Design flaw not covered by warranty
I have loved using my Niu scooter. However, I live in a rainy country and I do not recommend getting a Niu scooter if there’s any chance it will be exposed to rain / the elements. While the scooter has a latch to cover the battery, it is not enough to safeguard the battery from water damage. Paying €1.500 every time there is a storm is not worth it. Niu refuses to cover weather damage in the warranty - in other words, there’s a denial of the design flaw that compromises the battery in the first place.
