Unleash Pure Speed: The ERW ALPHA 29’er & GERONIMO Downhill

Stop Wasting Energy. Start Returning It.
Are you tired of “energy-suck” from soft tires, the heartbreak of mid-run flats, and the unpredictable bounce of traditional air-filled rubber?
Introducing the ALPHA 29’er and the all-new GERONIMO Downhill tire. This isn’t just a tire—it’s a revolutionary suspension and propulsion system for your bike. Powered by 25 years of R&D, the Energy Return Wheel (ERW) is here to transform your ride.
The ERW Advantage: Physics on Your Side
Forget air pressure. Our patented Vacuum Bellows and Energy-Returning Elastomers create a “spring-loaded” effect. While traditional tires deform and waste energy as heat, the ERW captures that impact and fires it back into the trail. Every bump becomes a boost. Every landing becomes a launch.
Why the ALPHA & GERONIMO Change Everything:
  • 🚀 Explosive Momentum: Real-time energy return across the 180° diameter of the hoop turns trail chatter into forward speed.
  • 🧲 The “Glued-To-The-Trail” Feel: Our anti-bounce technology eliminates the harsh “rebound” of pneumatic tires. Your tread stays planted, providing surgical precision on technical descents.
  • 🛡️ Zero Flats. Zero Downtime: Navigate jagged rock gardens and “unrideable” lines with total confidence. No air means no leaks, no pinches, and no repairs. Ever.
  • ⚡ E-MTB Optimized: Increase your battery range and motor efficiency by up to 22%. It’s the ultimate upgrade for high-torque electric setups.
The Tech Breakdown 🛠️⚡
🔄 Real-Time Energy Loop: 180° opposite reaction forces turn every vertical hit into horizontal speed. 📈
🌪️ Vacuum Bellows: Patented internal chambers store impact energy like a battery and release it instantly. 🔋
🚫 Anti-Bounce Tech: Eliminates the “pogo-stick” effect of air, keeping your rubber on the dirt for maximum grip. 📉
💎 Composite Hoop: Aerospace-grade materials minimize rotating mass for lightning-fast acceleration. 🏎️
🛠️ Maintenance-Free: No pumps, no gauges, no sealant, no stress. Just grab your bike and shred. 🚵‍♂️
🌍 Terrain Adaptive: The 45 Shore Hardness tread “melts” over obstacles while the internal skeleton maintains high-speed stability. 🏔️
Who Is This For?
The Aggressive Trail Rider who wants more speed with less effort.
The Enduro/DH Racer looking for the ultimate competitive edge in reliability.
The E-MTB Power User demanding maximum drivetrain efficiency and range.
The future of mountain biking isn’t air—it’s energy return.

Cherish Each Moment

This isn’t just a new tire; it’s a fundamental upgrade to how you experience the trail. Feel the difference on your next climb and in every corner. Stop wasting energy and start returning it to the trail.” 

Amazing!

Solid grip in wet and dry conditions. Zero maintenance and 100% flat prevention. Downhill run, these are a game-changer. I’m extremely happy because I spend more time riding and zero-time fixing flats. Would definitely recommend for worry-free trail fun.”

Wow!

 I was skeptical about airless tires, but the ride quality is fantastic. The handling is incredibly responsive, and they just glide over rough surfaces and small debris that would usually jar my bike. The anti-bounce technology really works, providing great stability and control, even at higher speeds. It feels fast and remarkably smooth – a huge improvement over my previous pneumatic tires. Plus, the peace of mind from never worrying about a flat is priceless!”

Best in Town!

“If you are tired of getting flats on your daily commute or trail rides, the Energy Return Wheel is for you! I installed these years ago and have not had to worry about a single puncture since. The durability is fantastic; they hold up well against road debris and rough patches without any issues. The ride is noticeably more precise than my old air tires, which took no time getting used to, the peace of mind knowing I will never get a flat is worth almost any price. For hardcore mountain biking on very technical terrain, ERW exclusive psi. to the surface carves your path like a razor.
