So, do I have a "no win" situation?

Well, never one to loose like Captain Kirk, I know I can change the rules, and could custom machine what I want, but hoping someone has an easier solve!

I'm using a motorcycle engine Honda Z-50 for my Moto conversion on a rigid 29er mt bike, and it will be use for "trials" type riding rather than blasting up & down hills! I don't want suspension on this.

I need a rear hub that has will follow these parameters:

An interface that will accept a moto sprocket on the left.
It has to have an interface for a regular MTB chain sprocket on the right.
Fit in between 135mm chain stays,
32 hole spoke pattern
No brake necessary as I will use the stock V-brake.

I don't feel the bolt on or through spoke rear conversions will work a this is going to be flogged off road very heavily, I might be wrong!

I have looked at using a MTB disc brake hub and using the 6 bolt disc mounting area to mount the rear sprocket, but the diameter and small bolts just look to be to wimpy considering it will be turning a huge 29er rim and tire under power of a motorcycle motor. I could drill through and bolt through, but still think it to be inferior.

Does anyone make a hub to fit my situation?

MTB Moto... Thanks
