I was searching the shelves in a thrift store and came across a military buttpack made to use with webbing load gear, much like a civilian “fanny pack.” I immediately saw the potential for use as a bike bag: with all the MOLLE webbing mounts on the back, it could be mounted on a rack as a pannier or looped over the handlebars.
If you read my previous posts you can review the on-going evolution of my hybridized mountain bike. I decided that I want just one bike for local errands and recreation. I live in Seattle and the region has many rail trails and local governments that promote cycling. So my bike needs to handle city streets and the obstacles as well as asphalt and gravel trails. Comfort, maneuverability, and load-carrying take precedent over speed.
