it appears that most of Alta owners are former Big 6 MX bike owners, not former Zero owners.
Yes, surely - and I guess this kind of colors my perception. Like everyone else prior to early 2017, I really had no choice in the matter: back then it was either ICE or a modified Zero for dirt (which no MX guys would've considered anyway). I'm very grateful for all the riding I got in on the Zero, limited though it is compared to the Alta.
Riders either buy and ride ICE, or buy and ride electric.
I agree totally - but I think these are two separate markets (
for now). The electric actual-MX-bike market in the US has existed only for a little over a year, since Altas started shipping in early 2017. I think most ICE riders don't even know they exist, even today - so they'd never consider them, and if they did most would likely bench-race them out of contention by weight / price / range / sound / smell (ever hang out at ThumperTalk?)
And speaking only for myself, after having actually ridden electric for a while now I'd never consider ICE again, so I'm definitely biased.
Once e-bikes become mainstream - and especially when MC race fans start watching them walk away from the pack from the start gate on - I think everything will change. I don't know what to think about the big guys - with the exception of KTM's playbike, it seems like they're still mostly in mock-up mode (Yamaha anyway):
