- เผยแพร่เมื่อ 1 ธ.ค. 2017
- This video show you my NEW Motorized Bicycle. This second build is a much more detailed than my first build.
I paid $89.99 on eBay for this engine.
My previous kit got around 75mpg and averaged 26-28mph

You're video is one of the best I've seen thank you! Doing a buddy at works bike, and the motor mount idea was just what I needed. I'm a welder and was going to make a custom mount, but this saved time!
I am a mechanic and I wanted to add that I ALWAYS use hose clamps. Imagine riding down the road and something snags on your fuel line. With the hose clamps you are that much less likely to be covered in gas
Thanks for the good quality video 👌🏼
1,000% the best video on this topic and helped me finish up my project!!
Couple helpful tips..
When putting on the rear sprocket on use a "torque wrench" so its definitely then in the centre and straight ..
For better performance and reliability should used a better exhaust and air filter,spark plug,chain tensioner,(upgrade to the spring mounted one) (bc the stock one does become lose and goes into the wheel),then should be alot better build 👍
P,
You said at the beginning that you would have preferred a black painted engine. If the one you have is not painted, in other words there is no silver "coating" on the head and cylinder the engine will shed heat easier and run a lot cooler. If possible, I would always prefer raw metal on the engine instead of some kind of coating. Even chrome will tend to hold heat. Aluminum is a very efficient heat exchange metal, and is used in electronics for that purpose.
Thumb up! one of the best elaborated video on TH-cam. There's nowhere else that is better then this video.
Very thorough and straight to the point. Thanks for not going on wild tangents of thought and losing focus. Most people I watch can't stay on the subject.great vid
I think this is the best video I've seen of installing these bicycle engines. Very detailed. I'm thinking of building one myself. Thanks for the video!
The Rubber disc that sandwich the spokes are actually not made from old tires, they are made from Scrap Conveyor Belt. Like the conveyors in rock quarry's that carry rock. You can tell from the "plys" in the belting.
It's the same material used in "rag joints" on steering columns. Called a rag joint because you can see the fibers around the cut edges. Rag joints make a simple "universal joint" without bearings. This is very tough stuff. Sandwiching spokes in it to attach a sprocket is a clever adaptation.
Old style bias ply tires still have this construction
Agree
It's not a scrap anything. It is a brand new sourced flexible joint.
wow...thats crazy , thanks
This video is helpful I installed a 4 stroke the other week on a beach cruiser.. for my next act a 2 stroke silver angle crammed into a 1960s sturmey archer
Great video. I just bought a kit today, EXTRAS...I ordered a heavy duty chain, a dual brake lever, some Loctite and a spring loaded chain adjuster. I would only use ethanol free gas and synthetic 2 stroke oil. On somebody else's video they recommend pouring oil down the spark plug to pre- lube the cylinder. Let it sit and then turn it upside down to drain out. I haven't got any of the parts yet...... but that is my recommendation after watching tons of videos on the subject. GOOD LUCK WITH YOUR BUILDS!!
Best video I have found for building my own motorized bike. Thanks
Thank you very much ! Great detailed step by step how to video! 👍💯
My best friend and I built one over the summer last year. We ran into a few problems. We haven't done much to the bike just yet due to the cold weather. Hopefully tomorrow if the weather improves and it gets warmer we will finish the project and hope to get it going on the road
Tip buying a bike from walmart and other bigbox stores check the grease I always grease a new bike so it rides better well greased
it rides better well greased - thats what she said
10/10 video love the bike builds this one was way more descriptive then the first good job.
Very informative! I am looking forward to building out my Huffy!
thanks Steve , this is the best video about 80 cc . very good tips and detail information .
Very nice work on bikes and videos.
All in all, a pretty good video and a nice simple build.
Oh, great vid. Thanks for the info.
Another great video thank you I am building one now but I had to stop because it is so very cold in my garage.
.
Thank you for the vid. I'm still in the research phase, learning about all this... I haven't actually purchased or built anything yet. But, I wanted to comment about the "break in phase". Reading all these comments it hit, how & why it works. Ever "season" a frying pan? It involves taking a new pan, and heating it up with fresh oil in it. The heat causes the pores of the pan to expand, letting oil down inside. It also causes the oil to "carmelize", solidifying into a coating very much like a hard plastic. Obviously, something very similar happens inside the engine during break in. I've read a few people pooh-pooh'ing the break in phase, saying it's really not needed. I don't believe it.
It's the same reason why cars, motorcycles, and scooters all have a break-in. The break-in period is more about properly wearing the piston (thing that pushes the gas to compress) and the cylinder (the thing the piston slides up and down in) so that they are worn "together" (so that their grooves/wear patterns match). This is important because during this time you tend to have fine metal shavings (that wear off both parts of both as they are first used). The better you wear your parts together (don't stress them too much, don't use them in low-load situations, don't run them super lean w/out oil) the better fit you get. And the better fit you get between the piston and the cylinder the more horsepower you get. More horsepower means, well, more power.
Thank you so much!!!! So detailed.
I enjoyed the whole video. Got some good tips that made my build an easy one time through assembly thank you. Nice job.
How cän I a engine like that let me ķnow
I wrap the hub with masking tape until the sprocket slides over snuggling and it centers the sprocket perfectly.
I love the spring seats on those classic bikes
Wow this was immensely helpful ! Thanks
Great informative, step by step video.
You should really consider getting the tektro beach Cruiser brakes, they work on the beach cruisers and have served me well. Wider brake pads with more contact area to the rim also make a difference to an extent
The wider the pad, the less pressure they have on the rim.
@@thra5herxb12s You should probably contact F-1, Ducati, Yamaha, Suzuki, Kawi, Honda, Bugatti, Chevy/Corvette and any other builders of high performance, wheeled vehicles, to let them "know" that they can now reduce the swept area of their braking systems, shrink down their ever-larger rotor diameters, quit building 4, 6 and 8 piston brake calipers, etc....
As rudimentary as these kits are, a nicely made machined aluminum saddle to fit on both sides of the frame would make these Chinese kits so much nicer. This kind of a build won't take long hard bumpy rides. Putt putting around town will be ok.
Good video . I put my strocpet on backerds so now I need to do it again
Guys get the gear adapter that clamps around the hub. It can be had on eBay, bike berry, kings motor bikes, Amazon, and other sights. I got mine from bike berry with a gear for $75ish plus shipping. Less stress on the spokes, and easer to change gears. That and the chain tensioner that attaches over the motor drive gear. In my opinion those are the 2 important upgrades.
I watched your videos a while back and today while checking for a few parts I needed for my sons dirt bike the engine kit popped up as something I might be interested in so I ordered one and think it will be fun to install since three bikes are sitting in the shop doing nothing. Video is helpful but will be making a few different changes added that I noticed need to be done to install the kit that I think are prudent.
Good video Steve thanks for doing it.
Very nice job with explaining how to proceed.
Key word for today: chain breaker. For sale at most discount stores for under $20. Works like a dream when removing chain links. Takes less than ten seconds per link. Invest in one. They are handy
I bet two of them until I spent back some money and got a motorcycle chain breaker much better. 13 piece set like 12 bucks
Very good detailed video. Really nice job!
Pac-Man washer? Metal bee? Interesting!
And the ‘ferrule’ on the spark plug is for ‘push fit’ spark plug connectors... (these have RF suppression to stop the high tension voltage required to induce the spark, from causing radio interference) remove the ferrule for the older ‘tab’ style connector, using the threaded ferrule as a nut to hold the tab connector on the end of the spark plug... but ideally replace the older style connectors with suppression style (not applicable for this build - already supplied)
Thanks for showing all the steps and for posting this very informative video... including the corrections that you could’ve edited out but didn’t, showing that mistakes can be corrected. The modifications to the mounting bracket also shows how it’s possible to troubleshoot issues! Cheers!
Buying mine soon thanks for the video :)
having a book that's in color makes it very nice
Nice motorized bike build!
Got mine it's amazing
Very good and informative video! Thank you!
Great videos keep the good job and thanks for guide us on motorize bikes. Hello
Hey each bike is little diffrent and old tire rag joint will be diffrent thickness ( can be resized ). That back wheel sprocket can be moved in or out but what matters is clearances, it is tight there. Both for chain rubbing from and chain rubbing tire. Have to just see what fits best on eack build.
Thanks for posting this video. It's very helpful. I'm thinking about putting one of these kits on my Specialized Crossroads which is a 24 speed City bike or maybe I'll get a new one speed Huffy cruiser. It looks like it will be a fun project and esp. fun once it's done.
Realy good vídeo. Thank U amen
Nice build!!!
Awesome video, thanks!
There are so many "little pieces of metal" in this kit, LOL. Seriously, though, thanks for the video. I'm expecting my first kit to come in this week and am looking forward to building it. Your video is helpful.
John Cuzzourt how did it go?
Just want to say something: Do a full tank of 16:1 fuel/oil mix, then a 20:1, then the final mix is 31:1.
ive found 20:1 to be very oily and preventing the motor from having good high rpm performance.
31:1 is the best or even 40:1 but i havent tried that yet.
This was a better How To Video then your 1st one.Thanks for showing more Step by Step ! Although I did want to hear it Run
Because some motors come Lock right out of the box. I WAS HOPING ON ANOTHER VIDEO YOU WILL SHOW HOW TO UNLOCK THE CLUTCH PLATE IF ITS LOCK AND WHAT EXACTLY DO TO UNLOCK IT AND WHY AND HOW IT GETS THAT WAY!!!! YOU DO THAT VIDEO IM SUBCRIBING !!!!!🙂 I THINK ALOT OF PEOPLE WANT TO ONE OF THESE REASON ITS WHY ENGINE WANT COME ON RIGHT OUT THE BOX AFTER INSTALLING IT! REAL GOOD VIDEO DOE !!!!!!!!!
Another great vid bud
Awesome Video!😍👍
The Pipe/Spout is actually called a 'Inlet Manifold'. Nice video.
Under your motor mounts use a thin piece of rubber or wrap a piece of cut inner tube around the frame to help with vibration.
To relieve the stress on the bolts coming out of the gas tank take two extra nuts run one all the way to the gas tank
For my kit, instead of bending the muffler, we filed out the mounting holes on the muffler so we could just angle it to clear the pedals.
But then it doesn't line-up with the exhaust port, like it should.
@@rooster6057 Yeah it does. I filed out the holes at opposite angles so it just twists. The actual exhaust port stays in the same place, it’s just twisted a little.
I'm going to use your video to build my bike when my kit arrives next week. I haven't bought a bike yet but I'm considering a cranbrook cruiser from Walmart as they are around $92 after tax. Though I was also considering a mountain bike with gearing like maybe an inexpensive 5 speed. I will be using it as a main mode of transportation for a bit so I'm curious what others think.
Just a note that you reversed the 16:1 and 20:1 ratios in your explanation. 20:1 is less oil which is what you'd use after the 16:1 break-in.. Thanx for the video.
Penny Underwood I use 34:1 ratio after brake in more power less smoke and still enough oil to lube the engine I have 1,300 miles on my engine running the same 34:1 and it’s still going strong
Joe 1 thanks for the info!
Giovanni Minotte i’m definitely going to try that. Could be fun to blow the engine anyway, i love an excuse to take something apart
1:30
or.... just let the air out of the tire.
It’s a lot easier to remove the caliper pad
So when are you going to do your first four stroke? Love the video thank you for your time
Hm. That's interesting. I also have a full colour assembly guide and it says the concavity of the sprocket disc is inward towards the spokes "this helps keep the chain closer to the inside of the wheel". Your chain would be running further from the interior (mid line) of your wheel if the sprocket disc was fitted the way you're showing it. Having the chain running as close as possible to the spokes reduces wheel-twisting torque.
Great channel!
It looks like the backend on the engine is alittle high up. If you leveled it more do you think the muffler will clear the pedals?
I wanna build this and i have the exact same huffy as your other one but no torch.
use some bike tube rubber under tank and over brackets for protecting and shock mounting.
Just letting everyone know, don't use the fuel ratio they tell you to use, start mixing at 20:1 and burn two tanks then go to 30:1 and give it a couple more tanks, then burn 40:1 forever after that. These are Chinese made engines and the Chinese use cheap regular motor oil. If you burn to much oil you have a chance of blowing your head gasket or having oil leak out the exhaust.
I
Yellow Rose I've never heard of Chinese oil being sold in the USA. ??
Informative video.
Question: What is a good gap measurement on the sparkplug? What is a good fuel/2 stroke oil ratio to start with and how many miles breakin to change ratio on average?
Also saw one other gentleman take the trans cover off and grease the tranny. Looks like a good idea to use.
Make sure the 4 bolts on the head are tight. Be sure you have a heavy duty kickstand.
Wider brake pads.
Use plenty of black plastic cable ties.
I would stick the front brake lever on the left handlebar with the clutch. Rearview mirror too!
Tall person? Get a longer handbar stem!
Wear a helmet?
Best video 👌 by far
GREAT VIDEOS
Since this is an 80cc engine I found a pull start that can be installed on it for starting it instead of pedal start but I am wondering if doing so would you still need the clutch for it plus can a jackshaft be used so that along with the pedal assist the gears can also be used from the engine in other words using the engine to power the bike gears also
I hope my second, goes better as yours did.
Great video! I put a 50cc kit on a nice mountain bike somebody left at the local dump. It's been great so far. I'm wondering if you ever found a solution for the brake on the left. I just put both on together. I need to keep in mind the top one is the clutch but it became second nature after a short time. I've never seen a 2 stroke engine that requires so much oil. Normally they are 40:1 or even 50:1. One of the comments from a viewer said 16:1 and 20:1 is too much and may even blow the head gasket. Have you heard any more about fuel/oil ratios? The only thing I can figure is that they are relatively crudely built engines out of sub standard materials and might seize up with less oil.
20 TO 1 GAS MIX IS 6.4 OZ. OF 2 CYCLE OIL TO 1 GALLON OF GAS.
16 TO 1 MIX IS 8.0 OZ OF 2 CYCLE OIL, TO 1 GALLON OF GAS. AND YES, I AGREE WITH YOU ABOUT ETHANOL, DO NOT USE GAS WITH ETHANOL IN IT !! IT WILL MELT THE FUEL LINES RUIN SMALL ENGINE'S AND GUM-UP THE CARBURETOR !!
that chain tensioner is a death trap
@@Steve_Does_Stuff I saw one guy say don't use tensioners , instead remove links.
Slovenia is the country of 2 stroke mopeds (Tomos). About that oil you have, it is really important to have high quality oil, it will make engine run more efficiently and increase the top speed. I also suggest to get better airfilter and exhaust.
Also Switzerland (Töffli)
I enjoyed your video. How does the engine do an work with the 5 speed gear changer??
Could you get another set of nuts washers and brackets for your tank that wat the studs would take the pressure of the clamps not the base of the tank?
When i bought mine i got 2 different spark plug cables?? I think.....1 is longer and has 1 cylinder with mounting areas and 1 box wired on it dose it make any difference. Or im i wrong and its something else?
do you have to add any oil to the motor before driving it as I cannot see an opening for this or is the engine have internal grease in it so no oil ?
The round bit that goes into the carb is called the "float" 👍
No, it's called a throttle piston. The float is at the bottom of the carburetor.
@@MattC78
O yeah silly me 👍😭 yeah the float sits in the bowl 👍.🍻
Good video I just got one saved lots figure is it 20 to 1.st. or. Is. It. 16 to 1 break in then 20 to 1 I want make sure I get it correct
neat video. got my sub
Instead of scratching the metal for the hand throttle, I would suggest using a paint marker and paint up the stud so that when you put the clamshell together it'll leave a nice little dot on the handlebar to drill.
@11:15 - On my bikes I just grind off the stud and drill a small hole through the throttle clamp and line it up on the handle bars where I want it and drill a hole into the bars and screw it in place. That way you can't bump your throttle handle and brake the stud off when you're 10 miles from a screwdriver and the entire assembly twists as you attempt to ride ;)
2:25 me: pause the video, cuts one in a half.
Me two seconds later: :(
Jk im poor I don't have money for this kit
@@FoxSock Already buyed one, don't, it's a scam
Perhaps watch the video all the way through before attempting the install! In fact before buying the kit... to see if it works out for him in the end!
My issue is my tank when it has fuel in it it will be completely dry with in 2 minutes of letting the bike sit. so i am going to check the fuel shut off but even if that isn't working the carb should be holding all the fuel but it is not? Not sure what to do.
hey i have an identical bike that also clips the exhaust when i pedal and i dont really own a torch is there other ways to bend it?
Brake fuel is 16 t0 1 and after brake in Ii use 40 to 1 increase power and runs smoother with increased performis
Anyone else picture Saul from the show Better Call Saul when they heard this guys voice? Lol
Not really
I just put my chain on. When I try to petal, I hear this popping sound in the motor, and it’s extremely difficult to petal like there’s some sort of resistance. Did u have this problem by any chance ? I would love some feedback, Thankyou! And nice build 👍🏼
I’m setting up a 49cc 4-stroke with centrifugal clutch on an Onex Genesis 29er Black Cruiser. Why 4 stroke? No smoke, no vibration, pull start, and I still have front brake lever I can convert to disc brake. You gotta have the front brake.... believe me. Why 49cc? Keeps it street legal in most states. Nice video....Thx!
graftonreed 2 stroke engine kits are actually only 49cc as well they are just advertised as 66cc-80cc for some reason I love my two stroke the modifications for more power are endless port work, piston work, expansions chamber exhaust, balanced crank for no engine vibrations, reed valves, high compression head and pistons, bigger carburetors, so have fun going 25mph with your 49cc 4 stroke while I’m going 65mph on my 2 stroke in my opinion only 4 stroke that should be on a bike is a predator 212cc
@@giovanniminotte2951 65 on a normal bike that's just stupid... You should only go 25 to 35 on a bike with an engine on it.
What is the round threaded thing with like a bolt threw the center for have no idea what it's called and couldn't add a pic of it
Cheers
You shouldn’t need the chain idler. They make half links. If the chain is too loose, take out a link and add a half link
Just wish we'd have seen it running but very well comentating😀😀
In my limited experience with these motorized bicycle kits rubber washers are your friend anything that is thin sheet metal with one Anchor Point like your fenders or you that gas tank or really anything that's going to vibrate loose crack or anything like that put a rubber washer on it all your screws used Loctite like every screw even if it's only blue Loctite
I use red Loctite but that's only because I don't plan on it coming apart again in certain places
I'm excited to be getting my first kit in the mail soon and after seeing some other videos, your videos give me confidence to build it right. I will be using a 26" West Coast Chopper bike. Do you see any problems that may arise?
ken senopole who makes that.? I want to see a picture
Sorry they're not all the same especially if you go through Zedda Motorsports or Freds cnc machine. They balance and have better bearings or even iron cylinder walls
Don't see any follow up on this bike and motor. How is it going?
