Its standout feature is the independent spotlight and floodlight system, allowing riders to customize their beam pattern for long-range visibility, wide-angle trail coverage, or use them together to achieve both.

The BC45R features an OLED display that provides real-time data on battery life, active light sources, and current lumen output. For seamless control mid-ride, the included wireless remote switch provides added access to Instant Turbo and Flash modes. Powered by two high-capacity 18650 batteries, it offers an impressive 6-hour+ runtime on High.

1. *Do not mix batteries of different types or ages. Doing so may cause damage to the bicycle light or the batteries being used.
2. 18650 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Using low-quality batteries or mishandling batteries (such as short-circuiting or overheating) could lead to combustion and jeopardize the safety of users and property. Any adverse effects resulting from the use of low-quality batteries are not covered by any Fenix warranty or liability. Using quality batteries with circuit protection will reduce the potential for combustion or explosion.

Mounting Instructions for the Bicycle Light and the Wireless Remote

2. Hold the light and slide it into the mount until a distinct “click” is heard.
3. Fasten the strap of the wireless remote to the desired position on the bike handlebar.

Note:

1. Adjust the direction of the light before testing the power and functions of the bicycle light.
2. Use the shims provided according to the diameter of the bicycle’s handlebars:
   1. Thick only: diameter 22-28 mm;
   2. Thin only: diameter 28-32 mm;
   3. No shim required: diameter 32-35 mm.

Usage and Maintenance

• Disassembling the sealed head can cause damage to the bicycle light and will void the warranty.
• Replace or recharge the batteries in time to ensure normal use for next time.
• Fenix recommends using excellent quality batteries.
• If the bicycle light will not be used for an extended period, remove the batteries, or the bicycle light could be damaged by electrolyte leakage.
• Recharge a stored bicycle light every three months to maintain the optimum performance of the batteries.
• Long-term use can result in O-ring wear. To maintain a proper water seal, replace the ring with an approved spare.
• Periodic cleaning of the bicycle light and battery contacts improves the bicycle light's performance as dirty contacts may cause the bicycle light to flicker, shine intermittently or even fail to illuminate for the following reasons:
  A: Poor battery level.
  Solution: Recharge or replace the batteries.
  B: The contact or contact point of the batteries or bicycle light is dirty.
  Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.
  If the above methods don't work, please contact the distributor.
