Yes, Linky is waterproof to the IP65 grade (see this chart for definition). The electronic components are in an o-ring sealed compartment that does not let in dust or water. This means you can ride in rain and through puddles and the electronics will not be affected. You can also wash Linky. We do not recommend submerging it in a bath, pool, lake or otherwise ;). Also, for safety reasons, although Linky CAN ride in wet conditions, you should be aware that any kind of skateboarding on wet pavement may be dangerous and we don’t advise it.
