Helmet AUTHOR Impresa Inmold 55–58 cm silver/white — bicycle safety helmet

AUTHOR Impresa Inmold 55–58 cm in silver/white is a bicycle safety helmet designed for everyday urban and recreational cycling. Built using Inmold technology, the helmet integrates a hard outer shell with an EPS energy-absorbing liner to provide certified impact protection. The model features multiple ventilation openings, an adjustable retention system and a size range of 55–58 cm for a secure, customizable fit.

Advantages

The Inmold construction bonds the outer shell and inner foam into a single structure that improves impact performance while keeping weight low. The adjustable retention system allows quick fine-tuning for a snug fit, and the ventilation openings support airflow to reduce heat buildup during rides. The neutral silver/white finish offers broad visual compatibility with different cycling apparel and accessories.

Suitable for

• Daily commuting in urban environments
• Leisure and recreational cycling on paved paths
• Short to medium duration rides where comfort and ventilation matter
• Riders with head circumference approximately 55–58 cm

When it may not be suitable

This helmet is designed for general urban and recreational use and may not meet the specific requirements of competitive road racing, downhill mountain biking, or electric-motor-assisted high-speed riding where models with advanced aerodynamics, extended coverage or additional certification may be preferred. If you require features such as integrated lights, MIPS or other rotational impact systems, this model does not explicitly include those technologies.

Key specifications

• Construction: Inmold integrated shell with EPS liner
• Size range: adjustable fit for 55–58 cm head circumference
• Ventilation: multiple airflow openings
• Retention: adjustable rear retention system and chin straps
• Color: silver/white
• Intended use: urban and recreational cycling

How to use

Place the helmet level on your head so the front edge sits just above the eyebrows. Adjust the rear retention system until the helmet feels snug but comfortable; tighten the chin strap so that it secures the helmet with room for one or two fingers between the strap and your chin. Periodically inspect the shell and straps for damage and replace the helmet after any significant impact or according to manufacturer guidance. Clean the helmet with mild soap and water and avoid prolonged exposure to high heat or solvents.

What to consider before purchase

• Measure your head circumference to confirm the 55–58 cm size range fits comfortably.
• Decide if you need additional safety features such as rotational impact protection or integrated lighting.
• Check local helmet safety standards and certifications required for your intended use.
• Consider helmet weight and ventilation performance based on ride duration and climate.

Usage recommendations

For optimal protection, adjust the retention system before every ride and replace the helmet after any significant collision. Use the helmet primarily for urban and recreational cycling within the intended speed and terrain conditions.
