I was in the process of building a 212cc predator powered bike and wanted some opinions on what kind of wheel to use

I NEED JUST A BACK WHEEL to clarify

Already have the front double wall disc brake wheel

I know I would like to have something with a double wall rim 26x2.125 that's silver 11-13 gauge spokes

I don't want to run pedals because it would be something else to have to modify to fit that huge motor

I can run pedals if required but it has to be a single speed freewheel if that's the case

Can I use a front wheel on the back?



Another question. Anyone know of what kit to use that comes with transmission, gas tank, the sprocket... Etc

If love to have BB's kit but they are sold out.
Can anyone point me in the right direction of where to go???

Okay just for discussion purposes..
My dream rear wheel is to get a Halo SAS 559 x 36mm 48h alloy rim with steel eyelets, built into a classic (old) Hope Big Un 135mm 48h downhill hub that I've been keeping for something special for about the last fifteen years.
The largest rim you can (conservatively) use on a 2.1" tyre is 38mm (internal rim width X 1.4 = minimum tyre width). The smallest (conservatively) would be 27mm. I think you'd need a special specific reason to go outside conservative limits, as with tyre pressure.
The Halo rims might not be available in USA but it is a nice example. Halo do make complete wheels but their own brand hub's are supposed to not last as well as the Hope stuff. Still, they are strong and built to take a lot of torque from a disc brake.
Halo Spin Doctor hubs are available in 48h with 10x135mm solid (nutted) axle and have "outboard" bearings to take the huge side loads of downhill, dirt jumping and loaded tandem touring.
You can use a single speed conversion on a freehub/ cassette hub.
I'm not sure the guage of spokes is as important as the quality of the spoke, suitable lacing pattern and build quality, personally. I trust DT Swiss and a local professional wheel builder.
Which frame are you using and what is the rear dropouts width? Is it standard mountain bike 135mm or bmx 110mm? Though 100mm is the front hub width on mountain bike wheels, they have 9mm/15mm (or 20mm X 110mm) axles and that will not work with 10mm X 110mm rear dropouts. I don't imagine your front disc brake hub has 9mm solid nutted axle...

I'm not sure of sizes and millimeters are Greek to me..... I get the gist of what your saying though, thanks for the help

I know a little about tandam wheels
(I mainly stick to old stuff.... Easier to keep up with sizes, also the reason why I stay away from Schwinn:p)
I built a 78' Schwinn heavy duti once and it had some crazy thick spokes about like a 11-12g. I couldn't find any extra spokes to fit it so I took it too a bike shop and they thought I was crazy for buying a bike that was so heavy..... Until I told them I was building a MB...... If good spokes are better than thicker spokes, what do you recommend? I don't really want to build a wheel because I've seen that done before and I'm not a real patient person;)
I would like to get a price from local bike shops to see what it would set me back but before I can go I need to know what hub, what rim, what spokes...... My shop charges 45$ for wheel building so I'd like to stay away if I can



Here's my bike that the wheels going on, it's a 50ish JC Higgins..... I've heard good things about JC bikes from the era so I decided to give it the best (or worst whichever you prefer;)) welcome to MB'ing:D
