help sizing for sprocket adapter

Hey there, for your situation I think the best option would be a Manic Mechanic sprocket adapter (which I think are the same ones that Bike Berry sells they just put it under their own brand name).

Now the adapters themselves only fit 1.520"-1.528" hubs, BUT they sell custom shims. These shims come in a ton of sizes, including 1.109" and 0.687". Those are pretty clsoe to your dimensions, I'm not sure if they would work though. I think you may be able to email them and ask for a custom shim.

Hello, i'm trying to order a sprocket adapter assembly and the minimum diameter size available is 1 inch. The problem is every wheel I can find has an axle diameter of about 10mm. Can somebody tell me what i'm doing wrong please?

Thanks, can you recommend a wheel that's ideal for the job by any chance please?

Rich, you need to tell us if you are using a coaster brake or multi-speed rear wheel.

I have no wheel yet, hence my question.

Chris & Tom - sorry for Hijacking the thread. Fix if it should be please.

To Rich,

Above are laced with 12g spokes and I find them lighter with sufficient strength compared to 11g. which are slightly heavier. The Shimano Coaster brake is premium compared to the KTM brand, but more reliable. 10 bucks or so more.
There are many other options. Husky builds the best for the money in my opinion. If you go this route using a coaster brake rear and a drum front you will not be sorry. The Standard adapter on the shimano coaster brake cannot be beat for simplicity and reliability.
Before ordering the adapter found here

Be sure it is the correct size and call the vendor to confirm it will fit your chosen wheel/hub. Others will chime in with their suggestions. For me and my riding Coaster brake rear and front drum can't be beat. For tips concerning chain fitting can be found here-

Good Luck and be safe!

So, 12g is slightly heavier than 11g. Thanks, I live in England, to buy and ship those wheels with tubes and tyres would cost more than the entire engine kit & bike frame!

Sorry could not help further. If your Location said Plymouth U.K. I would have known. also "12g spokes are lighter with sufficient strength compared to 11g" (which are larger in diam heavier). . No - 11gauge is heavier than 12 here in U.S.

So you know i'm in the u.k, you've advised I purchase some wheels for the same price as a second - hand car. I'm more confused than i was in the first place.

I retract my attempt to assist. Start a Thread here http://motorbicycling.com/forumdisplay.php?f=53.
I advise to include U.K in the location below your join date Good Day!

There's nothing wrong with the stock rag joint if set up properly. Got a couple of thousand miles on mine with the odd removal and replacement to fix spokes etc.

The intrepid Ludwig may be able to help with sourcing wheels in the UK.

So you live in a Plymouth? I lived in a Chevrolet once.

Got a couple of thousand miles on mine with the odd removal and replacement to fix spokes etc.
That's about right. Typical bicycle wheels are laced with 14g spokes. Rag Joint will work fine up to a couple thou miles (as you say and I agree). Then spokes begin to fail. Pop one, replace it then another goes pop shortly after. Then another, then another. Twisting back and forth back and forth. You are only using 18 spokes out of 36 - a cycle of continual replacement. 14g is too light with a rag joint if you are serious about trouble free drive line reliability. You will be troubled with a wheel of any hub laced with 14g spokes. You must use a sprocket adapter fastened at the hub using the strength of all 36 spokes with 14g spokes, then you can expect a little more life from the wheel. Most multi speed and inexpensive coaster brake rears are laced with 14g. NOT intended to be motor driven. With that in mind and reliability of primary concern - avoid any rear wheel, of any type with 14g spokes if you are expecting a rag joint set up to be trouble free beyond a season. Simply cannot tolerate the constant acceleration and deceleration over time. I KNOW using a hub adapter on a Shimano Coaster Brake with 12g spokes will out last a multi speed hub RAG Joint mounted sprocket on 18 14g spokes by YEARS.
I must also confess - my bike is primary transportation for me. 150 mi per week min to work and home every weekday. If you ride just for pleasure 10 or 20 mi a week, your riding season will be far less demanding. Reliability not so much an issue. Go ahead and use the rag joint. My 2 cents and my 5 years building/riding experience tells me this.

So, as previously stated i'm trying to order a sprocket adapter assembly, I live in the U.K, surely there must be a wheel ideal for the adapter and disc brake. Please help with my question. Thanks.

My opinion on my purchase of a sprocket hub adapter....It's the best money I've spent on something for my motor bicycle. I got tired of replacing spokes or buying new rims. It cost me $92 Cdn but well worth it. I used a digital caliper to measure my hub as recommended by a few folks here on the forum.

Which wheel do you use please?

If you are looking for a sprocket adapter that will fit a mountain bike hub that has a smaller diameter hub than that of a cruiser with a coaster break, livefastmotors sells one that will fit a 1.2" diameter (3.75" circumference) hubs often found on mountain bike rear hubs. Also, the small ones come with shims so you can use them on even smaller diameter hubs. They also make one for a cruiser coaster break hub as well. They are 9 hole sprocket adapters and you can get cheap sprockets in different #s of teeth that will fit them on e-bay from boy-go-fast and others. They are only good on hubs with 36 spokes. They are $65.

I am looking for a wheel that suits the adapter assembly, not an adapter that will suit y wheel. I have no wheel, this is the point of my question. Also, the first 2 links lead to nothing & the third is a link to some random parts sold on e-bay.???? I'm looking for a wheel, surely somebody can help me please.

I'm sorry about the links
