SHARK WHEEL FLEX
Front caster for Low rolling resistance, Energy efficiency, and eXploration
Summary
Shark Wheel front casters revolutionize wheelchair performance with their distinct twin-caster design. Unlike traditional wheels, they minimize rolling resistance, making propulsion smoother and more energy-efficient. Their exceptional swivel-ability ensures effortless turning, enhancing maneuverability in tight spaces.
The innovative design excels at obstacle avoidance, allowing users to navigate cracks, debris and uneven surfaces with ease, offering unmatched multi-terrain versatility. Whether on pavement, grass, or gravel, Shark Wheel casters provide a reliable and comfortable experience, empowering wheelchair users with improved mobility and confidence in diverse environments.
Advantages
Shark Wheel has reinvented the wheel to help wheelchair users improve:
- Rolling Resistance
- Swivel-Ability
- Obstacle Avoidance
- Multi-Terrain Use
- Going Over Cracks, Uneven Pavement, Debris
Trust Shark Wheel Performance
Shark Wheel technology is used by Fortune 500 companies, industry leaders, Bridgestone-Firestone, Samsonite, Harley Davidson, Spyder, the US Military and many others.
Shark Wheel sells industry-leading wheels ranging from skateboarding (14 international competition wins and a Best Seller Badge on Amazon) all the way to agriculture wheels (Top 10 New Products at the World Ag Expo)
Scientific Testing
- Up to 57% Less Rolling Resistance
- Improved Obstacle Avoidance
- 15% Greater Rebound
Testing Equipment
Tests were performed and the testing rig (seen above) was designed and constructed by a team at the Mechanical Engineering Department at San Diego University.
Conclusion Test I
At a load of 30lbs the Shark Wheel demonstrated an average of 35.52% less rolling resistance at speeds ranging from 0-650rpms (approx. 15.5mph).
When loaded to 45lbs (per wheel) the Shark Wheel demonstrated 60.92% less rolling resistance.
Rolling resistance, also called rolling friction, is an important factor in many industries.
In caster Keep Roll tests, the Shark Wheel twin caster improved rolling resistance by 57%
Test II - Conducted by Major Wheel Manufacturer
Another scientific test done by the largest skateboard wheel manufacturer in the world. They compared Shark Wheel to the leading wheels in the market in an apples-to-apples test. Same diameter, same durometer (hardness), same material. 15% greater rebound.
Additional Testing
In separate testing at a Canadian test facility, the Shark Wheel exhibited a longevity/wear advantage.
Tests performed by the German tv show, Galileo (similar to the Discovery Channel), found advantages in rolling resistance and off-road performance.
Most recently, our material handling industry partner (pallet jacks, forklifts), completed 3 years of scientific testing and customer acceptance testing with a Fortune 50 company. Scientific testing showed a wear advantage.
Nature
The wheel mirrors Nature. Everything in Nature alternates. The way fish and sharks swim, the way radio waves move, the way planets move around the Sun and even how humans walk with an alternating gait. Alternating motions Nature's preferred form of motion.
The name Shark Wheel comes from the shape of actual shark jaws. They are a near perfect match:
