Why? Original AT wheels are 8 x 2inch, hub inside width is on only 31mm wide! The truck hangers are also narrow relative to the power and length of the board. In my opinion this is the only area the board is let down. I was going to sell it but then decided to fix the issue by designing some super wide hubs.
I designed an outer Deep-dish hub that can connect to the existing inner hub.
Total increase tyre width to take 2.5" or 3" inch wide tyres at 8"" diameter and not sacrifice top speed by using smaller fat tyres. This hub matches to the one-off wheels that 3D servisas made for the plutonium 1 All Terrain boards The new outer hub is 50mm wide so the total hub width is now 70mm. That makes them 5 mm wider than the Kaly Hellcat Wide wheels which take the 8 x 3 inch tyres. But these wheels are 30% lighter than the hellcats.
Uses all the existing bearings 8 x 22 x 7 608’s , spacers and bolts, no changes except for needing wider tyres. These bearing are quality NSK’s and design for very high loads. I would not use this design with any other bearings. The wheel also has a third bearing on the idler gear which is bolted to the wheel. This additional huge bearing supports the loads very well.
My next step is to get this prototype CNC’d 7075 Aluminum I will be ordering in the new year.
Yes, it is possible these hubs will place a higher load on the bearing, but that is needed to increase stability. The fact of matter is the original design does not place enough load on the bearings and they are rated to handle much higher loads. The original 8mm axles unfortunately mean to upgrade the plutonium 1 to 10 or even 12mm requires a completely new drive train and then you still need to get wider wheels, so wasteful and crazy expensive as in $2500+. The plutonium 2 parts do not crossover as Bioboards started manufacturing their own stuff with new design. So, I believe this is the only way to get the Plutonium 1 AT up to current standard for high performance boards and is likely the cheapest possible way to do it if we can get an order of 20 or more hubs made.
The design is simplified with the 5 holes ( access the gear drive bolts) and heavy duty to account for the extreme width and cantilevered flange design of the existing wheels. So, there is more meat in the inside which where those grooves are cut out of. The slot for the valve is extended and is almost the same as the Kaly Hellcat Wide design which i also have a spare wheel and I used to get some reference points off for the valve stem.
Here is my design, I am looking to see who may want to upgrade their wheels as the CNC costs are affordable at higher quantities, if anyone has a plutonium 1 with the AT wheels and you want to add a ton more grip, stability and width I would be happy to register the interest and provide updates on this process.
I added the locating blocks on the rear of the hub to enhance the finished assembly.
