Now, about (cough, cough...) 10mm. Yellow inside I tried, but where it should sit the axle is no longer bevelled off. So it's on the outside now. Tried various other permutations including hitch bracket inside dropout, all had issues.

BTW the is a flickr group called "small wheels big loads"

https://www.flickr.com/groups/smallwheels-bigloads/ -- lots of different setups shown...

Tryed to post this earlyer today, had problems wit the connection.

This is the DIY bracket i have used on the white folder (der, not hubgear) for several years. I doubt that your chainstays are "fat" enough to use this system plus the arm of the coaster brake is where you want this thing to be.

I had wanted to build a trailer to haul groceries and other crap but about a year ago I found one that cost less than what I could assemble one for (about $90 IIRC... an Aosom 2 child trailer). It has stood the test of time and still functions beautifully... and it has a nice reliable hitch.

Badmother, I really like that hitch you fabricated... it's another awesome testament to your ingenuity.

Very clever! Is that a seatpost fitting you adapted?


Thanks for the warnings! I rarely use the coaster brake at all, mostly occasional speed modulation and 'hands-free lamppost leaning' at red lights.

Thank you thank you, you have me blushing like a scoolgirl- again..

It is the front part of a ahead stem https://www.sjscycles.co.uk/easton-ea...ack-prod16269/

Cut it approxemately in half (at least if it is a looong one you wanted to replace with a shorter one). The part supposed to hold the handlebar is the part holding the chainstay on my bike. I was lucky that it was a good fit with the oval owersized (alu) chainstay but it could be possible to stuff some pieces of PVC pipe or similar in there on a slimmer chainstay. Been using it for at least three yrs.

A little esoteric point worth mentioning is that the axle nuts on the Nexus are 3/8" 26 tpi, not a size you may necessarily have knocking around in the bits bin, and the standard 'acorn' nut needs far more axle to grip than a flat nut. I'm using the thick lock nut I removed from the innards as a stopgap, obviously not a long-term solution (not least because it needs a 17mm spanner).

Vintage British motorcycle suppliers seem to have plenty, I've ordered a baggie to be on the safe side.

Last year BikeNashbar was blowing out those Easton EA50 stems so I bought 8 of them at $1.99/ea knowing that I'll eventually find a use for them.

They can be used for a lot of different things. I used one to atatch a shifter to the seatpost of a detatchable bike some time back: https://i277.photobucket.com/albums/k.../BMXfolder.jpg

Later on I copyed HGR3inOK`s solution that he used on a Moulton: https://www.flickr.com/photos/77836183@N08/8893498312/ and put the shifter on the handlebar on the two similar red and black bikes.

This is a blury photo of the DIY copy of the Carry Freedom hitch on the same bike:

I`ll try to remember to edit to a better picture.

This is Anton`s fat alu dropouts with the Carry Freedom hitch on a Nexus7 hub and anti rotation washer. Not sure why I did not have the samë problem as the OP (or maybe I did and forgot):

It's a blast

And for supermarket shopping at least, im a convert. Like throwing everything out of the trolley and into the car boot, but easier and faster. Towing 15-20 kg was very smooth and fast. And such a well thought-out trailer too - you don't realise this until you use it, everything is where it should be and just works,

I even managed to tip the bugger - I just forgot it was there and clipped a curb. Good hitch - tip but no flip...

I hope that people are still monitoring this thead as I have purchased the Aosom Flatbed Traveler trailer and have read a number of reviews that tell buyers to purchase different wheels and tubes. Does anyone here have direct experience with the Aosom cargo trailers and recommendations on what wheels and tubes to get as replacements?

Thanks all

Searching the forums I only found this thread mentioning the trailer.

First of all we need a picture.

Picture from Amazon:

Looking at the picture I see knobby tyres. Personally I would not use knobby`s on a trailer, unless you often ride in places where it could slide sideways. For that reason I would buy something with less thread. The trailer is rated for 110 pounds so make sure each tyre can take atleast 60% of that.

Tubes- not sure. I suspect they could work ok with better tyre- that is tyres with some puncture protection. Those tyres in the picture does not have much of that I think (looks like the ones you find on cheap childrens bikes).

Looks like a sensible trailer for the money.

Maybe wait and see what tyres they actually deliver? Knobby tyres look like they might spray up too much dirt and water from the road, and be a bit muckier to store (I'm thinking: easy enough to avoid doggie doo-doos on a bike, less so with two extra wheels...).

The Carry Freedom came with Big Apple copies from a Taiwanese firm, Gumonder. 16" x 2" (ETRTO 305-50) - fat and smooth seems to make sense for trailer tyres.

Not an expensive fix to fit other tyres though, and they ought to last for years. Get ones with a reflex stripe for safety while you're at it.

^ these duly arrived, and they fit more precisely on the axle than the Shimano 'acorn' nuts. So be safe and make sure you have the correct nut for your axle when fitting a hitch bracket (I for one never realised there was such a variety) - other nuts may feel like they fit, but they don't grip...

PIX, PIX, PIX! I often use other nuts than the acorn nuts on Shimano hubs. Do not like them.


Been playing around with trailers prepairing for the holydays. Sucsessfully fitted 12" wheels on the Y fram trailer the other day. Those are taking up less space when traveling. Pix later. Need to make a new frame for a suitcase trailer also.

With 'variety' I meant the different axle threadings and sizes, often worryingly close to one another.

The nuts of course just look like zinc-plated nuts, single chamfered, they grip the axle from the first quarter turn. UK-made from a supplier of fasteners for classic motorbikes. If I'd used these from the get-go I probably could have avoided faffing around removing spacers and the like.

My Carry Freedom is now equipped with a 60l Eurobox with lid and the supplied box quick release, a neat system as the entire load is secured with basically one strap. A second 30l Eurobox fits snug between the larger box and its lid too - so 90l total at 50 cm height if needed.
Euroboxes with the 60 x 40 cm footprint are inexpensive and available in folding/lightweight versions too.

^ good idea! You ought to sell these as aftermarket equipment...

Lighter, and a lower centre of gravity too.

Love my Carry Freedom Y-frame trailer. Towed it much overloaded from Mudgee NSW Australia to Adelaide and then on to Perth. Had an absolute blast and the Moulton towed it like a dream.

The tires are very low profile knobbies, not as bad as one would think. I didn't bother changing them out until I acquired some 'cast-offs' (free) with a street oriented tread. The tubes were fine... I'm not sure why it was suggested to replace them because they have a valve that works and they hold air.

The trailer is working hard for its keep - terrific for oversize things that need to be moved. Already saved several local car trips.



It took a couple of trips to get used to. Since the bike handles like an unladen machine the temptation is to ride as if you weren't carrying anything at all. But you can't ignore the physics of it all - all that stuff has to be moved. After a couple of traffic light starts that ended with my legs screaming, I started taking things a little easier!


Storage space is minimal - you can hang it on the wall:

Yay, well done! Looking good, both trailer and bike!
