Nucular P24F Upgrade Kits: Sur-Ron, Talaria, Apollo RFN, Arctic Leopard, E Ride Pro SS & More
Nucular P24F:
One Controller,
Every Bike
Whether you're on a Sur-Ron, Talaria, Apollo RFN, Arctic Leopard, E Ride Pro SS, or building something completely custom — the Nucular P24F is the controller upgrade that changes what your bike is actually capable of. And HPC has a plug-and-ride kit configured specifically for your machine.
We've tested just about every controller on the market. After years of running Nucular hardware in-house and on HPC builds, the verdict hasn't changed: these are the best e-bike controllers available. Not best-in-class for the price. Best, period.
As one of the only authorized Nucular dealers in the USA, we stock most kits domestically — no customs, no six-week shipping waits, and real after-sales support from a team that actually rides this hardware.
Why Your Stock Controller Is Holding You Back
Stock controllers on light electric motos are engineered for safety margins, warranty coverage, and legal compliance — not peak performance. The P24F removes those artificial limits. Here's what changes:
-
⚡
Massive Power Gains20–30% more output on stock battery. On 72V, gains can reach 300%. The P24F's 500A max phase current unlocks what your motor was always capable of.
-
〰
Smoother, Linear TorqueField-Oriented Control (FOC) produces clean, predictable torque delivery across the full RPM range. No choppy low-speed feel. No sudden surge at the top end.
-
⚙
Deep Tuning ControlEco/Sport modes, throttle curves, field weakening thresholds, regen braking intensity — all fully adjustable via the on-board computer or Bluetooth app.
-
🔋
Better Range & Battery HealthIntegrated BMS logic monitors power flow in real time. More miles per charge, less heat buildup, longer pack lifespan — especially important on performance builds.

Regenerative BrakingTunable from subtle engine braking to aggressive deceleration. Recovers energy on descents and genuinely transforms the feel of technical trail riding.

Plug-and-Ride Kits — Find Your Bike
Every kit below is pre-configured with the correct firmware, wiring harness, and mounting hardware for that specific platform. Plug in, tune up, ride out — no custom fabrication, no bare-controller wiring projects.
/ Segway X260 Sur-Ron
Integrates directly with stock throttle, kickstand, fall sensor, and key — feels completely factory. On stock battery: ~2,000W additional output (20–30% gain). On 72V: power exceeds 20kW. Field weakening means higher top speeds alongside the torque increase, not just one or the other.
View Sur-Ron Kit →MX3 / MX4 / MX5 Talaria
Stock 60V: up to 30% more power. On 72V battery (MX3/MX4): up to 300% gain over stock. Model breakdown: MX3 → up to 8kW · MX4 Greenway 60V → up to 12kW · MX5 Greenway 72V → up to 15.2kW. Plug-and-play — zero cutting, zero splicing.
View Talaria MX Kit →For riders who want to find out what the XXX platform is actually capable of. On 72V: up to 300% more power than stock. FOC keeps delivery composed even at extreme outputs — but make no mistake, this transforms the XXX into a fundamentally different machine.
View Talaria XXX Kit →Fits the Apollo RFN RS Road (L1E), RS Endurance (L1E), and Rally Pro. Up to 12kW on stock battery. Connects directly to standard RFN wiring instead of the factory controller. Road versions retain full headlight, brake light, and turn signal function. Stock front guard keeps the OEM look.
View Apollo RFN Kit →The Arctic Leopard's 72V lithium platform and powerful direct-drive motors are a natural match for the P24F's performance envelope. The Nucular kit brings full FOC tuning, adjustable regen braking, and field weakening to one of the more capable off-road e-moto platforms on the market right now.
View Arctic Leopard Kit →Plug-and-ride kit connecting directly to stock wiring in place of the factory controller. Includes the P24F with E Ride Pro SS-specific firmware, on-board computer with fork stem mount, CAN-wire, and all necessary connectors plus a plastic mounting adapter. No drilling, no fabrication.
View E Ride Pro SS Kit →Not on this list? There's a kit for that too.
The Universal P24F Kit — Any E-Bike
Running a platform we haven't pre-configured? Building a custom machine? The standard Nucular P24F controller is available without a bike-specific harness — compatible with any brushless hub motor or direct-drive setup running in the 48–78V window. This is what serious builders reach for when they want the absolute best controller on the market in a custom application.
Same 27kW peak power. Same full FOC algorithm. Same deep tuning capability. You bring the bike — the P24F handles the rest.

The P24F is the foundation. These are the components that let you tune, monitor, and control your setup exactly how you want it.
On-Board Computer 2.0
Handlebar-mounted display and primary programming interface. Live ride data — speed, battery, mode. Every P24F parameter is accessible here. Latest firmware update makes it more intuitive than ever.
Bluetooth Module
CAN-bus wireless module for configuration via Android or iOS app. Cleaner cockpit builds, field tuning without tools. Many builders run both.
Universal Thumb Throttle / Regen Lever
Purpose-built for Nucular controllers. Plug-and-play, no adapters needed. Use as a primary throttle on custom builds or as a dedicated regen lever for precise engine braking control.

Frequently Asked Questions
HPC carries pre-configured P24F kits for the Sur-Ron Light Bee / Segway X260, Talaria Sting MX3/MX4/MX5, Talaria XXX, Apollo RFN (RS Road, RS Endurance, and Rally Pro), Arctic Leopard, and E Ride Pro SS. For any other platform, the standard universal P24F kit is available for custom and DIY builds on any compatible 48–78V brushless motor system.
No. Every P24F kit is fully compatible with your stock battery and delivers real, immediate performance improvements. The controller's full potential is unlocked on a 72V pack — power gains become dramatically larger — but you can start on stock voltage and upgrade the battery separately down the line.
Plug-and-ride kits include the P24F controller pre-flashed with firmware for your specific bike, an on-board computer with mounting hardware, a CAN-bus wire, and a custom wiring harness with the exact connectors for your platform. The universal P24F kit includes the controller and core components without a bike-specific harness — designed for custom builds where you'll wire it yourself or with HPC's guidance.
The On-Board Computer 2.0 is a handlebar-mounted unit that functions as both a live display (speed, battery level, mode) and your full controller programming interface. The Bluetooth Module connects via CAN-bus and enables wireless configuration through a smartphone app, which is better for minimal cockpit builds or field tuning without tools. Many riders use both.
