Based off experience, no scooter is 100% waterproof. They are, however, water resistant. Most scooters are not recommended for rainy days, as water can get in through the scooter’s cracks and crevices and wreak havoc on the machinations—and that’s not even taking into account potential tire risks! If you need to make a run somewhere with the scooter, weigh the costs and risks before taking it out.
