This is the controller you’ve been searching for. Built with the highest quality and offered at the lowest price on the internet, this controller finally gives riders a real alternative to the overpriced BAC855. No more stressing about cost now you can run the same power for only $350.

This controller includes a direct-fit connector for your battery and motor, designed to plug straight into your bike with zero hassle. The entire kit is 100% plug and play, no soldering, no sketchy wiring, no guesswork. We’ve already done everything on our end to make sure it pairs perfectly with Super 73’s.

The controller is rated 48V 45A (60A peak), giving you enough output to comfortably run 4 kW. With this upgrade, a stock ZX jumps from 28 → 37 mph, —with torque that nearly doubles on both bikes.

 This kit includes 

• Display 

• Controller

• Extended battery leads 

• Battery holder 

This kit also pairs perfectly with our SurRon throttle for even smoother control. And key ignition 

Please Note: Controllers and connectors are custom-built and soldered to order. Expect 4–5 weeks for shipping.
