Our small helmet fits head circumferences between 48-53cm. Our medium helmets fit head circumferences between 54-58cm. The measurement (in cm) refers to the circumference around the largest part of the rider's head (approximately 1cm above the rider's eyebrows).

Yes! We have a ring adjuster at the back of the helmet (with an integrated LED light) which tightens and loosens to ensure the helmet fits snuggly to you're the rider's head. The straps that clip under the chin are also adjustable. The ring adjuster should be tightened until the fit is firm, but comfortable and the chin strap should fit snugly under the chin.

No. If the helmet has suffered an impact (even if there is no visible damage), or when it shows obvious signs of wear and tear, you should discard and replace it. It is recommended that helmets are replaced after 4-5 years after initial use or within 8 years of production.

If your LED light at the back of the helmet has stopped working, then it almost certainly needs new batteries. Unscrew the two small screws and put in 2 new AG3 batteries or 1 new CR2032 battery depending on which LED you have. If this doesn't fix the problem, then contact us and we will help!
