In Stock Ready to Ship
Part Number:




The Bontrager Ion 100 R is a compact but powerful daytime-visible front light. It's designed for the city environment but is equally effective on busy main roads and country lanes.

A wide beam spread, focused optics and an interruptive flash pattern make it visible from over 2km during the day. A built-in ambient light sensor provides auto-brightness control and the included 'Quick Connect' bracket offers simple removal for recharging via the included USB cable.

It's Blendr compatible too, a unique fitting system that makes for neatly integrated Bontrager accessories. Bay Cycles holds a comprehensive range of Blendr mounts in stock, so if you have a Trek bike with Bontrager components we can guide you to the right bracket for your set up.
