I have a strong preference for practical, vintage and period-correct accessories on bicycles. However, sometimes you find new items that capture the spirit of old. I have been using a black canvas and leather Minnehaha bag on my Hercules Model G. The Model G is going up for local sale here in the Washington DC area, but I want to keep the bag.
It has that "old motorcycle" look that goes with the styling of the Columbia. After all, the American ballooners were meant to mimic the styling of classic motorcycles. It's also nice to have the durability of new leather and not have to deal with 60 year old, dried out hide.
