For the most part, every product we sell is water and weatherproof. But this does not mean they're water-tight! If you submerge any of these products in water, it will seep into the openings and likely cause damage. These products are fine in light rain or damp riding conditions. But during heavy downpours or deep puddling, we recommend pulling over and waiting for the weather to subside. If you plan on riding in the rain on a regular basis, we recommend taking some extra steps to further waterproof your e-bike. This includes ensuring all electrical connections are wrapped in electrical tape and all connectors and exposed openings are sealed with clear silicone.
