Smart Brake Sensor and Rear Light for Bicycle
Amelia Y.
San Antonio, TX

Before I got this, cycling after dark was a bit nerve-wracking—I'd rely on my old light that I had to remember to turn on, and it didn't do much beyond just shining. Now, with this gadget, it's like having an extra set of eyes watching my back. It turns on by itself when I start riding, which is a lifesaver since I'm always rushing. The automatic brake warning is clever; it flashes to alert others, though it can be a tad overeager at times. I mostly use it for my evening rides around San Antonio, and it's held up through some light rain without any issues. For the price, it's a solid deal—not perfect, but it does the job well enough. I'd recommend it to other casual riders looking for a bit more safety without breaking the bank. 😊
- Pros: I love how it lights up automatically when I ride, making me feel much safer at night. The warning flash when I slow down is a great touch, and it's super bright, so cars can see me from far away. Recharging it is easy with the USB cable, and it holds up well in rain or shine, which is perfect for my unpredictable Texas weather.
- Cons: Sometimes it feels a bit too sensitive and flashes when I'm just coasting, not really stopping. The installation was mostly simple, but I had to fiddle with it a bit to get it just right—nothing major, but a little annoying for someone like me who's not too techy.
