NEON

If you are Asian, the official website will recommend a helmet size, but my personal recommendation is to buy the L size because my head circumference is about 57 centimeters. I bought the M size according to the official website's recommendation, but it was extremely uncomfortable to wear and didn't fit well, even the sunglasses couldn't cover my eyes, so I exchanged it and switched to the largest size helmet, and they all fit my head perfectly together. The sunglasses could completely cover my eyes and wouldn't jam my nearsighted glasses. Overall, this is a very practical helmet, and I highly recommend everyone to purchase it, and the exchange service was very fast and satisfactory, no need to say anything! I can't wait to go out and ride my bicycle in my new helmet.

Works quite well the only complaint is the app is very annoying and the email process doesn’t really work

Love this helmet. Fits great. Very comfortable. First time I rode with it, a bicyclist behind me said they loved the lights!
