Hi Fat6,
You would have gotten more views of this post had you posted it in the Haibike forum page. Anyways, give a call to Old Man Mountain Products and tell them what you've got.
I have a Full FatSix myself and am readying to get funding together to purchase a rear rack for the bike. I have the Old Man Mountain Fat Sherpa front rack installed on my bike and it has been great. Plans are to get the rear Fat Sherpa rack for the bike.
I am not positive, but I believe your rear triangle dimensions are the same as mine, as in being 197mm x M12xP1.75 axle. But double check the specs page in Courts review and test of the FatSix, located on this site to confirm the dimensions. You need them to ensure the correct Robert Axle Project rear axle is provided and/or available for the FatSix.
The OMM rack has it's full weight on the axle (very desirable) and the rack is stablized with aluminum stays that will connect to the rear triangle downtubes via rubber insulated clamps. Here's a pic of my Full FatSix front rack made for the Bluto. I replaced the plain steel hardware supplied by OMM with marine grade stainless steel, including those clamps, nuts and screws. I had the bottom brackets and support struts professionally powder coated.
Come on over to the Haibike forum and post up some pics. I like that FatSix, based on Court's review.

Hi Joel,
That's a nice looking rack, the Axiom. Unfortunately it does not appear that it has a thru-axle compatible lower leg bracket made for it; after looking at their website and a trusted, large online bike shop that sells all of their products. After getting my Full FatSix, I was determined to go for the Surly Nice Rear racks; racks that I had installed earlier on my Specialized Fatboy onto this new Haibike. I was new to all of this thru-axle business, the Fatboy being a quick release skewer set up as well as having threaded riv nuts in the lower stays that allowed attaching the lower leg stanchions of the Surly Nice rack. After looking at every available rack on the market and knowing I did not want to jury rig an attaching point that may or may not hold up under the weight of gear on the rack, I ran across the OMM set up via the MTBR website.
I got to thinking what it would take to use the Fatliner rack in conjunction with the purpose built Robert Axle Project thru axle for our bikes along with the OMM leg mounts that attach to this axle..... And a look on the website shows these individual pieces are not available; it all comes in a complete rack/brackets/thru axle package. Oh well, sigh... Even the Robert Axle Project says OMM is the only thru axle game on the market. https://robertaxleproject.com/cargo-racks/
Joel, I write this not because I have any interest in OMM; I have none. It's written as a person who has gone down the road you are about to go down and just want to save you the time, money and aggravation that awaits. The real issue for us rack types is that the bicycle manufacturers have done a poor job in providing mounts built into the frame to accept the simple 5mm cap screws that hold down 99.99% of the racks out there on the market. And it's very important from a safety factor that the rack is secure on the bike; that it can hold the weight we put on it and the hardware that holds it all together can take the load!
Best Regards,
Mike

Hi Joel,Mike,
I really appreciate your detailed information, you obviously are very thorough when you approach a project. I agree completely that a axle mounted rack is the way to go. I chose to take this route do to running out of time. I will review the link you attached.
Changing the subject a little, I see you have logged 5000 miles on your bike. Just curious if you had to replace the battery or any other failures with your bike?
Thanks,
Joel
Hi Myke,
I had zero luck communicating with Channing Hammond of OMM, so I kept a close eye on Ebay and was able to find a Phat Sherpa that fit a Salsa Mukluk. Lucky for me, I had a pair of extra lower legs that he had sent me in a snafu involving my purchase of the front rack from him that was fitted for the Bluto fork.
After talking with the Robert Axle Project folks, they advised me as to what rear thru axle I needed for the 197mm Haibike rear. Little bit of powder coating; replacing the OMM plain steel parts for stainless and I was in business. The finished rack project, front and rear is pictured below.....
Another idea would be to have a weld shop fabricate 4 lower rack mount legs, using your Outfitter parts as templates out of 5/16 or 3/8 inch thick aluminum. Axles could be procured via Robert Axle Project. Note: if you are running a Bluto or RST fork on your Haibike; you'd have to find that Robert Axle made for the Bluto; a bit different then the rear in how the front lower legs attach to the axle. If you need them to understand what I'm referring to, let me know. I can take some photos of how the front rack is attached to that front axle and get them posted here in a day or so.....
Where did you get the clamps for the front forks and the rear frame rails? BTW SWEET BIKE!!
Mike, What bag is that on the front?
Good shout, I’ll do that, Thanks for your reply, I can ask about shipping to the uk at the same time!I suggest you email OMM with any questions, they will get back to you right away and the customer service is excellent now that they are under new ownership. I also have the OMM rack and it is extremely well designed. I take it over bumpy trails and it holds fine.
I would suggest you follow the instructions in the manual and routinely check that all the bolts are torqued to spec.
