Coaster Brake
I would like to share this incident with everybody. After building my stretch Columbia, I broke a few rear spokes, so I trotted over (38 miles) , to the nearest bike shop and bought a new single speed rear wheel with 12 gauge spokes. Well, don't you know that I was so excited I clean forgot about the coaster brake hold down. It's not difficult to imagine what happened when I used the rear brake. Yup! I destroyed the rear wheel, and the coaster brake.
