XG Controller Upgrade V1.0

Jack'D Performance Controller for JackRabbit XG Micro E-Bike 

Speed and Simplicity 

PLEASE READ FULL DESCRIPTION BEFORE PURCHASING

DOES NOT WORK ON XG PRO

Unlock the full potential of your JackRabbit XG Micro E-Bike with the Jack'D Controller Upgrade — a plug-and-play upgrade designed to increase your top speed, and give you total control over your riding experience. Whether you're looking to cruise faster or personalize your performance, this controller delivers — no fancy wiring, no soldering, no guesswork, just plug and play.

Built for the JackRabbit XG this upgrade works seamlessly with the stock battery. If you wish to run 2 Range Buster Batteries, the Range Buster Frame Mount will be required.

And here's the best part — it fits in the rear location with minimal externally visible changes. This is a full sleeper build. From the outside, it still looks mostly like a stock XG JackRabbit… until you take off. On top of that, your stock display still works along with full light functionality and the speed read out!

Please note that the controllers ship with a tune for speed, not power, acceleration, or torque. This is done to reduce the risk of damage to your bikes and you can expect similar power and acceleration performance as the stock bike. This can easily be changed by requesting a different tune, or by tuning yourself via the VESC app. Tuning is not recommended unless you are willing to accept an even higher risk of breaking components.

⚠️ Important Compatibility & Use Info

This controller is only compatible with:
✅ JackRabbit XG
❌ Not compatible with other JackRabbit models or the XG Pro. OG2, XG Pro, and MG versions are in the works, this will not work for them.

Using this controller comes with real risks:
- Even at stock power levels, this controller can damage motors if pushed too hard or used improperly, we have done our best to minimize these risks, but with the increased power, issues with the glue holding the magnets and the gears stripping are possible. This can be remedied, in most cases, by "hardening" your motor.
- Increasing power beyond the default 750W will further reduce range, increase motor heat, and increase the likelihood of damage
- Installation and use of this controller voids your JackRabbit warranty

By purchasing this controller, you acknowledge and accept full responsibility for:
- Ensuring compatibility with your bike
- Any damage to your motor, battery, controller, or other electronics
- Any personal injury or safety risks

This is a performance mod — not a toy, and not beginner-friendly. If your bike breaks or you get hurt, that’s on you.
