Rear Bicycle Light – a smart LED under-saddle light with brake, motion, and light sensors that will increase your visibility and safety on the road and cycle paths

Rear Bicycle Light is a smart bike light, thanks to which you will be visible on the road and cycle paths in all circumstances. The key feature of this under-saddle light is the integrated deceleration sensor. This automatically detects when you are braking, at which point the light shines for 2 seconds with a maximum intensity of up to 60 lumens (lm). This effectively alerts drivers and cyclists behind you that you are slowing down, so they can react.

 

This innovative rear light for your bike is no ordinary blinker. It offers a smart mode with a light sensor, which turns the light on and off according to the surrounding conditions. During the day or in sufficient light, the light turns itself off to save the battery, but the brake function remains active. As soon as you enter a tunnel or it starts to get dark, the light activates automatically. If you park your bike for 2 minutes, the light enters sleep mode thanks to the motion sensor. As soon as you start riding again, it immediately starts to shine again. This means you don't have to manually turn the light on and off. 

 

The rear light for your seat post also has a manual mode. With a single button, you can choose from 6 different modes, including steady and 5 types of flashing (single, double, breathing, flow 1, flow 2). Whether you need maximum visibility during the day or an energy-saving light at night, you will always find the right mode.

 

The body of the light is made from durable polycarbonate, which guarantees a long lifespan. You don't have to worry about riding in adverse weather either, as the light boasts an IPX6 waterproof rating and can easily handle even heavy rain. Power is provided by an integrated battery, which you can conveniently recharge using the included USB-C cable. On a single charge, it provides excellent battery life, which varies according to the selected mode. In steady mode, it can last for approximately 8 hours, while in more energy-saving flashing modes, the battery life climbs to up to 36 hours. When connected to a charger, 4 small diodes inform you of the charging status. When fully charged, all 4 will light up. Thanks to the flexible silicone strap, you can easily and quickly attach the light to the seat post of any bike. What's more, the light is easy to remove from the strap, which is handy when you need to charge it, for example.

 

This rechargeable LED rear light will be appreciated by all cyclists who ride in low-visibility conditions or want to ensure their safety even during the day. It is suitable for daily commutes to work, afternoon rides, and weekend cycling trips in the countryside. Be seen thanks to our rear bike light and ride safely in every situation.

    I expected it to be at least a few centimeters larger, approximately 10–15 cm more, yet such a tiny gadget fell out of the box!! With those two red, antenna-like protrusions, it reminds me of some kind of frog. However, I have it and am using it for now. ✓ Pros: It responds well to braking. ✗ Cons: Surprisingly small!!! And tiny!!!
