is definitely a week point and I would worry to break down the enclosure when going off-road.
It’s common practice to adjust the springs from the up, just look the trampa boards.
It’s nothing new and nothing special.
I can’t find any information about materials you use.
What’s the enclosure made out of?
Is the deck full carbon or only carbon enforced?
Did you thought about adding bindings on the deck?
What batteries in which configuration do you use?
Videos are nice but nothing tells more than real world experience.
If you think your board perform how you present it, the best way would be to sent out some samples to trusted members here in the for so that they can have a test ride and write a review about it
