It's time to take your helmet even further. The Livall EVO21 smart bike helmet offers true 360° coverage, with a brake warning light and turn signals for visibility from all directions. With 30% more ventilation and a 350g lightweight design, you’ll stay ahead of the pack while cutting down on sweat.


SOS – Patented fall detection

The Livall EVO21 features patented fall detection and SOS technology. So in the event of a fall it sends a text message alert to your emergency contact with your exact GPS location. When you’re riding at night, the dangers are everywhere. The Livall EVO21 lets you keep your eyes on the road, instead of worrying what’s behind you. 

Wide-angle front lights and super-bright 270° rear lights are integrated into the helmet, maximizing your visibility even at long ranges, while smart LEDs signal to drivers what you’ll do next - stop, turn, or ride on through. Plus, three dynamic light effects will make sure you get noticed on any street, improving your safety and helping you ride in style.

Automatic Brake Warning Light

Get in sync with your cycle. The Livall EVO21 has sensors to detect when you’re slowing down or coming to a stop, and it automatically turns on the brake lights on the back of your helmet. Letting other riders and motorists know you’re stopping. And keeping you safe and secure, night and day.


Wide Beam-angle Front Light

Cyclists tend to lower their heads to gain extra speed while riding. The problem is, this can reduce your visibility to drivers - even if your helmet has a light.

To tackle this challenge, we developed a front light with a 45° reach, so it can be seen even if you’re tucking your head for a sprint. The Livall EVO21’s wide beam light will shine through at any angle, making you visible at long distances and letting everyone know you’re coming.


IPX5 Waterproof

Rain or shine, this helmet is IPX5 waterproof, so the LED lighting system and remote will run smoothly in any weather, having passed rigorous low-pressure spraying testing. The total water volume in this testing is much greater than that of rainstorm days. So the Livall EVO21 can not only deal with moderate rain with ease, but also survive heavy rain. 


10 Hour Battery Life

When you’re riding down a pitch-black country lane the last thing you want to think about is your headlights dying. 10 hours of battery life on a single charge should hopefully be enough to ease your mind. That’s about a week's worth of commuting for the average cyclist.


Livall App

Get the most out of your ride with the Livall Riding App. Customize everything from light settings, turn signals, battery reports and daily cycling records. And the App links up to Livall's community of like-minded riders. So next time you see a beautiful sunrise on your morning commute, you can easily share it with your friends.
