Feature:

1. SAFE and COMFORTABLE: Our men’s and ladies bike helmet meets both CPSC and CE standards for safety and can withstand whatever weather you can. The battery lasts about 6 hours on flashing mode and 3 on mode. Helmet fits most heads size 54 - 61cm comfortably.
2. SAFETY RIDING: With white LEDs on the front, red LEDs on the back, and orange LEDs for each turn signal - drivers, pedestrians, and other cyclists alike are going to see you coming when you’re wearing a Helmet. Now you can ride in increased safety without the need for a bevy of accessories.
3. FULL STOP: If the Hard Brake Light feature is activated, LEDs on the back of this adult bike helmet will glow red, making it abundantly clear to anyone behind you that you’re slowing down. Note that this feature is deactivated by default to save battery life.
4. TAP TO TURN: When you’re making a turn, simply tap the corresponding button on the included wireless handlebar remote. Even with the helmet - You should still make the appropriate hand signal when you’re making a turn!
5. SMART: The wireless taillight will give you directions to turn left or right, noticeable from quite a distance, and inform the vehicle behind you of your riding intention in time. Adds better visibility to autos and other bicyclists, clear and highly recognizable, to make riding safer.
