Vibration on board

Hi everyone i just purchase my board few days ago so its brand new condition, but upon reaching 17kmh, bang on 17kmh, I feel a vibration throughout the board. The vibration dissipates upon reaching 19/20kmh. Only at speeds in this range [17-19/20]. this only happens in ECO mode and i don't why in PRO and GTR mode it doesn't vibrates
Does anyone have the same issue like mine?

 

Hmm.. Interesting. I haven't tried riding mine in Pro mode to see if it happens to mine. But in Eco mode - yes. Sounds like a software problem.

 

i think it only happens in ECO mode. i tried the bench test, its perfectly fine but when you actually ride on it there is the problem.
vibration and the nose at 17km.....

 

I'm also having the same problem. Got my board today and slight vibration and noise only in eco mode around 15km/hr. Please keep me updated

 

apparently thats normal for a brand new board it will disappear as you ride more

 

I sent my board over to Evolve and got it back just yesterday, they said there's nothing wrong with the board, and they mention its normal for AT boards

 

Ok thank you for quick response!!
