BC28R

SMART CONTROL BICYCLE LIGHT COMBO

Designed for road cycling, daily commuting, and mountain biking, this Fenix BC28R smart control bicycle light combo brings together a powerful front light and a bright tail light. Riders get up to 2500 lumens from the front unit, with its maximum beam distance reaching 180 meters ahead. It is powered by a long-lasting, replaceable 5000mAh battery and supports USB-Type C charging. Mounting options are versatile, with compatibility for helmet mounts and bicycle light holders with a standard GoPro interface. The front light's anti-glare cut-off beam creates a sharp boundary that lights the way forward without dazzling oncoming traffic. Meanwhile, the compact tail light emits 20 lumens of red light with wide-angle coverage, ensuring visibility from a distance and significantly improving safety during night rides. When paired via smart connection, the front light enables remote control and real-time display of the tail light's current output. Both lights feature precision CNC-machined full-metal construction with an imitation carbon fiber texture and hard anodized finish, offering exceptional aesthetics and reliable durability.

FAQS

Contact Us
1、Can the BC28R front light and rear light be linked for synchronized control?

Answer: Yes.
The BC28R supports intelligent synchronized control between the front light and rear light. After the initial pairing is completed, users can operate the rear light not only with the rear light switch, but also directly switch its output levels using the front light switch for greater convenience.
At the same time, the front light can display the current status of the rear light mode, allowing riders to quickly confirm whether the rear light is in constant-on, slow-flashing, or fast-flashing mode during riding, improving both night riding safety and operational efficiency.

2. How do I pair the BC28R front light and rear light? What should I note when using them for the first time?

Answer: Before first use, the front light and rear light must be paired.
Please follow these steps:

Press and hold the rear light switch for about 5 seconds to enter pairing mode. The rear light indicator will alternately flash red and green.

Single click the lower switch on the front light. The rear light indicator will turn solid green, indicating that the signal from the front light has been received.

Single click the rear light switch again to confirm. Pairing is then complete.

Notes:

After the first successful pairing, the front light will automatically remember the paired rear light, so repeated pairing is usually unnecessary.

During pairing, the straight-line distance between the front light and rear light should not exceed 1.5 meters.

If no operation is performed within 60 seconds, the lights will automatically exit pairing mode.

3. Is the battery in the BC28R front light replaceable? Which batteries are supported?

Answer: Yes, it is replaceable.
The BC28R front light comes standard with one Fenix ARB-L21-5000 V2.0 rechargeable Li-ion battery. This replaceable battery design allows users to quickly swap batteries during long-distance rides or frequent use, helping reduce range anxiety.

Recommended batteries:

Fenix ARB-L21-5000 V2.0

Fenix ARB-L21 Series batteries

Not recommended or prohibited:

Fenix ARB-L18 Series batteries

Standard 21700 rechargeable Li-ion batteries

This is because batteries may differ in size, structure, and protection design. Using an incompatible battery may affect performance and could even create safety risks.

4.Why does the front light battery level indicator only work with certain batteries?

Answer: The battery level indication function of the BC28R front light only works with Fenix ARB-L21 Series batteries.
This is because the battery level recognition function is designed based on compatibility with specified batteries. Only matched Fenix ARB-L21 Series batteries can accurately provide the remaining battery level status.
If a non-specified battery is used, the light may still function, but the battery level indication may be inaccurate or may not display properly. For full functionality and more stable performance, we recommend using officially recommended batteries.

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

Answer: 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.

6. Can the BC28R be used while charging? How long does it take to fully charge?

Answer: Yes.
Both the front light and rear light can be used normally in all output levels while charging, making them suitable for long rides or temporary power replenishment.

Approximate charging times:

Front light: about 3.5 hours from fully depleted to fully charged

Rear light: about 1.5 hours from fully depleted to fully charged

The lights use a USB Type-C charging port. During charging, a solid red indicator means charging is in progress, and a solid green indicator means the battery is fully charged.

7. What should I do if the light flickers abnormally or cannot be turned on?

Answer: If the light flickers abnormally or cannot be turned on, please first check the following two common causes:

Cause 1: Low battery power
Solution: Recharge the battery promptly or replace the front light battery.

Cause 2: Dirty conductive contact surfaces
Solution: Use a cotton swab with alcohol to clean the conductive contact surfaces or contact points on the light or battery.

If the issue still cannot be resolved after the above checks, please contact your dealer or apply for warranty service according to the after-sales policy.

8. What is the operating voltage of the BC28R?

Charging specifications:

Charging voltage: 5V

Front light charging power: supports up to 15W (5V / 3A)

Rear light charging power: supports up to 2.5W (5V / 0.5A)

9.What LEDs does the BC28R use?

Answer: It uses one Cree XHP50D white LED and one red COB light source.

10. If the rear light is turned off by using the lower switch on the BC28R front light during riding, can it be turned on again by pressing and holding the switch?

Answer: Yes. After the rear light is turned off via the lower switch on the front light, it will enter standby mode for one hour, during which the indicator shows a green breathing light. While in standby mode, the rear light can still be controlled normally using the lower switch on the front light. However, if the rear light remains in standby mode for more than one hour without any operation, it will automatically shut down. In that case, the rear light must be turned on manually before it can be controlled again using the lower switch on the front light.

11. My BC28R needs repair. What should I do?

Answer:
1) Free replacement and free warranty repair: Within 15 days from the date of purchase, if the product has a quality issue under normal use, the customer may choose either a replacement or repair service.
