This page brings together our tips on bike helmet accessories: replacement inner foam, visors, lights and rear lights to attach to the shell, camera mounts, waterproof helmet covers, and transport cases. Everything you need to extend the life of a helmet, adapt it for rain or night rides, without ever compromising the head protection.

Extend the life and comfort of your helmet.

Replacement foams: support and hygiene

The foams attached with self-adhesive strips inside the helmet absorb sweat and keep the head snug against the shell. Over time, they compress and retain odors: the helmet then shifts with the slightest bump. A set of new foams, designed for the exact model of the helmet, provides a precise fit. Some manufacturers offer various thicknesses, which are handy for a child whose head is growing or to adjust a helmet between two sizes. These comfort foams do not replace the expanded polystyrene, which is the layer that actually absorbs the energy of an impact.

All accessories can be found on the accessories page.

Visor, lighting, camera: what attaches to the shell

The visor, mainly found on mountain bike helmets, protects the eyes from low sun, rain, and branches; it clips or screws on, and is replaced after a fall. A helmet light illuminates wherever the head turns, a valuable complement to the handlebar light in nighttime turns. A rear light positioned high makes the cyclist visible over cars. Camera mounts stick or strap on: it’s best to use the fixings provided by the helmet manufacturer, as drilling or sticking to the shell can weaken it.

Helmet cover and bag: against rain and impacts

The helmet cover, a waterproof cover that slips over the shell, blocks out rain and cold wind entering through the vents: urban cyclists adopt it as soon as autumn hits. Models with reflective strips add visibility in grey weather. The transport bag, padded, prevents scratches and impacts in a bag or boot, as a helmet that falls heavily needs to be checked afterwards. Solvents, paint, and stickers not approved by the manufacturer are to be avoided: they can damage the shell and polystyrene without anything being visible.

Good deals

Good deals can also be found in the good deals, promotions, clearance, sales, and Black Friday. The new arrivals feature the latest collections, and items shipped within 24h are prepared and dispatched in 24 hours. The highlights of the year follow a steady order: the Black Friday at the end of autumn, the end-of-year holidays, the winter sales, the French Days in spring, then the summer sales and back-to-school season.

Frequently asked questions

Can you wash the foams of your helmet in a washing machine?

It’s better to wash them by hand, in lukewarm soapy water, then press them in a towel without twisting. They dry in the open air before being put back in place, as the heat from a dryer can deform them.

Does a visor fit on any helmet?

No, a visor attaches with clips or screws specific to each helmet model. Therefore, you should choose a replacement visor listed as compatible with your brand and model, otherwise it may not stay on.

Does a helmet cover hinder ventilation?

Yes, by closing off the vents it retains more heat: that’s its role in cold or rainy weather. It should be removed as soon as the rain stops or during heavy exertion, to avoid sweating under the cover.

What accessories should you choose for a child’s helmet?

Differently thick foams allow for adjustment as the head grows. A small flashing light at the back and a colourful cover improve its visibility on the way to school.

How should you store your helmet to make it last?

Store it in its bag, away from the sun and away from heat: a car boot in the middle of summer can degrade the polystyrene. Also, avoid hanging it on the handlebar, where it may fall.
