Bell Helmets

Bell Sidetrack II MIPS Youth Helmet

MIPS technology in the best-fitting kids helmet available

The Bell Sidetrack II MIPS sets the standard for youth bike helmets. MIPS technology — used in most premium adult helmets — reduces the rotational forces responsible for concussions in angled impacts, which account for the majority of real-world bike falls. The Fusion In-Mold shell is both light and protective, and the fit dial makes self-adjustment easy for kids.

✓ Pros

  • MIPS liner reduces rotational forces — the most common injury type in bike falls
  • Fusion In-Mold construction: lightweight polycarbonate shell bonded to EPS foam
  • Universal fit dial allows tool-free adjustment across head sizes

✕ Cons

  • Multi-sport certified but not dual-certified for skateboarding (ASTM F1492)
  • Premium price versus non-MIPS options
