Kindernay observations and few questions for Pushkar

While perusing the Kindernay website, I noticed that they talk about a break-in period for the Kindernay hub. According to their website, they recomend you do an oil change after the first 500km to flush out any particles, etc. from break-in, and then oil changes basically every 5000km after that.
So basically we are looking at a bare minimum of 2 oil changes for our first year of ownership, and for a lot of us, even more than that.
I see on the Kindernay website, they have 3 kits available for sale. A single oil change kit, a 3 pack, and a five pack are listed.

So my first question is:
Will these oil change kits be made on the Wattwagon website, and what’s the price for such kits?

My second question pertains to the Kindernay wheel build.
Will there be an option to purchase an additional wheel build with Kindernay flange, to easily facilitate a wheel swap for different seasons, terrain, etc........, and what’s the pricing for the wheel, including both aluminum and carbon options?

My third question is in regard to tire size.
I see Wattwagons offer both a 2.4 inch tire/rim combo, and a 3.0 inch tire/rim combo.
What is the minimum and maximum tire size recommended for each of these available rim sizes?
Example: Can you fit a 2.6 inch tire on a 2.4 inch rim, or a 2.8inch tire on a 3.0 inch rim? As an original founder, I’m trying to figure out what my options are.

Thanks in advance!
 
1. Kindernay uses regular mineral oil. You can buy it in bulk and be ok with that. I can check with Kindernay and provide some brands that will work.
2. Yes we will provide additional wheel builds. Waiting for pricing from Kindernay for standalone shells before we can do that.
3. The rims are 35-37mm, and they will take a up to a 2.8 inch tire, and 3 inch with the focus of a ninja. Note that 3 inch recommended is 40mm.
 
I finally found the torque limit for the Kindernay on their website, it is 160 nm. That beats Rohloff in torque capability, making it the right IGH for the Bafang Ultra.
 
Yes, unofficially we are able to put ~3500W through kindernay. If geared right, they are probably the strongest we have seen for hubs.
Hey Pushkar, Did you happen to catch the post by one of the 'Bikonit' type but generic bikes guys where his Kindernay fell apart while he was riding it? Something about bolts with locknuts that 'unlocked' themselves? Ever heard of such a thing?

That's sturmey archer 5 speed IMO.

Does that mean you could go unrestricted on the throttle with warranty ?
 
IMO, based on everything we have seen so far, there is a limit on cassettes and hubs both - right around 200 - 220Nm.

From a warranty perspective, we will still recommend limiting the throttle to be around 90-100Nm on our bikes.

Anyone know what kind of mineral oil to use? I received a Watt Wagon bike (the UC Commuter Pro, it's an amazing bike and I'll review it after a few more rides) with a Kindernay and I will get to the break in oil change in a few weeks. I just don't want to muck up the IGH with the wrong oil.

How about this: https://www.grainger.com/product/MAG-1-Mineral-Hydraulic-Oil-49EP02

This one is a more expensive version of above: https://www.grainger.com/product/MO...=AZIDPRR_RRAD-051820&analytics=recommendation

This one is slightly thicker (22 weight) but at least has a red color similar to what Kindernay sells: https://www.grainger.com/product/MYSTIK-Mineral-Hydraulic-Oil-33MF06

It would be great if the royal blood oil that is used with the Magura brakes would work for it too. I am 99% sure that it is mineral oil. Then one oil for both.
 
And is the hydraulic shifter fluid the same mineral oil as the gear oil?

IIRC, everything is some composition of mineral oil. Some have specific additives to reduce viscosity (Rohloff has something like that for winter riding), some have colors and non-corrosive additives.

Right, but if the compositions are different, we shouldn't be using them interchangeably. Or, perhaps it's all marketing.
