I calculate ~$7K for battery and motor + controller in volume assuming they use canned cells.
Now plus Ohlins, Brembo, carbon fiber, swingarm, frame, fairings... R&D, staff and two facilities paid for, assembled and QA tested ready to warranty made in small quantities- that's a hell of a deal at $20k. Almost like a backwards early adoption (I dream for XRP) cost.
In the only article that gave any details, around the time of the original PR, Lightning said they're using pouch cells -- and those don't have standard designs.
Homologation also costs a lot of money.
They claimed in at least one interview/article that they can offer the low price for the Strike due to integrated manufacturing in China... But they also announced buying a manufacturing/assembly facility in San Jose, so which is it?
Integrated manufacturing only makes sense for high volumes... But the Strike doesn't have ABS, so they won't be allowed to sell it in Europe, which is half the market.
And they haven't said anything about how they'll handle sales / demo rides / service / warranty work / service training.
And there have been no sightings of prototypes testing anywhere -- surely, as they were supposed to start deliveries this month, they'd have had multiple near-production bikes undergoing stress, reliability and safety tests?
