Giro Tremor Child Bicycle Helmets

The Giro Tremor Helmet is a top choice for young riders, combining awesome style with high-performance features inherited from our adult line. It offers an easy-to-adjust fit system and superior breathability, making it a major hit with little shredders on the trail.

Premium Technology and Fit System 

Featuring best-in-class technologies, the Tremor ensures your child is ready for any ride with reduced weight and enhanced security.

• In-Mold Construction: This advanced technology is borrowed from our adult helmets for reduced weight and enhanced durability.

• Hardshell with In-Mold Hardbody™ Lower Wrap: The two-piece shell combines a tough outer hardshell with a polycarbonate lower shell that is permanently fused to the EPS liner. This provides exceptional durability without adding excess bulk.

• Roc Loc® Sport Fit System: Our acclaimed system for fast and secure fit adjustments. It offers easy one-handed operation and a broad 7cm adjustment range.

  • Confident Adjustment: The confident clicking feel and sound let riders know the helmet is securely adjusted to a comfortable fit.

  • Premium Functionality: Brings premium function to sport-level helmets, offering comfort similar to Roc Loc 5 and is ponytail compatible. 

• 18 Vents for Breathability: Strategically placed vents ensure superior airflow, keeping young riders cool and comfortable on long rides.

Universal Fit™ Sizing Advantage 

The Tremor uses our proprietary sizing system to ensure a perfect fit right out of the box, eliminating the hassle of complex sizing charts.

• Universal Fit™ Sizing: Helmets are sculpted to look great and fit comfortably for almost anyone on the first try.

• Easy Adjustment: Proprietary shell sizes are combined with the easily-adjustable Roc Loc Sport system, making it simple to get the right fit, straight out of the box.
