That's the 20.2. He's specifically asking about the 20.1, which was sadly 116mm. My originals were 135 so I could run a Hope, but the bosses at Alias felt there would be a larger appeal to 20" riders if they didn't also have to change their hub/back wheel to experiment with a new geometry, so they made the production model 116mm spaced.
My DIY frames and the black prototypes were spaced at 135mm, if they're the videos you watched.
The production 20.1 (dark green and grey) frames were spaced at 116mm. I had a Hope custom modified by a friend to fit this spacing.
The 20.2 is spaced at 135mm, specifically because of so many people wanting to run Hopes.
If you have a 20.1, to run a Hope you will either need:
A talented friend to customise a 135 hub for you (from what he told me, it's doable but not a particularly simple task, especially if you want the disc tabs to still be functional)
To miraculously find one of the handful of hubs that have already been modified (I only know of about 5 that have been done, including mine, and I suspect people will be wanting to hold on to the ones they got done!)
Or find an alternative - a front freewheel setup, or a different freehub that comes in 116mm. I've never investigated other freehubs so I'm afraid I can't advise on likely candidates.
