Unleash Pure Speed & Control: The ALPHA 29’er & new geronimo downhill ERW MTB Tire

Tired of wasted energy, flat tires, and unpredictable grip? Introducing the “Alpha 29’er” and our new vacuum pressure “Geronimo” downhill MTB tire super supple to the terrain, engineered to transform your ride with cutting-edge Energy Return Wheel (ERW) technology, delivering unparalleled speed and stability. Forget air pressure; our patented system uses vacuum bellows and energy-returning elastomers, creating a “spring-loaded” wheel that absorbs impacts and propels you forward off bumps and high impact landings.
Key Features & Benefits:
  • Explosive Energy Return: Internal vacuum bellows store and release energy with every rotation, equal and opposite actions and reactions occur in real time 180 degrees across the inner and outer diameter of hoop / wheel interactions. Reducing rolling resistance and converting bumps into forward momentum for faster climbs and sustained speed.
  • Anti-Bounce Ride Quality: Experience a “glued-to-the-trail” feel. Our design eliminates the harsh bounce of traditional tires, keeping your tread planted for superior traction and control on technical descents.
  • Puncture-Proof Performance: Go deeper, ride harder. Explore the less traveled terrain. Say goodbye to flats, slow leaks, and mid-ride repairs with ERW robust, airless construction.
  • Lightweight & Efficient: A composite hoop and advanced materials minimize weight. Maximizing reaction speed, drivetrain efficiency, making your efforts count.
Who’s it for? Aggressive trail riders, enduro racers, and E-MTB users seeking a technological leap in speed, efficiency, and consistent performance without the hassle of air pressure.
Stop wasting energy, start returning it. Upgrade to ERW and feel the future of mountain biking.

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.
