FLY Racing Rayce Sonar Bicycle Helmet | BMX, MTB and Off-Road Cycling
Helmets ship in 7-10 business days
The FLY Racing Rayce Sonar Bicycle Helmet delivers full-face coverage for riders pushing their limits on BMX tracks, mountain bike trails, downhill courses, and dirt jumps. Its lightweight poly-alloy shell, certified EPS liner, and True Functional Ventilation system balance protection, airflow, and comfort for aggressive bicycle riding.
The Rayce Sonar meets CPSC 1203, ASTM F1952-15 for downhill mountain biking, and CE EN 1078:2012/A1:2012 standards. These are bicycle helmet certifications intended for BMX, downhill MTB, trail riding, and recreational off-road cycling.
Popular With E-Moto Riders, but Designed Specifically for BMX, MTB, and Off-Road Cycling
Lightweight Full-Face Performance
The aerodynamic poly-alloy shell helps reduce unnecessary drag and rider fatigue on long climbs, fast descents, and technical terrain. At approximately 930g ±50g, or 2.05 pounds ±0.11 pounds in size Medium, the Rayce Sonar provides full-face bicycle coverage without the weight of a traditional powersports helmet.
True Functional Ventilation
The True Functional Ventilation system moves air through front intake vents, aligned channels inside the EPS liner, and rear exhaust vents. This airflow helps release heat and moisture during intense pedaling, warm-weather trail rides, downhill laps, and BMX sessions.

Fitment

Secure and Comfortable Interior
A padded chin strap and D-ring closure help keep the helmet stable during technical and aggressive riding. The removable liner and cheek pads can be washed after dusty, muddy, or high-temperature rides, helping maintain comfort and freshness through repeated use.
Durable and Serviceable Design
Aluminum visor screws provide durable mounting hardware for rugged trail use. Replacement liners, cheek pads, visors, and compatible hardware are available, allowing riders to refresh worn components and extend the helmet’s useful service life.
Why It Stands Out
The Rayce Sonar combines three recognized bicycle safety standards with a lightweight full-face shell, TFV airflow, washable interior components, and replaceable parts. Its ASTM F1952-15 downhill certification makes it especially valuable for riders who need more coverage than a standard open-face bicycle helmet.
Proper fit is essential to helmet performance. Replace any helmet that has sustained a significant impact, even if exterior damage is not immediately visible.
FLY Racing Rayce helmets are popular with e-moto riders because of their lightweight full-face design, ventilation, comfort, and aggressive styling. However, the Rayce Sonar is designed and engineered specifically for BMX, MTB mountain biking, downhill riding, and off-road cycling.
This is a bicycle-certified helmet that meets CPSC 1203, ASTM F1952-15 for downhill MTB, and CE EN 1078:2012/A1:2012 standards. It is not represented as a DOT or ECE 22.06 motorcycle helmet.
Riders shopping for a Surron, E Ride Pro, SRPNT, Altis Powersports, or other high-performance electric dirt bike helmet should review local helmet requirements and consider a properly fitted DOT or ECE 22.06 certified motorcycle helmet when motorcycle-rated protection is required.
Best For
- Downhill mountain bike riders who need ASTM F1952-15 certified coverage
- BMX and dirt jump riders looking for lightweight full-face protection
- Trail and recreational cyclists who want strong ventilation and washable padding
