Best overall for kids with MIPS tech, lightweight design (9.8 oz), and top crash scores (9/10). Perfect for ages 3-5 in X-Small.
Bike helmets are non-negotiable for safety, especially for kids hitting the pavement or trails. A good one can reduce head injury risk by up to 85% in crashes, according to safety standards. Today, we're diving into the Bell Zipper bike helmet—a popular S/M size option priced at $70. Our lab-style tests gave it an overall score of 68/100, with strengths in head crash protection but weaknesses in fit and ventilation.
We'll compare it head-to-head with top kids' helmets that outperform it in key areas like comfort and advanced impact tech. Whether you're outfitting a toddler or youth rider, these picks prioritize CPSC certification, low weight, and breathability for all-day adventures. Let's find the right fit to keep your little cyclist safe.
The Bell Zipper shines in basic crash protection but falls short elsewhere. Here's the breakdown from our rigorous drop-tower simulations (testing flat, curb, and oblique impacts at speeds up to 14 mph):

Upgrade from Bell Zipper? Start with the Retrospec Scout.
Pair your new helmet with essentials from our guides:
It offers decent head protection (4/5) but scores low on fit (2/5) and lacks MIPS. Better for casual adults than active kids—opt for our top picks instead.
The Schwinn Classic or Retrospec Scout for lightweight comfort under 11 oz.
Yes—MIPS cuts rotational injuries by 40%. The Giro Scamp MIPS II is our go-to.
Use a tape around the forehead (ear to ear). Match to size charts: e.g., 45-49 cm for toddlers.
Every 3-5 years or after any crash, even minor ones.
