Rear bicycle light Rockbros Q1 — 7-color LED, Strobe mode, USB-C to USB-A cable, black

Rockbros Q1 is a rear bicycle light designed to provide clear rear visibility with a selectable 7-color LED array and a strobe mode. The compact black housing attaches to the bicycle’s seatpost or rear rack and signals the rider’s presence to other road users in low-light conditions. The light is supplied with a USB‑C to USB‑A cable for recharging and is suitable for urban commuting, evening rides and general safety-focused cycling.

Advantages

The 7-color LED array allows the user to choose a color that increases visibility or matches personal preference while riding. A dedicated strobe mode offers an attention-grabbing flashing pattern that improves noticeability at a distance. Rechargeable via the included USB‑C to USB‑A cable, the light eliminates the need for disposable batteries. The compact black design is unobtrusive and simple to mount, providing consistent rear illumination without adding significant weight to the bike.

How to use

Usage recommendations
