Drill a hole all the way through adapter tap it and use a Allen head set screw, put a small dimple in the hub for the screw to set in much easier and faster provided you have tap die set
I'm so glad you posted this... I bought a hub adapter and sprocket a year ago and the diameter of the hole in the adapter was almost 1/8th of an inch under one inch, and I had ordered a one inch adapter. I spent a lot of time arguing with CDH power and the vendor on amazon... I ended up scrapping it and keeping my 9 bolt setup. I recently bought a new hub adapter and sprocket and it's a much better fit, but it isn't perfect. I was thinking of doing some of what you suggested already, I've already done some modification with my angle grinder (only power tool I have besides a dremmel and a drill) but this clears things up so much! I was concerned the adapter wasn't clamping to the hub as good as it could have been...
Awesome Idea, I bought the 49cc four stroke kit from BikeBerry and loved it. Kit was very good quality. The rear sprocket adapter I bought from y'all I sanded then epoxied. Worked good, but I did have to redo it once. This is so much better. imo.
Thanks for the insight Phillip! Epoxy has its place but it does tend to give out from my experience as well. Once I learned this and routine tightening I’ve been good.
Yeah it didnt occure to me that the adapter could slip because its perfectly round in the middle but doing what you did is a little to far outside my comfort zone, i guess it helps to have a machinist backround huh... tks again brother
Great video and very informative. I had an idea to drill and tap a hub adaptor then run a hardened screw through it to a flat spot I'd grind on the hub.
I agree. I wondered why I couldn’t drill, tap and set screw it in place. Only thing I can imagine is the corrosion between steel and aluminum, but it’d be a ton less work and no risk of blowing through my hub with a dermal. Also, they sell this thing, why not have it cut for a keyway prior to shipping? They sell the stuff but I still gotta dremel, grind, cut key down, remove spokes and everything to grind down a new part to fit? Lmao
Thank you very much dear Master! I have learned a lot from your tutorial videos. I really like your channel. I have one problem: About how to put the Brake Disc and the Star in the rear wheel at the same time. If there is a video about this, I will be very grateful to you. Thank you for your hard work. I wish good luck and prosperity at your home and work.
Hi Tony! Great video! My Schwinn 27.5” has factory disc brakes. I saw your build that has rear disc and a drive sprocket from the factory. What spacing do I use between the sprocket & disc and will the factory caliper offset work?
best advice in the whole comments man. thanks. if the spokes break and you're 4 miles away from home... thats a 2 hour walk. if you're lucky it's also cold
When u sent out the adapter why not sand it, groove the adapter n include a woodruff key.. then all we'd have to do is dremel out the hub.. and maybe tweak the key
I agree, or at least include a little booklet or something that will tell you this stuff, I already scraped one hub adapter cause I couldn't get the thing to not slip.
They are a reseller, they are NOT a shop. They provide customer service for "YOU' to figure out how to use their product. Honestly, they do this very well. Have they any Creative freedom over the products they are selling, I am sure they would modify it all. As of now I don't think they modify a single thing in their kits, but they do provide slightly different mounting hardware.
Just used this method for the first time and it worked great, the hun adaptor and sprocket are on the hun so solidly now. Makes a total difference and less worry for me at high speeds! Thanks for the lessons, now can I get a free set of the mag wheel kit from you guys at Bike Berry? Lol.
Never had an issue on a coaster break them slipping. But you can use 2 pins or dowels. Drill and ream for 2 solid dowel pins. Grind points on them position on wheel and hit with hammer to spot hole. Do what you need to do to drill the 2 holes out on the wheel and install. For a geared wheel I machined off the 2 mating surfaces and tightened it so much it compressed to a slight oval and it can't slip. I use the button heads so the slight mismatch is minimal.Also measure the bore and wheel axle enclosure or what ever its called and use appropriate aluminum shim stock to match perfectly.
In response to Bikeberry, I took your sanding tip, used JB weld for my 1 to 1.1/2 half spacer and just spot welded the screw heads for safe no return instead of blue thread lock. The outside of the hub is steel and the Chenase 36 sprocket was also steel so five more little tacks with the wire welder and no give and no chance of keyway breakage. You guys also did a great job. The setup is different for your coaster break. It might not work with that concept.On a 7-18 speed you have a protruding mount that joins the diameter of the sprocket o.d. It worked really well. I’m not downing your idea at all. I used a 415 link with epoxy years back. That’s definitely a stronger setup.Best of luck to you and thanks again. Very well explained here and I would be happy to send you some photos or video of mine.For someone who doesn’t have shop ability .....?
That’s some great insight my friend. Thank you for sharing. Yep, this specifically for the coaster brake. I’m going to test the set screw in smaller hubs. Appreciate you!
I just mentioned that/similar idea above. Use 2 set screws or 2 small bolts with round heads. Drill 2 holes in the hub that the set screws/bolt heads slide into. Like 2 dowel pins for wood working they'll act like 2 wooddruff keys. Easy to measure/line up, the 2 holes to drill, just slowly tighten/clamp the hub adapter down until it starts to make 2 small dents into the hub. Take it off and it perfectly marked where to drill. I wanted to weigh a hub adapter setup & compare it to the rag joint setup weight. If the rag joint setup weighs much less, I'll stick to it. If weights are close to even I'll switch to hub adapter.
I always use rag joint and if clearance is issue I can always make a spacer to space it out if not then I will go to hub adapter and better longer bolts file x grooves in the bottom where it touches hub rough sand hub and use epoxy and red lock tite it will never move again when I’m done and the hub will explode before it gives out
The rag joint setup itself actually isn't too bad on a 36 or 48 spoke wheels but those 9 stock rag joint bolts & nuts suck & break easy.....I went & got 9 strong grade 8 nuts & bolts for like $2 that I can reuse & also torque down tighter.....Seems like there are lot's of little tips & tricks that can turn a crappy stock engine kit into a decent one. I wasted $15 on the wrong spring chain tensioner. I bought the one that mounts to the engine. My friend has a much better spring loaded one that mounts to the rear frame where the stock one does but it has a pivot lever, spring & better chain roller. Too many "know it all" idiots online recommend the wrong parts. I shouldn't have bought the engine mount spring loaded chain tensioner but so many idiot videos claimed it was great. I bought $15 thumb throttle & $15 dual pull brake lever. Then later seen a $15 dual brake lever/thumb throttle combo. Plus I haven't used my $35 hub adapter yet, so about $70 down the drain. Not enough room to use my thumb throttle with my dual pull brake lever. I might be able to trim the clamp bracket down enough for room.
Putting a keyway in my hub as you said totally destroyed my hub. It wiped out 5 spokes ripped the hub wide open and the hub eventually bent and the sprockets on both sides wobble. Now l have got to buy a new wheel.👎 Bad idea!!!!
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 .
What size sprocket will give me the most speed I just went from the one that comes with the kit to a 16 tooth and didn’t really get much more top speed
I have stock mag wheels that the bike came with and I was wondering if this is the way to go by default or if I need to buy a set of spoked rims or motorized specific bike wheels
you could buy mag rims with a built in sprocket but you'll need to go to disc brakes. Or you could buy a traditional spoked rim and use either the hub mounted adapter like the one in this video or the super PITA 9 bolt mounting method that secures the sprocket to the spokes with two rubber donuts and some metal brackets, it's the setup I have now but you need a lot of patience to get it properly centered/aligned.
Every motorized bike rider needs to do this or know how to do this unless they're using a MAG wheel as I've learned from experience The hub adapters slip and break spokes without this key way installed
The pressure of the coaster break concerns me. Plus keeping the hub round. Try folding a piece of fresh 300 grit sand paper with epoxy inside the fold and retain the metal on the hub and adapter. Just a little thought. Blessings to you and yours. 💯
Much easier to just buy some double sided sand paper and cut it to the exact length to wrap around your hub without over laping. They sell it at plumbing supply stores. It will give some grit for the two surfaces to bite onto. Its called "sand cloth" and as you tighten it down it will crush the sand paper and make it impossible for anything to move. Use lock tight and re torque it a few times after use and your good to go, forget about it
@@nicos9937 I used 120g but wore it down a little bit on a piece of steel pipe so i imagine closer to 220 after that or somewhere in between. Did it to make it thinner cause i was worried that id throw it out of center which is the whole reason of having a hub mount sprocket but after doing it I made two sharpie marks, one on the hub and then on the adapter and i watched them for 2 weeks of 28miles a day and it the marks stayed true. I went with a 44T sprocket and im 200lbs so theres some weight and torque there.
Putting two of the adapters together with 3 longer bolts would've been quicker, and it looks cooler, lol, you could use this style of adapter, you just have too cut the spacers off one, making it flat, and drill out one so the three bolts can go all the way through, the Chinese adapters with the three removable spacers are best for doing the double adapter method, all you need for them to work is three longer bolts, and put it together, no drilling or grinding needed.
Thanks for the video.For you guys that are beginners with motorized bikes even if you don't have a hub adapter just using the normal nine screws and bolts through the spokes eventually breaks the spokes too. It just don't happen immediately. So don't be content with it and we did happens just take the extra time and make the key way or use a MAG wheel otherwise your going to have to do it anyway. I'm speaking from experience and I know.And Something else when putting loctite on one screws and bolts cover it up with waterproof substance as I think the rain dissolves the loctite as mine came loose shortly after the rain got on the screws and bolts which I did have exposed to the rain
I agree with you 100% Really what making the keyway does it it prevents it slipping as much. The thing about the hub adapters are this, your hub actually needs to be slighter bigger. If you're buying a 1" hub adpater, your hub should be 1.10"-1.25" Maybe not that much spacing but if the top and bottom of the hub adapter are making contact then it's tightening down not on your hub but on the hub adapter which equals slipping. Another way is to shave off how ever many millimeters you need so that there is a 2mm gap in between each clamp. Personally, I prefer the 9 bolt rag joint, I believe they're safer then the hub adapters. I just bought a mag wheel so lets hope for the best.
My problem is I put everything together.And these black boats are just so d*** tight.I can't get them out to put a 44 tooth sprout in there.Somehow it's stripped and gripped in all kind of crap any suggestions before I grind them out .😢
I like it I mechanically inclined pretty much anything that's broken you fix it do you guys really think the average Joe what do something like that I highly doubt it but yeah common sense I like it it's sweet as hell
I just installed one of these Hub - sprocket adapters so if I have any issues after the run-in test, I will weld it to the hub because my hub is aluminum and of course the sprocket adaptor is aluminum
Why not use epoxy like jb weld and call it good? It’s a longer wait,but no structure modification and for all that trouble with the spokes just tack weld it at any shop for 20$
I just got a 80 cc 2 stroke motorbikes and not know if its been broke in?? What ratio should I do with gas and oil?? I bought amsoil synthetic dominator racing oil. Says run 50/1 but I'm not Shure. What do I do please.
@@tonytaylor5087 I was Also wondering I let my bike idel for 5 min or so and the motor is hot is that normal?? Its a 80 cc 2 stroke motorized bicycle. And the bts on the head turned a little white ??
Same here. My spokes are 8-way symmetrical, so I it's pretty much impossible to line up the 9 holes of a rag joint or the 3 holes of one of these adapters. I finally mounted the adapter by loosening 2 spokes enough to move them out of the way of the bolt sleeves. I thought about doing something like this, but simply adding a little bit of grit/sand between the adapter halves and the hub before tightening them down should accomplish the same thing. Both surfaces are aluminum, so there shouldn't be any concern about corrosion. I hope @BikeBerryCom sees this and has a suggestion for the spoke problem.
Why don't they come with these issues fixed. It's not like they are cheep. I never had any luck with them. My problem is the sprocket bolts getting loose.
And for the price of those I think that should already be cut out for us.. or why not even talk to the manufacturer and have them put some type of teeth in it so it digs into it when you clamp it down
I'm gonna try 2 small round head bolts threaded into the inside center 1/2 of each adapter piece. Then drill 2 holes in my hub that the bolt heads slide down into....Similar to how wooden dowel pins work in wood working. The 2 bolt heads will act like 2 woodruff keys or 2 dowel pins.
Just installed one of these without any of this work or tools. Cut an old tire tube to wrap the hub circumference. Held in place with a piece of electrical tape. For my instalation it took 3 wraps of innertube cut in half and to circumference each layer. Does not move and takes way less time or effort. Also I did not have to open up the holes in the sprocket. Might have just been luck but man this seems like way too much work and also destroying your wheel his way.
That's an Excellent idea which eliminates all this crazy fabrication. Another guy suggested double sided sandpaper between the adapter and hub. I think your idea is better
Isnt that a coaster brake arm that you keep telling us to make sure it clears the sprocket? Why would you be using coaster brakes on a motor bike in the first place? Isnt that dangerous?
The key is not exactly a precision job without backlash . As the adapter is going through the spokes, the backlash in the key will still rock the adaptor in the spokes and so it is the spokes that will limit the movement and not the hand fitted key. It would have been a better result had the adapter been lock tighter on the hub or else the adapter drilled and a hardened screw threaded in it till it meat a countersunk hole in the hub. As it is the key has too much backlash and it is the spokes alone that will hole the torque.
I don’t think people are going to read the title properly. He’s taking extra steps so the easy adapter DOES NOT move at all. Like problems I’ve been hearing about the easy adapter
Talking about aftermarket motorized-bike parts as-if they are really universal parts, by those selling them is very misleading, or even borderline dishonest, more likely than not, your build will have it's own little problems, and if your not already mechanically-inclined, or at least interested in learning, these problems will seem bigger than they are, if you do manage to get it built, then maintaining it will become a big issue, that's the truth they should be telling people.
Drill a hole all the way through adapter tap it and use a Allen head set screw, put a small dimple in the hub for the screw to set in much easier and faster provided you have tap die set
I agree with you
That’s a better idea
Make a video I'm stupid

If you have aluminum hubs, you could have someone tack weld the hub adapter to the hub after you clamp it on.
Drilling and tapping a hole and using a set screw is a whole lot simpler and accomplishes same.
Interesting option for sure. I’m gonna test that out! Thank you

Need help with. Carb. Choke won't stay tight
So much for plug and play?
Hey J, in my experience it’s hard to have every part be as easy as plug and play. It’s pretty close though. Thank you for watching!
I tried cutting that grove in a bike berry steel rim and ended cutting a hole through it. :(
Why not use epoxy like jb weld and call it good? It’s a longer wait,but no structure modification and for all that trouble with the spokes just tack weld it at any shop for 20$
Hello Wake, yeah, those are definitely options you can do also. Let us know how those work out.
If you have aluminum hubs the aluminum adapter could be tack welded to the hub after it's clamped on.
I just got a 80 cc 2 stroke motorbikes and not know if its been broke in?? What ratio should I do with gas and oil?? I bought amsoil synthetic dominator racing oil. Says run 50/1 but I'm not Shure. What do I do please.
40:1 cradle to grave
@@tonytaylor5087 I was Also wondering I let my bike idel for 5 min or so and the motor is hot is that normal?? Its a 80 cc 2 stroke motorized bicycle. And the bts on the head turned a little white ??
Gostaria de comprar o kit completo poder ser ?
Anyone else having trouble fitting this on there rim? I have a 32 spoke rim with 16 on each side and I can't find a good angle?
👍👍👍👍👍
Where did you get the adapter?
Hi there I run mine on 5o to 1 I’m I wrong thanks.
So I think covering it with tape will work
Hey . My adapter doesn’t fit thru my spokes correctly. Old school American wheel with 1.5 inch hub and adapter… any idea ?
Same here. My spokes are 8-way symmetrical, so I it's pretty much impossible to line up the 9 holes of a rag joint or the 3 holes of one of these adapters. I finally mounted the adapter by loosening 2 spokes enough to move them out of the way of the bolt sleeves.
I thought about doing something like this, but simply adding a little bit of grit/sand between the adapter halves and the hub before tightening them down should accomplish the same thing. Both surfaces are aluminum, so there shouldn't be any concern about corrosion.
I hope @BikeBerryCom sees this and has a suggestion for the spoke problem.
How can you keep it from wiggling
Might be expensive but cant a welder braze the hub adapter onto the hub?
Are these kind of brackets harder on your spokes than the rubber ones??? I'm assuming a yes
Not really. It transfers all the torque to the hub
Why don't they come with these issues fixed. It's not like they are cheep. I never had any luck with them. My problem is the sprocket bolts getting loose.
#builditright #builditcustom one day I plan on getting one to try but honestly I don't mind the rag joint..
I don't mess with them, I've seen enough people destroy their rear wheel using sprocket adapters.
And for the price of those I think that should already be cut out for us.. or why not even talk to the manufacturer and have them put some type of teeth in it so it digs into it when you clamp it down
I'm gonna try 2 small round head bolts threaded into the inside center 1/2 of each adapter piece. Then drill 2 holes in my hub that the bolt heads slide down into....Similar to how wooden dowel pins work in wood working. The 2 bolt heads will act like 2 woodruff keys or 2 dowel pins.
Just installed one of these without any of this work or tools. Cut an old tire tube to wrap the hub circumference. Held in place with a piece of electrical tape. For my instalation it took 3 wraps of innertube cut in half and to circumference each layer. Does not move and takes way less time or effort. Also I did not have to open up the holes in the sprocket. Might have just been luck but man this seems like way too much work and also destroying your wheel his way.
That's an Excellent idea which eliminates all this crazy fabrication. Another guy suggested double sided sandpaper between the adapter and hub. I think your idea is better
CAN YOU USE RED LOCK TIGHT IN STEAD OF KEY
better to use JB weld but that will give away eventually
#BUILDITRIGHT/BUILDITBETTER Thanks Tony Taylor
I won that sprocket si o si
why not just do a locating pin?
Isnt that a coaster brake arm that you keep telling us to make sure it clears the sprocket? Why would you be using coaster brakes on a motor bike in the first place? Isnt that dangerous?
The key is not exactly a precision job without backlash . As the adapter is going through the spokes, the backlash in the key will still rock the adaptor in the spokes and so it is the spokes that will limit the movement and not the hand fitted key.
It would have been a better result had the adapter been lock tighter on the hub or else the adapter drilled and a hardened screw threaded in it till it meat a countersunk hole in the hub. As it is the key has too much backlash and it is the spokes alone that will hole the torque.
Another good quality video! But Hub adapters suck, they're more trouble than they're worth. There are better ways to mount a rear sprocket.
Brother I gotta drill and sand an 80 dollar kit?
#builditright
I have no grinder but I'll drill a hole instead
28 teeth Sprocket for the back
I stripped my Allen wrench screw and drill is definitely not a good keyway
I like you keyway with woodruff thingy
or just weld it on
I don’t think people are going to read the title properly. He’s taking extra steps so the easy adapter DOES NOT move at all. Like problems I’ve been hearing about the easy adapter
strong Gule 😅
Talking about aftermarket motorized-bike parts as-if they are really universal parts, by those selling them is very misleading, or even borderline dishonest, more likely than not, your build will have it's own little problems, and if your not already mechanically-inclined, or at least interested in learning, these problems will seem bigger than they are, if you do manage to get it built, then maintaining it will become a big issue, that's the truth they should be telling people.
it was supposed to be designing for better and ease to install
