KT Sine-Wave Controller
The tuner's favorite. KT controllers pair with KT displays for deep parameter control and famously smooth, quiet sine-wave power delivery.
KT (Kunteng) controllers are a staple of the DIY scene because, paired with a KT-LCD display, they expose dozens of adjustable parameters — PAS levels, current limits, speed limits, throttle behavior — right from the display. The sine-wave drive is smooth and quiet.
They're an excellent match for generic geared and direct-drive hub motors. The key is buying the KT controller and KT display together so they communicate, and matching the controller's amperage to your motor and battery.
Where to buy
Two paths — match your spend to the build. Quality picks last longer and come with real support; affordable picks get you rolling for less. Always confirm fitment, voltage, and connectors for your bike first.

Pro tips from our test team
- Buy the KT controller and KT display as a set so the parameter menus work.
- The P and C settings unlock a lot — read a KT parameter guide before tuning.
- Great upgrade path for generic hub-motor bikes with crude stock controllers.
