CONTACTEZ-NOUS
Qu'est-ce qui rend le casque Lumos Ultra Fly unique par rapport aux autres casques de vŽloÊ?
The Lumos Ultra Fly stands out with its perfect balance of smart lighting and performance. It's exceptionally lightweight, under 250g, making it ideal for long weekend rides. It features improved ventilation, a FlexiFit Retention System for optimal fit, an OptiGrip for sunglass storage, and a Firefly Port for enhanced visibility.
Le Lumos Ultra Fly est-il adaptŽ ˆ diffŽrents types de cyclismeÊ?
Yes, the Lumos Ultra Fly is designed for versatility. Whether you're commuting daily or enjoying weekend cycling adventures, this helmet is a perfect fit. Its lightweight design and enhanced safety features cater to a wide range of cycling activities.
Comment la lampe Firefly amŽliore-t-elle la sŽcuritŽ du casque Lumos Ultra FlyÊ?
The Firefly light, which can be magnetically attached to the Ultra Fly, increases your visibility on the road. It's particularly useful for being seen during night rides or in low-light conditions. This added feature ensures that you're not only protected by the helmet itself but also by being more visible to others.
Combien de temps les lumi�res Firefly peuvent-elles durer sur le casqueÊ?
The battery life of each Firefly light depends on the flashing mode you choose. You can find them here https://ridelumos.com/products/lumos-firefly in the “Product Specifications” dropdown. Additionally, the beauty with replaceable lights is that you can switch out a new Firefly when the existing light runs out of power.
Est-il possible d'installer un Žclairage avant sur ces casquesÊ?

These helmets have a Firefly compatible port only in the rear in order to minimize weight.

How would the turn signals work with this helmet?

You would not be able to show turn signals with just the single Firefly light on the helmet, but you can mount additional Firefly lights on your bike to activate turn signals.
