and where have u seen me writing in Russian letters or using Russian words? everyone can misspell...anyway if u got what i mean then job is done...

Ex GF was studying Russian at the U of Oregon ..
passed thru some of eastern europe in the early 90's
So Pivo ! entered my mind :beer:

Что это вы мне сказали? ;)

zabei..... :)

:) lol piva is cool....i miss real Guinness when i used to be in London..

so what u think guys i am planing to change my one wheeled trailer to double wheel...am i making mistake?

You're making a mistake if you don't DECIDE what you want. Heck, you made the mistake when you built the trailer without regard for how it'd attach.

At this stage of the game, you have a frame that looks like it is well suited to a single wheel trailer and you have the wheel and axle all assembled. If you look at most bike trailers, you will see that the majority of single wheel trailers are long and fairly narrow. If you look at most double wheel trailers, they appear to have more square shaped frames and the wheels are spaced fairly far apart.

if you just put 2 wheels on either side of the existing rear axle that you have on your trailer, they will still be fairly close together and I worry that it would not be the most stable especially when you put a suitcase on it going around turns. Single wheel trailers rely on the bike to keep them stable which is no problem. Double wheel trailers rely on the width of the axle and how far apart the wheels are spaced. The closer the rear wheels are placed, the less stable it will be. The taller or wider the load placed on a trailer will make it that much more unstable.

So to quote a saying, "don't reinvent the wheel". You have a single wheel trailer frame that looks decent enough. Stick with it and build an attachment frame like this:

ok...i am very sorry that i have not read ur post bobotech earlier...but what i meant buy new trailer is...i am going to build new frame...and going to buy new wheel...i also bought burley hitch and security cord http://www.amazon.com/Burley-Bicycle...0113933&sr=8-4
http://www.amazon.com/Burley-Design-...0113933&sr=8-7
so my question was...is one wheel trailer better or two wheel will be much easier? i think two wheel will be more stable+ when u have two wheel trailer u have less pressure on rear wheel of bike....i have problesm..since i am planning to put wheel on the sides...i can not find a one sided hub(dont know how to explain) how to attach wheels ?

well in the world where Napoleon Bonaparte made mistake i think me an usual guy can afford some :)

by seeking approval here? ... probably ... :lol:

ur comment regarding my concern would be much helpful for me...

A two wheel trailer is going to be more stable and easier to ride in that respect. However a single wheel trailer is going to be a fair amount faster. Think about it, there is much less weight involved with a single wheel trailer. Then there is only 1 wheel, half as much friction as there would be with a 2 wheel trailer.

So 2 wheel trailer=more stable and able to handle larger more unstable loads but weighs quite a bit more and has more rolling resistance.

A 1 wheel trailer=lighter and much less rolling resistance which means much faster however it would be best to use lighter loads and less wide loads.

fact is i never saw guys traveling with two wheel trailer.....and two wheels look uglier..but for my bike two wheel is much better

guys do u have any idea how to install (or which) hub to a trailer?

If you are doing all this building a 2 wheeled trailer it's really more cost effective to buy a good used one strip it down and add to the existing frame as you see fit for your needs.
I bought a new Schwinn Mark II for around $140 remove the cover and use the frame as is.
I have one for the grand kids and have put 160 lbs. in it and rode great.
You don't need to worry about all the stuff like hubs, wheels hitch as it's done already for you, you have a base to work with at much less than it would cost to build one.

You have already bought $32+ worth of stuff you could have made if you are really building the trailer?

problem is that if i want to buy something not ordinary (trailer is not ordinary in my country)...i wont find it locally...so only option i have is to order from Internet...well to buy trailer online even used will cost me only transportation more then 100$ + i have to declare to tax over 150$ products....thats reason i am building custom..i have figured out everything exept the problem regarding wheels i have mentioned...i am planning to attach my trailer to bicycle with thing i bought (check links above) and i am thinking to use bungee cord for attaching suitcase to trailer...well only problem is i dont know how to attach wheels...is there any hub with only one side working....????is there any brindge i could use to mount hubs?

Here is a link to the Burley site that shows the quick release you can use with a 16" or 20" wheel. That way you would need the right Internal Diameter dimension hollow tube welded to your frame and this quick release would secure the wheel to your trailer.

This way you would not have a whole axle... That's how their trailers have the wheels attached.

If I were you I would write to Burley customer service... I did that for one of my trailers and they were very helpfull! I made one of their older trailers change into a jogger. They might be able to work something out for you.

Hope this helps!

how the second side fixes?

You would need either to have a hollow tube to go the width of the trailer or you could have 2 hollow tubes, 1 on each side. As long as the 2 would be lined up with each other and perpendicular to the side of the trailer. If you want me to I could take some pictures of my Burley trailer to show you what I mean. Let me know...

It's almost sounding like a one wheeled one would be easier to build. I suppose if you had a couple of old bike frames you could use the rear triangles as the outsides of the trailer and if you lined up the dropouts right (assuming they're the same size, you could weld some sort of bed between them, and use that as wheel attachments.

thanks for advice..i am planning to complete in a similar way.....do u think one wheeled is better or two wheeled?

I think 2 wheeled is more stable, but one wheeled might be easier to build as it'd avoid the issue of getting the wheels aligned.
