It might just be a matter of getting used to it. I've been using handlebars for the last few years and now anytime I ride hands-free (eating a snack, getting something out of my backpack etc) it feels very unstable. In fact, when riding fast I'm not game to let go of the bars because I find the speed wobbles (both longitudinal and lateral) very unsettling.

Also, the surface contact of the single M10x30 button head bolt is crappy. You should try to find a washer with a small OD(17mm or less).
Maybe yours is defective. I have over 3000km on my Shadow base/bar and it's never come loose once. When I first set it up I cranked it down pretty tight and used threadlocker on the bolt.

So you can get the feel and ride "cautiously", I believe using these bars and riding fast is for advanced/expert level. I thought I was pretty rock solid riding on grass and large gravel, and I can ride with just pedal pressure for balance(no arms needed). There is very little reporting by riders using this on anything less than a 36".
Again, I think it's just a matter of getting used to it. Same with the larger wheel sizes - compared to smaller wheels I would describe a 36" as harder to mount but easier to ride.
