Where innovation and functionality meet, SEEMEE 50 PRO evolves the Optillumin lens with an output of up to 50 lm, optimized to increase visibility without compromising safety during night riding. The new magnetic mounting system makes installation instant: snap-on, no tools required. With silicone shims for round and aero seatposts, the taillight stays stable on different frame geometries.

Designed for group rides, it features the PelotonSync Flash and FTR LightSync Control functions. The first synchronizes multiple taillights in a simultaneous flash to make the group more visible to approaching vehicles; the second allows you to manage front and rear lights with a single click from the remote, reducing distractions. Every detail is oriented toward end use: unibody polycarbonate (PC) housing for greater robustness and clean finishes, side button with immediate feedback, four-level battery indicator, USB-C fast charging, button lock, and IPX6 waterproofing to work in any condition.
