Fenix BTR20 Rechargeable LED Bike Light

A high-quality bike light can pay for itself numerous times over. Buying one well-made piece of gear rather than replacing a poor imitator season after season is the safest bet for both economy and satisfaction. And that’s the mindset Fenix had when they designed the BTR20. Its rugged materials, sleek design, and unbeatable performance combine to make it one of the best LED bike lights on the market.

Versatile Applications

In its brightest, 800 lumen turbo mode, this light can illuminate and trail, field, or park for a wide field of vision even at the darkest time of night. Using an easy pressure switch system, you can tone down the outputs for city or suburban riding. Fenix utilized feedback from cyclists and designed the BTR20’s beam system to refract the upward beam towards the ground. This serves to better illuminate the path you’re most affected by and to reduce the glare experienced by pedestrians in your line of site.

Easy Installation and Recharging

Securely install this light onto your bike’s handlebars and then position the light to your liking. A pressure-switch extends from the rear and can be placed near your thumb for easy activation, deactivation, and mode selection. The BRT20 runs on two customized 18650 batteries (Included) which can be recharged using the included charger cable. Fenix also includes a helmet mount in case you prefer that method.
