Nucular P24F Controller Upgrade for the Apollo RFN

The Apollo RFN is a capable machine off the showroom floor — but it's holding back power you paid for. The Nucular P24F controller upgrade unlocks up to 27kW of programmable output and puts the tuning in your hands. Here's what an Apollo RFN controller upgrade actually changes.

What the stock controller costs you

Like most factory setups, the RFN's stock controller runs conservative current limits and a fixed power map. The Nucular P24F removes that restriction, so the motor can finally deliver its full potential — tuned to your battery and how you ride.

What you gain with the P24F

• Up to 27kW peak power — stronger acceleration and climbing.
• Intelligent FOC — smooth, efficient, quiet delivery with a natural throttle feel.
• Regenerative braking — recapture energy and add controlled engine-braking on descents.
• Full tunability — set current limits, ride modes, and throttle response yourself.

Fitment

This kit is configured for the Apollo RFN. Because it unlocks significant power, pair it with a battery rated for high current and have installation and tuning handled by an experienced technician using Nucular's software.

Complete the build

Add the Nucular On-Board Computer 2.0 for live telemetry and on-the-fly tuning, and the Nucular thumb throttle and regen lever to take full advantage of regen.
