Bell Sidetrack II Mips vs Joovy Noodle Kids Bike Helmet
Which should you buy? Our verdict on both, pulled from our full The Best Kids' Bike Helmets: 4 Compared (and One to Skip) comparison.
The Sidetrack II Mips pairs a Mips Evolve layer with a genuinely easy dial and two universal shell sizes that cover a wide span of school-age heads. The Joovy Noodle is a budget-tier pick, carries the age 1 and older extended head coverage certification the Bell does not, and is the smarter buy for a rider still on a balance bike.
Bell Sidetrack II Mips
Buy itThe default school-age helmet: Mips Evolve, an easy one-handed dial, and two universal shell sizes for school-age kids.
- Bell lists Mips Evolve, which integrates the low-friction layer into the retention system instead of adding a separate liner.
- The Ergo Fit dial has a rubber overmolded knob that an adult can turn one-handed while the kid is already on the bike.
- Two universal sizes, 47 to 54 cm and 50 to 57 cm, mean one helmet can last several growth spurts.
- Bell's certification wording is for persons age 5 and older, so it is not the extended head coverage version a toddler should be in.
- Bell does not publish a vent count for this model, which makes hot-weather comfort hard to judge before you buy.
- At a listed 360 g in the youth size it is heavier than the lightest kids' helmets here.
Joovy Noodle Kids Bike Helmet
Buy itA budget-tier helmet that still does the two things that matter most: extended head coverage certification and a real adjustment dial.
- Joovy states it complies with the US CPSC standard for bicycle helmets for persons age 1 and older with extended head coverage, the category built for small children.
- The dial-adjust fit system sits low at the back of the helmet, so it is easy to reach and tighten on a wriggling toddler.
- Joovy lists 14 vents with integrated bug mesh and a weight of 7.2 oz, which is a lot of airflow for the money.
- Joovy does not list Mips or any other rotational-impact system for the Noodle.
- Joovy publishes the size ranges in inches only, 18.5 to 20.5 in and 20.5 to 22 in, so you have to convert to compare with cm-based brands.
- Joovy describes the visor as extended, with no removal option mentioned.
