I like the look of single wheel trailers which keep your cycling foot print low, but I don't like how they all seem to mount directly to your rear wheel axle. Does anyone make a single wheel trailer with a double wheel (BOB) type hitch, where the trailer could be easily detached or in a worse case scenario won't cause you to jack knife? Also, I've read about stability issues with single wheel trailers and the whole wavering thing when going downhill, but would this be solved by having two wheels back there? This is where the idea bit comes in, but I was thinking, how about a long, narrow single wheel type trailer with both a ball type hitch like on the larger BOB type trailers, but instead of having a single wheel at the back it has two wheels so it would be more stable and narrower than a BOB? I'm mainly thinking of all of this because at some point my wife and I would like to do some cycle touring and I'd like to have the ability to bring along a PakBoats PakCanoe which weighs about 50#. I'm not sure what the stowed dimensions of the boat are but I'm sure it's probably more oblong, since most folding kayaks and canoes tend to pack up into similar dimensions. I'm just thinking if the PakCanoe folds down to say 40" or so it might be too long to fit into a BOB trailer and so might be more suited to a longer single wheel trailer design, but then there's the whole attachment and stability issues. I'm all for making my own trailer too, in fact that'd be my preferred method rather than buying something and having to modify it or make it work for my needs. Suggestions, advice?
