So it seems they could source the same hub as Helix mount on their bikes?

Rims in ETRTO507 which is a BMX size aren't a problem, including TL ready rims. S[pokes neither.

The problem is to find 40x507 tires or narrower.

And maybe the rear hub: I read for both the White Industries and Onyx rear hubs that they are "Modified for Helix", what does that mean, what must be modified on a standard rear hub to make it compatible with Helix?
