Get ready for an electrifying upgrade with the addition of a secondary battery to your Super 73 ZG! In this video, we'll guide you step by step on how to install a new 15-amp hour battery to the original 8.6-amp hour battery, both at 36 volts. While it's important to note that this will void your original manufacturer warranty, the added power and increased range will make it all worth it!

We'll start by removing screws and freeing the saddle, followed by mounting the battery and cutting away any cable ties that might be holding the cables. After that, we'll unscrew the top of the saddle to reveal the battery and controller inside. Plug in the cables and connect the batteries using a Y-connector to triple the range of your bike.

This is not just any ordinary upgrade, it's a thrilling journey to supercharge your ride! With our guidance and a few tools, you'll have your Super 73 ZG ready for a wild adventure. So buckle up and let's get started!
