Smith Sidekick MIPS JR Bike Helmet
The Smith Sidekick MIPS Jr. Bike Helmet is built for young riders who charge hard and need serious protection to match their energy. With a full-coverage design, MIPS® technology, and lightweight comfort, this helmet keeps kids safe on the trail, at the bike park, or riding around the neighborhood—with grown-up features scaled for smaller heads.
Why we like it:
We love the Sidekick MIPS because it delivers adult-level safety in a kid-friendly package. MIPS® helps protect against angled impacts, while extended coverage in the back and sides offers extra confidence for parents and young riders alike. It’s lightweight, easy to adjust, and cool enough that they’ll actually want to wear it.
Features and Functions:
MIPS® reduces rotational impact forces; 19 fixed vents and internal airflow channels keep kids cool; extended rear coverage boosts protection for trail or street.
Fit and Sizing:
Designed specifically for youth riders, the Sidekick features the easy-to-use VaporFit™ dial system for a precise, comfortable fit. It’s available in youth-specific sizing for a secure, stay-put feel that grows with them.
Bottom Line:
The Sidekick MIPS gives young riders the protection, fit, and ventilation they need to ride confidently—whether they’re just starting out or pushing their limits.
