Amazing Lawn Mower Motorized Bike (Part 2/2)
HTML-код
- Опубликовано: 21 сен 2024
- Well boys and gals we finished the lawn mower motorized bike. This motorbike functions using an angle drive to convert the vertical rotation of the lawn Mower engine into a horizontal output to drive the rear wheel. I took it off road and despite needing a new tail-bone it functioned very nicely, not quite a dirt bike but oh well. Anyway If you like this project be sure to check out the channel for more motorized bikes, dirt bikes, go karts, gas scooters, motorcycles, quads, atv's and a crap ton of other stuff!

The more you build, the more I get inspired to finally build something myself. Always wanted to do stuff like this as a kid, but either didnt have access to tools or lacked parental support.
do it! I was building dog poo when I first started, Still am!
Why don’t you use a small centrifugal clutch? It would simplify the build and your engine wouldn’t stall out all the time.
Because that's too logical. And I like belts drives n' stuff!
Yeahh what the guy said 🙄

David Wichner im Jet Tofte on AZ minibikers. We have talked a couple times. Nice
@@azoff-road1911 hahahah whats sup i didnt expect this 😅😆
Nice!! Find a way to add a heavyer flywheel and it will solve your stall/torque issue. In the lawnmower, the blade acts as a flywheel gathering inertia overcoming stall.
Yes. Also, a set of rings. But, a Briggs 3 hp will fit that fine. They are very heavy.
Well it also has a flywheel on top, which has the blower fins on it, and the magnets for the magneto.
"I look like a crazy..." while having a lawn mower bike frankenstein in the back, I think you do more than just look. Love the vids.

I got this vid 09/16/2020 as RUclips recommended. It's a masterpiece. Good to see that YT didn't recommend me way too late , just 3 days.
Cheers buddy! Thanks for watching
I appreciate your all your hard work and effort and engineering skills great job!
Back in 1968 I built my first motorbike with a horizontal shaft 4 horsepower engine . I used 12 inches of angle iron and 2 u bolts to bolt to the frame. Centrifical belt clutch and one wizard rear pulley on a 26in wheel.
No welder, no cutting the bicycle frame ,no high-tech tools just me in the 6th grade building a motorbike that went about 35 to 40 miles an hour.
Sometimes a simpler design is less complicated and less breakdowns.
That's great for a 6th grader! I was just a flashlight holder for my dad, didn't actually get to use any of the tools. Stuff didn't interest me till after I stopped talking to him. He made me feel disinterested in understanding or working on things bc it was never fun. Now I love building and watching stuff like this
@@Freebyrd1991 " after you stopped talking to him" ?
finally someone put an old briggs mower engine to good use
I use mine to cut grass 😂
I would put that same system in a go kart. If its and old enough one, you'll have a metal cam and not a plastic one, so you'd be able to put a little weld on it and make a ghetto performance cam. I learned that from Cars and Cameras on RUclips
My dad and I place a lawn mower engine on top of an old boat engine mid section and lower unit. Made a new drive shaft with a 9/16 universal socket for a u-joint. great running little motor wish I still had it and a few pictures.
Nice! That's what's cool about posting to youtube, It's just a time-capsule of all my projects
Stepping up your game with the tubing bender....
No doubt!
Yes! A plasma cutter table, & a tubing bender, plus a nicely laid out tool & compressor area, pure genious, money well spent. I loved the nice, clean gusset assembly under the engine. 2 suggestions, go back to the bigger belt driven pulley & find a carb with an idle adjustment you can open up to richen the transition from idle to midrange. That single speed carb just cannot handle the transition, it is simply to lean. Hack on a little carb from GoPowrrSports, like a mikuni clone. Get their suggestions. That very shaft has much fiber manners in it's future! Again, welcome back Sir 😎. Your quality of work has greatly improved & you're still entertaining, congrats!
Fix bad sentence: That vertical shaft engine has much finer manners in it's future
Thanks Paul for the suggestion! Sounds like I need a new carb and a flywheel
Cross country trip? Just add a fancy fuel tank backpack!
It would be neat to run two separate belt drives next to one another with two different pedals, that way you could have one geared more for speed and the other for off-road torque.
Your mower engine has an aluminum flywheel due to the blade being the centrifugal force for three of the four strokes. You need a cast iron flywheel from a horizontal shaft motor or make a weight to attach to the crank to take the place of the cast iron.
A spontaneous piece of motorized sculpture!
Lawnmowers have a blade that is mounted directly to their PTO this means they can be made with lighter flywheels. If you changed the flywheel out from one off of a pressure washer that was weighted it would probably function better.
Thanks for the tip
Awesome build, first time seeing a belt clutch on one of these, seems like a great idea and easier way to make a manual clutch than fabricating a whole transmission.
Glad you liked it!
It’s at least the second one he’s done! Dude where are you videos?!?
Try adding a torque converter or use the principal to make a manual ratio changer. Have it operated by your right foot. Use your left hand for brakes. Maybe fancy led lights all over it too!!! It’s kewl!!
You're a gifted mechanical genius!
Glad you're getting vendor support. You deserve it. Keep building your imagination.
Thanks man!
Haven't seen the first part yet? Check it out here --> ruclips.net/video/pSS5GUiuFvQ/видео.html
Your problem solving skills are impressive! Your new tools seem to be in a very good home.
That thing could use some rings, man. Also, take the head off, use a wire wheel to clean up the carbon for everything, put a new spark plug in it, and run it. You'll end up doing it anyway If you rebuild it. Trust me, you won't regret it. It wont die when you take off, either.
I'm sure it needs all those things, but also I agree with many other comments that the lack of a flywheel is what was causing it to stall so easily
@@OliverMotorized yes. I think I replied to someone's comment on that subject. I said that a flywheel off a Briggs and Stratton 2 hp or 3hp would work great. They are about twice as heavy.
Interesting build. The belt drive reminds me of a 40s gibson tractor. Please please fit a spark arrestor!
I like the foot pedal clutch
Hey man sweet build turned out real nice! Great to c them vertical shafts getting sum love. Cant wait for the next one! 👍🤘
Ha yeah don't see many youtube builds them huh!
I wouldn’t be able to let my nuts flap in the breeze just quite so close to that ramshackle jackshaft like that. You really could end up with a jacked shaft. Truly inventive work you did throughout this project. Now I’ve seen what’s required, I don’t think that I’ll be making any vehicles from the old lawnmower anytime soon!
I think you have bigger problems if your nuts are flapping that low. Just kidding! Thanks for watching !
Mr. Kim here and you sure are talented well you just keep going
It needs a clutch lol good job!!
Not criticizing, just a question.... Instead of that awkward foot pedal, why not just spring load the tensioner and use a hand lever to loosen the belt when pulled, like a motorcycle clutch? Awesome build!
Nice video. I like how you keep it realistic, and not to crazy. This is something most people could do in their garage. Keep up the good work 💪
I appreciate that!
Oliver I love your stuff, but when I saw part 1 of this video I expected you'd have problems due to mower engines having MUCH lighter flywheels (mower blade provides the inertia)
Looks like you do have a bit of a problem with getting rolling when you first let in the clutch (in the video where you say "not enough torque")
Might be able to get an iron flywheel from a vertical shaft Briggs pressure washer or similar.
You are right! The lack of a flywheel means there is less momentum to help sustain engine rotation while depressing the clutch. Hmm... maybe I'll rob one off a Briggs like you said.
Thanks for the insight Kurt!
@@OliverMotorized Told ya ;)
it also needs the heavy flywheel , from a pressure washer engine to maintain torque .
You picked the right engine if you wanted to show creativity and craftsmanship, but I most state the if you wanted practicality and simplicity going with horizontal shaft would had been the perfect choice. Nice 👌
Awesome build
Glad your back man. Not very much content like this on yt.
Like narration or stop and explain? Thanks for the feedback, Honestly!
Oliver Motorized I really enjoy the explaining what you are doing and giving us something to keep us listening. I don’t mind the montages but this vid had quite a few (don’t take me too seriously man) so glad you are back
Hillbilly Homeboy nah it’s ok I appreciate all the feedback I get. I kept this in mind with my latest video, so thank you.
This is the definition of a Lone rider riding his cool motorcycle like a badass.
ha Thanks bud
I love those food pedals. The mechanism looks cool. Nice
"It's an Oliver, from back in 2021". "Dang Pa, they sure knew how to make 'em".
Man, cool video... greetings from zimbabwe🇿🇼🇿🇼🇿🇼🇿🇼
Hey, thanks!
I love how you can afford a massive cnc plasma cutter- and you don't have welding gloves.
This thing is sick maybe you can put a riding lawn mower motor on 1 of the chopper bicycles next. I like how you got this running and wanna use this idea on a different size or mini bike to ride places.
you are so talented
There it is. Oliver is back. Great vids.
Listen brah you got the belt guard now how about some safety glasses?
You wear a mask while cutting and grinding but no eye protection.
There's very little flying around your shop softer than an eyeball.
5 to 10 bucks apiece at your home center... or mosey into your local eyeglass store and get 3 mm ANSI rated safety lens popped into some Buddy Holly looking frames.
A handsome guy like you can only look rad in those.
Your young, you have a long life ahead. Let's tey to get to the end with all parts intact.
40 years heavy construction here. Retired with both eyes, tho a bit deaf but with all my fingers and toes
On a vertical shaft engine designed for a lawn mower, the spinning blade acts as a flywheel so without it, there is little to no inertia built up untill the engine is at higher revs so this is why the bike keeps stalling when the belt is initially engaged.
Good one! There's More engines from lawnmowers with more power maybe you could try some more. Greetings!
I got an 8hp begging to be put on somethn lol
@@OliverMotorized amazing! I work as a mechanic of lawnmowers here in Chile, if you ever need some info or help, please write me mariojv95@gmail.com
It would be awesome!
Dude you have so much potential, and some awesome tools... it feels like your just messing about.
I enjoy the projects I do!
Yeah I get it, but I think you are capable of a lot more.... maybe in the future you can design your own bike.... 👍🏻 Take it easy buddy.
Your innovation is so amazing. Thanks for sharing.
flabergasted by a young man with such advaced skills
Your creativity always puts a smile on my face, thanks Oliver you are the man and as always "Howdy from Texas "!!
Cheers Greg, thanks for the continued support!
I see you have acquired and upgraded many new tools. Very nice.
sure did! thanks
I had one similar to your setup added another pulley to tighten the belt so when you pushed yours it would get even tighter
i did a similar build on a childrens bike, over the rear wheel.
was much easier to convert the engine to horizontal shaft
Thank you very much Oliver! Well done.
Keep it up and I wish you health.
Sincerely,
Alicia
Thank you Alicia!
Ty for posting again man. Now in this time of age youtubers make bank and you have awesome content. Can't wait to see them subs climb like craY
I wouldn’t do a predator 212cc horizontal shaft I would imagine it would’ve been way easier if f a build and maybe better performance as well but it’s pretty cool to see a bike that’s ran by a vertical shaft
yeah I've made plenty of bikes with predators, just doing something outa-the-box. Thanks.
All those sweet tools and you don't have a roller chain breaker? Nice job, very creative design.
haha my old one broke
@@OliverMotorized ha you broke the breaker. Sorry I had to. Nice bender too, I hope to get one soon.
Need a snowmobile clutch set up on rear pulley..or check out Rzr motor. Nice welding !
Thanks for the tip!
I haven't watched in awhile, lots of great new shop tools.
Welcome back!
That bike is awesome 👍.
A few mor gussets at the head and around the seat tube wouldn't hurt. Fantastic engineering with that vertical shaft motor. It has to be a first. 🏆
Cheers! thanks for the comment. I think you're right about the gussets
Oliver Motorized - Yeah, lotsa stress on that frame.
The most complex bike drivetrain.
I noticed you like doing things the hard way. Or is it spend as little as possible? Your fun to watch for sure.
ha a little of both I suppose, Thanks!
Nice build !
Thanks!
You win the mechanical look award :) I think it weighs as much as my Harley too ;)
this is what all my neighbors think my mini bikes are "is that a bike with a lawn mower engine" they ask. ill show them this video to clarify
Yeah with other projects I’d have to clarify where the engine actually came from such as a rototiller
@@OliverMotorized is great watching your videos again
That was a nice build. You got skills! Enjoyed the show.
Fantastic little build! What is the “junkyard piece” you mentioned in the last video that made the vertical shaft engine usable for this application????
You’re like my spirit brother! Lol. I do the same goofy stuff! If you haven’t figured it out yet, the vert Briggs has an aluminum lightweight flywheel that doesn’t do well without the weight of a rotating mower blade. This is likely contributing to the stalling. The iron flywheel from literally any 2hp to 4hp horizontal Briggs will fit right in without any changes and will solve much of your issues. Keep doing what you’re doing!
Yup many have mentioned the flywheel issue, Thanks for the info though!
Thanks again for the shout out on the last video! I will give you a shout out on my next video 👍 Man you are a master on CAD! Nicely done 🙂 I was going to recommend the Rogue Fab bender but you beat me to it.
Ps I would like to talk sometime, let me know when you get this message and I will post back my e mail, after you get it I will edit out my e mail so I don’t get spammed 😂
The pleasure was mine, I watched your channel a lot while I was gone. Hence the new tools haha!
And sounds good, looking forward to it.
Unless you just love hacking stuff together not compatible forced to afro engineering extra sprockets belts and pulleys ...we used to get a whizzer motor and bicycle kit and bolt on a two stroke whizzer engine in a few hours and go like hell
Would you have preferred I just buy and filmed me assembling a kit?
donnie baker I think you are missing the point of his videos, it’s not always about taking the path of least resistance and taking the easy route. It’s about challenging yourself to try different things, can it be done?
When building projects like this, it tends to make you a better engineer at the end of the day because you learn a lot more then just following instructions and bolting on a engine kit.
@@OliverMotorized yes as two day there are Chinese knock offs of the whizzer for like $59 bucks , just seen one for the first time the other day that looks just like the old whizzer engines .....but there is even a better way to do it your way by using a horizontal crankshaft engine ..like a 3 1/2 HP brigs from a walk behind garden rota-tiller..you can get new one from harbor freight cheap ..whizzer drives the back wheel with a large diameter belt pulley that looks like a thin bicycle rim fastened
To the spokes with washers and metal screes ..use a centrifugal clutch from a go-kart with a pulley instead of a sprocket and drive your bicycle with a belt that's it that's all you need
What type of welding is that? Looks incredibly useful and fairly easy
Respect from Portland oregon. Keep the projects coming.
👌🇺🇲👌🇺🇲👌
Thanks Jimmy!
Nice job! I love those Briggs engines.
I liked before I even saw the episode, love ya man, and as always you know "Howdy from Texas "!!
Right on! Thanks Greg!
Wow very nice coming up on some nice tools for the shop great build.
For sure!
finally a use for a vertical shaft engine. misty hell i thought it was that B&S engine just smoking. Now what is your next project going to be?Wish I had your talent. thanks.
I tipped the engine over a few times when measuring so oil musta got in the cylinder haha
Get a 3.5 hp briggs horizonal shaft flywheel from an yard edger or just order a new one, you'll find it's way much heavier than the one on lawnmower 3.5s. That's all it is. Great job man.
Nice army tan tee :)
I love this. If you made it so that the pedal increased the throttle as you push on it, it would almost be like a vct system
Hey good afternoon, congratulations on the awesome engineering behind your project. The innovation involved in this old-style bike is quite astounding :)
Be advised that your vertical shaft engine probably has no ball bearings... you could add a 6205 bearing or similar to the mounting flange if you want to :)
Also the clutch setup is not ideal for a single cylinder engine. In case you want to improve the take-off behavior, you need to increase flywheel mass. So the engine doesn't cut out that easily when the clutch is engaged. Greetings and good tinkering.
The smoke out here is insane where I live as well! Stay safe, make sure you/ your family has a plan!
Thank you, you too!
I have a Molkt 26mm flat slide carb from Amazon. $30. In my vertical shaft motorcycle and it makes a massive performance difference.
hmm I may have to upgrade
hi dont no if you will get this comment, but put on 2 belt teninesion er's , smaller at the frount and larger at the back. or just smaller at the frount. i did that with mine but i have a VANGUARD 22 HP i havent got to top gear yet
Very interesting, love how mechanical it is. Nice work
festive sent me. this is all fun!
Wow omg that is sooo cool wooow
Got the nice plasma table and tubing bender, but still break your chains the old skool way? Great builds though, glad to see your back at it. Be safe over there.
ha! I had a chain break, but the damn thing broke after 2 attempts.
@@OliverMotorized oh that sucks
Hey I don't know if you still have this, but I see you stalled it a lot. Don't be afraid to give the engine all the RPM. There's a video on my channel called "Wall Mounted Lawn Mower Engine" where I generally just rev one of these engines. Mine had the cast iron flywheel is the only change. I revved it many times and it's generally still fine. Well, it was, but I scrapped it because I don't really need a lawn mower engine mounted to my wall
Good Lord! That's ALOT of fabrication to adapt a vertical shaft engine!-John in Texas
Probably spent more on the fabrication and pulley system then just buying a cheap harbor freight horizontal shaft that would have had him riding in style.
yeah I've done that before, This bike was mostly just to challenge myself in a different way!
I watched part one last night and I was hoping you would drop part to soon glad to see you back with another awesome 1 of a kind build keep up the awesome work and thanks for your service
haha good timing! thank you for watching
why don't you just make 2 or 3 belt teninisors. side by side legthen the top sharft to fit another bigger pulley in order of coarse. and alter the lower one's size also.i have done this to my mini bike works well. great viedo
You did a great job.I like the 3D printer you have.
Thanks Sam, it comes in handy!
Hey Oliver,
Would love to see your girl do an unedited normal speed video on multiple bikes to show how many pulls it takes a female to get them started and running when the engine is cold too her touch
Great to see you back, Oliver! It looks like you are really stepping up to the next level with CAD, plasma table, and the tubing bender. Can you do a video of your shop and all the cool stuff you have in it tool-wise? I am particularly interested in that tubing bender.
Maybe sometime in the future I'll do a shop overview! In the meantime, the tubing bender is a Rogue Fab -- lots of you tubers have done reviews I'm sure a quick search will turn up a bunch lol. Thanks!
OLIVER YOU'RE BACKKKK
Yessir!
@@OliverMotorized welcome back keep up the awesome content, keep making weird stuff it's great🤣
Is the chain using a tensioner, how does gravity not win this battle?
Ever thought about using a automatic clutch?
Has a plasma cutter and a 3D printer.
Does not have a $15 chain cool.
Where did you get the right angle drive? Also, I wholeheartedly approve of the Saturn Ion.
haha, i'll get one sooner or later. I got the angle drive from the scrap yard.
Question : Since usually a mower engine uses the blade as a flywheel and without it the engine won't even start, what did you do to fix it ? ...simply the inertia of 90 deg. gearbox is enough ?
If you add a small flywheel to the out put shaft, it might help on the take off
Could have made the right side footrest an accelerator pedal alongside the handlebar one. One for getting going the other for cruising!
But either way, awesome build!!
Cleanest project so far, really like it good job
Appreciate it!
