Meet the Ozmo Sidekick — the helmet built for the next generation of city riders.
The Ozmo Sidekick isn’t just another kids’ helmet. It’s purpose-built for the real-world demands of family commuting on e-cargo bikes — engineered to keep up with the speed, energy, and everyday adventures of modern families.
As the first toddler-and-up helmet certified to the NTA 8776 e-bike standard, the Sidekick is designed for riding at e-bike speeds up to 28 mph (45 km/h). That means extended head coverage and advanced protection that traditional kids’ helmets simply weren’t designed to deliver.
Built with Damage Defence technology, the Sidekick is engineered to handle the bumps, drops, and everyday wear that come with active family life — helping preserve its protective performance ride after ride.
And because kids love to make things their own, the Charm Slide system lets them customize their helmet with interchangeable charms. Safety that’s personal, fun, and unmistakably theirs.
Whether they’re riding as passengers on a cargo bike or pedalling on their own, the Ozmo Sidekick helps families move through the city with confidence.
Built for Real-Life Family Riding
-
Flat Back Design
A flatter rear profile makes the Sidekick ideal for use with bike seats and trailers, ensuring a comfortable fit against backrests. -
270° Dial Fit System
An easy-grip adjustment dial allows both parents and kids to quickly fine-tune the fit for comfort, stability, and growing heads. -
Stay-Put Strap Dividers
Adjustable, lockable strap dividers let you dial in the fit once and keep it there as your child grows. Set it and forget it. -
Pinch-Free Magnetic Buckle
The Fidlock magnetic buckle snaps securely into place, making it quick and easy to secure the helmet — even on a wiggly toddler. -
Softer Foam for Softer Skulls
Young children’s heads are different from adults’. The Sidekick uses low-density foam designed to provide safer protection for smaller, softer skulls. -
MIPS Safety System
Integrated MIPS technology helps reduce rotational forces in certain impacts, adding an extra layer of protection. -
Bug-Blocking Vent Mesh
Integrated mesh over the front vents keeps pesky insects out while maintaining airflow on warmer rides. -
U-Lock Vent
A reinforced vent allows you to thread a bike lock directly through the helmet — so you can lock it and leave it alongside the bike.
