But never tested for lateral loads so no cornering. This was talked about when designing your test rig as cornering is a Mager part of riding a skateboard.
Was also talked about and you did some slow motion shots showing it but has the testing included this? I’ve only seen the test rig have perpendicular bumps applying a harsh but even load acros the wheel.
Test rigs can only go so fare DIY community puts a lot more demand in there boards then production boards we have bigger motors,ESC,battery’s ride faster and harder just push the boundary’s more the real proof is going to be the revues coming back from the first batch (tho you have mention you have a couple of people putting huge mileage on some wheels) and how any issues are delt with. I have seen more company’s fail from bad CS than the products. Bringing a product to market is so mutch work and easy for us arm chair Warriors to pick up on any thing slightly over looked as we have 1000’s of eyes looking at it from ever angle.
Looking for recommendation of wheel pulleys when you ship as your design is not comparable with any of the pulleys I have for ABEC or Kegal on any of my boards. Reasoning is it wasn’t worth the retooling cost or time even tho it’s been retooled twice sinse.
?? how do you figure lol
He has kegel and abec cores already
Because the design need short pins as the core dose not have the depth for full length. Cheaper pulls generally have shorter pins
What about just cutting down the long ones to size?

You cannot propose this on a diy forum dude.

I would love to, but I am limited on the covers that I got. I have been using the same covers since they never break and just testing the cores.
Sorry to everyone. Been working on the update and doing testing. Sorry for the delay. Update tonight, I promise.

No worries, we are very patient because this is a game changer for sure! Innovation requires time and im sure everyone here is fine with that, although I could be wrong
Yes, I do test for lateral loads, which are the most stressful to the wheel (at least this wheel design) due to the amount of deformation and heat that is generated in the wheel. See this blog post back in April: https://momentum-boards.com/blogs/news/hollow-wheel-manufacturing-and-shipping-update-12
Yes, test rigs only go so far and are great for isolating variables. So I have my bigger friends riding that also like to carve a lot and gathering data for real world. There will be defects and there will be issues along the way when I start shipping; I can’t guarantee there won’t be but I will guarantee that I’ll make it right. Right now I am trying to make it so that I find all the bugs before I release a product that has a lot of warranty claims, which can really hurt and kill the company.
Re: pulleys - if you have one of those pulleys that needs the pins to go straight to the wheel for Kegel, then the cover doesn’t have that. I’ll have more diagrams in my update. With ABEC, they go all the way through - my analysis in pulleys showed there were more pulleys on the market with ABEC and more pulleys in existence with ABEC and thru hole pins (screws). My analysis showed that a high percentage of pulleys don’t go through. Some solutions will be presented in my update very late tonight.
Sorry again for the delay. Just working every moment I can on these. If it is pressing, you can always reach me at hello@momentum-boards.com - I get email pings but not forum pings on my phone.

Could you glass frit a drum then roll them on that till the wheels or the frit won?
I nominate @Sender to make it.

Just use the wheels to drive a belt sander.

hmm, just angle them off parallel axis on a concrete cylinder, if it is also off it’s rotation axis you would get cyclical compression.
The thing that the test rig doesn’t really simulate well is temperature change. You have scrubbing of the wheels which generates a lot of heat and then a lot of temperature fluctuations. Still working on the update. I am dealing with some wheel overheating issues right now so this is a complicated update.

Or long pins like @3DServisas and others that were found not to fit. I don’t use bolts in any of my pulls any more as it can cause the core to fail. So what’s your recommendation for quality pullys (I personally don’t class plastic pulleys like evolve as quality)
Still unsure of how it was done or if it included hitting potholes at angles as I’ve always believed that is the highest stress wheels would be inflicted to and most likely to expose any potential weak points.

Are we certain that Boardnamics ones won’t fit yet?
There is opportunity for @Boardnamics to have a second pin length if he wanted to
It’s extra work but if he’s the only one that supports these wheels out of the box, might be worth it.
As he’s mentioned multiple times, there are people actually riding these and putting miles on them, providing feedback behind the scenes. With the amount he has shown us, I would have to imagine these are more durable than many urethane wheels

I seriously think that there isnt anything more @TheGoodMomentum could be doing. I did have someone in an NYC group tell me that “the project is dead, he hasnt posted updated in months”. I promptly replied with a screenshot of him posting 6 hours before.
Doug, you gotta keep the website blog page updated for the guys that are terrified of the forum

Yeah I completely agree. He’s doing an excellent job. This feels like a hummie hubs situation though, hopefully we get the wheels before the end of the year lol
It feels like a kickstarter more than a preorder

I love imagining people scared of us, gave me a chuckle.

Think: Local kid who works for a famous boutique board builder in NYC. Knows more than 95% of the local group. I think not being the most knowledgeable person in the room bothers him.

Lmao that’s great. “I know it all, so I don’t have a use for it”
That’s cute buddy, our combined 100 active regulars can definitely put you through the ringer
