When it comes to pushing the limits of electric moto performance, few upgrades make as dramatic an impact as upgrading your power controller. Whether you're riding a Talaria Sting, Surron Ultra Bee, or a modded e-moto build, the right controller can completely transform your machine—giving you more torque, higher top speed, and greater responsiveness.
At TBElectricMoto, we help riders get the most out of their rides by offering a wide range of high-performance power controllers and e-moto parts. In this guide, we’ll break down what power controllers do, how they unlock performance, and which ones are best for popular bikes like the Talaria Sting and Surron Ultra Bee.
What is a Power Controller in an E-Moto?
A power controller, sometimes referred to as a motor controller, acts as the brain of your e-moto’s drivetrain. It regulates how much electrical current from your battery goes to the motor, which in turn dictates how much torque and speed your bike can generate.
Controllers manage acceleration curves, regen braking, throttle response, and peak power output—making them critical for riders who want full control over their ride experience.
Why Upgrade Your E-Moto Power Controller?
Stock controllers are designed for mass-market reliability, not peak performance. Upgrading to a programmable or performance-oriented controller allows you to:
-
Boost torque output, especially off the line
-
Increase top speed limits
-
Customize throttle response
-
Enhance battery efficiency or thermal performance
-
Integrate with higher-capacity batteries and aftermarket motors
These benefits make power controllers essential for performance builds and race setups.
Popular E-Moto Power Controllers and Best Use Cases
Talaria Sting Power Controllers
The Talaria Sting is a high-performing platform that really wakes up with a controller upgrade. Riders often turn to aftermarket controllers like those from EBMX or Votol for improved responsiveness and torque.

Surron Ultra Bee Motor Controllers
The Surron Ultra Bee is known for its agility and trail-readiness, but it shines brightest with a controller like the Torp TC500 or EBMX X-9000. These options provide advanced programmability and smoother throttle mapping.

E-Ride Pro, Talaria XXX, and Custom Builds
Power mods are particularly useful for tuning bikes like the E-Ride Pro SS, Talaria XXX, or even DIY builds. These platforms benefit significantly from tuning-focused controllers that pair with high-discharge batteries and enhanced cooling.

Torque vs Speed: Tuning Trade-Offs
Unlocking more torque often means sacrificing a bit of top-end speed, and vice versa. The key is balancing motor characteristics, gearing, and controller parameters to suit your ride style.
For trail riding or steep climbs, torque-focused tuning is ideal. For track use or road cruising, a higher top-speed configuration may be preferable. Advanced controllers let you switch profiles depending on terrain, which is a major benefit of performance tuning.
Pairing Controllers with Batteries and Motors
Upgrading your controller without considering your battery’s discharge rate or your motor’s thermal capacity can lead to overheating or power cutoffs. For a reliable system, consider:
-
High-performance batteries: Battery Options
-
Motor upgrades: Motors Collection
-
Matching wiring harnesses and cooling systems
When matched correctly, these components create a high-output, thermally efficient system.
Gearing and Sprockets: Optimizing Power Delivery
Pairing your controller upgrade with proper gearing can further optimize your powerband. For torque-heavy setups, consider smaller front sprockets or larger rear sprockets. For speed-focused builds, do the reverse.
Check out the Sprockets and Chains Collection to dial in your setup.
Other Upgrades to Maximize Controller Gains
To truly harness the performance of a new controller, consider upgrading other areas like:
-
Suspension for better traction: Suspension Collection
-
Brakes for higher stopping power: Brakes Collection
-
Cockpit controls for tunable throttle response: Cockpit Collection
These work in harmony with your controller to create a more responsive and controlled ride.
