    The price is very good. Gosh everything is so much cheaper in USA!

    It is very similar to my own Chinese generic steel-framed uniwheel "Adventure C1". They are very useful for light loads. Rated to 35kg but I find low speed handling poor at anything over about 25kg because you tend to move the bike around a lot under you at low speed.. Gets better at a decent cycling pace though because the bike is kept more steady.

    The premium brand / original USA made B.o.B Yak has a forward sloping headtube which helps stop your steering affecting the load at low speeds and allows a more carefree approach to tight turns. But BoB users crash at high speed because if the load wobbles it turns the fork and that affects the bike like a horrible speed wobble nightmare. (Try mocking it up with bits of cereal box to see)

    The vertical headtube trailers like this one need to be leaned harder into low speed tight turns which is something you will learn to do after the first time it flops over when you tried to park it. But they handle high speeds better. The load above the axle line wobbling doesn't turn the headtube and affect steering.

    Though it is supposedly a foldable trailer I think they only designed it like that so it's much cheaper to ship from China. I have never folded mine and actually replaced the upper q/r bolt with a regular nut and bolt so it is tighter and so there is more room for the box I carry in there. I would love to get it welded up with a couple of extra struts to make it stronger.

    I got a bigger, beefier type of Q/R skewer with mine. I bought an extra one "M-Wave Q/R skewer" for the beater bike so I can switch bikes faster, and it looked like the one that comes with the trailer in your link, looks like it won't give as much of a secure connection with the bike, but so far I haven't bent it riding carefully with up to three 20 litre bags of compost!

    I've no springs on the rear of mine. I'm not sure how much use undamped spring suspension is anyway or what load the springs are still active with. I suspect they will be fully compressed when the trailer is loaded up. Anyway wouldn't they twist, or try to twist and put an odd strain on the rear wheel etc.? You get a better aluminium fender with the (my) rigid unsprung trailer so it keeps the spray off your load and the rider behind better than this one.

    I'm not sure what tyre is on that.. Hipefully a slick. Mine came with a Kenda knobby tyre which is usable but I replaced with a Schwalbe 1.75" Road Cruiser that has a lot less resistance because it is smooth even though the tyre is actually thicker, higher max pressure, but the air volume is about the same.
    My trailer with no springs but lots of thick, heavy retroreflective tape all over it weighs about 18lbs / 8.5kg. I made a lightweight rolltop bag to go inside.

    Single wheel is easier to avoid potholes, bumps and dog poop. But it can tip over if you don't lean the bike into tight turns. It should be used with a rear (bike) axle kick stand as in the pics there or it can be a pain to park up.

    Inverted, it makes a handy table for camping. With some box steel and welding it could also be used to sit on. :)

    It is rated at 88 pound max cargo which is close to what yours is rated at.

    Yep it is basically the same generic uniwheel trailer except with the springs on the rear stays and a slightly less beefy QR. The weld quality may differ and certainly the Q/R for attachment to the bike.
    You would probably not like to put 88lbs in it, plus the 18lbs of trailer that's a lot on a one wheel trailer. It is good for lighter loads though. I use mine for a fishing seatbox as it is just the right size, and for my camping stuff but it's easy to get over the _comfortable_ weight and then it is harder to park or to walk with the bike. I think anything over 55lbs and it's probably best to use two wheels.

    Are y'all using this on a motorbike? I have to say that's a lot of extra stress on something like that
    Seems even more than that of putting a motor on a bicycle lol

    It puts a twisting force on the frame from the connection at the axle, but only when parking and using the bike to stop the trailer falling over.. Keeping it at the right angle to begin with means there is not too much force trying to twist the frame. Obviously while riding at a decent pace there is no twisting it just balances. The weight goes on the rear wheel and the trailer wheel, but the weight in the trailer is closer to its own wheel so the bike wheel isn't taking all that much. Hasn't been a problem anyway even with a 32 spoke 700c wheel.
    A two wheel trailer, as well as being easy to park because it won't tip over, has the cargo more over its axles so it barely adds to rear wheel load at all. I would love to have both kinds but I would love ten bikes too.
    The motor's not even on my bike yet. Bike number 8.5 is on the way though. :)

    Off topic. I have already started a thread in pictures and builds.

    Looks like an accident
    Waiting to happen

    Behind a bicycle going too fast down hill to pedal, it can push a bit because it's in the slipstream. Bit of rear brake and it's fine. The BoB geometry isn't as good then. With an engine this trailer should stay straight at any speed just because you're pulling it faster than it wants to roll.
    The trailer never tips over unless you try to park it incorrectly.

    This thread from a UK cycle forum contains about as much usable info as it's possible to ever need. It should help you recognise whether the trailer you are considering has the better or worse quick release and how to go about fixing it up so it is fully suitable for long distance touring use.
