I was considering a bike trailer, but my local (so-called sealed) roads have heaps of potholes and bumps.
I doubt that any trailer would stay upright, or if it did, the contents would be well shaken up or broken, even behind my electric bike with a max speed of 30kph.
Behind the MB??? No way. I'm probably just unlucky in terms of road quality, but I can barely hang onto the handlebars at 40-50kph on most of our roads, unless I stay out in the middle. The Princes Highway, (for those familiar), is relatively smooth, so when I feel lucky I use it, but I don't want to die just yet, so bumpy side-streets are the go most of the time.
If anyone can show me a trailer with good travel suspension, adjustable for load and set up for axle-level towing, I'm there.
Although not relevant, (due to lack of torque), I learned in my early days driving tractors to pull a load from as low as possible. The higher the draw-bar attaches to the towing vehicle above axle level, the more chance there is of flipping the towing vehicle. (I've done it, with my grandfather's tractor, about 35-40 years ago. He was not happy with Steve.)
