Aluminium clamps brackets for bicycle frame tubes to hold ebike battery pack / mid frame storage box

Made custom clamps to hold the mid frame battery or storage box in place for two Schwinn Point Beach cruiser bikes. Used basic tools. First attempt at this; had fun and got a new skill. Used metal pipes with diameters as close as possible to the frame tubes for bending the flat bar. Drilled the holes larger than the diameter of the mounting bolts, or make oval holes, because the rubber protectors inside the clamps tend to spread them apart.
