What sizes does the helmet come in, and how do you measure a child’s head to choose the right size?

The ROCKBROS Kids Full Face Amazon listing gives size S as 19.3–22 inches (49–56 cm) and size M as 22–22.8 inches (56–58 cm). Amazon.com: ROCKBROS Kids Full Face Bike Helmet… The manufacturer advises measuring head circumference with a soft tape about 1–2 cm (0.5–1 inch) above the eyebrows and choosing by measurement rather than age. Kids Bike Helmet | Detachable Full Face…

A separate listing describes a 53–58 cm range and says the helmet is for ages 6–12, which does not match the Amazon size ranges. Rockbros Bike Helmets for Kids and Adults That difference matters: the available sources don’t reconcile the charts, so don’t treat one listing’s figures as a correction to another.

For the ROCKBROS Kids Full Face, measure the child’s head and compare the result with the size chart on the exact listing you plan to use. NHTSA’s measurement guidance also says to place a cloth tape just above the eyebrows and around the thickest point at the back of the head, then compare the result with a helmet chart. Choose the Right Motorcycle Helmet Check fit on the child; age alone doesn’t settle sizing.

How much does the ROCKBROS Kids Full Face helmet weigh?

The ROCKBROS Kids Full Face Amazon listing gives an approximate weight of 380 g (13.4 oz; 0.84 lb). Amazon.com: ROCKBROS Kids Full Face Bike Helmet… The manufacturer gives different mode-specific figures: 440 g in full-face mode and 324 g in half-helmet mode. Kids Bike Helmet | Detachable Full Face…

Those figures don’t align as a single weight: one source gives an approximate listing figure, while the manufacturer separates the modes. The available sources don’t explain the discrepancy or establish that the figures were independently measured. Treat them as reported specifications, not a result from hands-on weighing.

The sources also provide no standard kids’ bike helmet weight for comparison. That means a comparison with a standard helmet can’t be verified from the information available. If weight is important to your decision, the ROCKBROS Kids Full Face figures should be read alongside the mode named by the manufacturer, while keeping in mind that the difference between sources remains unexplained.

What safety certifications and protective features does the helmet have?

The ROCKBROS Kids Full Face listing names a hard PC shell, high-density EPS foam, removable soft inner padding and shock absorption; it also lists 12 ventilation holes.

For the ROCKBROS Kids Full Face, distinguish the manufacturer’s CPSC compliance statement from evidence of ASTM testing: the supplied sources make the former claim but don’t document the latter.

How do you detach and reattach the chin guard, and can it be worn safely in both configurations?

The ROCKBROS Kids Full Face listing describes a button-operated removable chin guard and conversion between full-face and half-helmet configurations. Amazon.com: ROCKBROS Kids Full Face Bike Helmet… The manufacturer calls the switching system one-click. Kids Bike Helmet | Detachable Full Face…

The available sources don’t give detailed steps for reattaching the guard, nor do they provide independent evidence establishing the safety of both configurations. A description of conversion is not the same as a documented assessment of how the helmet performs in each mode. The sources also don’t specify a tested procedure for checking the attachment.

For the ROCKBROS Kids Full Face, follow the instructions supplied with the product and confirm that the guard is secured before use. That is a practical precaution, not a procedure verified by the available sources. If the instructions don’t clearly explain attachment and secure fit, the product information provided here cannot fill that gap. The ROCKBROS Kids Full Face listing establishes that conversion is claimed, not that either configuration has been independently validated.
