    Anyone use a Brompton with a trailer?

    Just curious, I was guessing a folding bike + folding trailer would be an interesting idea.

    I've seen folding single wheeled trailers with 16" wheels allowing a bit of commonality with the spares.

    just curious.

    4720720580_b6ddd4430f_b.jpg I don`t have a brompton but the other folders do fine with a trailer.I like the single wheel one that also folds flat,attaches to the rear quick release,or axel.Action bent recumbent site for pictures on line.It also uses bob nutz and fits to any hub geared bike,and fits in its own bag.I only have a picture of the 2 wheeled one.

    I do..
    Carry Freedom City is a great companion trailer , for a Brompton.

    not only can you tow the trailer behind the bike,
    but you can put the folded up bike on top of the trailer
    and beat feet to catch the train ..

    towing the trailer by hand..

    trailer folds flat within its frame, rolls on 12,5" tires,
    nylon composite, sealed bearings
    sling bag goes in the frame when you are moving..

    Is this folding single wheeled trailer the one that is made in Australia? Got a name and web link? Thanks.

    That is one of my potential game plans

    Still trying to figure out how to get a Brompton P type full accessorized in a B-Pod and keep the whole package under 50# to meet airline regs. Might have to give up on that one and just ride the train more...

    Two of my concerns are stress on the frame, and proper ground clearance (since most single wheeled trailers are made for 20"-27" wheels)

    When I initially bought my Brommie from 2+2 in Cologne, Germany, I was told I could comfortably tow my toddler in a Chariot trailer. I did that for several months. Then I noticed the hinge was starting to get considerable play in it. Took it back to the shop and suddenly they changed their tune saying that such a use was not recommended. Don't get me wrong, both the Brommie and the Chariot are great products, I just wouldn't use them together.

    I have a Brompton and a Radical Designs Cyclone trailer. Before purchase I liked the idea of the freedom, used it a few times and didn't like the ride, the rear suspension and the trailer just produced an annoying yawing effect and I only now use the trailer for short infrequent trips and restrict myself to the Bromptons massive front luggage system and spill-over to the rack.

    I got a long and a short towbar to connect to large and small bikes, attaches to the left side of the frame at the drop-outs.

    I'm ok to selling my trailer, currently it is San Francisco.

    I've seen folding single wheeled trailers with 16" wheels allowing a bit of commonality with the spares.
    NB , BoB and current Burly Nomad,
    & square tube flat bed post brand name purchase after CoOp closed,
    is a different 16" wheel
    it's not the same 349 , as Brompton, It's a 305

    Single wheel BoB needs a special axle nut, for the tow fork.
    may not work with the 2 part setup that holds the chain tensioner on..



    Now, A Bike Friday NWT, etc, and a Burly Co Op made flat bed trailer
    Do share the 406 tire size.

    a bigger trailer , I can store the folded up Carry freedom City inside the Flatbed,
    and pop its wheels off, to go in the closet.

    I built my own trailer which couples to the rear axle on the left side (not the drive side). It's not great, but it gets me out of a fix when I need to carry biggish stuff up to 20Kg. The wheels as 120mm hard skate/scooter wheels and the coupling is airline snapfit connection with the shortest possible length of airline hose to give flexibility whilst minimising back forth lurch. I don't use it often, as I'm concerned that it will cause undue wear on the rear triangle bushes. I was advised not to couple there by the owner of the business that I bought the bike from. I did it anyway as it was easy to build a neat coupling. If you intend to do a fair amount of heavy towing, like 4 or five times a week with 15-20Kg, I'd say get something which would couple to the main frame, either on the seat post or somewhere near the seat post clamp. I'm not aware of anything like this on the market. I did a lot of trawling on the web looking for something like a seatpost clamp with a hinge and toggle which would go around the seat post and attach quickly, but drew a blank; another reason why I went for the rear axle coupling.

    The critical things with trailers are: low rolling resistance with largish wheels that are generally axled under the load CoG; a coupling which gives the degrees of freedom to handle roll, pitch and yaw, but does not allow any lateral relative movement between the bike and trailer along the line of the bike. Any of the latter and the trailer will lurch back and forth when you pedal. This makes riding surprisingly hard work with a load of 10Kg or more. The best couplings I've seen are the ball type or the Weber UJ type, but these are both rear axle mounts.

    Pictures ,,^^^. SVP..

    i have the Hitch for the Carry Freedom City trailer on the left end of my
    Brompton.

    Those load a sling attached bag , hangs in the squar-ish frame, to lower the CofG.
    bag out, wheels fold into that 'square', to pack the trailer flat.

    looks like action bent domain name payments stopped.
    Redirect suggests, its available to use by someone else.

    My folder is one of my favorite tow vehicles as the gearing is ideal... I have two trailers that I use depending on need.

    i use a trailer behind both my Brompton and other (20") folders. Not yet on the Dahon Curve but it is going to happend soon. I have one small Carry Freedom flatbed folding trailer and a homemade copy of the big one.

    Last summer we made Bike Friday- type trailers and used on holyday.

    Brompton's work just fine for trailering!

    There is one thing that you need to look out for when braking with a heavy load in the trailer. If you use the front brake hard (like in a panic stop) the trailer wants to push the rear triangle 'under the bike' at the hinge. There are two simple ways to deal with this... Use the rear brake primarily with a loaded trailer, and make sure the bike's rear hinge lock doohickey is engaged.

    Other than that, I find Bromton's handle very well with a trailer. I regularly used mine to haul 100 lbs of kids + shopping around.

    Travoy Trailer

    I have a Burley Travoy trailer that I've used with my Brompton, and so far, I'm pleased. First use was picking up a load of household items at Ikea Brooklyn and cycling back to northern Manhattan by way of the Brooklyn Bridge. There was plenty of maneuvering through city streets, potholes, and the like, and the bike + trailer handled it fine. I've used it since for groceries, and it's been good. The Travoy seems specially made for the tight turning that urban cycling requires.

    I'm even thinking of using it for cycle touring where my wife and I carry our front Brompton bags, and I'd add the trailer to carry our camping gear.
