Short answer: a multi-sport or dedicated e-bike helmet with CPSC certification. You need more protection than a standard bike helmet — but not a full motorcycle helmet. Here's what to know.
Why a Regular Bike Helmet Isn't Enough
Most regular bike helmets are tested at speeds around 12–14 mph. At 20 mph, a crash hits much harder. A standard helmet may not protect you the way you think it does.
The Best Options for 20 mph Riding
- Multi-Sport Helmet — Covers more of your head than a road helmet. Great for commuters and casual riders. Look for CPSC certification — the minimum US safety standard.
- Dedicated E-Bike Helmet — Built for e-bike speeds. Better coverage at the back and sides, tested at higher impacts. The best choice if you ride regularly.
- MTB or Skate-Style Helmet — Good lower back coverage and a tougher shell. A solid pick for urban riding or mixed terrain.
What to Check on the Label
- CPSC certified — required for all bike helmets sold in the US
- ASTM F1952 — a higher standard for more intense impacts
- NTA 8776 — a newer standard made specifically for e-bikes
- No certification label? Skip it.
Know Your State's Helmet Laws
Most US states require helmets for riders under 18. Some require them for all e-bike riders. Check your local laws before you ride.
Bottom Line
At 20 mph, the right helmet is your most important piece of gear. Pick one that fits well, covers the back of your head, and meets US safety standards. Stay safe and enjoy the ride.
