Fenix BC28R Rechargeable Bike Light Set

The Fenix BC28R Rechargeable Bike Light Set is the ultimate all-inclusive lighting solution for cyclists who prioritize safety and convenience. This premium set includes both a high-output bike light and a red taillight, uniquely engineered to work in tandem. With wireless-linked control, you can change the taillight modes directly from a dedicated button on the front bike light, allowing for seamless adjustments to both lights without dismounting.

The forward-facing bike light delivers a powerful 2500 lumens that can illuminate distances up to 591ft (180m). Designed with commuters in mind, the beam features an anti-glare cut-off facula line that prevents blinding oncoming traffic and pedestrians. Both lights are USB-C rechargeable, with the primary light powered by a high-capacity 21700 battery. Featuring an IP66 rating for heavy rain resistance, the BC28R set offers professional-grade visibility and total control for every ride.

Warning:

*21700 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.

Usage and Maintenance

• Disassembling the sealed heads can cause damage to the product and will void the warranty.
• Fenix recommends using an excellent quality battery.
• If the front light will not be used for an extended period, remove the battery, or the front light could be damaged by electrolyte leakage.
• Recharge a stored product every three months to maintain the optimum performance of the batteries.
• Periodic cleaning of the product and battery contacts improves the product's performance as dirty contacts may cause the product to flicker, shine intermittently or even fail to illuminate for the following reasons:
  A: Poor battery level.
  Solution: Recharge or replace the battery.
  B: The contact or contact point of the battery or the product 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.

Why does the BC28R front light use a cutoff beam design? What are the benefits?

A: The BC28R front light uses a cutoff beam design primarily to illuminate the road ahead while reducing glare for oncoming pedestrians, cyclists, or drivers.

Compared with ordinary flood lighting without a defined cutoff, the cutoff beam directs the light more precisely onto the effective road surface area. This helps riders see the road clearly while also meeting the needs of safe and courteous riding, especially in urban roads and daily commuting environments.
