spinning the idea a bit more...and how about a planetary gear set inside the drum?
That would give the space and possibility for a low gear range of a 3/1 reduction for to climb trees...
without breaking the final drive...=> obviously the sidecar drive would need another approach.

You could always put a planetary in the sidecar hub too.
Scratch that. I don't know enough about the 2WD to know where the drive shaft gets it's rpm.

Who'd have thought a good idea from me and Chad's smarta$$ comments. :lol: :lol:
Instead of rotor you can add sprocket for crawling low gear.
Not sure how to accomplish that, but you could use the sprocket and another wheel/sprocket to build a tandem drive. If another drive tire isn’t enough traction, one could always stretch a rubber track over the tandem.
Steering it is another issue.

Happy trails,

So you can have a brake disc one one side and a brake drum on the other, all on one hub! Dual technology "Drumisc" braking! Maximum stopping force! That's outside the box thinking. WAYYY outside the box! :lol:
Put a carb bike FD on an EFI and use the drum as a parking brake, EFI parking brake problems solved.
Now that's a genius!
IMWA actually tried that setup for the parking brake. I don't recall why they didn't use it. I do remember they used a big honking lever from a pickup truck.

Brake shoes will not fit inside efi hub without machineing and it it also tapered surface.

What I was referring to was a prototype that came before the production EFI hub and FD. If I recall correctly, it was just the standard drum setup with a disc added.

I had a picture of it, but cant find it now.

Here's another prototype hub that came between them that was universal, and fit in all 3 positions. Again I don't recall why it wasn't used.

Van, if you haven't actually applied for a patent yet you'd better get jumping on it. The U.S. is a "first to file" country now. You have one year to file after first disclosing the idea publicly. After one year ... you cannot file for a patent.

Someone ripping off your idea does not make them the "inventor", only the actual inventor can file for a patent. But the onus will be on you to provide documentation that you actually ARE the inventor; dated drawings, prototypes, etc. Much easier, and safer, to take care of all the patent stuff ahead on disclosure.

In my experience patents are only good if you have the resources to defend them.

True.
It is not cheap to copy.
That hub is cast new and machine not modified from existing ome hub.
Ural is small community.
Chinese are not

See the different in casting?
Now if you can do all that and sell less than $300
Go for it
Just bearings and bolt on spline will set you back $150

BTW.
With advice from my Pattern attorney.
Hub had warning label
"For off road use only do not exceed 15mph"

Van, I love the concept. One of the reasons I chose my older bike was wheel interchangeability. So far I've managed to survive Drum brake machines.
Can't say the same of DISCs - As I had one grab & lock at speed that totaled my Kaw W650, my only crash in 50 years.

The "OFF ROAD USE ONLY" warning label doesn't sound like it will be helpful to the venture. Can that be changed after testing completely ?
But then, my Headlight reflector insert was "off road only", & my new Mikuni Carbs are for "off road & racing only".

I sure do. enjoy seeing your creative innovations & improvements
