SIFVO Adult Bike Helmet, Black, Size Medium, Removable Visor and 18 Vents, for Men and Women

The SIFVO Bike Helmet is a lightweight, full‑coverage mountain and road cycling helmet with an adjustable fit and removable visor designed to protect adult and youth riders from impacts while improving comfort and airflow.

This helmet pairs a tough matt polycarbonate shell with a reinforced EPS impact liner and meets CPSC, CE and ASTM safety standards. Built for mixed-terrain riders, it balances protection, ventilation and fit adjustability so you can ride longer without distraction. The removable visor shields your eyes and face when needed and the helmet accommodates head sizes from 54 to 62 cm in the M/L range.

How does the SIFVO helmet protect my head during cycling?

Protection comes from integrated molding that bonds the hard outer shell to a dense inner EPS core, dispersing energy from impacts. The extended rear coverage adds protection to the occipital area, which is often exposed in lower-profile helmets.

• Integrated PC shell fused to thickened EPS core for better impact absorption
• Full-coverage design reaches the back of the head for extra protection
• Certified to CPSC, CE and ASTM safety standards

Will this helmet keep me cool on long rides?

Yes — its ventilation layout uses 18 vents to channel air through the helmet and reduce heat buildup. The airflow design also helps lower aerodynamic drag compared with closed helmets, which makes it more comfortable on extended outings.

• 18 strategically placed vents for continuous air circulation
• Internal channels guide air from front to rear for efficient cooling
• Vent layout minimizes wind resistance while riding fast

How do I get a secure, comfortable fit?

The helmet includes an easy-turn rear dial and soft chin strap so you can fine-tune the fit quickly, even while wearing gloves. Its lightweight construction reduces neck strain on multi-hour rides, and the padding can be adjusted or removed for cleaning.

• Rear adjustment knob for precise circumference control
• Soft, adjustable chin strap with quick-release buckle for convenience
• Lightweight design reduces fatigue during long rides

What practical features does the visor add?

The detachable visor blocks sun glare and helps guard your face from low branches or debris without obstructing your view. It can be removed for a sleeker road-bike profile or reattached for trail and commuting use.

• Removable visor for sun protection and trail hazard shielding
• Does not impede vision or airflow when mounted
• Simple clip system allows quick on/off changes

Who is this helmet for? The SIFVO Bike Helmet is aimed at cyclists who want a versatile helmet that works for mountain trails, gravel roads and urban commutes. It's suitable for adult and teen riders needing a medium/large size (54–62 cm), riders who value airflow and lighter weight, and cyclists who want a certified helmet with practical features such as an adjustable fit system and a removable visor. Choose this model if you want dependable protection, everyday comfort and the flexibility to switch between trail and street use without buying multiple helmets.
