27kW Nucular P24F Controller Upgrade for the Sur-Ron Light Bee

The Nucular P24F controller is the single most popular upgrade our Sur-Ron Light Bee and Segway X260 riders reach for — and it's easy to see why. It replaces your stock controller with a fully programmable powerhouse rated up to 27kW of peak output, unlocking performance the factory hardware simply can't touch. If you're serious about a Sur-Ron controller upgrade, this is the one.

Why upgrade the Sur-Ron Light Bee controller?

The stock Light Bee controller is deliberately conservative — it caps current, limits top speed, and gives you almost no control over how power is delivered. That's fine out of the box, but it leaves a huge amount of the motor's capability on the table. The Nucular P24F removes that ceiling and hands the tuning back to you.

What the Nucular P24F delivers

• Up to 27kW peak power — far beyond stock, for hard acceleration and steep climbs.
• Intelligent FOC (field-oriented control) — smooth, efficient, quiet power delivery instead of harsh on/off feel.
• Regenerative braking — recover energy and add controlled engine-braking feel on descents.
• Deep tunability — dial in current limits, throttle response, speed, and ride modes to match your battery and riding style.
• Rugged, high-current build — engineered for the demands of a high-power light e-moto.

Works on the Segway X260 too

The X260 shares the Light Bee platform, so this same upgrade applies. Whichever you ride, you get the same jump in power, control, and rideability.

Building around it

To get the most from the P24F, pair it with a battery capable of high continuous and peak current — 27kW asks a lot of your pack. We also strongly recommend the Nucular On-Board Computer 2.0 so you can see live telemetry and tune on the fly, plus the Nucular thumb throttle and regen lever to make full use of regen.

Install notes

This is a serious performance upgrade, and correct configuration matters. The controller is set up through Nucular's software, and we recommend installation and tuning by an experienced e-bike technician — done right, the difference is night and day.
