TC Bros. manufactures heavy duty battery boxes that are designed to stand up to the vibration and abuse that a hardtail chopper provides. These sturdy, made in USA boxes are a great time saver and alternative to fabricating one yourself in your garage. For metric builds, check out our unique electronics "fake oil tank". This provides a good place to hide all of your wiring and electronic components, while filling that empty space under your seat on a hardtail frame.
