Urban commuters who skateboard or ride bicycles face similar head‑impact risks from falls, collisions with curbs, or interactions with traffic. Effective protection depends on a helmet’s ability to manage kinetic energy, distribute load, and stay securely positioned during sudden movements.
The helmets are tested to meet ASTM F1447 (skateboard) and EN 1078 (bicycle) criteria, which specify a peak acceleration limit of 300 g and a duration‑dependent energy absorption threshold. These benchmarks ensure that, under standardized drop‑test conditions, the helmet reduces transmitted force to levels associated with low risk of skull fracture.
A typical medium‑size shell weighs between 320 g and 380 g, depending on the chosen material lay‑up. Ventilation is provided by 12 to 18 engineered apertures, each shaped to promote laminar airflow while maintaining structural integrity around the perimeter.
The process begins with receipt of a vector logo file (AI, EPS, or SVG) and confirmation of placement area (front, rear, or side). A digital mock‑up is generated to verify contrast and clearance relative to ventilation channels and retention system.
In dense city environments, skateboarders frequently encounter abrupt stops caused by uneven pavement or unexpected obstacles, generating rotational forces that a well‑fitted helmet mitigates through its internal retention system. Bicycle commuters benefit from the same protection when navigating shared lanes, where low‑speed side impacts are prevalent.
Each production lot undergoes random sampling for impact testing per the relevant standard, with a minimum of three specimens per size. Additionally, retention‑strap strength is measured using a tensile tester, requiring a minimum breaking force of 225 N to prevent accidental release during a crash.

| Parameter | Typical Value | Notes / Customizable |
|---|---|---|
| Shell Material | ABS / PC blend | Alternative: fiberglass reinforced polymer |
| Core Material | EPS (20‑25 kg/m³) or EPP (30‑35 kg/m³) | Selected per impact‑multiplicity requirement |
| Weight (Medium) | 320‑380 g | Varies with core and shell thickness |
| Ventilation Apertures | 12‑18 | Pattern adjustable for airflow vs. coverage |
| Impact Standard | ASTM F1447 / EN 1078 | Certification available upon request |
| Logo Application Method | Screen printing or heat‑transfer vinyl | Based on logo complexity and color count |
| Retention Strap Breaking Force | ≥225 N | Tested per EN 1078 clause 5.2 |
Yes, the retention system incorporates a dial‑adjustable cradle allowing a fit range of 52 cm to 58 cm head circumference.
Vector formats (AI, EPS, SVG) are preferred; high‑resolution raster files (≥300 dpi) may be accepted with potential additional setup fees.
Typically, the minimum run is 50 units; lower quantities can be accommodated as a sample program with adjusted pricing.
A pre‑production sample undergoes the same impact and adhesion tests as production units; approval is based on meeting all specification thresholds.
