Wow! That’s fascinating... a bit depressing... but good to know

It would be interesting to see how it may have played out without mistakes. Ty got off course in The Woods and that may be why he ran out of juice before the planned battery switch at checkpoint 11, The Machine.
I assume there must have been two battery changes planned as The Machine is a little less than half way along the course with Carl's Dinner (the rocky section), Grüne Hölle' or 'Green Hell'', and several difficult climbs yet to come. (if you watch the Red Bell video above they show the course with a box to the right that shows distance and elevation.)
Very impressive for a battery bike given where the technology was only a couple of years ago. If you want to see what an Alta can do on a single charge you can follow along with this rider. Ty rode the Alta close to The Machine, checkpoint 11, which is the first 48 minutes of the video. To be honest, I would run out of energy before the bike did on this course.
I doubt the bike was being ridden on the full power mode as it would be supercross type power. Totally inappropriate for gnarly terrain. Most likely was being ridden in mode 1 or 3 for best power delivery for the conditions.
I shoulda said more clearly "on full power mode before it kicks over to low power mode". My understanding is that the bike knows when it is getting low on charge and then switches over to a 'low output' mode that gets you back to the truck before the battery is 100% depleted.
I still haven't seen any stats from Alta from Erzburg, so I have no choice but to put off my purchase plans until next year. I was ready to sell the 2 smokes and learn to trust electric THIS year. Dangit!
I would sell all my bikes today for the alta even with the range limitations, if I knew that battery upgrades could be retrofitted in the future. Does anyone know if that’s the case?
I would love to know this as well. The EXR has all the parts to stay relevant / make it last but not being able to keep up with the new tech would be a terrible investment at this juncture of electric bikes.
Battery upgrade is the whole deal in this. When my leaf get 200kwh...yay
I was told that the entire battery pack can be swapped in about 20 minutes or less. The design looks very modular. If you follow any EV forums or electric bike kit threads you would see how many creative solutions are available for battery packaging and BMS (manage charge of various voltage combinations).
I'm confident that there will be an aftermarket industry, just like there is now with slip on exhausts and such accessories, that will match connectors and voltage and offer more power and range in a smaller lighter package when the battery tech inevitably improves.
Don't let range anxiety stop you from enjoying the ride now, today.
No one outside of Alta could answer that with certainty. If Alta keeps future batteries to the same relative form factor, it should be no sweat as a relative "bolt-in" upgrade. The way Alta has built the chassis and engine cradle, it does look very modular.
But as others pointed out, a battery is a battery is a battery. As long as it fits in the space and is the correct voltage and supports the required current, it could be made to work... Aftermarket potential is significant when battery vehicles really take off. Expect stock replacement type items, as well as performance upgrade parts, and even budget-based, just-keep-it-running parts for future EV's.
I like this thinking...except for me with today's battery capacity, my range anxiety would quickly turn into sore feet from walking in motorcycle boots. I still want one anyway (though I don't think I'll ever justify it until it can "go the distance").
Edit: for me, I think I'm just an incremental battery capacity increase away from making it workable. If it could get me to work and back on a charge (roughly 75 miles round trip, at about a 60 mph average speed), I might be able to justify the cost and modify my recreational riding to suit the bike's range.
