What's the major difference between the Ultra Fly Pro and the Ultra Fly?
The Ultra Fly Pro builds upon the solid foundation of the Ultra Fly, introducing enhancements tailored for the avid road cyclist.

It features increased ventilation with more vents, a sophisticated 3-piece polycarbonate shell for enhanced protection, and a magnetic Fidlock buckle for easy, secure fastening.

Designed for seasoned cyclists, the Ultra Fly Pro offers superior cooling, a more advanced fit system, and integration with our Firefly Smart Lights for unmatched visibility.
How does the magnetic Fidlock buckle work? Is it safe?
The Fidlock buckle uses a unique magnetic mechanism that allows for easy, one-handed operation, even with gloves on.It's designed for both convenience and safety, securely locking in place with a satisfying 'click.' The buckle has been rigorously tested and is rated for pull strength of over 143.30lbs (65kgs), ensuring it stays fastened in all conditions.
How do the Firefly lights integrate with the Ultra Fly Pro?
The Ultra Fly Pro features a dedicated port at the back of the helmet for seamless integration with our Firefly lights. This design ensures that the lights are perfectly positioned to maximize visibility without affecting the helmet's aerodynamics or comfort. The magnetic attachment makes it easy to add or remove the lights as needed.
What if I want a front light and turn signals?
The Ultra Fly Pro is designed with a rear Firefly compatible port to maintain its lightweight design. For front lights and turn signals, we recommend pairing the helmet with additional Firefly lights on your bike. This setup offers enhanced visibility and the ability to signal turns effectively, ensuring a safer ride.
How long do the Firefly lights last on a single charge?
The battery life of the Firefly lights varies depending on the mode used. On a full charge, you can expect several hours of continuous use, ensuring you remain visible throughout your rides. For specific battery life details based on different modes, please refer to our Product Specifications on our Firefly page.
Why is the Ultra Fly Pro being released in batches?
To ensure each helmet meets our high standards of quality and innovation, we're producing the Ultra Fly Pro in limited batches. This approach also helps us manage the overwhelming demand more effectively. Stay updated by signing up here.
Why should I replace my helmet every 3-5 years?
Helmets degrade over time due to UV exposure, wear and tear, and improvements in safety technology. Replacing your helmet every 3-5 years ensures you benefit from the latest advancements in protection and materials. For more information on helmet care and replacement, visit this link.

Very good product - but not perfect.

Overall a very good product. Light, well made helmet. Lights very bright and easy to connect with nice charging cradle. Like the magnet clip on helmet strap. Enhancements could include: Rubber strap to attach light mount to bike not included. Some improvement to app. Garmin widget to change light blink/status. Include replacement helmet padding.

Solid build; error in manual; 7 day ship to Canada

Got ultra fly pro + firefly mini bundle. Solid helmet build, love the moisture wicking of the inside, and the overall design and build quality. Before this the only limos product I had owned was the fireflies even though I’ve been following this company and their campaigns for years. Now a proud owner. The grey is nicer in person and as a good compromise between white and black.

Shipping said it would take up to 7 weeks to reach Canada but it arrived in 7 days.

The instructions for the firefly mini manual calls the slim adaptor the slim padding on the blow-up diagram page of all the included parts. The package as well as what’s in the box photos on the product page has/shows the TSM silicone padding and the M screws, but those who don’t own the TSM mount will likely be confused by what this is at it is nowhere to be found in the manual. Likely the manual was printed before they decided to include or make the TSM adapter/padding.

Painful

Fine helmet, however on longer rides the tightening mechanism at the back can become painful. It is quite a narrow “belt” that gives a pressure point, even if relatively loose. It would benefit from making the part under the knob wider and softer. Probably going to have to buy a different helmet and sell my fireflies as it is too uncomfortable
