How To Install A Motorized Bike Engine

- This video will show you how to install a 49cc 4-Stroke gas engine from a motorized bike kit on to a Beach Cruiser Bicycle. This is a step by step video covering installation and how to decrease vibration from the engine.
Something that I have done on my installations, with a similar bracket, is to flip the rear mounting bracket 'upside down'. Turning the whole rear side of the bracket upside down better aligns the the grove on the uptube and gives the mounting much better stability and seating. If you have the frame room, which it looks like you did during this build, having the rear side mounting bracket turned upside down, and moving the base plate as far forward as possible, will allow of the rear mount to form a V with the down tube, allowing the mounting plate to sit on the end of rear mount.
I have my bikes set up so that I can remove the entire engine, and attachment plate, off the bike by removing the 4 side hex bolts. The alignment is almost perfect, with having the rear mounting bracket flipped over, allowing quick removal/replacement of the 4 bolts to re secure the engine. Also makes it easier to install the entire mounting hardware, since you can set the bracket without having the engine already on the mounting plate, and pull just the plate off to mount the engine. Makes it so much easier to do maintenance on the engine with just pulling the mounting plate off each time, instead of having to pull the entire assembly.
Also, to help reduce a little more vibration, try seating some rubber grommets in the top mounting plate. I've found a few that will fit into the track that you can attached the base of the motor to, that reduce a little extra vibration, by not having the metal on metal, but it does eat up a few millimeters on how far you can shift the motor right/left, for chain alignment.
Keep up the great videos. I'm looking at putting up a few of my own towards the first of the year. Looking at putting together a Slugo Fat Bike installation in the next few weeks.
+Drashk Dza'lya Thank you very much for watching and for the tips Drashk! I've thought about flipping the one bracket over to accommodate the angle a little better but then the bolts that hold the engine to the bracket interfere. I would either have to do some modification to the bracket to clear the bolts, or raise the engine up higher so the bracket would be spread wider leaving the mounting bolts accessible and no where near the brackets. However I don't have the tools or machines to fabricate and I would prefer my engine lower for better lower center of gravity and more centered within the frame.
The rubber mounts for the engine are a great idea and also something I have considered before, just never followed through with yet.
Thank you again very much for the ideas and for watching! Feel free to post some pics and description of your build on the SCC Facebook page at

Have yourself a great holiday and I can't wait to see your videos and your bike build!
Great vid. But may I recommend to just use blue permatex on all bolts. Blue will take some work to separate, but red needs heating or a permatex solvent.If you don't need heat then you di't use enough.
Very clear and great info instructor quality experience and right to the point I don't need little weird jokes in between each step thankyou
U mentioned beefn up two strokes and i wanted to mention that you can do alot to upgrade certain 4 strokes as well. Expecialy predator motors
Good video thankyou you showed me all I needed to know. Again thankyou
Do you also have a video showing the whole install I'm wondering how you attached the sprockets
It’s pretty easy
Ready to get a four stroker. Where do you get your kits?
They are a dry sump 4 stroke. Can be mounted at any angle, just not upside down.
Damn you were being so precise but you stopped where i needed you the most. Can you please tell me why the carburetor has 2 male entrances for the gas hose?
would you say these kits can take you up a valley hill, easily? we have some good hills here.. thank you again!!
Thank you! Thinking of going f zero four stroke package bike berry cu it all should be compatible …kinda wondering about the contrifigalnclitch but go for it and learn before I go every day wishing I did lol …kinda wanted a little quieter and straight gas lotta decisions so far it’s goin with the package decision and it should open up a world of fun amd mods once I get tuning down stock amd all the fun bugs out sorry kinda excited here
Hi, great video. What engine kit did you use on this build? Thank you
Keep up the good work really enjoy these videos.
+Ryan Loy (Benskiman) Thank you so much! I really appreciate the comment and your support! I hope you and your family have an awesome holiday!
ok thanks for the great video and information on how to put it on two thumps up
Thank you so much for the reply bud. Take care.
I’m having difficulty installing the pedal assembly included in my Amazon 4stroke kit. Do you have a video about it?
The 2 - antivibration mounts, where do you get those?
Love this channel, Is it bad to put rubber between the mounts? I heard that it can put to much pressure on the mounting studs?
+LastGenGamer I've always kept it down to two layers and have never had a problem with it so far. One of my previous builds has about 3k on it with the same rubber mounts and still going strong. If you were to add too many layers then you would probably run in to issues with it. Thanks for the comment and watching! Have a wonderful holiday!
Sinister Custom Cycles thanks for replying, great video!
Great vid bud.The engine that you installed in this video,does it vibrate alot as the more gas you give it versus the traditional 80cc 2-stroke engines?
William Santiago i can answer that since i habe exprienced in both it doesnt vibrate as much as a 2 stroke its more of a light buzz but thay varies by your mounting bracket like the one in this vedio it wont be a noticeable vibration.
I thought most 4 stroke engines these days had an oil pressure sensor with an auto-shutoff...what happens when you go up and down hills? Also where did you get that engine and kit?
If you uses a motor with low oil pressure sensor its best to delete it because when the oil sloshes while your going up hill or turning the engine will think its low on oil and cut engine power .theyre designed for stationary application but could be use on bikes etc aslong as you delete the low oil sensor
What would be a good bike to convert that is designed for very tall / big riders? The only real bikes I seem to find that fit that category are from Worksman but with the lower cross bar I have my doubts about an engine fitting in there.
+Lacider I'm not sure what your definition of very tall is lol, but the bikes I get are the extended frame versions which means the frames are about 2" longer than a standard frame which for me at 6' makes all the difference and is very comfortable. You could also possible do an extended frame with a layback seat post which would give you a couple more inches as well. Thanks for watching and have a fantastic holiday! Any other questions just let me know! You can either email me at sinistercustomcycles@gmail.com or go to Facebook.com/sccmn
I got a question what kind of motor mount is it cuz when I put my 4-stroke engine on my bike I have to use a flat plate on my bracket because it doesn't fit around the fat bar and I think the flat plate puts it back about another quarter inch toward the bar that's why my stuff is tight but your bracket look the same as mine but mine has four bolts on each side of the chain slide?
Awesome job!!!
So what's the name brand of that motor so I could buy one .?
Can u do this with a bbr frame?
Where can I get one of those 4 stroke engines?
What bike is this your using?
This bike is almost perfect. It was very easy to assemble. ua-cam.com/users/postUgkx2YFGCCEkXKgqCOH-7vlvgb4L4hg4IrXI The fit was great as well. I am 5'11" and 160 lbs with a longer torso and rather shorter legs, and 55cm is a perfect fit. Every component seems to be pretty decent and durable except the rear wheel. It was a bit lob-sided and also the freewheel component is either missing a ball bearing or under lubricated, which prevents the wheel from rotating freely. Because of that, it requires more pedaling and also climbing hills a lot harder than expected. Other than the back wheel, I like everything else about it. Affordable and well-built.** UPDATE **It turns out the sound was caused by the tight chain tension. Once I loosen it up by moving the backwheel a tad bit closer to the crankset, the sound went away.
nice video. Is that whole motor and brackets you used is that a kit that I can purchase.
Yes it is bikeberry.com
Personally..... I would have put down 4 rubber grommets in the holes on the base plate then the engine. .... (and then tighten the engine down onto the rubber grommets, that way you can dampen the vibration far better)
Neat installation.
+The Shade Tree Fix-it Man Thank you very much!
Who do you order your engine kits from
How about just using lock nuts instead of using the lock-tight stuff?
What's the top speed in them 49 4stroke engines
YO BRO HOW TO INSTALL SIDE COVER RITE IN AND OUT SIDE OF IT 49cc 4 stroke
Thank you Adam
+Albert Michall You're more than welcome!
could you pull power from the magneto to power a light instead of using a separate battery??
magneto puts out AC , lights on bikes are DC.
Voltage would need to be regulated, dropped and rectified.
just use a DC dynamo.
I have a question for you I just bought the same engine as you can see it has three gas lines The gas tank only has one hook up where does the other two gas lines go or hook up to
Christopher Smith I just ordered the same engine and it also came with 3 gas lines and I'm confused
They are drain hoses for the carb
Drains
Tank a lot
will these work on mountain bikes with hydraulic disk brakes?
Vixen Timer if you have space yes but you might have to get caliper brake for the rear tho.
You would have to remove the rear breaks
Nope
Link for the frame?
Nice earings
used phone as a leveling tool? never knew that existed
did you buy a moped kit ? like on ebay ? could you post a link of were i can buy the motor
gas bike.com
I used to buy my engine kits from gas bike until I needed them to back up a bad product they sold me and then after finding out they spent more time misdirecting me and ignoring me I stopped going through them and am currently looking for a different vendor for belt drive 4 strokes.
i was considering using "www.kingsmotorbikes.com/apps/iwish"
Any good or bad luck with them?
I. M from Canada where can i get this
Robert fournier ebay.com just search bicycle motor
GOOD
where is the muffler?
9:55 OH QUESO!
How To Install A Motorized Bike Engine: Well, there's this thing called a 'spanner', and what you do is, hold it in your hand, and....
where can I get those engine?
Mesak Lalzarlien Sinate ebay.com
Can any one tell me where the fuel lines connect to the carb, there are three places on the carb for fuel lines.
I know it's been four months since you've asked this question but it's on the left side of the engine the same side as the pull start, it took me a second to figure out where it was when I had this motor I actually laughed when I read your comment because it reminded me of my frustration trying to figure that crap out before
Only one place to mount...the rest are drains
Could just buy some shorter allen bolts too.
Yes you could definitely do that, although I have tried that route a few times and spend more time searching for the proper length and thread than I do just cutting it down lol.
Ahould i gwt a 2 or 4 stroke one
@American Boss ty but I now have race cars
@American Boss ye might get one to play with again
@American Boss 👍
What 4-stroke engine do you prefer?
+glennspeeds For the price I love the HuaSheng! You just can't go wrong at all. At first I thought the cheap overseas engine would be junk but it's always held up just fine for me and with the same version in Honda costing 3 times more, I'll keep sticking to this one! Have a great holiday and thank you for watching!
iglobalbuy 49cc
Sinister Custom Cycles HuaSheng. Thanks!

Engine bicycle
Too much talking and not enough doing.
🤔REALLY ANY bicycle NEEDS AT least 6 /1/2 horsepower ! . 49 cc's Will NOT EVEN pull ANY bicycle down any hill much less UP ANY Hill
Anybody knows about any gasoline engine ALREADY KNOWS a 49cc engine will not pull a kid is 30 lb down any hill much less up any Hill YOU got have at least 120 cc gasoline engine
No brakes?
