    Strida without pedals as a mobility walking aid?

    Guys you have to trust me now but I found this one today.

    I have a bad balance and each winter I always fall on snowy streets.

    So what are the alternatives. Using a wheeled Walker/Rollator
    or using a Mobility Scooter which are very expensive and need
    some kind of Garage or indoor place for protection from snow
    and theft/vandalism

    Now a rollator does not help much if one have knee pain.
    So I came to think of what they use for children before
    they have the proper balance for a pedal bicycle.

    They use Balance Bikes of different brands. Stryder LikeaBike
    and whatever names these have. Basically a standard Bike
    without the pedals. One can even take out the pedals of
    an ordinary bike for kids and use that one.

    So I looked for grown up versions that is easy to fold
    and can be used at winter and that could be accepted
    indoors at Mall/ShoppingCenters. I found this one.

    You see a standard Chinese? very cheap Rollator I bought one for only
    600SEK and the European versions cost three or five times that price.

    And below the Rollator you see their alternative that they used
    for to test if it is a good alternative to the Rollator/Walker and
    their conclusion is that for some it is the best alternative

    So I wanted to know the name of the company and the Model name.
    To find out the specifications and if it exist in Sweden.

    So I tried out different search keywords and suddenly found this patent.

    http://www.google.com/patents/US20090194142

    A supportive medical walking aid for indoor use
    consisting of two small caster wheels located in-line
    with adjustable, collapsible seat and handle bars.

    Named
    Two-Wheeled In-Line Walker
    by Paul James Zimmerman
    I hope he read this and join us and share how he came up with
    the design I mean this is a Strida without pedals is it not?

    I mean what is the difference? apart from no pedals?

    No drive train, rear caster wheel, different use pattern. May be sufficiently novel to warrant a patent. I am not a legal expert.

    The reason for no drive train is that if you have no pedals not any cranks
    and no chain or shaft or chain or any other such then no need for a drive.

    This is a Laufmachine like the Draisine made by Karl Von Drais mid 1850 or so.

    Caster wheel mention in the patent is most likely of this sort
    http://en.wikipedia.org/wiki/Caster_wheel
    Casters may be fixed to roll along a straight line path, or mounted on a pivot such that the wheel will automatically align itself to the direction of travel.
    Rigid casters

    A basic, rigid caster consists of a wheel mounted to a stationary fork. The orientation of the fork, which is fixed relative to the vehicle, is determined when the caster is mounted to the vehicle. An example of this is the wheels found at the rear of a shopping cart in North America. Rigid casters tend to restrict vehicle motion so that the vehicle travels along a straight line.
    I am no mechanic but if you mount a pivoted caster wheel
    in the end on machine that is supposed to help Elders
    to keep balance then you are in for big trouble.

    So I trust that the writers of the patent refers to a rigid caster wheel.

    Maybe when one buy them they are referred to as caster wheels
    regardless of if they are swivel or rigid? Some four wheel Carts
    at Shopping Malls in USA has the front casters to swivel while the
    rear caster don't swivel so that can explain why they use such
    misleading name convention.

    The rest of the bike looks very much Strida to me.

    So what about the A bike? Could be used? http://www.youtube.com/watch?v=xtXIvKXnnxw

    With quick release pedals instead of foldingpedals you can "walk on it" or ride it.

    I agree, I actually begged to try one out. A friendly Recumbent enthusiast had bought one and I asked him to allow me to use it some 5o yards on the sidewalk to see if I could keep balance and it worked out even better than when I tried to keep balance on a Strida.

    And it us much smaller than a Strida when one step up on a very crowded Bus or Commuter Train that don't allow bikes at rush hours so if one have a A-Bike Bag that completely covers it then I can have it between my legs and be allowed to take it with me which would be hard to do with a big Strida taking up much bigger space even if held close to the body.

    And A-Bike is among the lightest bikes there are?

    But does it really accept my heavy body in the long run? They have shown pictures that it easily break the tube where the strain of tension is the most hard for the material to stand up to.

    Okay the latest model the A-Bike City model has a strengthen tube and bigger wheels that most likely run more smoothly over small bumps so maybe that would hold up better.
    City model has 8" wheels instead of the 6" wheels of the original A-Bike.

    I do feel very temped to buy one and I do have the money but it is my laziness when it comes to changing the the inner tube after a leak I would need to buy one of those "pirated" version that have a solid tire.

    My main need is to use it when there is snow and ice and does that work well for a A-Bike?

    And it does not help me much when I need to buy food? I need something that acts as a Balance bike on the sidewalk so if should not be a regular bike because they are forbidden on sidewalks and it need to be more like a real four wheeled Rollator/Walker when I enter the Mall or ShoppingCenter for to go well with the Security Guard that would throw me out recognizing that the A-Bike is a real bike and not a half rollator.

    But you sure are right. A-bike has many if not all of the features that I want.

    Why I enthusiastically talked about this very similar looking Two Wheeled In-line Walking Aid is that it would more easily get accepted as a crude kind of walker if I could re-arrange so when folded the two wheel would be the other way like on a Cart instead of like a Bike.

    Then I could complement these two wheels with very small swivel casters for indoor usage and these will be hitched to under the seat when I use it as a Balance Bike.

    Balance bikes having no pedal and not drive train and not crank or cogwheel or anything that make it into a real bike hopefully could be allowed on a sidewalk due to it is more like a kick-board and such is not allowed in the street in traffic as I get it.

    But apart from that it felt interesting to get feedback responses on that Zimmerman have done I mean did he came up with this without having have seen or heard about Strida or did he consciously reused the Strida but applying it in another field like "Mobility Aid"

    The bad thing about Strida as a mobility aid is that the seat is way too small to feel okay when one have the feet dangling free. Even when one actually pedal the seat is way too narrow for my taste but that is due to me being very heavy. I would need a much broader seat.

    A-bike= 5,5 kg, kr 1000,-

    I think you need more than one solution for your needs. For shopping and mowing around a mall or similar you nedd to get an electric "rullstol". I would guess that in Sweden you get them from the gow if you need them. Then get a mobility aid of some sort to practice and keep fit. Maybe also a stroller.

    That could be the older one and maybe a used one?
    Or they had a few on Sale?

    the modern one ABike-City has 8" wheels and cost
    in Sweden 3300 about
    http://www.prylfabriken.se/shop/a-bi...pfallbar-cykel

    Sure I can afford that but I doubt that it will be practical
    due to my need to have something when I enter a Shopping Mall
    and they would not like an A-bike to enter their Mall.
    But a Rollator is okay.

    Yes I bought two Rollators and got one for free.

    Strollers I have never heard of unless you have
    children to carry in a Stroller. What did you think of
    could you care to give a link maybe ?

    Sorry, it is me mixing words up. Not stroller, it is Rollator I ment to say! I am not sure if Rollator is the right English name for it, I normally call it a Walker.

    A lot of peopel use a Brompton as a shoppingcart so not sure they would chase you out of the mall. Much easyer with stuff they are used to see as mobilityaid. Did you try to contact the mall and explain the situation? Ask for a written statement to carry that you are allowed in with the bike?

    Yes the naming is confusing. In USA they have walkers without wheels
    and then they had walkers with two wheels and then with four wheels.

    AFAIK all named Walkers or Wheeled Walkers.

    A Swede around the end of the 1970 came up with the Rollator
    and named it in Swedish Rullator and translated to English
    name got to be Rollator then maybe she did not know or
    care about the American name for it.
    Rollatorn uppfanns av Aina Wifalk i slutet av 1970-talet.
    Yes good advice there about having a written statement to show.
    But sadly Swedes can be very formal and rigid about rules. So ...

    Yes I have been thrown out but it is true that some Shop
    owners do accept a folded Brompton. Several have told me that.
