Setup, Compatibility & Care
Installation is straightforward and requires no tools. Simply stretch the provided silicone strap around your seat post and hook it into the secure locking mechanism. The light is designed to accommodate various post shapes, including circular, oval, and aero profiles.
To charge, pull the light off the mount and insert the integrated USB-A plug directly into a power bank, wall adapter, or laptop port.

Clean the exterior periodically with a soft, damp cloth to remove road grime and ensure the light output remains unobstructed. Do not use harsh chemicals or pressure washers to clean the unit, as this may compromise the waterproof seals.
