The Trek Ion 100 R / Flare R City is a bike light set designed to provide enhanced daytime visibility, combining a compact front light with a rear light specifically designed for urban riding.
Both lights use focused optics, attention-grabbing flash patterns and wide beam distribution to help make the rider more visible on city streets, roads and urban routes.
The combination of focused optics, flash patterns and beam coverage is designed to make the lights visible from up to 900 metres during the day.
The different light patterns help attract attention in traffic and increase the chances of being noticed by other road users.
The Ion 100 R is the front light included in the set, delivering up to 100 lumens. It is designed to increase rider visibility during the day and can also be used in low-light conditions.
Different modes allow you to balance brightness and battery life according to the conditions:
The Flare R City is designed to increase rear visibility in urban traffic. Its wide optics and integrated side illumination help make the rider more visible from multiple angles.
Available modes include:
The Flare R City features integrated side illumination to improve visibility from angles other than directly behind the bike.
This is particularly useful for urban and city riding, where traffic can approach from multiple directions.
LED battery indicators make it easy to check the remaining charge and know when the lights need to be recharged.
Depending on the selected mode, the available settings provide up to 24 hours of battery life.
Both lights are rechargeable and the set includes a USB-C charging cable.
The Quick Connect system also allows the lights to be removed easily from their mounts when they need to be charged or stored.
The set includes two Quick Connect mounts, one for the front light and one for the rear light, allowing quick and easy installation on the bike.
Compatibility with the Blendr system allows the lights to be integrated with compatible mounts for handlebars, stems or helmets.
This provides a clean and discreet installation while keeping the lights easily accessible and functional.
