How Much Horsepower Does a Sur-Ron Have? Full Model Breakdown
Share
Sur-Ron lists power in kilowatts, not horsepower, which leaves many buyers guessing. Converting those numbers gives a clearer sense of how each model performs against gas bikes.
Here is the horsepower of every current Sur-Ron, plus what those figures actually mean on the trail.
Why Sur-Ron Power Is Listed in Watts
Electric motors are rated in watts and kilowatts (kW), while gas engines are rated in horsepower. To compare them, you convert.
The math is simple: 1 kW equals about 1.34 horsepower. So a 6 kW motor produces roughly 8 hp, and a 22.5 kW motor produces roughly 30 hp. Keep in mind that electric motors deliver peak torque instantly, so a Sur-Ron often feels quicker than its horsepower number suggests. For the raw power figures, see our guide on how many watts a Sur-Ron has.
Sur-Ron Horsepower by Model
This chart breaks down peak power, horsepower equivalent, and top speed across the Sur-Ron lineup:
| Model | Peak Power | Horsepower (approx.) | Top Speed |
|---|---|---|---|
| Hyper Bee (youth) | 5,000W (5 kW) | ~6.7 hp | 40 mph |
| Light Bee X (standard) | 6,000W (6 kW) | ~8 hp | 46 mph |
| Light Bee X (2025+) | 8,000W (8 kW) | ~10.7 hp | 46 mph |
| Ultra Bee (standard) | 12,500W (12.5 kW) | ~16.8 hp | ~55 mph |
| Ultra Bee HP (2025/26) | 21,000-24,500W | ~28-33 hp | 59 mph |
| Storm Bee | 22,500W (22.5 kW) | ~30 hp | 68 mph |
Sur-Ron Light Bee X Horsepower
The Light Bee X is the model most riders mean when they ask about Sur-Ron horsepower. It remains the best seller thanks to its light weight and balanced power.
Standard Light Bee X models make 6 kW peak, which is about 8 hp. The upgraded 2025 version jumps to 8 kW, or roughly 10.7 hp, and the latest builds push toward 10 kW. Despite the modest horsepower figure, the bike weighs only about 110 pounds, giving it a power-to-weight ratio that embarrasses many heavier 125cc gas bikes off the line.
Sur-Ron Ultra Bee Horsepower
The Ultra Bee sits in the middle of the range but has become Sur-Ron's performance star. The original delivered 12.5 kW, or about 16.8 hp.
The newer Ultra Bee HP raises peak output to 21 kW and up to 24.5 kW on the 2026 model, which is roughly 28 to 33 hp. That power, paired with around 383 lb-ft of max wheel torque, rivals gas-powered 250cc dirt bikes in acceleration while staying far lighter.
Sur-Ron Storm Bee Horsepower
The Storm Bee is the most powerful production Sur-Ron. Its water-cooled motor produces 22.5 kW peak, which converts to about 30 hp, and it tops out near 68 mph.
Liquid cooling lets the Storm Bee hold that output during long, aggressive sessions without the power fade common on air-cooled bikes. For how these numbers translate to real-world speed, check our Sur-Ron speed test.
How Sur-Ron Horsepower Compares to Gas Bikes
Horsepower alone undersells an electric bike. Torque delivery and weight matter just as much. Here is how a Light Bee X stacks up against a typical small gas dirt bike:
| Measurement | Sur-Ron Light Bee X | Gas 125cc Dirt Bike |
|---|---|---|
| Peak horsepower | ~8-11 hp | ~9-12 hp |
| Peak torque | Instant, from 0 rpm | Builds with revs |
| Curb weight | ~110 lbs | ~190-220 lbs |
| Maintenance | Minimal, no oil or clutch | Regular oil and chain service |
The lighter Sur-Ron with instant torque often accelerates harder at low speed than a gas bike with similar horsepower. If you are weighing your options, our Sur-Ron alternatives guide compares competing brands.
Common Mistakes When Comparing Horsepower
- Comparing peak power to a gas bike's rated power without accounting for weight
- Confusing continuous power with peak power, which can be half the figure
- Assuming higher horsepower always means a faster bike, when gearing and weight also matter
- Ignoring torque, where electric motors hold a clear advantage off the line
- Expecting full power when the battery is low or the motor is hot
Frequently Asked Questions
How much horsepower does a Sur-Ron Light Bee X have?
About 8 hp on standard 6 kW models and roughly 10.7 hp on the 2025 and newer 8 kW version.
What is the most powerful Sur-Ron?
The Storm Bee, at 22.5 kW peak, which is approximately 30 horsepower. The newest Ultra Bee HP comes close at 24.5 kW.
How do you convert Sur-Ron watts to horsepower?
Multiply kilowatts by 1.34. For example, 8 kW times 1.34 equals about 10.7 hp.
Is a Sur-Ron faster than a 125cc dirt bike?
Often yes at low speed, because the Sur-Ron is lighter and delivers instant torque, even when horsepower figures are similar.
Why does my Sur-Ron feel less powerful sometimes?
A low battery, a hot motor, or Eco mode all reduce available output. Full power returns on a charged battery in Sport mode.
Specifications vary by model year and region, and horsepower figures are converted approximations. Always confirm current specs with Sur-Ron or an authorized dealer before buying.
