    Sure and you could even powder coat them or better yet do a Rhino liner treatment so they don't get stoned chipped all to hell by crap thrown up by the back wheel.

    Why do you hate the free market system? :rofl

    Although a lot of C.R.A.P. is crap, these are not bad at all.

    I'm close of finishing the plans for a trailer I'll make and was nice seeing this post.

    I used to race downhill mountain bikes and I've been over 60 mph on dirt and jumps and over 80 mph being pulled by trucks on pavement on my bicycle and the tires holded perfectly

    Also, having the wheel at the fardest point gives you a lot more stability than having it in the middle of the trailer (the longer the wheelbase the better)

    Good idea to have a shock on it but If you can get a progressive and adjustable one would be great so you can adjust it according to the terrain and load.

    And I think the best is to attach the hitch to the bike's rear axle instead of the top of the bike. So it doesnt affect the bike suspension

    Ok.. so those are my thoughts.. now I have a question

    1 or 2 tires on the back??? I still cant make my mind on it. So if any of you guys have tried both please let me know what you think works better

    Hey, some good points but first I have to ask .... 80mph being towed behind a truck :eek1 you're braver than I am :D

    I think I get the point about having the wheel behind the load but that would apply on a one wheel trailer as opposed to a two wheel, right?

    This two wheel is larger but I was impressed by the design and options on carrier size

    Wow! That POD-ium thing is cool!

    I need to replace my small utility trailer soon, too, so I may have to look more into that! I mostly carry kayaks and bikes on it, and the occasional Home Depot or dump run...

    I have been enjoying this thread. I had a Bushtech trailer on 1990 Honda Pacific Coast 800 for camping.
    Just for ideas, go to
    http://store.royalenfieldusa.com/
    and look at the RE trailer.

    Ironic that this got bumped.

    Just last night I was thinking to myself -

    "self, it's time to look into a moto-trailer."

    It ain't pretty, but the mock-up is ready to go to the welding shop...

    Current wheelbase seems to be about 67". The tire clearance is a bit insufficient.

    Looking good :clap

    Are you fabbing if out of aluminum? I guess some of those pieces in steel would be really heavy.

    Hey ag streak, Looks great. Looking at the pin where the trailer articulates, remember to keep your torerances close.005-.010 and make sure to use a pin that is threaded, to be able to increase the hitch pin presure to better stabeleze the trailer. It looks great. I can't wait to see the finished trailer.

    I started thinking about a trailer after imagining what could happen if I strapped my snowboard (sideways.. as a spoiler) on the back of the bike and hit a wind gust at 75 mph! hahahaha

    Oh yeah, all aluminum to keep under my weight targets. My only concern is the pivot points, swingarm and hitch. They may need bushings to prevent force and vibration from enlarging the holes.

    I'm using these...

    [​IMG]

    The tow pivot has a M10 thread up the middle and fixes through your hollow rear axle with spacers to centre it.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:eek:ffice:eek:ffice" /><o:p></o:p>
    <o:p></o:p>
    The &#8220;C&#8221; shaped parts are welded in the end of a &#8220;U&#8221; tube which forms part of the tow bracket around the rear wheel.<o:p></o:p>
    <o:p></o:p>
    The trailer is then simply offered up to and over the tow pins and the collets pushed on and pinned to attach the trailer to the bike J - and no &#8211; it won&#8217;t pull off!!<o:p></o:p>

    What are these called, what are they originally used for, and where do you get 'em?

    Thanks!

    Well, me and the welder didn't "click" I carefully explained what I was after, but he didn't seem to get it. I wanted a quick and dirty prototype, he wanted to maximize his price. He estimated $800 for the work, saying it was a lot of welds.

    I see his point, so I designed another frame with fewer joints and welds. It uses a single tube main frame instead of twin flat-stock main rails. I thought the flat-stock idea was a bonus, but apparently, it causes more hand-work.

    A large-diameter tube would have great stiffness and can be bent to the shape below in minutes on a tube bender (the diagram has angled bends only because they were easier to draw). Then a simple three-piece hinge part for the swingarm pivot and a single hole for the main pivot. Simple.

    The swingarm is conceptually the same.

    The hitch is five easy pieces. Steel rod instead of aluminum wouldn't weigh much more, and can be bent without kinking (I'd still prefer a hollow-tube hitch loop.) The plates that mate to the bike axle could be the ones posted by Ewok.

    Had them made specially for my trailer. The design has been modifed further now. No r-clip. The collet is a bit bigger and housed a push lock to 1. fix it to the bike and 2. make it secure.
