- This video will show you the difference between the cheap rear sprocket kits that come with a motorized gas bike kit and a quality hub mounted rear sprockets adapter from Manic Mechanic!
Thank you for the amount of detail you put into this video. You made me realize what I was doing wrong and now this sprocket is just a pain in the ass instead of a dead stop to my entire build.
The rear sprocket was the weakest link in all 3 of my builds. I am very, very happy to see a great solution. Thanks for passing this on to us.
You're more than welcome! I'm happy to hear it helped you out!
Sinister Custom Cycles hey sinister costom do u think you can build a bike for me and use that sproket from manic machanic email me at lovefamilyforever2016@Gmail.Com thanks
I haven't built my first bike yet, but you have sold me on this part!
power that goes directly to the hub is how motorcycles evolved in the first place, so this video makes perfect sense.
I totally agree with you. Great video man. I have had been threw hell with my back rims on my motor kits I bought because of the cheap sprocket kit they put in it. It puts way to much pressure on the spokes. I have actually broke 9 spokes with my last one and had to take my rim to my local bike shop to get fixed. I put it back together to only break 1 more spoke. So I started researching into better sprockets and this kind of one is definitely worth the extra money otherwise the cheap one will only continue to mess up rims and spokes. Your video was the first one I watched because I want to see how big the hole is to go around the hub on the bike because I'm going to buy a bike without spokes and wanted to know if it will fit. Seeing this video reassured me that the bike I want to buy will work out with this better upgraded sprocket.
In looking into building a motorized bicycle and this is amazing. Love the no nonsense install of the better adaptor and adjustibility. I found it on amazon and got it saved to my list along with other parts I know Im gonna change from the kit.
the first sprocket was on backwards
It doesn't really matter
You also have the sprocket on backwards to where it's sitting closer to the rim
instead of sitting out away from the rim.
this is the answer to the biggest issue I had with these engine kits
That’s a nice design! I’m gonna look up manic mechanic
That's awesome, 14:52 thanks for that information, what can I do if my crappy sprocket doesn't fit over rear hub ?
I bought a Dolphin brand 2" CNC sprocket off of Amazon for my Walmart Huffy Nel Lusso cruiser and it works perfectly without any slip. Total was $56.00 with free shipping, Very good quality.
I have the same setup
Sinister Custom Cycles I have been using the stock sprocket that clamps to the spokes for about a year now and haven't had any problems with it. I'll admit yes, putting it on was a pain but I tighten it after each ride and still no problems
Hey as long as it's working for you that's all that counts. Oh, I don't have to tighten mine after each ride...lol
Sinister Custom Cycles use the red thread lock!! On each bolt!!
Yes hub adapter is simple and better...but the rag joint does have a correct way to do it. You don't need to put all nine bolts in at first. Put just the middle ones and get them bout 10 turns each. Then take rubber hammer and flathead screwdriver and true the sprocket center to the hub circle. Crisscross tighten all other bolts to be even with the middle ones. After every other tighten make sure your sprocket is centered...at this point shouldn't need to hammer tap it. If you want to move sprocket left or right for chain straightness then loosen cone nut on opposite side of rag joint while you tighten the coaster break arm. Maybe add a washer on break arm side. And you need to grind the lip off duskcap and bout 1/16 around the edge so that it spins freely inside of sprocket and keeps dust and sand and dirt from getting in your bearings which bust apart if that kinda stuff gets in between the bearings. I've spent 107 dollars on mine so far. I double nut and lock tight the rag joint sprocket bolts and have put well over 20 tanks of gas through it and havnt had one problem out of it. It's a bicycle, you can't just hammer down on it before getting speed up from pedal. Motors putting out 9 times the human leg is. Baby your ride and clutch drive it. Get speed and slightly pull in clutch lever just enough to pull the tension plate off, let the motor slow you down some and then release and throttle , repeat. Feels like changing gears but basicly not ragging the motor out. Works really good with reed valued diaphragm carbs.
I did that at first, with the lining up of the inner circle to the hub circle, but those Chinese sprockets are punched out so weird, the inner circle will be lined up nicey-nice but the tooth tips and valleys will be rising and falling if you spin the wheel and look from the side. look closely at the tooth tips and the bottoms of the valleys as it spins. you WILL see the true path the chain will take, regardless of the center hole alignment. much easier to do when the wheel is spinning slightly and you don't focus on individual teeth- you will see the rise and fall of the tooth tips and valleys. its BAD!! (on most) and will stretch a chain to shit butt quick. it's the rise and fall of the valleys (not the tooth tips) that has to be centered and even on these crappy sprockets. lining up the center hole is only a ROUGH guide and is only the beginning. installing a rag joint sprocket really IS a pain in the ass no matter how you slice it.
Has your MM slipped yet under motor torque and wrecked your spokes ?
Plenty of others have reported that problem....lol
tape comes in handy for that for the nuts and bolts on the sprocket
+Justin Champagne Hello Justin! Thanks for the heads up lol. I should've been paying closer attention to that but I knew I was going to take it off so it didn't even cross my mind. Tape would've helped! Thank you very much for the comment and for watching!
*Im on the verge of buying my 1st Kit. IMO they should have the cnc Sprocket & ADAPTER AS AN OPTION in KITS.. I UNDERSTAND ITS A GOOD UPGRADE & It makes it easier to install for a beginner... 🤔*
"This is one of the absolute dumbest things I've ever seen in my life." Well put, my friend! I just bought a kit w/ the 1st setup. It is a huge pain in the ass!
Its the only way that i can get get to work still lol ive tried the hub adaptors and unless u cut a groove into your hub and the adaptor and make a keyway to lock it into place on the hub i have not found a way to get the adaptors to NOT slip on the hub the second i let off the clutch and rip apart all my spokes
For centering the rag joint sprocket I found a thick rubber O ring that fit in the gap tightly to center it. Total time with that for me was about fifteen minutes the first time. I do eventually want to upgrade to a hub mount but that's going to be a month or two. It's held up for a year and a half so far though.
well,.. you got the center of the sprocket lined up. but,.. spin the wheel and watch the valleys between the teeth as they spin by. look closely. ill bet money the valleys are rising and falling even though the center hole is aligned dead nuts with the hub. that's a chain-killer. TRUST NO CHINESE PARTS
@@robertsmith5323 I don't have any vertical variation but a minor amount of side wobble which is very very slight I have to sit and watch it to see it. It's a rag joint still so I will be changing it anyway. Or even possibly changing for mag wheels with the sprocket mounted on it but those are like three times the price.
slight side to side wobble like that aint gonna add up to anything. the first time I installed a rag joint I was brutal with the hammer adjustments and i deformed a tooth because I had a micron of wobble. I should have just left it
@@robertsmith5323 yeah probably cost you more in the long run
How do you get it to be perfectly straight with no wobble?
Don't use those sprocket adapters it's a bad design. At first they sound like a really good idea, but they just tear your wheel apart. Only two bolts clamping to your hub, usually isn't enough to prevent the adapter from sliding under all the torque it has to endure.
i buy alot of parts from them and there great hands down. and im all the way out in ont canada. great video.
I just installed the cheap;o stock one in about 15 minutes taking my time and using a drill and a open end wrench and lined it perfect by eye as I went no backtracking... but this is my 7th-8th rodeo or better... pretty good but for sure will upgrade to the hub mount as I upgrade the whole stock kit into being something more powerful :}
So it's almost as much as the kit it's self ! I use the factory sprocket with a 41 chain and it's good.
Simplicity is beautiful (Sprocket adapter)! 8)
or just a disk brake mounted sprocket, those hub adapter things slip, heck even bikeberry had one slip on them ik they aren't the smartest dudes, but look at their advertisement for it.
This has helped me so much thanks man!
that sprocket being off-center not only causes issues with your chain, but it will also destroy your spokes on your wheel, the jack shift kit will use your factory driveline
+countryguywithcamera Good points! Except keep in mind that the engines kits use a 415 chain and the jack shafts do use the factory drive line which is much smaller and not at all designed for that torque of the engine. Jackshaft kits are great you just have to baby them or you'll destroy you factory chain and derailer in no time. Thank for the comment! Happy holidays!
I have the same problem over and over with some wheels! Literally have spent hours trying to get the sprocket centered and never get it! Some wheels work just fine, but mostly I struggle like crazy with these rag joints! I hate them!
On the first one, to center it, I’ve seen someone else insert zip ties all the way around, not tying them, just using them as a place holder, because they were a good size to space it all the way around and keep it consistent. Then after tightening the bolts, removing the ties.
Hello! Sorry for my English. Rubber rings provide cushioning. Depreciation will disappear with such a mount. What to do in this case?
Depreciation is very important .
I have one of those rear sprockets and trust me it was a pain in the ass putting it on it took me 2 hours to get it completely done by then I just wanted to throw the damn thing through a wall because that's how aggravating it was
Best videos out there can't wait till you make more
+SCOTT HERTZ Thank you so much Scott! I really appreciate the kind words and support!
this viedo help me too putt on my sprocket on my fatbike with motorkit thanks
Bsa made an adapter like that in the 50s
Thank you for showing me what I need to do to get it mines off because I'm catching hell trying to get her off
Great idea! However, will this still allow the coaster brake plate to mount so one can use that brake?-John in Texas
If you turn the standard sprocket round you will have more clearance for your chain duck
Like it's supposed to be
Do you have video of how to take a break arm off a beach cruiser Tire because that's the exact same Beach Cruise tire I just took to my friend to try to get that part off please send me a link
Awesome video!!
SUPER ADAPTER, SEND THE LINK TO BUY IT PLS...
I had to modify a CNC Hub….the rubber they include will not last, and will freely rotate and begin to murder your spokes……With the cnc Your gonna need to install a key chuck……I do this to all my customers bikes…..at times I use the original setup, I pound a centimetric ring in the middle of the hub, and continue to assemble the hub….I use a Metal curtain rod holder to install in the the rag setup center.
Use a rubber mallet.
OK this will not work for everyone but if you have a sprocket that came with a hub adapter and it not only has the 3 large holes for the adapter but has 9 holes as well if those holes are more like a slit more like a rectangular shape, round at the bottoms and tops, use carriage bolts. figured it out the other day, perfect fit. Almost perfect alignment vertical and horizontal (got lazy at the end, could be "straigher" on mine 🤣).
Do the ones from Maniac Mechanic come in different sizes with more/less teeth?
Excellent video and hats off to Manic Mechanic mmbikeparts.com
Hub adapters are wonderful but they do not work with disc brakes. Mine has dual disc brakes and I had to grind out the center hole in the sprocket to 53 mm. It started out at about 33. What a pain in the ass.oh and it's a Fat tire bike so let's hope I have enough chain clearance
You had me until the $100 bucks😂 my kit cost under $100 bucks.
It only 35 buck for adapter
@@joshpreston8233 Yep, cheap clones are $35-40. I will be getting one after I get the bike it will go on, once I measure the hub.
Very helpful, ty
What prevents slippage?
Great video!
+Rick Bell Thank you very much!
can anyone help??? the sproket always has at least two or three consecutive holes blocked by spokes......if i force all 9 the sprocket is way off center
Eu compraria de você uma toda dessa completa já com pneu, você venderia para o Brasil?
I agree 100%
i used black tape until it fit snug then tighten and aligns easier ,until i get that beast of a sprocket kit ,peace
how do i measure my back wheel hub to know what size sprocket adapter to buy?? or all they all one size fits all type thing with just different size sprockets??
So i DONT need to dremel the sprocket!?
you put the sprocket on backwards have the same rim
is there a sprocket adapter that will work with an hourglass shaped hub? I would have to have one that could mount to the center of the hub as the hub tapers bigger towards the spokes...
Really, if you are going to bother with the hub mounted sprocket you might as well get a disk brake adapter, its directly bolted to the hub through bolts and doesn't slip like these expensive hub adapters (quit denying that they do, even the 38cc 4 stroke bends them) and doesn't progressively bend your spokes like the rag joint does, not to mention many times it's cheaper as all you have to do is buy a sprocket, unless you decide to go for a mag wheel like I did.
You would have room if sprocket wasn't installed backwards....
id like a link to the website for the better engineered sprocket to share with my fellow rider friends please tgis hobby is huge in orange County
26 inch wheel?
Its the one reason I never bought one. Just got the kit, placing my order come the first
Sir which is better to use from this two types of spracket
He’s right…there is no way to get the back sprocket Alignment to be straight
A question how much should the bushing measure to put on the clamp? Thank you
EXCELLENT
Great video,very informative. This is a big problem for most people. I'm sure this sprocket adapter will solve my problem. thanks! regards #datadiggerdon
This save the spokes
Ohh nice!
The sprocket adapters have dropped in price, I got a 38 teeth center wheel mount, with an adapter for smaller sprockets, I think I spent about $35.00, all said and done.
These are way better than what comes in the kits, as you can switch them out, go to different gear sizes.
I have been looking into a gear box for the the engine itself, have seen some pretty good ideas, but I think gearboxes are going to be the next biggest step in getting the most out of these little engines.
I have a 110cc 2stroke, it's a beast, have had little trouble with it(though I am not comfortable going far with a bunch of tools) , but I can get up to 40mph on a flat surface, and can get 30 up a 20-30% incline. In fact this bike is too fast for just riding, it's meant to go fast and furious for long runs, I just give her a break to cool down every hour or so.
Thanks for posting this information, I am always looking for new ideas on mobility without using any cars or trucks, I don't want to get a licence, I don't need one, and I would love to put together a couple bikes to make a 2-4 person "car type vehicle, with enough space in the back for a living space(when using a pop up tent is not feasible, or when it's cold and wet.
Thanks again for your time and effort into your vids.
Is there a way to install one and keep your rear disc brake
to bad these things are close to being expensive as the engine kit itself especially when you on a budget oh well.
zombiex 2003 ,,, if you take the dust cap off and put the sprocket on facing the right direction it fits perfect,,, you only need one rag joint on the inside of the spokes,,,. You do not need the second rag joint between the sprocket and the spokes,,,. If you cut your chain down properly you don't need a tensioner that'll end up in your spokes,,. !!! Set your rear wheel all the way forward until the chain stretches and then move your rear wheel back to Snug your chain back up,,,. !!!
32t gear and hub billet ebay $29 shipped.
@@s14duma Yep. Only problem is the cheaper ones can shift - if you key them with a dremel and woodruff key, thats the perfect solution for cheap.
@@williamwinborne3253 had that happen but then everything bought off ebay never fits first try. Simply shave off a bit on top and bottom of alloy hub with sand paper on a flat surface. Take off a wee bit and good to go! Few months so far no shift, no key, using tiny bit of red loctite. Good to go!
bought from wish 1 week ship n $111.00
I'm looking for a good way to put a sprocket on the rear for a 212cc engine, any suggestions?
Thank you
What nobody tells you is how to do this on disc brake or if it's even possible
remember to get heavy duty rims with gauge 12 r 11 spokes , r the wheels will break ounce r twice r 3 times a year lolol
I just left one ring off cause bolts got shortened 😅
Awesome video! I'm planning on making a bike with a 66cc 2-Stoke kit and I was wondering how well you think a Huntington bike would hold up to about 3 hours of use per week. I plan to use rubber mounts to absorb some of the engine vibration, but I'm still worried about how the welds would hold. I was also wonder what springer fork would you recommend? Can't wait for to see more videos, thanks!
+Skit tles Thank you very much for watching and for the compliment! All my builds have been with the Huntington bike and even though 4 strokes have less vibration I keep a close eye on my welds and after over 6,000 miles I never saw any wear on the frame or anywhere else structural for that matter. If you're going to add rubber mounts on top of it you should definitely be good. As far as a front springer fork, go with the heavy duty Monarch fork. It's not only extremely beefy it also has the option for a front disc mount! I'll be using this fork for both my current builds with the disc mount for extra braking power. Thanks again for the support! Any other questions feel free to message me at sinistercustomcycles@gmail.com or Facebook.com/sccmn
Thanks for the tips! Do you think you will every make a tutorial on how to install front brakes?
+Skit tles You're more than welcome! Yes I will actually be installing the Heavy Duty Monarch Springer Fork with Disc Brake Kit on both my current builds so I'll more than likely break that in to two videos, one for the fork install and then the other for the brake install.
Great! I'll keep an eye out for them!
+Skit tles Sounds good, thank you! If you want to keep up with smaller updates go to Facebook.com/sccmn
,,, you're installing the sprocket wrong,,,. Remove that dust cap in the sprocket fits over it perfectly you only need one rag joint on the inside of the spokes you don't need II rag joint between the sprocket and the spokes,,. !!! If you spend the time to cut and adjust your chain properly you don't need a tensioner that's going to end up ripping out your spokes,,. !!!
man could you please show how the sprocket on the other side goes on and comes off? the smaller one thats attached to the pedals? I'm rebuilding an old beach cruiser into a motorized bike, I bought a new 26x2.125 rear wheel that I need to put an 18 tooth on, I got the 44 tooth on one side but I cant figure out how the 18 tooth one is going to work with the pedals
Michael Mountain if im understanding correctly...u need to take your rim to a bicycle shop and tell them what you want. They have a special tool you need to take the right side sprocket off.
Can I install the kit on a geared bike?
Where i find this spoket
Qual o melhor cubo da roda?
buy the bbr upgrade sprocket, 3 bolts compared 2 to 9
how to avail, sprocket??
I started my first build, and the rear spocket took a little time but I got it in and centered. Now the problem I have it the rear wheel wont spin freely anymore. I put it back on the bike and it is extremely hard to pedal....what did I do wrong???
Check that you didn't tighten down your bearings so tight that they can't move.
I appreciate the response. I found the problem. The rear sprocket was pressing against the dust cap. Had to grind it down
Also to get the sprocket to be true all you need is a vice and a level
that does nothing for oblong
what is the size of rear sprocket adapter ?
This kit serve for 4 tempos engine?
What if you put a small sprocket .will you get higher top speed?
Is there any place I can buy a pre-bent arm?
Since You never got there.... You can't tell us how hard it was to do the Job. You showed Us how an unmotivated person who really didn't want to bother would bail out... Success is just not Possible, that stupid thing!
Excelente
Will this fit on a shwinnn occ chopper bike?
what size are the hubs on the Huntington?
Yeah you didnt mention the price being 75 bucks for it..as much as the cheap kit. I would have liked you showing this video as an upgrade for more experienced cyclists...
there are some knockoffs that are a bit cheaper now on ebay, A good one still costs you about $50 vs a $25-30 ragjoint.
Damn I got problems too
See I didn't have a lot of money so I couldn't buy that at the after so I had to make the one I had work and I got it on there correctly and it works perfectly fine for me even though it was a huge pain in the ass
how much for a decent kit with a non exspensive motor
hahaha the sprocket is more expensive than the engine kit lol
micah evans about $120 on amazon and $80-90 on ebay
How do you deal with tapered hubs? Are there adapter or kits with the right sizing?
You don't
Genius!!!
whats the chain break tool you use to break the chain that comes with the kit?
The chain break tool doesn't come with the kit. You can pick up a standard chain break tool at any bike shop or hardware store.
