you dont post videos..I've been a subscriber and a fan of yours for several years....5 or 6 years....thanks for this build....it's awesome.

Absolutely amazing! Thank you so much Oliver and I wish a very happy Christmas! Sincerely, Alicia from Sweden

Nice! Perfect! I wanted one like this to go to college and work.

I have several wrecked bikes and several lawnmowers and i am itching to make something like what you make. Colour me inspired, Sir. Excellent channel.

Glad you are back. Merry Christmas.

you build some funny bikes. I'm sure your neighbors love you...

Great project. Love it.

safety is over rated leave it be. good to hear from you again. happy holidays.

Excellent video

This was an awesome build, and use of an old bike and old chainsaw. I thought it a cool style choice to leave the bucking bar attached. Lol. Also enjoyed the innuendo comedy along the way. 👍🏼

Pretty cool. I realy love the old homelite sxl.

Amazing ❤

wow, this is very cool! I have a 99 Zuma BWS to rebuild and a statton inc kit to build! This is cool.

I like ur video and ur little shop u got going.The bike came out cool., looks fun.😊

its always a good day when oliver posts

Hello great projekt😊😊😊

I love the blooper’s dangerous but funny 😆, keep up the good work 💪🏾💪🏾🙏🏾🫡

Love the new videos!

I love your videos i was really excited when i saw you uploaded keep up the good work

Have you heard of the Solex? This was a very popular vehicle in the 1960s up till the 1980s, it had a front wheel mounted motor. if you ran out of gas you could pedal to a gas station. it was absolutely an incredible little vehicle

Good job

I bought a defective bag type 1kw generator. When I realized that the electricity-producing part was faulty and the engine part worked with a little cleaning, I mounted it on the back of a 26-inch medium-sized bicycle. I replaced the rear wheel with a 16 inch wheel to increase torque. and I bought a pulley the same size as the rim and attached this pulley to the rim. Now it takes me up hills with ease (I weigh 70 kilos).

Amazing!

You're Alive 😁👍

You put 'Fun' in disfunctional ;) That looked scary fast so I'd gear it down too.Merry Christmas Oliver and family, plus all the other fans .

amazing that the chain saw still works more then 5 years past the manufacturer date, used a lot? but that 4 bolt wheel sprocket adapter looks like it could be a very high demand item.

Neighbors mower gonna start right up and run great 😃😅

So sick brooooooo holy yoooooo

This was awesome, that chainsaw sounds so damn cool!

That is incredible. With a pre-packaged engine and mounts I'm still nervous going over 35 MPH.

Fun project

Wow

Awesome!

the exhaust on chainsaws are tuned to keep temps down and not start fires, 2 strokes do like backpressure tho

Remember when you messed with the snowmobile exhaust, then it ran badly, I think you'll find that with this wee chainsaw. On the flip side, nows a good time to learn 2 stroke exhaust design .

Nice !!

Cool I just bought a 43cc 2 stroke friction drive kit and a dual disc mountain bike for a new project

That aeesome

Interesting build, thanks for sharing! Also no opinion on the spring setup on the clutch. I can’t think of advantages and disadvantages of either way. Why no link to the Briggs build? I guess I’ll go hunt for it and stumble upon other videos while searching 🧐

Awesome, i like the fact that you have to petal it up to speed before you fully engage the saw!

Cool channel

You could bump start it by pedaling and then popping the clutch!

For some reason youtube did that thing where it unsubscribes me for no reason, just subbed again

sure you can add more power with a bigger intake only !

Farout!

You should make a chainsaw bike that doesnt sacrifice the saw, so you can ride to the woods and cut wood.

I think you should post more videos. Happy holiday!

awesome build bro!! love your channel please stick around!

youre so funny 😁

I think if you shorten the muffler up and possibly lean down the carbraider a little bit & fixed that gear ratio. That thing will move pretty good. Those old homelights don't rev like the new chainsaws do

Did a great job from my point of view. Did u adjust the pulley ratio? And do u think a weed eater motor could have enough torque to use?

I absolutely hate those dang cheap Homelites. But in this case, I have two of those sitting under a bench that I will eventually use for something. I can't remember if they got condensors & points or not. Old ones do. New ones don't. On the exhausts...they do say it supposedly has a purpose on scavenging, but in reality...you are not going to gain a lot from changing anything up. Though to be fair, losing or gaining 1 whole CC from a 25 to 50CC motor does kind of make a difference, and it comes down to backpressure/delay. Basically, it is as follows- usually, saws and such are not exactly "high performance" and nobody cares on the exhaust...it just has to be cheap and work. The form factor of a limb saw does not lend itself to a giant exhaust pipe. Nobody wants a 30CC limb saw with a 16" bar & chain, and a 24" tuned exhaust pipe to cut down a couple trees once a year. Now onto the rest... "...expansion chambers are built to harness sound waves (created in the combustion process) to first suck the cylinder clean of spent gasses--and in the process, drawing fresh air/gas mixture (known as 'charge') into the chamber itself--and then stuff all the charge back into the cylinder, filling it to greater pressures than could be achieved by simply venting the exhaust port into the open atmosphere." You will get lots of claims on the "super powers" of a "tuned exhaust" adding "massive increase!". It's up to you to decide if you want to put the work in on it, Oliver. It's a 2 stroke. The simplest motor in existence. If it's clutching design questions...it's A) whatever works B) whatever you like personally and C) whatever is easily repairable with what you got on hand. If you like it auto-engaging after cam/spring-action, that's fine as long as you always remember it does, and there is going to be at least one time you don't remember that. Going the other way with it just means the same output. The super ancient french bicycles from the early 1900's had all kinds of handles and levers, so...there isn't exactly a "wrong way" of "motor runs wheels turn I go forward in motion". If you get into the old engineering manuals from the late 1800's, you can come across tons of "clutching" or "power transmission" designs, including belt torque converters. "The Engineer's Sketch-Book of Mechanical Movements, Devices, Appliances, Contrivances and Details (employed in the design and construction of machinery for every purpose)" by Tom Barber, 1923 Section 88- Variable Motion and Variable Power ...by spur gear, bevel gear, cam gear, belt gear, belt cones, stepped cone, variable throw crank pin, beam motion, pressure accumulator, Wright's gear, Olmsted friction cone, convex and concave cones...etc. It's got lots of pictures, and every type of clutch design imaginable (along with chains & belts). Personally, I am poking around on manual clutching for 8" and above drive pulleys running belts for racing mowers...I just hate the old style "shove handle engage" or "let foot clutch pop up engage", when you can run with variable face electric friction clutching, or just variable face (smooth) plate-on-plate clutching (at least experimentally on small sized motors like a Briggs). I always like your vids, Oliver. Keep at it. Ain't no wrong way to do it. Just your way of doing it. That's how we ended up with motors & clutches as it is.

Man just come to Illinois and mount my 100cc engine on my trike🤦🏾‍♂️I’ve been trying since December to go from my electric motor to a gas engine and I did take the route of getting an engine that robs me of my storage basket, it’s just giving me an headache

Another great one - keep 'em coming. Looking past the climate change hoo-ha, micro-motoring saves our world from vehicles weighing more than than their occupants, not to mention how we're tearing into the planet for rare earth... to run our electrics. Motorized bicycles are the future - they're extremely low cost, a bicycle of any kind will force exercise at some point, even if minimal. A breakdown is never too serious with pedal power, and the speeds involved make a safer situation for all - especially if the little buggers are noisy. ...go LOUD and PROUD!!!

Hey so i havent given it a try yet but i got a Yeswelder 135. Read online that its better than the harbor freight 120 plus it has a stick welder function

best chainsaws to use for these are STIHL. for the most part, nearly every single one of them has a crankcase that is completely separate to the oil tank, fuel tank, etc. nice solid mounting lugs that are easy to use, and require no cutting or fooling around with removing excess casting... of course, once that pullstart is removed, you cant run the centrifugal clutch anymore, unless you give it a pulley and some rope to wind around it... i have found a few no-name brands that also have these separate and handy crankcase designs, but for the most part... most chainsaws are really unusable. when it comes to reliable, brand name manufacturers, stihl stands above the rest for this particular feature. besides the fact that stihl makes the best chainsaws of all...

You are my mentor that my I add motorized to my KZfaq name 😊😊😊😊

Did you just use what you had to determine the gear ratio?

Please fully grind and clean the metal before welding.

Is that a Worksman Newsgirl bike?

Did you consider a friction drive in this design

Regarding the belt tension clutch: you want things to fail and become safe. The sprung should disengage. Lil homie really welded heat treated tool steel to mild steel.... Lil bro needs to learn basic metallurgy.

Weld a pulley on to the centrifical clutch

U tryin to send a fellow motorized bicycle ride a chain break I need one lol and I'm broke

Where can you year codes at

call me a turbine because I am a big fan

I would of used a chainsaw clutch of a centrical clutch on it

Looks like the belt is too loose

Clean your metal bud, that's why your welds are all goobered...

Since this is a 2 stroke engine, you need to have a proper exhaust. A Proper exhaust for a 2 stroke engine is a resonator. When you have the correct exhaust dimensions it will increase your hourse power noticeably. 2 stroke + straight pipe = dog shit. I'm sorry but that's just the reality.

3:55 😃

Saw exhausts aren't tuned, it needs cones to be tuned, you could make a tuned exhaust and probably double the power.
