Is it safe for a baby to wear a helmet while sitting in a bike seat or trailer?

Yes, it’s perfectly safe for babies to wear helmets while sitting in a bike seat or trailer. What’s important is that the helmet fits well, is lightweight, and doesn’t put undue strain on their neck. Helmets designed for these uses often have flatter backs for added comfort when resting their heads against the seat or trailer.

At what age should a baby get a bike helmet?

Babies are typically ready to start wearing helmets from around 9 to 12 months, depending on their physical development and ability to sit up with good neck strength. Two helmets suitable for babies are the B’Twin Baby Cycle Helmet 500 and the Giro Scamp II. As we’ve mentioned, the right size and fit are vital for comfort and safety – so be sure to check, is your child’s bike helmet fitted correctly?

What size helmet does a 1 year-old need?

Even at just one year old, children’s head sizes vary significantly. Typically, a one-year-old needs a helmet sized between 44cm and 49cm. This wide range is why measuring their head is so important. Follow our advice on how to measure your child’s head for a bike helmet, and choose a helmet with adjustable straps or dials for a snug, comfortable fit as your child grows.

How do I choose a bike helmet for my toddler?

There are several factors to consider when choosing a helmet for your toddler. Make sure it meets UK safety standards (explained below). Measure their head for the correct size and look for a helmet with adjustable fit features. Ventilation is also essential to keep their head cool, and the helmet should be lightweight for comfort.

You might also want to pick a helmet with a fun design to make it easier for them to wear regularly.

How much should I spend on a bike helmet for a baby or toddler?

The amount you spend will depend on various factors such as materials, adjustability, design options, and weight. The helmets we’ve listed range from £14.99 to £44.99. All meet the required safety standards, so whatever you choose will be up to the task.

If your budget allows, higher-priced helmets often include additional features like MIPS technology for enhanced protection and comfort features like magnetic buckles.

Is it okay to use a secondhand helmet?

You might be surprised to learn that helmets have a limited lifespan – typically just a few years. Exposure to elements like sun and salt (sweat) can degrade the materials over time. If a helmet has only been used for a short time and stored correctly, it may be okay to pass it down. However, helmets should be replaced after about three years of use or after any impact, even if they appear fine externally.

Helmets are designed for one-time protection, so always be cautious when considering second-hand options.

What is MIPS technology and does my child need it?

MIPS stands for Multi-directional Impact Protection System, designed to reduce rotational forces on the brain during angled impacts. It allows the helmet to move slightly on impact, absorbing some of the force and offering additional protection.

MIPS isn’t essential but does offer added safety, so if it fits within your budget, it’s worth considering. Helmets without MIPS still provide ample protection and meet strict safety standards. For more details, see our article does my child need MIPS in their helmet?

What are all the different bike helmet safety standards?

In the UK, helmets must meet the EN 1078 safety standard as a minimum. Some helmets may undergo additional testing, and we've written a detailed guide on safety standards to look out for when buying a kids’ bike helmet.

Should my baby or toddler wear a full face helmet?

We don’t recommend full-face helmets for babies or toddlers. They are too heavy for their necks to support and aren’t designed for very young children. It’s far better to choose a helmet that’s specifically made for their age, prioritizing comfort and safety. For more on this, check out our article, does my child need a full face helmet when cycling?
