I hope so. They are the first to take it all the way and deserve to remain a force in the market.
Definitely the first to take it all the way in terms of a viable off-road / MX option on the same or better level of performance as ICE bikes (with some caveats), and
much better off-road execution than Zero and others. However, as I'm sure we all know, the market doesn't owe Alta anything. Good news is, they make an incredible product, have sizable demand, and have loyal, evangelist type of customers. No idea on their total sales and key financials, but have to believe they're exceeding expectations.
They've definitely benefitted from coming at this from a dirt-first approach, and while they may branch out into more urban / street (supermoto aside), I just don't see any immediate competition from any of the other brands in the off-road area. However, as soon as there are changes to how the AMA / FIM treat electric in SX and MX, I'm sure we'll see some big moves from the big guns (keeping my eye on Yamaha; the first of the production MX 4Ts).
Hopefully Alta will keep attracting, motivating, and retaining top talent and have the support and patience of their board / investors. They've only been in production for a couple of years, and launching a new vehicle brand is so difficult, especially for mostly hobby / enthusiast vehicles.
EBR knows how hard it is,
as does Motus motorcycles.
