Ann, I think your math is a little off but your methodology is sound.
Probably more like 7000 +/- bikes (the 12k figure on the IGG site represents every single transaction including those that spent $1 to endlessly bicker about it on there to little or no obvious effect) and a bunch of extra batteries. It is at $5.5 mil so 500k to A2.0 and 4% to IGG is 220k leaves Sondors with 4.8+/- to be able to deliver the bikes and extra batteries. Not sure how many extra batteries there are but even taking them out of the equation the cost of each bike delivered would be roughly $683. So there is room for profit to be made due to the total number of units even if he only makes $50/unit but that all depends on his cost per unit which figure we will probably never be privy to.
The problem I have is that he is potentially dumping 7000 cheap as possible e bikes into the e bike market that will leave some happy to have and I predict the bulk not quite as much. And regardless of aftermarket support you know it is going to be hard to manage on that large of a scale.

Legal fees, just this single action will be $25,000 or more.

Frankly, there does not seem to be the capacity to address the above business concerns.
Is this fraud of bad business?
At the least it is a consumer pump and dump as all the above issues and concerns are as of yet ignored. However, ethically, A very strong case can be made and argued for false adverting both against Storm and Agency 2.0.
With Storm, There is now a track record of civil fraud for non-payment both proven and now alleged.
The consumer is just too feckless to ask any questions.
My suggestion is that purchasers of this bike ask for a refund.
