I agree, us vet guys can get a full moto at what we consider "full power". However, when any builder states or implies that their bike (or planned bike) is/will be competitive with the current crop of MX gas bikes without qualification (like saying race competitive for most vets and C/B riders under average track conditions like the Alta) I gotta call BS because it just isn't possible right now. For example, a stock KTM250SX can race and be competitive at every level and at any MX/SX track in America. An electric equivalent is years away. That's not to say it couldn't be done today, however. With an unlimited budget and laboratory level battery technology it's probably possible, but who's got that kind of resources and desire, maybe Musk or Bezos.Riders who expect longer than two hours from their batteries should not be poo-pooing the bike and the current battery technology. For those of use who ride at motocross tracks, 30-40 minutes at full power is plenty. And 2 hours of trail riding is also long enough for me.
To be fair, the FLUX guy did stipitate "Performance much like the Alta" so if that's the goal I don't see why it can't be done again. My Yamaha 125 conversion came close, was about 245Lbs and had liquid cooled motor, inverter and battery pack. Too bad the DHX Hawk motor decided to fail 8 months ago as I'm still waiting on the replacement.
