Factory Price Detachable Visor Bicycle Safety Helmet

Overview

This helmet combines a rigid outer shell with an energy‑absorbing EPS liner and a detachable polycarbonate visor. The design targets urban commuters and recreational riders who require eye protection without sacrificing ventilation or weight efficiency.

Core Design Parameters

• Shell thickness: 2.0 mm ± 0.1 mm (ABS or polycarbonate)
• EPS liner density: 45 kg/m³ ± 5 kg/m³
• Visor thickness: 1.8 mm ± 0.1 mm polycarbonate with anti‑fog coating
• Quick‑release latch torque: 0.45 Nm ± 0.05 Nm for secure attachment
• Ventilation: 12 frontal ports, each 8 mm diameter, plus 4 rear exhaust ports

Materials and Construction

Visor Detachment Mechanism

The visor attaches via two symmetrical latch points located at the temple areas. Each latch incorporates a spring‑loaded plunger that engages a recessed detent on the visor flange. Disengagement requires a downward press of 12 N ± 2 N on the latch release tab, after which the visor pivots upward and separates. The mechanism is rated for 5000 cycles without loss of retention force.

Performance Characteristics

Typical Applications

• Urban commuting where glare and rain protection improve rider safety
• Leisure road cycling on sunny days; visor reduces UV exposure and eye fatigue
• Shared‑fleet bicycles in city‑wide rental programs; detachable visor allows quick cleaning between users
• Cycling events with variable light conditions; riders can stow the visor in a pocket when not needed

Quality Assurance Process

Each production lot undergoes incoming material verification: shell polymer melt flow index, EPS bead expansion ratio, and visor coating thickness are measured against specification limits. During assembly, torque on the latch fasteners is checked with a calibrated driver, and a random sample of 1 % is subjected to a full impact test per EN 1078. Final inspection includes dimensional checks of the visor seating gap (0.5 mm ± 0.2 mm) and functional verification of the release mechanism.

Customization Options

• Shell color: solid Pantone matches or two‑tone combos (minimum order 500 pcs)
• Ventilation port pattern: adjustable number and diameter to suit climate requirements
• Visor tint: clear, light smoke (15 % VLT), medium smoke (30 % VLT), or mirrored finish
• Retention system: optional magnetic buckle or adjustable cam lock
• Branding: pad‑printed logo on the side vents or embroidered strap label

Frequently Asked Questions

• Can the visor be replaced if scratched? Yes, the visor is a separate polycarbonate piece with a standard mounting interface; replacement units are supplied with the same anti‑fog coating.
• What information is required for a quotation? Please provide order quantity, desired shell material (ABS or PC), visor tint, any custom color or branding details, and preferred packaging (bulk carton or individual poly‑bag).
• Are there any certification documents available? The helmet design complies with EN 1078; test reports and CE conformity declarations can be furnished upon request.
• What is the typical lead time for a 2000‑piece order? Production normally completes within 25 working days after receipt of approved artwork and material confirmation, assuming standard material availability.
• How are shipments protected against damage? Helmets are packed in layered corrugated cartons with interleaved foam sheets; each carton undergoes a drop test from 0.8 m on all faces before sealing.
