Dually wheels

[Lowlife Lucas]

I'm curious as to how everyone is doing them? I know you need two good wheels, but how do you spoke them and keep them together?
Like this one incase anyone needs to know what I'm talking about

 

[highship]

here's one way...

I have been working on doing something like this and have devised a couple of ways it might work
However i don't know how the one in the picture was done because i cant see the tube valves

*both ways will require a wider than standard hub*

1st way - line up valve holes then weld the 2 rims together on the inside (area where tubes are placed) at the point
where 2 lips meet and use a 2 separate tubes to air up the tire

2nd way - line up valve holes and wither weld rims together on both inner and outer section where the 2 lips meet or
instead of welding attach both rims using JB Weld
after rims are welded together grind down middle lip (section where it was welded) either 1/2 or 3/4 way down
once desired amount is ground down use a filler (bondo or spray foam) and sand down the filler so that it is
even with the middle lip (may need to sand out extra at the two outer lips to help tire to seat)
then drill out the filler at ALL holes where the spokes where
remember to drill a hole in the middle of the two valve holes for the new larger tubes valve stem

Another variation on this that i want to try (which is technically more of a true dually wheel setup)
line up the wheels at the valve stem hole
make a spacer ring (it will go in between the 2 rims)
weld the 2 rims and spacer ring all together inside and outside
lace up as you would a single wheel
then you should be able to run 2 tires and tubes as one
(great for doing a mad max or vintage dragster style bicycle)

check out the beyond thumderdome build. . .there are some interesting ones on it.

That thread by 1HorsePower that Highship mentioned is pretty good, it would be a good way to do it.
If you need a wider hub I did a how to on widening a standard freewheel hub and welding it to car rim, it is split into two sections though, you can use the first half for building a wide hub for normal spoked rims, it can be found here: viewtopic.php?f=3&t=68533&p=661483#p661483

This sounds awesome! Would love to give that a go! 8)

Yeah that beyond thunderdome link was excellent and i loved his dually setup but the one I had mentioned (that required the spacer) was if you wanted to use standard balloon tires for a really wide look
I was going to do that setup on a bike using 2 sulkey slick tires in the rear

 

[dragnusa]

Could you use the rear hub from a occ chopper for a dually rim

 

[MONARKofSoCal]

Should be able to use an occ stingray hub as long as the width of both wheels together is roughly about the same width as the occ rim (4"/100mm) for smaller width rims anything in between (4"/100mm - 2.25"/57mm) you may have to use an aftermarket hub

Here is how I have done my first attempt at widening a wheel for the "muscle-bike-build-off"...
viewtopic.php?f=43&t=68143&st=0&sk=t&sd=a&start=240#p672007

Didn't know it was called a "dually" but that makes sense :roll:

I just drilled a wee hole between every third spoke hole for a pop rivet, then cut wee pieces of metal strapping that already had holes in to strap the two rims together using pop rivets.

I got the front and rear wheels from a donor bike and removed the spokes and hub from the front leaving the rim only. With the back wheel, I removed all the spoke nipples leaving the spokes and hub attached to each other (I don't have the tools for removing the rear cassette assembly).

After pop riveting the two rims together with the metal straps, I simply refitted the hub/spoke assembly and tightened it up. It was my first attempt at truing a wheel and it still has a slight wobble, but after inspection, I noticed that the axle is a bit bent But I am happy with how it is at the moment

I have used two 26 x 2.125 tubes in it and so far only inflated them to 10psi each. Hopefully it will all work out and it will ride ok and the chain will not hit the tyre...

I did this years ago and all I did was weld the two rims together from the inside. Ground down the welds then I took some thick friction tape and put over the welds as a buffer...... Laced the now wide rim on the original hub and put two inter tubes in it. The only thing I didn't like, every other nipple hole was empty and I had planned to run a 72 hole hub but never got around to it. The chain would scuff the edge of the rim every so often but I didn't mind it. I put literally hundreds of miles on this rear wheel without a problem. I did it back before anyone offered the wide wheels and this was the only option but it worked good for me.

Here's a oober technical way to do it that requires no welding but a little bit of drilling

And I remember rrd build off 6 goldstreetcustoms built a bike called wiseguy and it had a duel rear hub I bet if you flip threw the old posts you'll find the build
