a new system has been developed to eliminate the need of air in bike tires, while still preventing the common
occurrence of punctures, tube replacements, even pressure checks. the ‘energy return wheel’ concept by
colorado-based designer brian russell demonstrates the possibilities of advanced wheel technologies.

instead of air, it uses rubber stretched over a series of carbon nano tube reinforced composite rods to provide 
its cushioning. these rods can be adjusted, changing the tension of the rubber to suit different types of terrain,
improves flexing and recoil cycling. with the intention of reducing weight, a 29er wheel made from carbon
fiber is incorporated. further improvements include the possibilities of implementing a thin sidewall to keep
mud and trail debris out for a more consistent ride.

  • There was already a concept of Michelin, but it is nice to see an application for bikes.

    Diego says:
  • is’nt possible tuning the pressure during the use!

    enk'ox says:
  • Wouldn’t they fill with Mud?

    James says:
  • Great, great idea!
    But:
    -In the video you actually never see a close-up or/and a slow-motion of the tire which could visually confirm (and better explain) his claimed \”energy return\” power;
    -Can you imagine how much junk will be trapped in those holes??

    marvin says:
  • nice idea in the desert! but what about on real dirt tracks? fill up with dirt

    kennyb says:
  • Cool, i want some! What are they like going through water? Like treacle i\’d imagine, i wonder if they become unbalanced when full of mud and stones?

    SJS says:
  • Great idea, for most of all terrains , mud is a minor problem in a city.

    Sal says:
  • no more holes in my tires a great idea!!!

    leo michiels says:
  • Sal, I suppose, this wheel is not for the city. It\’s good idea for warm, dry mountain ride, like author has showed us in video.

    And not for mud and water — wheels will become like a sprinkler of s#it, clay and loam will clog of all the cavity and the wheel will become heavy.

    timaktaev says:
  • finally!!!! i want one! i am tired of my weekly punctured bike tires!!!

    bibo says:
  • bibo, put more pressure next time, 3.5 atmospheres is ok )

    ramon says:
  • hahahaha,
    Cool crabon stuff this. Useful in a hurricane, wind could blow right through them. Snobby, I know you’re gonna be onto this like McFly onto babbleon.

    africantubeless says:
  • Are they MADE in AMERICA? That\’s Important to me.

    Sugano says:
  • What Sugano said, except Canada 4 me…..excellent remark, should be seen more often

    pasha says:
  • For the mud issue they’re thinking of a version with a thin sidewall, basically just a shield. That would work I guess.
    It’s probably a lot lighter than tyres. I would also be interested in a road version?

    Laurence says:
  • The great thing about air in a tyre is the low weight. How much do these weigh?

    NewWheel says:
  • Сбор грязи и камней.

    Vitaliy-10 says:
  • how bout wet snow, mud and small stones and winter climat..?

    kkk scandinavia says:
  • This idea just seems overengineered. The beauty of air filled tires is the ability to adjust the pressure. I run my tires as high as 60 PSI on the road (warm weather). Off-road dirt riding only requires 35 to 40 PSI. Winter riding on the other hand sometimes requires my tires to go as low as 20 to 30 PSI range. I would hate to see these tires filled with thick heavy slush. Seems like the Centrifugal force combined with the possible air cooling effect of lifting the slush off the road surface would lead to a completely frozen 75 pound wheel. Lets see more emphasis on light weight indestructible tire materials.

    BigEd says:
  • To seal off the inside of these wheels are the least of problems. Any lightweight waterrepelling fabric will do!
    The fact that they decrease rolling resistance and totally eliminate punctures will make these a totally welcomed invention.

    jo the biker!!! says:
  • Great idea indeed!

    Bluelarix.com says:
  • Finallyy! A good idea 😀

    PePPoZ79 says:
  • Where can i buy?

    Marcio says:
  • Where can I buy from as I do a lot of mountain bike off road please reply thank you and how much

    Craig says:
  • How much are they and where can I buy them

    Craig says:
  • 40 years ago children bicycles from CCCP has this same conception on wheels. Tyre was made from special rubber…

    peter says:
  • Interessante, mas e o preço fica em quanto?

    saturno4 says:
  • Request – Let me too – Change my Bicycle Wheels with – Energy Return Wheels. Kindly Tell Details of – How to Do That !

    amritananda sandy says:
  • Great concept, the idea is very good , but yes as mentioned by other people up there there will be some issues like :
    – Large stones stuck between the gaps …
    – But my biggest worry is when the tyres wear off … Do you have to replace the entire wheels ? (that will be expensive then)
    …they look great with the gaps, you can actually see the technology, good for urban riding, but you got to have 2 versions then 1 with gaps and the other without gaps for MTB ..so i say close the gaps with a flexible material to element-proof the tyres and make it possible to replace the tyres like on the normal wheels ,
    Great Innovation tho! make it more efficient and i will definitely get a pair ;o)

    Jalen says:
  • Seems like it could have potential to improve tubeless road tires. It would be a great product if it could save the weight and mess of sealant in tubeless.
