Product highlights

The Fenix BC25R is a 600 lumen bike light visible from up to 347 feet, built to keep your ride simple and dependable. An easy-to-use quick-release mount, single-switch control, and a built-in battery level indicator make charging and operating this light genuinely effortless, whether you're commuting at dawn or riding home after dark. An anti-glare cut-off facula keeps your beam road-focused, protecting pedestrians' visibility instead of blinding them.

A 2600mAh Li-ion battery keeps the BC25R running ride after ride, and an IP66 rating means rainy commutes aren't a problem. All-metal heat-dissipating fins keep the light running cool even during extended use, adding real longevity to a light built for daily riding. For cyclists who want a straightforward, dependable bike light without unnecessary complexity, the BC25R gets the job done every time you clip it on.

Operating Instructions

On/Off: Press and hold the switch for 0.5 seconds to turn the light on/off.

Output Selection: With the light switched on, single click the switch to cycle through Low → Med → High → Turbo.

Flash: With the light switched on, double click the switch to enter flash, single click to turn back to general mode.

Battery Level Indication

With the light switched off, single click the switch to check the battery status. The battery level indicators will display the battery status for 3 seconds.

  • One light on: critical, 0% - 25%
  • Two lights on: poor, 26% - 50%
  • Three lights on: sufficient, 51% - 85%
  • Four lights on: saturated, 86% - 100%

Charging

One standard Micro USB charging cable, which can be used for charging other digital devices, is included.

Operation: With the light switched off, remove the dust cover of the bicycle light to reveal the charging port, and plug the Micro USB end of the USB cable into the light's charging port, then connect the other end of the USB cable to a USB power adaptor.

Charging Indicator: The indicators near the switch will display charging status. Four indicators will remain constant on when the battery is fully charged.

Note: 1) Once charging is completed, be sure to remove the charging cable and replace the dust cover. 2) The normal charging time of the built-in battery is 2.5 hours from fully depleted to fully charged with the light off. 3) Recharge the light timely when the battery level is critical, for future use. 4) Recharge a stored light every three months to maintain optimal battery performance. 5) Only Low output can be used while the light is being charged, but charging time will be prolonged.

Intelligent Memory Circuit

The light memorizes the last selected brightness level on General mode. When turned on again, the previously used brightness level will be recalled.

Overheat Protection

The light will accumulate a lot of heat when working on Turbo mode. The light will automatically step down a few lumens to reduce the temperature, to reselect the mode.

Low-Voltage Warning

One of the indicators flashes when the battery level is critical. When the voltage level drops below a preset level, the bicycle light is programmed to step down to a lower brightness level until Low output is reached. To ensure normal use, the bicycle light will work until the battery runs out.

Mounting Instructions

Bicycle Light and bike mount:

  • Unscrew the screw of the bike mount. Fix the bike mount in the desired position on the bike handlebar and fasten the screw.
  • Loosen the fine adjustment screw of the handlebar mount before clamping the mount to the bar by securely tightening the set screw.
  • Slide the light into the mount until a distinct "click" is heard.

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 — thick + thin shims together for a 22-28mm diameter bar, thin only for a 28-32mm diameter bar.

Usage and Maintenance

  • Disassembling the sealed head can cause damage to the light and will void the warranty.
  • The light will accumulate a lot of heat when working on Turbo mode. Do not touch the heat dissipation fins.
  • For secure transportation, the bicycle light is not fully charged before delivery. Recharge it before first use.

Reviews

This light for the win

"I’ve had three $50 bike lights. This one is easily the best. Seems like it was designed by people who ride bikes. The clamp fits on 31. 8mm which is usually a challenge for the rubber band type lights that eventually snap due to the stretch. It’s bright, charge is adequate, and removing light to recharge is easy with the slide clip."

"It is good"

Great light for my morning

"Great light for my morning rides"

— Travis D. (5/5)

Now you see me

"I haven’t had the opportunity to use it in darkness yet, but it is doing a supreme job in the daylight. One of the issues I have (far too often) when riding is people not noticing me on approach. So many times someone either pulls in front of me, cuts a corner on top of me and other non friendly maneuvers. This may seem like a lot, but I am on the bike a lot, normally 5 days a week, 12+ hours. I have not experienced any of the actions on this list since mounting and using this light, so I am in love. I’m confident that low light use will be as exceptional."

— Billy C. (5/5)

Sweet bike light

"Mounts super easy. And way bright!!!"

Gread Value Bike Light

"The light is solid. The mount simple and reliable. Power and run time are terrific. This light meets my riding needs perfectly."

— Greg (5/5)

"Love it. Very solid. Very bright."

— Jeff (5/5)

Worth It!

"I love this light. It's powerful and allows me to see everything in front of me. I also love the mount. It looks like it accommodates for constant bouncing when bike riding. I like the multiple settings from hight, low, flashing, and so on."

— Steve S. (5/5)

Fantastic bike light!!

"This light is everything a bike light should be: small size, powerful enough, easy to use and charge, lightweight, and uses a solid mounting system. And the mount has a quick-release for split-second removal of the light, when parked or just to use as a regular flashlight. For people new to biking now, you have NO idea how good you have it with products like this!!!! I kid you not. I was biking long before LEDs were a thing. Matter of fact, I remember using a bike light as a kid, where the light had a "roller" that rubbed against the side of the tire as it rotated in order to give the light its meager power output!! I'm not joking. Had to be rough on tires, not to mention cause a lot of unwanted friction on the wheel. Today, WOW!!!! The technology and choices are staggering! I'm getting back into biking at 58 yrs old, after 15+ years away. It's easy to see that Fenix bike lights are head and shoulders above others, due to the quality, design, and long battery life. I just received this BC25R today and tried it outside in bright sunshine. I was amazed how bright the light was even on the high setting (350 lumens), and also VERY noticeable on the flashing setting (150 lumens). A great addition for daytime riding for added visibility!! And I also didn't see the BC26R before I ordered the 25R. So because I'm a bit of a tech geek and maybe even a little crazy, I also ordered the 26R and will use BOTH on my bike to be a beacon of visibility on the road! ;);) One on each side of the handlebars. This will be fun!!!"

— Joe (5/5)

I like the beam so

"I like the beam so that pedestrians or any oncoming traffic are not interfered with. And light is plenty bright. I'll have to see with further use how the battery lasts, which I don't foresee any problems."
