Understanding Multi-Impact Capability in Bicycle Helmets

Most traditional bicycle helmets use rigid EPS foam, which is single-impact only: once crushed, it loses its protective performance and must be replaced. By contrast, multi-impact capability means the helmet can withstand multiple collisions without losing its ability to protect the rider.

The Newton-Rider N1neo is engineered with a three-layer, semi-soft flexible protection system featuring a hard polycarbonate outer shell, advanced impact-absorbing polymers, and non-Newtonian inserts. This enables the helmet to compress and rebound, maintaining performance across more than one impact.

Why Multi-Impact Capability Matters

Multi-impact capability in helmets refers to the ability to withstand multiple collisions without losing protective performance. Unlike traditional EPS helmets, which are single-impact only and must be discarded after one crash, the Newton-Rider N1neo is engineered with a three-layer, semi-soft flexible protection system. This system combines a hard polycarbonate outer shell, advanced impact-absorbing polymers, and non-Newtonian inserts that rebound after compression. The result is a helmet that maintains safety across repeated impacts, making it more durable, environmentally responsible, and ideal for daily commuters.

  • Durability: Withstands multiple crashes or bumps without immediate replacement.
  • Safety consistency: Maintains protective ability over time.
  • Urban commuter advantage: Ideal for daily riders who may encounter frequent minor impacts.
  • Environmental benefit: Fewer helmets discarded after a single fall.
