This helmet has more than I even knew was possible! We are still figuring out the brake lights and how sensitive it can be but such a genius idea! I didn't want to do less than 5 stars because I really do not have any issues yet. Some have issues with the simplicity of the app but I find it nice as it really is only for a couple setting options and to help alert if there is a fall. No falls yet but did test to see and it did send a push notification as advertised! Will be using this helmet exclusively moving forward.

At 370g, the Livall C21 feels barely there. The built-in LED lights, brake alerts, and fall detection add a great layer of safety. Along with the helmet, it comes with storage bags and a removable visor. My head measures 22 inches, right at the medium/large cutoff. I chose the medium, which fits snugly at its largest setting, but if you’re in a similar spot, I’d recommend sizing up to large.

I am pretty impressed with this helmet. The app is easy to use and the safety features are huge. Love that the back lights up red when braking and even has turn signals. It was also a nice bonus that it came with a storage bag and visor. Really nice touch. If your scooter or ebike goes over 14 mph i definitely wouldn't wear any other helmet since this one seems to be the only one actually certified to protect up to 28mph.

I bought this helmet for my wife. She was looking for a helmet that would fit her better. Others that she found were too loose. The Livall helmet fits well and doesnt have the problem of shaking on her head even when the helmet is strapped tightly like other helmets that are poorly shaped to peoples heads are. She really likes the feature that lets you turn on the lights of the helmet just with a shake, it makes it alot easier. If you like to track your biking progress the app is helpful tracking your distances and speed traveled. The SOS feature is nice to have when biking alone as well. We didn’t want to test it out to make sure it works, but you can set the emergency contact person to be alerted which i think is very helpful. I would recommend this product.

This is for my son for his e-bike. I like that it has the lights on it. It is rechargeable, and fits great.
