• Runs up to 59 hours, charges via USB Type-C

Built for Fast, Demanding Rides

The BC45R is a high-output bike light for cyclists who want maximum visibility on quick road descents, technical singletrack and dark country lanes. With 3300 lumens at its peak and a throw of 286 metres, it makes riding at night feel much closer to riding by day.

Two Beams in One Light

Inside the housing are two separate light systems. A single Luminus SFT-40 LED produces a tight, far-reaching spot beam, while four Luminus SST12 LEDs create a broad flood for the ground closer to you. Run them individually or together to match the beam to your pace and the terrain.

Nine Modes to Choose From

The modes are split across High Beam, Low Beam and special functions:

• High Beam: High, Medium and Low for seeing far down the road or trail
• Low Beam: High, Medium, Low and Eco for a wider spread closer in
• Turbo: The full 3300 lumens on demand
• Flash: A pulsing mode that helps other road users see you

Live Info on the OLED Screen

The on-board OLED display tells you how much battery remains, which LEDs are running and the lumen output in use, making it easy to plan your runtime.

Wireless Handlebar Remote

The supplied remote sits within reach on the bars, letting you jump straight to Turbo or Flash while keeping both hands on the grips.

Swappable Batteries for Longer Rides

Two Fenix ARB-L18-3400 18650 Li-ion batteries come in the box and deliver as much as 59 hours in Eco mode. Charging is through a sealed, waterproof USB Type-C port. Because the batteries can be replaced, you can bring a charged spare set on big days out.

Rugged Aluminium Body

The aluminium alloy housing is IP66 rated against driving rain and spray and withstands impacts from 1.5 metres, so it's ready to ride all year in any weather.

Backed by a 5-Year Warranty

Fenix covers the light for 5 years, with a 1-year warranty on the batteries and accessories.

Specifications

Output and Runtime by Mode (ANSI/PLATO FL1)

*Turbo runtime includes periods at lower output caused by temperature or protection features.

Results come from Fenix lab tests using two ARB-L18-3400 batteries at 21±3°C and 50–80% humidity. Runtime is the time until output falls to 10% of its starting level, per the ANSI FL1 standard. Actual results can vary with conditions and the batteries used.
