Looking at making/Buying one..
So far "single wheel today" etc
Unigo
Freebird
Homemade from pw80 frame ....any links appreciated

Rego requirements dictate that the trailer and hitch must be made by commercial manufacturer.
The dont make the Dauntless Uni-Trak anymore.......

Hey Mod's , move if you want.....

I already tow a two-wheel trailer (with a solo) but have started on the design of a homebuilt single-wheeler. Incidentally, a single-wheeler works well with solos and leaning sidecars (or, the leaning tug really).

Frame (only) with trailing arm, or quarter-elliptic, suspension. Lighting, plate, mudguard, & cargo box NOT shown.

I prefer the vertical pivot of a universal joint (if in use) to be attached to the tow bike. This keeps the trailer upright even when its "jacked" near 90° to the bike. (That's not shown in those diagrams, but its just a quick paste-&-draw image.)

In QLD there is a registration requirement that the rear trailer lighting should be as w-i-d-e as the rear lighting on the tow bike.

Incidentally, Bandicoot Trailers have shown a Monocoot image on their website for a couple of years.

Oz Nutter · 04-17-2010, 07:36 PM

Bandicoot have abandoned plans to produce the Monocoot, citing rego difficulties across the states....

What you are working on is great,(if only in early stages)
I would prefer to buy from Aussie builder as Freight from O/seas kills the economics of the purchase....

Anyone know if there is a formula to calculate the maximum length of a single wheel trailer in relation to the wheelbase of the tow bike?

I'd like to build a trailer that can haul a mountain bike or surfboard. Kinda like a yakima rack n roll trailer. But obviously with a single wheel and lower wheelbase.

And on that note has anyone towed the rack and roll with their bike?

Cheers

I would love a lightweight trailer as well. If you do build it keep us updated how it goes.

Along with URALS i allso sell enfields. enfield brings in a COZY brand side car,
they had some COZY one wheel trailors. I don't know if there still aviable but
you could find a picture i'm shure.

For trailers, the longer the better.

However if you have to maneuver in tight places, shorter is better.

You make the comprise.

Looks like Raceway can get them. Go all the way to the bottom of the page.

That seems to be a pricey trailer . . . for one that's fairly basic in structure, and material.

Even bicycles are used for surfboard transport:

Just take notice that a Singlewheeler (and its load) has to be balanced against various on-road factors which can include crosswinds. It should be under consideration that the load onboard a singlewheel trailer is partly carried by the REAR WHEEL of the tow bike, plus the trailer's own wheel . . . . with various percentage divisions like 15/85, 20/80, or 30/70 etc.

Its worthwhile looking at how others have designed theirs- ThirdWheel, UniGo, TourMAX, N-Line, Cyclope, La Globe Trotter, and others.

I agree that the rack and roll trailers are way too much money. But I really like the design. So I'll build my own someday.

I'll take a look at some of those brands you mentioned and see if I can come up with any good ideas.

Midnightventure · 04-26-2010, 06:08 PM

I built one using the front wheel from a small dirt bike. I originally used a large cooler for a box. Got a lot of looks going down the highway. The cooler wasted to much space because the walls were so thick so I built a box out of plywood.
Here is a link to some pictures of the build process. I had read that Uni-go had some problems because their jig got out of square so I tried to keep everything within .030 in tolerance for parallel.

It pulls so good that I forget its back there sometimes. My wife goes with me a lot more now.

vortexau · 04-27-2010, 05:24 AM

About the best value for boxes I've found is in the stuff called Garden or Deck Boxes. I'm using a 400lt box on my two-wheeler and this type of container is more than half the price of a car Roof Topper in Oz.

The very last one of these I bought is a 90lt capacity box, and this may be suitable for attachment to the single-wheeler frame. I'd just use the holes made to fit castor wheels on the base. These boxes can slot together so a second box could double that to 180lt storage space.

According to "Ali-Lite.com.au" they are working on some sort of single wheeled trailer...
