The Need for Variety in Rear Bike Lights
Choosing the right rear bike light depends heavily on your riding style and environment. A commuter navigating busy city streets will have different needs than someone enjoying weekend rides in suburban areas or tackling off-road trails.
Urban environments demand high visibility and potentially additional safety features. Suburban or rural riding might prioritize long battery life and simple operation. Off-road adventures necessitate lights that can withstand rugged conditions.
This review focuses on four key lights to highlight the variety of choices and features available. We’ll explore their strengths and weaknesses to help you determine which light best suits your personal cycling needs.
Four Lights Under the Spotlight
The first light is the Exposure Blaze, a reliable and long-lasting option. Despite being over 10 years old, its brightness remains competitive. While its charging cable isn't USB and the flash patterns are somewhat complex, its durability and consistent performance are noteworthy.
Next, the Cat Eye X (and its newer X2 model) offers impressive side visibility with its independent dual-side operation. The USB cover could be improved for water resistance, and it has a tendency to turn on accidentally in bags.
The Click and C Sense Ace represent the newer generation of app-connected lights. The Click uses standard LEDs with lenses for focused power, while the Ace employs COB LEDs for a brighter, more compact design. Both allow customizable flash patterns and offer features such as brighter braking lights and movement alarms.
Testing the App-Connected Lights
Both the Click and C Sense Ace lights offer app connectivity for adjusting flash patterns and brightness. A noteworthy feature is the synchronization of multiple Click lights, useful for group rides.
The movement alarms, designed as theft deterrents, have a limited Bluetooth range. The Click provides notification when it's out of range, whereas the C Sense Ace doesn't.
In practical tests, the Bluetooth range of both lights was approximately 40 meters in a straight line, considerably less when obstructed by buildings or other objects.
Mounting and Durability
All four lights use elastic bands or clips for mounting. The Exposure Blaze’s band is robust and reliable; the Cat Eye X’s feels less sturdy. The Click and Ace utilize versatile clips, allowing for various mounting angles and accommodating bike packs.
Reports of snapping clips exist for the Click and Ace, but in my personal experience, they have held up well even under harsh use. The angle adjustability of the Click and Ace clips offers a major advantage over the other two lights.
Consider the mounting system when choosing a light, as a secure and adaptable mount is crucial for safety and convenience.
Brightness Test and Overall Impressions
A side-by-side brightness comparison test under various light conditions revealed the Exposure Blaze to be unexpectedly the brightest, even at an angle. This highlights that advertised lumens aren't always the sole indicator of real-world visibility.
The Click proved to be the dimmest due to its focusing lenses. While app connectivity and extra features are attractive, brightness and reliability should be prioritized.
The Cat Eye X offers excellent side visibility, while the C Sense Ace boasts brighter output thanks to its COB LEDs.
Conclusion: Which Light Reigns Supreme?
Despite the various features and advertised specifications, the best rear bike light for you depends on your specific needs and priorities. The Exposure Blaze's unexpected brightness and unparalleled durability makes it a top contender, especially for its price point and bomb-proof design.
The Cat Eye X2, with its upgraded COB LEDs and excellent side visibility, offers modern features at a competitive price. However, the Ace’s features make it a stronger contender in the app-connected market.
Ultimately, the C Sense Ace with its COB LEDs and app features is my second choice. While its movement alarm has limitations, the increased visibility and adjustability make it a worthwhile investment. It provides the balance of brightness, features, and ease-of-use which I personally value most. I will still continue testing the Icon 3, once it arrives in April.
