BELL children's helmet SIDETRACK II MIPS — universal size 47–54 cm, Strike Gloss Blue Green

BELL SIDETRACK II MIPS — universal children's helmet designed to protect young riders with a comfortable fit for head circumferences from 47 to 54 cm. This model integrates MIPS rotational impact protection into a lightweight in-mold shell and offers adjustable fit and ventilation features for everyday cycling, urban commuting, park trails and leisure rides. The Strike Gloss Blue Green finish provides visible color contrast while remaining suitable for a variety of bicycles and casual apparel.

Advantages

The helmet combines MIPS technology for diminished rotational forces with an easy-to-adjust retention system that secures a stable fit across the advertised size range. Its in-mold construction keeps weight low while providing impact absorption, and multiple vents maintain airflow to reduce overheating during activity. The design balances protection, comfort and usability for children who cycle regularly.

How to use

Place the helmet on the child’s head so it sits level and low on the forehead, covering the upper part of the forehead without tilting back. Adjust the rear retention system until the helmet fits snugly without pressure points, and fine-tune the side straps so the buckles sit just below the ears. Secure the chin strap and adjust the length so only two fingers can fit between the strap and the chin. Check fit and straps before each ride and follow the helmet’s labeling for any specific care or replacement guidance.

Usage recommendations

Use the helmet for all cycling activities appropriate to the child’s skill level; replace the helmet after any significant impact or if signs of damage appear. Clean with mild soap and water, avoid solvents or harsh chemicals, and store the helmet away from direct sunlight and extreme temperatures to preserve shell and liner integrity.
