    I did put the large Plastic box on the rack on the back on my bike.

    It will releive my back of carrying back-pack weight, but now the bike has
    a definite wobble at low speeds, and clunks when I go over bumps...:taz:

    Even these two are worth the trade off against getting a bad back.
    Question is, how to stabilise an unstable object ?

    Its about a foot longer than the end of the back wheel.

    I'll take some pics sometime.

    You might bolt a couple of struts sideways across the rack. then bolt the box to the struts. Should be stable enough.

    may be smart thinking

    may be smart thinking will_start

    protecting your back -- a good thing
    the price later for not paying attention may be -- much pain
    and back pain is something no one wants to have
    seems that many of us older guys have back problems

    I loaded my backpack to the hilt a little while back
    about half way through my ride my back locked up in pain

    not a good sign on that back thing !!!

    my three legged dog and pics of the box


    ok, I promised pics here they are.

    note red/brown three legged dog
    name of bronze.

    he wouldn't move off his bed, so I just
    includ him in the picture taking process.

    BG: U sugguested struts.
    Which really got me thinking
    of making some out of wood.
    I have lotsa wood.

    I have since discovered this box
    creaks a heap when riding.

    I rode with head-phones the other day.
    I was thinking of putting foam padding under
    the box.

    But That means removing about 20 cable ties tho,
    and re-doing it all.

    Which would be worth it, but a pain...:taz::hammer:

    Either that or wear head-phones against the carpy noise.

    That's a good practical load carrier.

    But I wonder why it's so far back. Looks like some un-used space in front of it.

    And you probably want to take off at least some of those zip ties. The ones holding the rack to the bike, for example. That's trouble just waiting to happen. :(

    But I like the idea. I've always maintained that if it's going to be real transportation (as opposed to just a novelty), then it must be able to carry a pretty fair amount of cargo.

    I moved it back so it wouldn't hit me in the rear-end when riding.
    If you put it too close, then you can end up having a scratched back.

    ...and I know you are joking about the zip ties, they're the only thing
    holding it on.

    I was coming up with Designs last night for the struts, and where best
    to place them. The Rattling is really the thing that needs fixing.
    I also need a way to make the load inside not rattle around.
    I put a loaf of bread in there, and the tag came undone,
    and bread ended up strewn around the box...

    Still, its better than having a heavy back-pack on.
    Not bad for $20 for the Rack.

    The wood also acts as a Mud/Water guard as well.

    Well, I've found that when you have a couple spare inner tubes, rain coat & pants, small tool sack, etc., (not too mention a bit of rope, tie-down straps, bungee cords.....) these things tend to make a "bed" that the other cargo rests on. Then rattling is not a big deal.

    And you're right about a rack with some size protecting you from road water. You can even live without a fender.

    BGW: if you see the pic Central Close, there's a gap I intend to fill with Wood.
    I was even thinking of adding wood along the side, but am going to wait for a rainy day
    test, to see how it goes as is.

    The trouble I get is when I have nothing to carry, then things like bike lock and tools
    rattle like a sheet of iron in a strong wind.
  9. heres a better way to carry stuff. $4 x 2 for the black plastic trash cans,bolts and ties to hold them on.
    they hold 2 2-liter soda bottles in each one or groceries. will hold atleast 20lbs+ in each one.

    I like that idea better.
    Lower centre of gravity, and probably no rattle.
    And probably no wobble at low speed,
    as there's no torque going around the wheel.

    I was using what I had available tho.

    Nice idea, I may try it on my next setup.
  11. i divide my load equally in the two plastic bins and there is no wobble at any speed even at 35mph. i did replace my kickstand with a adjustable one because the one that came with the bike did not like to hold bike up.

    I have a normal peddle bike, was thinking of putting something simiilar.
    One thing, could you spell out how you did it ?

    What components or Parts did you use ?
    How did you assemble it ?

  13. parts list: 2 plastic trash cans(size and color your choice), 1 roll of metal chimney strapping or muffler strapping(it comes in a roll its metal 1/2"w with many holes along it,
    nuts and bolts,plastic ties.you can subsitute large metal L brackets instead of the strapping if you want to.
    i used 2 lengths of 12" strapping(1 for frontside of rack/1 for rearside of rack)
    they are bolted to rack with 1 bolt each strap in middle of rack.
    both straps are bolted to each basket(2 bolts per basket)
    i made a small hole in baskets on frame side close to bottom of basket nearest frame and plastic tied the side of basket to bike frame.

    Nice description,

    I found the attached which I used somewhere else here as well.
    This is what the rack looked like before Large Plastic Box find & install.
    (it appeared from under my house).

    The wood "plate" works really well as a mud-guard.
    I rode the new setup in medium rain, and didn't get wet between my back and knees at all.
    IE my Rump, Bum, Rse, posterior or rear-end. stayed dry.
    Whereas, the front of my legs, chest and arms got soaked.

    I've made a triangular wood spacer for the middle bit.
    Shown in close_central.jpg above.
    You have good mud-guards in your pics.
    My bike has no front one.

  15. thats cool ,it could hold your lunch or some tools.

    Yeah, but not much else. I need to carry shopping, wetsuits, clothes,
    spare tools, etc. I am over the wobble's already.
    When I put a bit of weight in it, the low speed wobble could
    lead to a crash given the wrong conditions...:helmet:

    It doesn't hold that much but I looked all over to find a hard locking trunk that would make my bike look like a scooter and loved it! You can't see it in the picture but the one I had had a charcoal metallic colored lid with cool red reflector inserts and the bottom was silver which I'd painted black to match my bike. With a pair of rear view mirrors and the trunk the motobike looks like a real cool scooter for $25 bucks.

  18. my rear side saddle baskets work great,the load is divided evenly on both sides.
    but there is some added noise from having the baskets on bike,maybe some rubber or padding on basket mounts might help.

    if i need more room i could add a trunk between the baskets on rack,now that would be some real storage.

    Hi Will.
    I thought of giving you my idea of carting stuff around as it's
    been working for me since ever I started motored biking,some four
    months back. It is a bit more pricier but worth every penny.
    As you know there are kid bike trailers, variously priced, I went for
    Wall-Mart " IN STEP " brand, the cheapest,which has metal bearings on wheels,
    for $80 odd, put the ply-wood floor in it,
    removed all unnecessary straps, with a piece of foam camping matt
    on ply-wood for suspension, and mud guards, as wheels rub on the canvas when loaded, and you can carry up to 100 lbs on it and as it
    is completely separate, there is no wobble or rattle.
    And still have a milk size crate on the bike rack with all the tools and parts
    in case I'd brake down.
    You may worry about the speed limitations for the trailer but it is only
    when you carry kids in it, it takes speed up to 25mph no worries,
    so I hope it'll give you an idea.Regards.
    Sorry mate, I didn't realise you're in oz so you don't have a - Wall-Mart - but any kid
    trailer would do!!!

    I tried the same basic idea with a milk crate it is too high and affects the center of gravity on my bike .
    Really squirrelly ride.

    You missed the dog in your last central close picture LOL
