Over 40 years ago I made a 1cc motor drive a bicycle at about 30 km/h. It lasted less than a minute, but it was the success feeling I needed for myself 😊
As a former rc car enthusiast I was wondering how long that poor little clutch would last! I’m shocked it even worked the first time, I’ve burned them up in tall grass before! Still very cool!
I think you need to lower their gear ratio to, I had the same engine and I think it run better with the cone in the pipe closer to engine so that you don’t need to run it super lean for
Thanks for taking the time to make these videos 👍 I understand how much time it takes to make projects like this possible. Haha I have a CNC robot in my shop too, robots are awesome 😂
The Tomos clutch needs a serious weight reduction, it's engaging at a too low rpm. Four NovaRossi, Picco or OS engines would solve a lot of problems ;-)
he left the original Pico clutch on there, I think that was a Pico. yeah he's running two of them 😝 oh snap. I just watched the rest of the video. yeah you're absolutely right that thing is too much rotating mass for that big clutch to do the job. and the little clutch is going to cook.
@@fuhkoffandie With a bad setup those clutches can even cook on a 3,5kg buggy, lol, i'm surprised it held on for that long! I think it's an HPI 3,5cc engine btw.
You're SO right - a lot of us have dreamed about using old tiny nitro RC engines for bikes etc. If you're looking for a working clutch design for low-power engines, check out the old Honda CT 70 (and 50, and 90, and 110) "automatic" clutches. They're probably too heavy for this application, and they run in a light oil bath, but they're designed to operate reliably with 3.5-10 horsepower engines for years and years. I got a CT 70 when I was 12, beat it up for 4 years, gave it to my middle brother, who beat it up for another 4 years, then gave it to our youngest brother. He rode it until he turned 16 and got a Honda 200, traded it in and it was still on the original clutch plates.
Can you reduce the spring pressure on the main clutch? I had a batavus years ago and I was able to stretch the clutch spring and remove a couple of the steel balls to raise the stall up preventing it from engaging at lower rpm. Made takeoff from a dead stop much better. Higher revs allowed the clutch to really grab instead of slip. Similar concept as to some of the comments below for the RC clutch.
I would reduce the speed first with cogwheels and use a regular clutch from a moped. This ensures the engine can run in it's intended powerband and you will not smoke the clutch.... Love this channel!
that's why I love this guy. he's not afraid to try things that every gearhead, whether just a kid, or grown up, has wanted to know, or try, and couldn't for one reason or the other. that's awesome. I mean, who hasn't tinkered with these little motors on RC cars, and hasn't thought about doing this at least once? 😎👍💯
I ran 3.5 , 6.5 and 15 cc in the 80,s and it did go through my noggin what would they drive transport wise . Also had the cops ring the door bell after i fired up the 15cc at midnight , LOL
I'm impressed the RC motor and it clutch drove the bike at all, so in that way it was a success. A 15cc RC engine is more likely to have a fighting chance and perhaps a go cart chain would run smoother.
Your channel is quickly becoming my favorite experimental engine/motorsports/tinkering channel ever! Your ideas are everything I've always ever wanted the fabricate and experiment with! I wish I had the machines to do this stuff! Rock on!
Any tiny engine with sufficient power (~1 hp and up) can be used for powering a motorcycle. Depends on what top speed, acceleration, fuel consumption, noise, emissions, and service life you're looking for.
i was watching your videos for three years, although i have never ever riden any kind of moped or scooter in my life. let alone a two stroke... don't know why, but i was never intending to use any of info you provide so elegantly. and about two weeks ago i found an old riga-13 two stroke motorised bicycle in grandparents shed... i stood there for about ten years untouched, partly dismantled. No clutch cover, no ignition system cover. Just rusting. Today, i got it perfectly running and went for my first half hour ride around the block. Thank you for the inspiration. And the two stroke sound is just out of this worl :D
@@ruggugglan lol. Be cautious tho, they can run hot and become stuck pretty easy. I don't think your wife will appreciate having to push it home as I did in my teenager years more then once.
Just imagine hearing this thing coming screaming down the road from the direction of the shed that the worlds most powerful 2 stroke was made in. And you see this madman rolling past you at walking pace...
Ha ha ha... I know the feeling when you just know that somebody will get angry if you do something, but you can't help yourself.. Just had to do it.. Love it ;)
The failure of the RC clutch was disappointing, but expected. Could you just add stiffer springs to the current larger clutch to alter the engagement rpm?
I think you should try a bigger sprocket on the rear wheel. These engines need revs, as you said yourself. Cool video, I've always wonderes if this would be doable :) Cheers from Denmark
@@EUROBEAT.Volkskombi no. It's the opposite😊 Bigger on rear wheel, or even better smaller on the RC engine to get higher stall speed. Or bigger on the "crank"shaft.
Man and me struggling to fit 2 bearings in a minarelli moped, this man thinking of machining axials, bushings, and clutches for a minuscule toy engine.. You are crazy, never let the brap die!
I would reckon that you need a lot more reduction on that first stage so that the motor gets to spin up more. Instead of a chain and sprocket maybe a timed belt although at 16-25,000 rpm the centrifugal force may make keeping it on a problem. Since I first saw you show that little nitro rc engine on the channel I've dreamed of converting 1 (or more than 1) to run a chainsaw.
Thanks so much bro always wanted to try this now I know it will work!! Because if it works with a 3.5 cc Engine. Imagine what it will do with a 15cc rc engine!
For fine tuning the chain tension/overcoming the design flaw, you could simply use some jack bolts threaded into the top plate that when screwed down push off against the bottom plate.
You should definitely get should a 1/5 scale two-stroke RC engine they make them from 23cc up to 30.5cc as far as I know and I had a Rovan RC with a 30.5cc engine that ripped pretty hard! The components are tougher as well like the clutch and it's big enough so you can actually modify the cylinder and case for more power!
Thank you for trying this. I always thought it would be fun to try it on a bike with a 9 spd cassette to see if it could shift like an F1 car, but it needs more torque just to overcome the drivetrain friction. You have proven that the chain could be mounted directly from the motor without flying off, so I’m impressed. How about using a 2 stroke chainsaw motor?
That is a Tomos block your using and the clutch has a one way needle bearing in it, it locks in one direction and freewheels in the other direction, it locks to the crankshaft in one direction and freewheels in the other direction!
Nice attempt! I wonder if a bigger sprocket on the clutch would help. Also I think it would be interesting to see another one of these added for the front wheel.
What a machine! You, Sir, are a star of TH-cam, a true star.... I hope you live life and prosper.... Wishing you all the best from North Nottinghamshire UK
Based on my experience with the Vegas, next time you bring a different framerate video into the timeline -> right click the video, go to properties and at video event tab "disable resample". The file will render and play normally after that.
Fun stuff and now we all know too. Thanks! Maybe keep your eye's open for small boat engines with wrecked bottom ends. That would be a fun 2 stroke de-stressor project. Plus who wouldn't want to know if that would work? Prudes with stock engines, that's who! Cheers man.
Very cool, definitely thought about this a lot when I still drove my 3,5cc carson. Are there no adjustment screws on the clutch? Puch clutches had adjustment screws that would allow a somewhat-high grab point. If that wasn't enough there were stronger springs available.
Nicee work! What about a gear reduction? The nitro engines rev to around 30000 rpm idle bloody high too so the clutch cant bite because the engine would have to bog down to stall point. A gear reduction may allow you to reach a middle ground of top speed and torque.
It reminds me of one of my uncles, he's a medicine doctor, and he's playing around with old 50cc race mopeds the weekends. He made me try one once, I remember that stupid high revs sound going at around 10km/h before changing gears. Then I've been arrested by the police 😂 That's a funny thing though
First time you reved it I could tell its rich and not reving enough. I think your gear ratios need to be optimised for the engine to rev to about 30,000 revs. I recommend an LRP .32 engine with high quality 3 or 4 shoe clutch shoes.
Part of the title caught my attention, I didn't dream of this as a kid, bit I used to have a idea about riding a gas r/c car around and how cool that would be, near impossible but to a 10 year old it was possible
You have a CNC mill. Order a replacement crankshaft, turn and polish where it was obviously intended to have bearings, then modify the block to add cross bolted upper bearing supports and a new bottom plate with lower bearing supports that bolt into the upper bearings. With the right aluminum alloy it won't need any special coating or insert bearings. Many overhead camshafts run right on the aluminum head metal.
4 inline banger needs atleast 3 crank bearings, 5 would be better. I also would split the case/block where the bearings are, bolt together with 2 alignment pins and line bore for the crank. because tiny bearing caps are a nightmare
One option is to make the crank webs also serve as the journals for large diameter rolling element bearings. This way the crankcase can just be bored through with no split bearing caps, and the crankshaft inserted by sliding it in axially. This approach was notably used in Tiger tank engines during WW2, but isn't popular now because the surface speed of the bearings tends to be a bit high for plain bearings.
@@nerd1000ify I think oversized bearing to slide the crank in axial might just be the way to go on miniature engines. No worries about surface speed when the whole engine is tiny.
This is fantastic! When I was a kid, I always wondered if this was possible. The engine on my rc airplane looked similar enough to a motorcycle, but I couldn't test it when I was younger.
That frame the way it is made. you can use it to make a mold to make a Carbon kevlar frame. sheet metal to Composite. just a thought I like the shape of that frame.
That frame is an old NSU quickly , I had one in 1965, an old NSU Quickly two speed, I suped her up and got 45mph out of her!! My first "motor bike" and I loved her !! I rebuilt her from scrap parts, and boy did she go for a 50cc moped!! Good times !
Just pedal up to a respectable speed then engage the little thing. Even my 66cc takes a pedal or two. I think it would do great on a jackshaft and using index gears
If you want a clutch that engages at higher RPM, try a GT clutch, something like the Reds Tetra GT (MUAX0002). Though those only come with composite shoes so they'll likely burn up really quickly too. The Tetra Off Road with alu shoes (MUQU0066) on the hardest setting might work as well. The main thing though is that you'll likely need a much shorter gear ratio, the engine really didn't even get to rev at all in that test and I don't think letting a tiny clutch like that compensate for it by slipping until you're at the right speed would work out either. Though you have to keep in mind this is an incredibly cheap engine that definitely doesn't put out the 2.5HP it says on the box, idk how they can get away with such a blatant lie.
I have a Cen/Gen 7.7 and was actually considering the feasibility of this the other day. Thanks to your amazing video, I have decided to go on to another project, like, keeping the nitro engine in the model where it is now, getting a beer and chasing my cats with the remote 7.7. 16:10-An appropriately sized fan hub with thin, angled blades pressed onto the primary clutch body may allow the clutch body to shed heat in a more rapid manner than it does without a heat elimination strategy
You need a really high actuation clutch. For example, on my bike with a ktm sx 50 engine, the clutch is triggered at 9-10 thousand rpm. If it's softer, the bike won't move.
If you replace the first drive chain with a friction drive you could have better gear reduction since the smallest bike chain sprocket is relatively large. Or use #25 chain. Pocket bikes are available with a 5 tooth #25 chain sprocket.
That's cool, my kids pocket rocket at 39cc will hardly pull my weight from a standstill but with a bit of space to get up to power band things get real quick real fast

16:10-An appropriately sized fan hub with thin, angled blades pressed onto the primary clutch body
may allow the clutch body to shed heat in a more rapid manner than it does without a heat
elimination strategy
Tq fr sharing, Sounds like the F1 runs like a 3.5cc engine...it's fair enough

I didn’t think it had enough torque to make it happen. Awesome video though. I’ve always wondered if those little engines could do it.
Great engineering job bud!😎
You need a really high actuation clutch. For example, on my bike with a ktm sx 50 engine, the clutch is triggered at 9-10 thousand rpm. If it's softer, the bike won't move.
Was that the neighbours on the phone telling you all the places an 3.5 cc RC engine will fit at this time of the night:)
If you replace the first drive chain with a friction drive you could have better gear reduction since the smallest bike chain sprocket is relatively large. Or use #25 chain. Pocket bikes are available with a 5 tooth #25 chain sprocket.
I have never dreamed this.
YES I HAVE dreamed about doing this.... 😁
Now I don't HAVE to, because YOU have done it.... Thank you! Now I know... 😆
That's cool, my kids pocket rocket at 39cc will hardly pull my weight from a standstill but with a bit of space to get up to power band things get real quick real fast
16:23 Mrs Stuffing...shut you down !
Port that little cylinder😁
