Trek continues its legacy of innovation in cycling safety with the Flare R City Rear Bike Light, a compact yet powerful solution for urban riders. Designed to maximize visibility in high-traffic environments, the Flare R City is visible during the day from up to 900 meters away, thanks to its focused optics and an attention-demanding flash pattern that stands out—even under direct sunlight.

Built for real-world conditions, the new generation of the Flare R City offers up to 40% more run time than its predecessor, with an impressive 24-hour maximum battery life. The integrated LED fuel gauge keeps riders informed about battery status, while the IPX7 waterproof rating ensures optimal performance in any weather condition. Side lighting enhances safety by expanding the beam profile, making cyclists more visible at intersections and in low-light conditions.

Charging is simple and efficient via the included USB-C cable, and Trek’s Blendr compatibility allows for seamless mounting on handlebars, helmets, or seat posts. For commuters, night riders, and weekend explorers alike, the Flare R City proves that minor upgrades can make a huge difference in safety and confidence on the road. 

Backed by Trek’s research—showing cyclists with daytime running lights are up to 240% more noticeable to drivers—this light isn’t just an accessory; it’s an essential tool for urban riding. At $45, it delivers reliability, visibility, and peace of mind—all in one lightweight package.
