A simple O-ring mount securely attaches to most bicycle seatposts while an innovative magnetic interface allows the light to easily detach from the mount for quick and easy charging accessibility. With its narrow design and compact mount, it’s the perfect taillight for those looking to maintain aerodynamics or attach to seatposts with minimal space, e.g. dropper posts. Designed and produced in-house, the Stick Drive is engineered and built for long-lasting durability and impressive water resistance.
