On Thursday, the handlebars came off. I was not in motion at the time so I was not hurt, but I could have been.
The Montague uses an Octagon handle bar mount. To begin the process of finding out exactly what fucking happened, I watched the installation video:
The bike came with two of the spacers mentioned in the video installed:
I measured the space above the spacers with my cheap digital caliper (seriously, spend the $10 on one of these things) and found there was only 13 mm available.
With a single spacer we now have the requisite 18mm. I used a clamp and a chunk of 2x4 to compress everything into place and torqued the bolt to spec.
I'll probably post something about this fix working (or not) down the road. I really like not having to pay to park and need the exercise to maintain my health. It'll be a shame if this bike doesn't work for me.
