SUPER73 x S1 Retro Lifer Certified E-Bike Helmet

Iconic Retro Profile Engineered for Modern E-Bike Speeds

Cruising at 20–28+ MPH on an electric bike requires significantly more protection than a standard, low-speed bicycle helmet can provide. The SUPER73 x S1 Retro Lifer Helmet steps up to the plate. Modeled after timeless vintage skate and motorcycle shapes, this helmet features a deep-fit design that sits lower on the brow and back of the head, ensuring massive structural coverage where you need it most.

Specially Formulated Fusion Foam Protection

At the core of the Retro Lifer is S1’s proprietary, high-impact Fusion Foam liner. Unlike standard soft-foam helmets that compress and fail during rapid impacts, or traditional hard EPS foam that only protects against a single hard strike, S1’s certified configuration is engineered to dissipate both high-energy heavy crashes and lower-velocity multi-impact scenarios—keeping you safe across a spectrum of riding hazards.

Ultra-Plush, Custom Fit with Direct Ventilation

A helmet is only safe if you actually wear it, which is why comfort is a top priority. The Retro Lifer features a sweat-wicking, antimicrobial comfort inner lining that feels incredibly soft against the skin and helps regulate temperature on long summer rides. Paired with strategically placed aerodynamic ventilation ports along the top and rear shell, it maximizes continuous airflow to keep you cool and dry while you focus on the road ahead.
