    Rowheels available early next year!

    Hi everyone. I'm an engineer and a fellow SCI (C5-6). I invented Rowheels and have been working hard to bring them to market. In the next couple of months the Rowheels beta prototypes will go through clinician and user testing as well as durability testing through a RESNA certified lab. After that we will make design changes based on test result and user feedback and start with the commercial version.

    So we are far enough along where I would like to start getting some initial feedback, impressions and/or constructive criticism from the user community.
    Below are links to the website so have a look and tell me what you think. Any and all feedback will be greatly appreciated.

    I really like the idea of pulling backwards instead of pushing forward...you need a video of a user actually DOING it as it is hard to imagine.

    Are you going to be at Atlanta event? which one?

      Congrats on your invention, award and progress. The weight on the site says 5 to 6 pounds that is for both wheels? Also a video of someone with these on a chair in use would be great....Do you have a target price for a set of these?

        That's a very interesting concept. The sorts of things I thought about while watching the video were, in no particular order:

        1) simplicity is what I like so there is less to go wrong. Is the wheel simple? Can grit or dirt bugger the system?
        2) robustness - wheels and chairs take a lot of work eg going up and down kerbs - so the wheel needs be proven to be as robust as eg Spinergy
        3) price - for me to consider purchasing the wheel it will either need pricing to a similar level as a standard wheel or I will need to have damaged my shoulders in order to pay a premium to get rid of the pain.

        It looks a good idea and I wish you success.

          I can't envision how this works. I'd need to see a video.

              5-6 lbs each.

              No target price yet.

                I saw that video I think you need someone in a chair demonstrating them. So you push forward to go backward? or do you flip a lever?

                Thanks

                  Interesting idea.
                  Why does the demonstrator adjust the hub?
                  How do I get to try they? I'm in Florida. I could beat them up for you.

                    Can i get a shout out!

                    Nice model of a TiLite ZRa! Bet you got it from GRABCAD! How about a thank you to the person who created the model!

                    Thanks

                      i would be concerned that pulling backwards to go forwards would involve pulling my shoulders away from the backrest. that is how i get into reverse with my wijit, and if i try to back up an incline, go over the edge of a rug or even bump into a tiny obstacle, i fall forwards towards my knees. i dont have the working ab muscles i need to counter the pulling force - right now if i put my brakes on and pull on my tires ill quickly fold over. maybe with abs it would work - but pushing to go forwards (ie. moving the wheel the same direction as travel) is more intuitive, and a major reason i picked the wijit over the nordigo.

                        Thanks Pete.
                        It is a relatively simply mechanism. It has seals to limit dirt, dust and water from getting in.
                        We are trying to walk a fine line between lightweight and robust. The RESNA durability testing we plan on having done will verify that.
                        I am very conscious of the price issues associated with other devices in this category and we are doing everything possible to bring manufacturing costs down so we can offer it at a sensible price.

                          Don't quote me but somewhere between $1,500-$3,000. Hopefully more towards the left but there are still lots of things that could change after testing.

                          When you pull on the hand rim, you go forward and when you push you go backwards. No lever. It's seemless. The dial being turned in the video engages the hill-holding mechanism.
                          So, going from A to B you need 31% less strokes, while traveling 31% farther per full rotation of the hand rim.

                            Yes, I did. I added a couple of minor things but if if it is a problem, I will take them down. We will have actual pics by October. Thanks either way!

                              My thoughts exactly. Another thing I notice is the handrims are spaced out quite far from the tire increasing the overall width a couple inches. And, I would imagine safety requirements will ultimately dictate a guard due to counter rotating spokes.

                              Interesting though. Are you able to combine this with multi-speed hubs or they protected by patents (don't see why as it's not much different from the Bendix 2 speed bicycle hubs of the 60's).
