Smart Bike Rear Light with Brake Sensing & Sync Mode

Ride with confidence day or night. This smart rear light reacts instantly when you brake, giving drivers and riders behind you a clear signal to slow down.

It works in the background so you don’t have to think about it—lighting your way, saving power, and keeping you visible when it matters most.

✅ Brake sensing lights up for 3 seconds to alert traffic behind you

This rear light mounts securely to your seatpost or saddle area and stays stable while you ride. Its intelligent sensing detects braking automatically, increasing visibility without any extra action. When you stop, it enters sleep mode after 30 seconds, then wakes instantly when movement is detected.

When riding with others, sync mode keeps multiple lights flashing together within a 50m range. This creates a more noticeable presence on the road, especially in low-light or busy conditions. The built-in memory function restores your last used mode so you can ride without resetting preferences.

The compact 39×39mm size and lightweight build (about 106g) make it easy to install without adding bulk. USB charging keeps things simple, and the LED indicator shows battery status clearly so you're never caught off guard.

Compared to basic rear lights, this one actively responds to your movement, improves group visibility, and reduces the need for constant manual control.

Stay seen, react faster, and ride with confidence every time.
