Next generation of built-in light seatpost

LightSKIN has expertise in embedding lights into seatposts. This time, it introduces a completely new approach.
LightSKIN has developed a technology that utilizes COB strips to emit light in a continuous line. To achieve this, it designed a uniquely structured seatpost that seamlessly connects the interior and exterior, allowing the COB strip to be securely mounted. At the top of the SF, a specialized lighting module meets StVZO standards. Beneath this module, a built-in COB strip further enhances visibility and safety for riders.

The first built-in brake light seatpost

The SFB is a new rechargeable battery model in the SF series, combining a StVZO-compliant rear module with a red COB strip to preserve the signature built-in light design and design excellence, while remaining compatible with standard bicycles.
It features USB-C direct charging, a low voltage alert, and an automatic sleep mode triggered by a motion-sensitive vibration sensor.
Most notably, it integrates a brake light function that significantly enhances safety by clearly signaling deceleration to following traffic.
