I have an antique bike I ride in the local Veterans Day parade. It's painted Navy shore patrol black and white, sports a blackout light up front, and has three 50 cal ammo cans mounted. Two mounted on the sides of the rear rack and one mounted to the handlebar. 2.125 white wall tires round it out. I always put on my cracker jacks (Navy Uniform) with leggings on as well as a steel WWII era helmet. I look like an SP patrolling the strip down town keeping the drunk Sailors on liberty out of trouble. Everyone complements me as I slowly pedal by.
The 50 cal ammo cans round out the military look. The only problem with them is weight! They simply weight too much for a daily rider as there made of steel. Aluminum boxes might work until you accidentally drop the bike on one and bend it. Fabric or hard plastic panniers would take the hit with nary a care or damage.
