Controller and battery dock designed specifically for the original Tower Beach Bum. This dock is fully compatible with Tower/Samsung 48V/14Ah batteries, providing a convenient and seamless charging and switching experience. With our innovative design, the battery can be effortlessly removed without disconnecting any wires, allowing for quick access to charge or switch to a fully charged battery. For added security, the battery securely locks into place using a key, and to maintain the compact design of the e-bike, it requires lifting and rotating to remove from the dock. When replacing, ensure the replacement battery dock is properly fitted to the down pipe in the frame, ensuring optimal functionality and reliability.
