Limited Time Special Offer: Free LED rear bike light with cool laser function! Powered by 2 x AAA batteries with simple user interface to select ideal mode.

The Fenix BT20 bike light is extremely compact yet offers amazing performance at a very reasonable price.

It can be used as a regular bike light attached to the handlebars or as a helmet light with the supplied mounts, making it perfect for the daily commute or blasting some tails on your mountain bike.

The BT20 is powered by either 4 x CR123 or 2 x 18650 Li-ion batteries (not included), which are housed in a separate battery magazine.

The Fenix BT20 has a Cree XM-L T6 Neutral White LED giving excellent colour rendition & penetration in bad weather.

The BT20 aspherical reflector produces a dual beam system that provides a broad flood beam at close range and a long throw narrow beam of up to 156 meters.

The bike light includes o-ring style handlebar mountings that enable quick positioning & removal and there is also a helmet mount.

Other features include an intelligent power indicator allowing the user to see how much battery power is remaining whist riding.

The beam can be adjusted left - right by rotating on its spindle & the torch can be fitted to handlebars of 20 - 35 mm diameter using the simple quick release o-ring mounting system.
