Hello @I_keeps_it_real @Electrotechnics, I am Doug, the designer and manufacturer for the Hollow Wheels. Thanks so much for posting up.
No, I am not the same as momentumboards.com, I am not affiliated or anyone that is connected with my company is not affiliated with that other company. We have a trademark on that copy and so they will need to change.
I have been developing these wheels for 2 years and really accelerating the pace this half past year. The Wheels as pictured are made from 3D printed molds and then I cast in cold-pour urethane into the molds. The materials are strong and have the characteristics I needed to dial in the geometry to create a really comfortable and really grippy street wheel. I used 3D printed molds so I could rapidly iterate, a mold change per week is the fastest I was doing for a while. As such, you’ll see 3D printed layer lines.
Why the lack of reviews? - It takes us 4 days to cast a set of wheels. So I haven’t been able to get the wheels out to influencers. However, I do have a lot of reviews from beta testers, of which you can see below - and with links as validity.
Yes, for a while, I had a count down timer because I was selling the wheels and testing the market. I did put in that count down timer to analyze the impact of the count down timer on sales conversion rate. It did not make any difference so I took it off.
Next step - Injection Molding: These are going into full production to get the very best urethane and use the most reliable and repeatable manufacturing process. I already paid the tooling. I think I am now $20k invested into this project. So if you find this project interesting, please ask any questions. Happy to answer any questions that you may have.
Here is a cool video that compares all the popular street wheels on the market to my design. I rented a $6k slomotion camera, did some testing and here you can see exactly how my wheels perform inside a corner and over pot holes: https://www.youtube.com/watch?v=kdMgsfaJH8w&t

You can find reviews by multiple people, multiple very respected members of the commuter, like Kevin Graehl and Sawyer Reynolds, founder of the LA area ESK8 community, and many more.
Sawyer “One of best wheels I have ever ridden” - https://www.facebook.com/groups/LaAreaEsk8/permalink/664404450839558/
Kevin, “I’ve been testing these. Pretty fucking amazing.”- https://www.facebook.com/groups/BoostedLA/permalink/1271663639831665/
Vincent, founder of Verreal Board Owners - “they handle as good as 110s on bumps but way softer ride and lighter weight. If you’re using 110s or 120s for bumps, these will chew em up” (scroll down the post): https://www.facebook.com/groups/318356599145216/permalink/400656620915213/
