I'm looking at https://beeline.co/pages/beeline-cycling for example, but it isn't clear what display they're using, it looks like regular LCD, not even anti-glare? What's nice with e-Ink, is that it's highly visible even in strong sunlight (extra so when they've focused on anti-glare), while LCD even with anti-glare can be difficult to see.

While not e-Ink, I had the impression that the Beeline has more outdoors-suitable displays. From the Beeline Moto 2 specs:

"Technology: Ultra bright IPS TFT with anti-reflective and hydrophobic coating"

But e-Ink would be superior for outdoors readability. I was looking for a motorcycle navigator when I found the OP article.
