Helmet keeps the ears warm

I purchased this helmet as it had the ear muffs to cover your ears, I was riding my bike well into the fall last year and I get earaches very easily. Having the covers over my ears made it very east to ride in the morning to play Pickleball.

A revelation

I've been riding with a regular bike helmet for ages and it's always felt like it's perched on top of my head. Plus, I get earache if it's cold, and if I wore a hat and helmet I would overheat. To have ear protectors and a fuller helmet in one package seems a no-brainer, but the market's not crowded with options. So, good fit, even on my huge noggin (I got the biggest size) and no earache, and the price is good too. I'm happy

Excellent delivery price and quality

Came in Useful Sooner Than Expected

The helmet is very comfortable and easy to adjust. Second day out on my new bike and I fell of it twice, no damage to head so the helmet did it’s job

This is the second helmet of this type I have bought. Originally purchased for our eldest son and the second one is for our youngest. Sizing is great and really easy to alter using the rear spin adjustment wheel, a lot better than trying to get the fit with lots of Velcro pads! Quality: really well made! Extras: you can fit a light on the back too! Great for scooter/ bike safety! Ear flaps ( removable/ washable) are a nice touch to keep the chill out, without hindering hearing. No cons! Well worth the money and should last ages ( if looked after). I’d happily have one myself.....

This helmet looks great, is easy to adjust and when used with the light I know my son is safe, helmet is secure and he can be seen! It has cool ear flaps which are a nice addition too but can be removed to wash or to increase ventilation in the summer months. Would highly recommend and I’ll purchase another for my other boy when he’s big enough. 10/10

Stylish Helmet

Bought this as a replacement for my standard white cycle helmet and very pleased with the fit and style. It goes very well with my traditional cycle and because of that I’m much more likely to wear it. Bought another for my brother who has just taken up cycling and doesn’t wear a helmet, hoping he will now! Fit was a bit tight to start but after some adjustments feels very snug. Would highly recommend.

500 City Cycling Bowl Helmet - Chocolate B'TWIN

Comes up quite small so I would recommend you go for the larger size. Velcro’d padded parts in the helmet could be a little more sturdy, they come apart from the helmet far too easily. But all in all it is comfortable when fitted right.

En 1078-certified

Complies with the cycling helmet standard EN1078 (2012) + A1(2013). European standard defining the test requirements and methods applicable to helmets used for skull protection when cycling around town and for skating, scootering and skateboarding. The corresponding test requirements and methods cover the following aspects: construction, including field of vision; shock absorption properties; retention system characteristics.


If you're between sizes, choose the bigger size. Choosing the right-sized helmet and getting the fit right is essential. For children, never buy a helmet that is too big on the assumption that they will grow. M: 21.7" - 23.2" L: 23.2" - 24.4"


For maximum protection, the helmet should be in close contact with your head, and the fastening system must always be correctly adjusted without being too tight around your forehead. When the straps are properly adjusted, the helmet should not slide forward, back or sideways. For this reason, there are several sizes available. We recommend that you try on different sizes to find the best fit.
