- 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 🙄

@@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.

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 CZcams
Stepping up your game with the tubing bender....
No doubt!
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" ?
Cross country trip? Just add a fancy fuel tank backpack!
I got this vid 09/16/2020 as CZcams 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
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 innovation is so amazing. Thanks for sharing.
"It's an Oliver, from back in 2021". "Dang Pa, they sure knew how to make 'em".
A spontaneous piece of motorized sculpture!
You're a gifted mechanical genius!
Very interesting, love how mechanical it is. Nice work
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.
Nice job! I love those Briggs engines.
Your problem solving skills are impressive! Your new tools seem to be in a very good home.
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?!?
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
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!
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
Thinking out of the box! Awesome.
That's the idea!
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
Interesting build. The belt drive reminds me of a 40s gibson tractor. Please please fit a spark arrestor!
I love those food pedals. The mechanism looks cool. Nice
That was a nice build. You got skills! Enjoyed the show.
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!
Awesome build
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!
love the videos, glad you started making them again
Glad to hear it!
Just glad to see you back love the engineer keep it up
Thanks Dean!
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
Fantastic little build! What is the “junkyard piece” you mentioned in the last video that made the vertical shaft engine usable for this application????
Awesome!! I love it!!
Very cool project! Excellent work
Thank you for watching!
I haven't watched in awhile, lots of great new shop tools.
Welcome back!
Wow very nice coming up on some nice tools for the shop great build.
For sure!
Thank you very much Oliver! Well done.
Keep it up and I wish you health.
Sincerely,
Alicia
Thank you Alicia!
It needs a clutch lol good job!!
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!
Cleanest project so far, really like it good job
Appreciate it!
Glad you're getting vendor support. You deserve it. Keep building your imagination.
Thanks man!
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 had one similar to your setup added another pulley to tighten the belt so when you pushed yours it would get even tighter
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
Be safe man, I’m in northern Oregon and the smokes been bad. Love the builds and one day would love to ride man!
Haven't seen the first part yet? Check it out here --> czcams.com/video/pSS5GUiuFvQ/video.html
Great video and I love how you designed the engine bracket. Very fast and efficent! Also i see new equipment? The shop looks great!!
Thanks! lots of new equipment!
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 !
CZcams recommended this. Glad it did! Nice build! 👍 For taking some junker parts and throwing them together, it came out really well! Taking pictures and slapping them into fusion 360 definitely helps. It's my go to method. If you have a ruler in the picture, you can also "calibrate" (scale) the picture to that ruler and then just draw up what you want and it'll be to the correct scale. Just make sure the camera perpendicular to the surface. Got yourself another subscriber! 😎
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!!
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 ;)
I liked before I even saw the episode, love ya man, and as always you know "Howdy from Texas "!!
Right on! Thanks Greg!
you are so talented
I see you have acquired and upgraded many new tools. Very nice.
sure did! thanks
Respect from Portland oregon. Keep the projects coming.
👌🇺🇲👌🇺🇲👌
Thanks Jimmy!
Nice build !
Thanks!
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 ?
festive sent me. this is all fun!
I like the foot pedal clutch
You're back!!
I'm back!
What did you use to change the crankshaft power from vertical to horizontal? Like what thing did you use to change the crankshaft to go the right way? I’m looking for one
You did a great job.I like the 3D printer you have.
Thanks Sam, it comes in handy!
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.
Mr. Kim here and you sure are talented well you just keep going
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
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.
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.
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.
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
How did he balance the motor with out the blade
Hey do you ever have issues with tires because of the extra load? I’m looking to build a motor bike using a riding mower engine and wanted to know if stock rims and tires would hold up, thank you for reading.
Hi Jacob, I’ve had issues with other bikes where the spokes pop out and the axle bent but that was with a 125cc dirt bike engine so it had a lot of torque compared to this bike. But if you are using a riding mower engine I would say you would want beefier wheels and axles for sure.
it also needs the heavy flywheel , from a pressure washer engine to maintain torque .
What type of welding is that? Looks incredibly useful and fairly easy
This is the definition of a Lone rider riding his cool motorcycle like a badass.
ha Thanks bud
You win the mechanical look award :) I think it weighs as much as my Harley too ;)
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.
Your builds are always unique and interesting. Glad to see you back to full fill my boring life 😂 .
Thanks Nick!
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
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.
What is that transfer case you're using. That changes it from horizontal shift to vertical shaft?
Is that from a trolling motor?
Love the vids
thanks!
Man, cool video... greetings from zimbabwe🇿🇼🇿🇼🇿🇼🇿🇼
Hey, thanks!
did you test its top speed yet
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!
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 army tan tee :)
If you add a small flywheel to the out put shaft, it might help on the take off
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 👌
Have you removed the governor from the motor?
how fast does it go?
That's a pretty kewl set-up.I thought,'Don't all frames start out as pipe dreams'?(went there)
har har my friend
Need a snowmobile clutch set up on rear pulley..or check out Rzr motor. Nice welding !
Thanks for the tip!
The vertical to horizontal gear you have. Did it come off some particular pics of equipment at junk yard? Im in need of one but not sure where to start looking at scrap yard.
Sorry I wish I explained it more in the video, because a lot of folks have asked about it! Unfortunately, I didn't see what it came off of. There was literally a bucket full of them though so I grabbed one.
Oliver Motorized you are lucky. I may have to go to my junk yard and just start looking around
you need a cast iron flywheel on that engine.it will never run right with that aluminum one on there.
what amount of drive reduction does it have. just guestimating it looks about 15:1?
off the top of my head it's probably about 9:1, With the pulley I swapped out, it was probably closer to 15:1.
Is the chain using a tensioner, how does gravity not win this battle?
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
So what is that part called that changes the rotation of the shaft or whatever lol
Idk I just been calling it an angle drive haha! maybe a right-angle drive.
@@OliverMotorized I hear yah lol, we are about to swap out an 810cc 30hp Briggs motor and I thought it'd be cool to put it on an ATV frame or something but wasn't sure how the transmission would work. Still undecided on trying it but I thought it'd be cool.
