Intelligent Bicycle Brake Light with Induction Sensor and 420mAh Rechargeable Battery
This intelligent induction taillight is designed for cyclists who want a rear light that reacts to braking. It uses induction sensor technology to work as a brake light, helping to draw attention when you slow down. The unit is powered by a built-in 420mAh battery with a 3.7V voltage, and it charges in approximately 2.2 hours. At about 87g, it adds very little weight to the bike. The IPX6 waterproof rating means it is built to cope with wet weather, and the ABS+PC housing gives the light a rigid, protective shell. It can be fitted in two ways: seat post installation or seat bow installation, and the mounting space needs to be 47-54mm. The taillight is supplied with two kinds of base and is finished in a taillight colour.
Features and Construction
The taillight is built around an ABS+PC housing and an induction sensor. Its rechargeable battery and USB charging setup remove the need for disposable batteries, while the compact body and 87g weight keep it easy to mount on a range of bicycles. The two supplied bases allow fitment to either the seat post or the seat bow.
Material and Build
The housing is made from ABS and PC. ABS gives the light a moulded, rigid structure, while PC is a tough thermoplastic often used in outdoor equipment. Together they form the outer body that holds the 420mAh battery and induction sensor. The IPX6 rating applies to the unit's water resistance, making it suitable for riding in rain. The 3.7V voltage indicates the operating voltage of the rechargeable battery.
Size and Practical Fit
The taillight weighs approximately 87g, so it is light enough to leave on the bike without adding noticeable bulk. The size is as shown in the picture. Installation requires a mounting gap of 47-54mm, which should be checked before fitting. It can be mounted on the seat post or the seat bow using one of the two supplied bases, giving flexibility across different bike setups.
Uses and Placement
This rear light is suited to regular cycling, commuting, and training rides where a brake-responsive light is useful. Its induction sensor and brake light function are the key operational features, and the rechargeable battery supports repeat use without disposable batteries. The two mounting options make it adaptable to different seat posts and saddles.
Event or Professional Use
For club rides, commutes, or longer training sessions, the brake light function can help indicate deceleration to riders behind. The 420mAh battery and 2.2-hour charge time make it practical to recharge between rides. The IPX6 waterproof rating supports use in wet conditions, and the ABS+PC housing protects the internal components from splashes and road spray. Mounting requires 47-54mm of spacing, so check your seat post or saddle rails before installation.
Everyday Home Use
For daily cycling, the taillight can be left mounted and recharged as needed. The induction sensor means it works as a brake light without any manual switching. At 87g, it is light enough for regular use on a commuter or leisure bike. It can be fitted to the seat post or seat bow using the supplied bases. The IPX6 rating and ABS+PC body make it a practical choice for year-round riding in varied weather.
Benefits and Buying Value
The main value of this taillight lies in its rechargeable battery, induction brake light function, and flexible mounting. It avoids disposable batteries and can be moved between bikes using the two supplied bases. The IPX6 waterproof rating and ABS+PC housing support use in wet weather, while the 87g weight keeps the bike light.
Reuse and Low Maintenance
The 420mAh battery is rechargeable, so there is no need to buy disposable cells. Charging takes approximately 2.2 hours. The ABS+PC housing can be wiped clean with a soft damp cloth. The IPX6 rating means the unit can be used in rain, though it should not be submerged. The induction sensor requires no manual operation for the brake light function.
