Fenix BC21R Portable Rechargeable Bike Light

Light Up Your Path

Biking is an excellent form of exercise and an efficient form of travel, but turns into more of a hazard when the sun goes down and both you and your path aren't quite visible. Don't let the sun setting hinder your ability to ride at night with the Fenix BC21R Rechargeable Bike Light, one of the most powerful and convenient bike lights on the market today! Running on either a rechargeable 18650 battery (included) or a pair of CR123A batteries, this light uses its CREE- XM-L2 T6 LED to produce up to 880 Lumens of eye-pleasing neutral white light, able to reach as far as 125 meters ahead! The BC21R features an Optimized Dual Distance Beam System that uses a uniquely-crafted lens to refract a portion of the upper beam downward, taking light that would normally shine in pedestrians' eyes and using it to brighten what's directly in front of you. The BC21R also has three lower brightness outputs of 380, 200, and 100 Lumens, and even features a Flashing Mode that alternates between 380 and 100 Lumens as a means to signal and much more. All five outputs are accessed using the easy-to-use single Body Switch, powering the light on or off with a half second press and switching between outputs by just clicking the switch.

Convenience and Flexibility

The BC21R is designed for easy operation and adjustment, particularly its mounting system. The specialized bike mount clips securely to the base of the light and sides and clips effortlessly onto the shim, which can be easily adjusted to fit on any handlebars using the flexible strap. Once attached, the light can be rotated forward or backward to your preference and can be removed by simply pressing the back of the mount and pulling. Less than 5 inches in length and weighing under 3 ounces, the light can be easily stored in a backpack or pocket when not in use. Charging is also convenient with the BC21R, capable of being charged internally when installed with its 18650 battery using the included Micro-USB cable rather than removing the battery and needing a separate charger. The light can even measure its remaining charge by pressing the body switch while the light is off, causing the red lights on either side to either glow, flash slowly or flash quickly to indicate remaining charge. Even the body switch itself will flash red constantly when the charge is below 20% capacity, alerting the user to either lower the brightness or charge the light.

Safe and Sturdy Design

To perform as a capable bike light, the BC21R needs to be able to perform well when you are out in the elements, when its illumination may be a vital resource. The bike light's body is constructed from durable aluminum alloy and has earned a water resistance rating of IPX-6, capable of enduring powerful jets of water, more than enough to survive the possible rainstorm while out on a ride. The body's design also gives it improved heat dissipation, which prevents the light from overheating during extended use such as a lengthy bike ride. Internally, the BC21R features both overcharge and over-discharge protection to avoid any chances of damaging both the bike light and the battery from charging or overusing, which could affect the runtime and the overall performance of the light. With its powerful output, convenient flexibility, and durable design, the Fenix BC21R is an absolute must-have for any biker!

  • While using an 18650 battery, light is able to be recharged internally using the included Micro-USB cable (WARNING: Do NOT attempt to recharge light internally while CR123As are installed)

Great light let down by mounting system
November 10, 2017
Runtime, output, and beam pattern are all good.

In some ways the rubber stretchy tool-free mount is convenient. But if you make it tight enough that the light won't move around, it's some trouble to get on and off, especially in the cold - and the colder seasons are when you're more likely to need a bike light! The light can be detached from the rubbery mount, but leaving a mount that's so easy to remove on the bike in public doesn't seem ideal, and nor does leaving a rubbery mount on the bike in cold weather.

If there were a more stable (probably tool-required) mount included, or if you could buy such a mount as an accessory, this light would be almost perfect. But the light's mount is subtly incompatible with Fenix's stable bike mount (ALB-10, which works with the BC30R light). So you're stuck with the rubber, and if you're like me you'll be wishing for a more conventional mount pretty quickly.
ProsGood output Plenty of runtime Nice beam pattern
ConsNovelty of the rubber tool-free mount wears off fast Incompatible with Fenix's more stable bike mount options
