TheFenix BC25R is a lightweight bicycle flashlight with a 600 lumen output and a range of 106 m, designed specifically for operation in urban environments.
Construction
The flashlight's compact body is made of anodized aluminum, which allows for proper heat dissipation and provides protection from rain and dust (IP66 rating). Thanks to its small size, low weight and quick release function from the handle, the Fenix BC25R can also be used as a standard handheld flashlight. The aforementioned bike mount has an instant flashlight release function. To do this, all you have to do is press the locking lever and slide the flashlight out of the bracket.
Optical system
The Fenix BC25R flashlight uses a CREE XP-G3 LED that emits a maximum light output of 600 lumens with a range of 106 m. The light produced is neutral in color, does not tire the eyes, provides accurate color rendition and the ability to recognize more details in night vision conditions. Unlike standard bicycle flashlights, the optical system is designed in such a way as not to blind other traffic users. The specially designed reflector (orange peel) has an innovative cut-off line that blocks the upper part of the light beam. As a result, the flashlight only illuminates the road through the wheel up to the height of the handlebars, without adversely affecting the ability of drivers and pedestrians to see. The maximum range of the light is 106 meters, which in urban conditions provides excellent visibility and the ability to react early to the situation on the road. Power supply The power source is a built-in Li-ion battery with a capacity of 2600 mAh, which, when charged, provides 2 hours of operation in the maximum mode of 600 lumens and 36 hours in the low mode of 50 lumens. The battery is charged via a micro USB port, so we don't have to worry about buying a charger and spare batteries. We can control the battery charge level thanks to the LED indicator, which simply and clearly informs us about the energy status.
Status of the battery level indicator:
- one LED: critical level 0-25%
- two LEDs: low level 26-50%
- three LEDs: medium level 51-85%
- four LEDs: high level 86-100%
Operating modes and operation
Fenix BC25R offers 4 continuous light modes: low→medium→high→turbo and flash light. One large button is used to turn on/off and change brightness, which also activates the battery level indicator. Simple and intuitive operation is a definite advantage for any cyclist, especially in busy urban areas.
Additional features
The flashlight remembers the last used brightness level. When turned on again, the flashlight automatically activates in this mode (memory function). A low battery warning is triggered automatically when the defined voltage level drops (flashing battery level indicator LED). The flashlight also has protection against overheating in turbo mode. In order to reduce the temperature, the controller reduces the brightness by a few lumens, allowing the turbo mode to be activated again.
Mounting
The kit comes with a sturdy bicycle handlebar mount and two spacers to prevent the flashlight from twisting. Mounting is very simple and is limited to tightening one steel screw.

*Light measurements are made under laboratory conditions at a distance of 2 m from the light source.
**Turbo mode operation time is calculated from the moment the overheat protection is activated.
