Everything you need to make your own Motorized Bicycle.
I just built a motorized bike and I just wanted to say thanks for taking the time to make this video. My clutch works great out of the box, but after watching your video I understand how it works... Which will come in handy when I inevitably have a problem with it.
Could you do a video on the clutch itself, serviceable components on the clutch, how often to expect to need to service the clutch, etc.
Thank you! I just finished building my 1st bike and you answered my question just by going through a simple demonstration. Saving me a lot of research time. And in addition to that I wouldn't a lot more about how the clutch works and how it engages in disengages. Thank you so very much, your new subscriber.
hey i like the fact that you are detailed with everything that you are saying about the bike im still having troublewith mine and would like to get help
GREAT video! I've owned my 49cc Grubbee Skyhawk GT-2B for over 10 years and NEVER fully understood this clutch design:)-John in Texas
i really like how he explains everything in such great detail.great job and i apreciate your help alan
Its like reading between the lines
Well done, thanks so much, solved a couple of mysteries for me, you are a champion.
Thanks, we need more videos of motorized bikes, issues, upgrades & tips, thans, say hello, joe.
Thanks allen, great job, God Bless you!
I fixed my bent holding pin. Thank you for the video.
Great information I learn something new today.Thank you.
Thanks for info much needed for memory keeping
Very helpful Allen, thank you
Please make tutorial about bt80 clutch problem..thank you very much
I recently took the cover off where the driving sprocket is and noticed that when the clutch handle is pulled tight and the pin is pushed in the camshaft creates a lot of stress on the bolts holding the cover on (pushes the cover away from the engine). It actually stripped the longer bolt and inner threads closest to the clutch arm. Is this amount of stress from the camshaft on the cover normal? Is it possible that the camshaft was installed in the wrong position on the crank arm?
In the case of the clutch pins are hitting the inside of the outer case. Brand new engine. The cable arm is almost all the way to the adjustment on the case as well.
Yes very helpful video. I have a new motor. My clutch isn't engaging when I pull on the lever or when I push the lever by hand. I'll have to disassemble the clutch to see if the spring is to tight.
On a unrelated subject I noticed in the video that your chain guide is pulling down on the drive side of the chain instead of pushing up on the return side. What is that about? I've never seen that done and honestly it doesn't seem right. I guess there is a reason you do it, please explain. I'm always interested in what people think. It seems that you would want pure drive with no possible obstructions. But I guess it works for you.
You are completely right, the chain tensioner should be pushing up on the return side. This install was done in haste and without proper information. We are constancy trying to improve the quality and content of our videos. I'm not saying he was let go after this video, but he hasn't been part of our team since shortly after this video.
This video helped me alot
I once took off the flower nut and when I tried to put it back on the clutch had too much pressure against my direction and wouldn’t let me screw it on how it was before. Then it was engaged all the time
What happens if there's grease on the clutch pads?
Where did the ball bearing go? Thanks for your time
Very good information in this video thanks man!!
helped a lot, thanks.
I thalt this would help alsome engine and good luck
On one of my bikes the clutch is super hard to pull in so you think loosening the collar on the spring will help make it easier to pull in?
Hello, nice video, I just have a bike kit built a few weeks and havnt used it much, the clutch already seems off only after a few hours usage, I can't immagon it would have any of these problems allready or could it be faulty clutch?
Good video thank you
very good video sir
Why is every thing out of stock on your website like I was gonna buy it all at once but half the upgrades are out of stock
Does the bearing go in before the clutch shaft
Hi bike berry, in one of your previous videos talking about magneto contacts one of you guys mentioned weather sealing the chase. I was wondering if you could do a video on this ?
thanks,,,,allen u rock
Solved my problem, Thanks
Helpful helping my friend with his he needs to replace the shaft n the cover. This video was a great help thanks so much
Man my bike is a piece of... Just old. Well my chain locked up in the little clearance (im not educated on the parts) but the small sprocket on the motor part lmao! Anyway, the pin that engaged the clutch is not sticking out its about an 1/8 of and inch in! Do you think that bind could have damaged the clutch assembly?
Thank you ..
Is'nt there a little key that fits in there somewhere? I think so and if so you did'nt mention it.... Tks for the video but a little more in depth video would be appricated....
I was greasing the bucking bar, and all the ball bearings came out. Could you please help me on how to put th ball bearings back on place. thank you.
You are the BEST !"!"
I put a new chain on and when I reassembled the couch pin wall the way in
My clutch is locked in gear plz help
+lucajo16 I fixed it it was just the rotor was stuck
I found out the hard way that a Skyhawk has a different clutch shaft then the flying horse engine...Skyhawk has smaller keys, half moons...flying horse takes 2 flatkeys...Skyhawk shaft is also a bit longer...
very use full ty
What does wif mean he always says it
so if I can force peal it and start the engine without using the clutch then the spring is too tight? I yes do I have to take it apart again or can I just adjust the flower nut? my bucking bar
I am installing a flying horse 80cc. When i went to put the chain on, i took off the clutch plate. The inner shaft was stuck to the outer clutch. After a few taps with a hammer it broke free. Then, i notice that the push pin has no movement. even tapping it with a wood block and hammer, it will not move. Any suggestions. by the way, i bought it from you guys. Asking for help from your support staff also.....
My bolt on the sprocket side but a little sprocket keeps loosening and it won't engage anything I have to keep tightening it not sure what to do
Great video, thanks for the info. What was the deal with the chain tensioner? I've never seen one like that before, with the adjustment at the top chain. Is this normal? What is the advantage if any?
Yes, the tensioner caught my eye too and I'm curious as well.
He explained it above. Apparently the dude that did that isn't with their team anymore.
My flower nut stripped on my way home any tips
are there clutch bearings? my engine makes a screeching sound and wont let wheel turn smoothly, its also like at one area of a full wheel rotation it tightens up and hard to turn the wheel by hand with less force
did they have motorized kits for tricycles too?
Enrique J Cervantes yes they do but a bit harder to find but they are out there mostly 4 stroke witch means no clutch.
I need help, badly. I was riding yesterday, and when I was coming to a stop, I pulled in my clutch, heard a pop, and then I had no more clutch. I've been having to ride around without a clutch today, and I need to fix this asap.
I want to replace my manual clutch with a centrifugal clutch. Would cut down on all wires. Do they have longer clutch shafts on the output end? I have really wide tires and need the sprocket to stick out further than stock. Does anyone have any safe solution to having the sprocket stick out a little further. I can't bring in rear sprocket and have it dish side out I should prob look into a flat rear sprocket instead of stock one.
I need a new ball bearings. what size is it and where can I get 1
perfect Video
awesome
My bucking bar wont move. plz help. Already released flywheel, no change.
man I now there are machine that can make metal parts and pieces like clutch pin and bars and more hopefully you guys can come out with something high performance alot cheaper then a jack shaft so you can use your normal sprocket and shifter and simpler and easier to install so you can get more speed
I need to know where the ball berring goes Bc it fell out of the clutch
Followed the how to remove preload spring but still won't come out
My clutch is a bit hard to disengage. It takes more force to pull the lever than it does with other bikes I've built. My cable isn't the problem, and the flower nut is set good. What can I do to lessen the force needed to disengage the clutch?
maybe hit the gym so you can pull harder
You Are Great!
Do u know what can be wrong if every time I press the clutch it revs high
I' bought this motor and instructions are impossible, I opened the plate of the motor to attach the chain and a ball baron fell out .where does it go
thanks
My clutch out of motor moves freely no tention on it
I have a clutch that won't disengage..but I can't get the clutch shaft out to adjust it..
The main nut on the side of the buck bar keeps coming loose.
THANK YOU!!!
Luv you guys , thanks
my kit I bought off ebay came and I notice clutch bar was going out instead of in. anyway I took apart as much as possible. adjusted clutch plate and put back together. now clutch bar goes in normally but, is very tight. checked clutch bar when in normal position and it is engaged. With clutch bar in it disengages. This is backwards I think. Anyway any advice of fixing this problem? Help! Anyone. Please very frustrated right now.

Thanks good info.
When I go full speed on my bike it'll bog down and go slower, I don't know why. It also seems to be vibrating more than it did previously to this problem. This all surfaced after the motor was taken off of my bike and remounted.
Air to fuel mix is too rich = too much gas+oil and no air,
Remove carborator plastic cover

but you have to understand the push pin is to short I got the push pin several time and everytime I order one it was to short when it was all assembled the push wasn't almost sticking out were the flower nut is on the pad a lot of times to short and kind of sunk in the flower nut like it to short so it make it real hard to make the clutch pad work right with out making the pad slip when drive it and and make the clutch handle to tight to pull so you guys really need to exception on the those pieces and the push pin to make sure it long enough before shipping it out ya that the only thing keep to completing my project
But where does the bearing go?
If my clutch arm is in to far and it won't start up
Fired up my 49cc for the 1st time today...was running fine...then the little gear on the clutch is just wore compleately off

Sadly no the frame is to small it would take heavy modification
Possibly one of their friction drive kits or electric hub kits.
