There’s no real way to tell
that. It all depends on how you treat it and how much if, at all, you take care
of it. Remember that electric skateboards are not waterproof; they can be
water-resistant at max. So, if you happen to leave or ride your e-board out in
the rain or drop it constantly from X feet, then rest assured that your
electric skateboard will abandon you in no time.
So you see, it’s all up to you. Take good care of it and read the instructions manual carefully to know the dos and don’ts.
