Frequently Asked Questions
Just like our bikes, all our helmets are unisex. The most important thing is to measure your head before ordering.
The best way to ensure the helmet will fit you is to measure your head. This is also the case for kids, as age is not a good indicator.
How to Measure Your Head:
1. Have a flexible tape measure and place it around the circumference of your head.
2. Position the tape measure at the middle of your forehead, 2 fingers above your ears and the widest point at the back of your head.
3. Note the result, and then browse our amazing helmet range! Be aware that sizing varies from model to model.
We have 3 models of helmets, and they have different sizing, but as long as you know your head measurement, you will find the perfect one for you.
Don’t worry, our helmets are safety certified so that you and your little one can ride with ease! Your new Bobbin helmet is both EN1078, and CPSC tested, featuring an ABS shell with EPS foam for extra protection, a dial fit sizing system and 11 ventilation spots to allow your head to breathe.
Yes, you can wear a Bobbin bike helmet for skateboarding and roller skating. All our helmets are CPSC-compliant.
Our Starling helmet is our classic bicycle helmet for both children and adults. It has a simple, clean shape and comes in a large selection of colours and 2 sizes.
