The Surron Ultra Bee top speed is just over 90 km/h for the standard bike and about 95 km/h for the Ultra Bee HP. Those are the headline numbers, but they don’t tell you how fast the bike feels, how long it holds that pace, or how it compares with the Light Bee X and Storm Bee.
In this guide we explain the Surron Ultra Bee top speed in real-world terms, convert kilowatts into horsepower, list the full specs, and cover battery range, seat height and street-legal rules. Figures are current as of October 2026. If you’re new to the bike, our complete Surron Ultra Bee guide is a good place to start.
Surron Ultra Bee top speed at a glance
| Model | Peak power | Claimed top speed |
|---|---|---|
| Ultra Bee R / T (standard) | 12.5 kW | 90+ km/h (about 56 mph) |
| Ultra Bee X HP (MY25, off-road) | 21 kW | 95 km/h (about 59 mph) |
| Ultra Bee HP R / T (MY26) | 24.5 kW | 95 km/h (about 59 mph) |
| Surron Light Bee X (MY26) | 10 kW | 80 km/h |
| Surron Storm Bee | 22.5 kW | 110 km/h |
Notice that the HP’s extra power barely changes the Surron Ultra Bee top speed. Surron uses the extra output for acceleration and hill climbing, while top speed stays electronically limited to around 95 km/h. That’s a sensible call for a trail bike on knobby tyres.
How fast does a Surron Ultra Bee go in the real world?
Independent testing puts the Surron Ultra Bee top speed close to Surron’s claims. VORO Motors’ claimed-vs-tested breakdown reports riders reaching the mid-to-high 50s in mph, roughly 90–95 km/h, on flat ground in the highest power mode.
On the day, how fast a Surron Ultra Bee goes depends on several things:
- Riding mode. Lower modes cap speed and power, so you only see the full Surron Ultra Bee top speed in Sport or Turbo.
- Battery charge. Top-end pull usually softens as the battery runs down, so the bike feels fastest on a full charge.
- Rider weight and position. A heavier rider sitting upright will lose a few km/h compared with a lighter rider tucked in.
- Gearing. A bigger rear sprocket improves acceleration but lowers top speed. A smaller one does the opposite.
- Tyres and pressures. The T’s knobby tyres add more rolling resistance than the R’s dual-sport tyres.
- Wind and gradient. Headwinds and uphill sections cut speed quickly.
Acceleration matters more than top speed
On a trail you rarely sit at the Surron Ultra Bee top speed for long. What you notice is how quickly the bike gets there. Surron quotes 0–50 km/h in 1.84 seconds and 0–80 km/h in 3.7 seconds for the 2026 HP, which feels very quick off the line, especially on dirt.
The standard bike is gentler, which is exactly why many newer adult riders prefer it. You can always add power later, but it’s hard to learn on a bike that frightens you.
Surron Ultra Bee hp: power and torque explained
Surron quotes power in kilowatts, but most riders still think in horsepower. One kilowatt is about 1.34 hp, so here is the Surron Ultra Bee hp for each version.
| Version and mode | Power (kW) | Power (hp) | Torque at the wheel |
|---|---|---|---|
| Standard Ultra Bee, rated | 6 kW | About 8 hp | – |
| Standard Ultra Bee, peak | 12.5 kW | About 16.8 hp | 440 Nm |
| Ultra Bee X HP / MY25 HP, Sport | 18 kW | About 24 hp | – |
| Ultra Bee X HP / MY25 HP, Turbo | 21 kW | About 28 hp | 511 Nm |
| Ultra Bee HP MY26, Turbo | 24.5 kW | About 33 hp | 520 Nm |
When people search for “Ultra Bee HP”, they usually mean one of two things: the horsepower figure, or the HP model name. The HP model is Surron’s high-power version, and it roughly doubles the standard bike’s peak output.
The horsepower numbers look small next to a petrol bike, but they’re misleading. Electric motors make strong torque from zero rpm, and Surron quotes torque at the rear wheel, after the final drive, not at the motor shaft. That’s why an Ultra Bee with 16.8 hp pulls harder out of a corner than the number suggests.
The HP’s Turbo mode delivers peak output in short bursts of about ten seconds. In its 2025 Ultra Bee HP review, Cycle News found the Turbo boost hard to manage on the trail and felt Sport mode was plenty for most riding.

The Surron Ultra Bee top speed, power and range figures here come from Surron Australia and Australian dealer listings. You can check the standard bike’s numbers on the official Surron Australia Ultra Bee page.
Surron Ultra Bee battery and range
The Surron Ultra Bee range comes from a removable 74V lithium battery: 55Ah (4,070 Wh) on the standard bike and 60Ah on the HP. The pack weighs around 20 kg and can be charged on or off the bike.
Claimed range figures are measured at a steady speed on flat ground:
- Standard Ultra Bee: up to 140 km at 40 km/h, or 90 km on the WMTC test cycle
- Ultra Bee HP: up to 115 km at 50 km/h
Real riding is different. Cycle News got more than 2.5 hours of riding and close to 100 km from the 2025 HP. Steep climbs, sand, mud, a heavier rider and Turbo mode all bring range down, and so does holding the Surron Ultra Bee top speed for long stretches. Gentle fire-road cruising pushes range up.
Charging time
With the standard fast charger, the Ultra Bee takes around four hours for a full charge, and the HP’s charger takes about 2.5 hours to go from 20% to 80%. If the bike will sit for a while, store it between about 20% and 80% rather than full or flat.
Battery care also protects performance. A healthy pack holds its voltage under load, so a well-kept bike holds its full Surron Ultra Bee top speed for longer into each ride. Spare chargers and replacement parts are in our Batteries and Chargers range.
Ultra Bee seat height and size
The Ultra Bee seat height is 910 mm, with around 318 mm of ground clearance. That’s tall for a mid-size bike, and it’s the spec shorter riders should check first.
- Riders around 175 cm and taller usually fit the bike comfortably.
- Riders between about 165 cm and 175 cm can manage with some experience, especially once the suspension sags under their weight.
- Shorter riders often prefer the Light Bee X, which sits around 830 mm.
Suspension set up for your weight makes a big difference to how tall the bike feels. Our upgraded Ultra Bee rear shock springs help match the bike to heavier riders. Talk to us before changing suspension on a registered bike.
Surron Ultra Bee top speed: 2025 vs 2026 models
Surron has updated the Ultra Bee HP every year, so it’s worth knowing which model you’re looking at, especially on the used market.
| Model year | Peak power | Torque at the wheel | Top speed | Key changes |
|---|---|---|---|---|
| 2023–2024 standard Ultra Bee | 12.5 kW | 440 Nm | 90+ km/h | Original 74V 55Ah platform |
| 2025 Ultra Bee HP / X HP | 21 kW | 511 Nm | 95 km/h | 60Ah battery, Turbo mode, more riding modes |
| 2026 Ultra Bee HP R / T | 24.5 kW | 520 Nm | 95 km/h | Wheelie control, app connectivity, over-the-air updates |
The Surron Ultra Bee top speed has stayed at about 95 km/h since the HP arrived, but each update has added acceleration and control. If you’re comparing a 2025 bike with a 2026 bike, you’re mainly paying for the extra punch out of corners and the new electronics, not a higher top speed.
Does the Surron Ultra Bee top speed drop as the battery drains?
A little, yes. Lithium batteries deliver slightly lower voltage as they discharge, and the motor’s top-end speed depends on that voltage. Most riders notice the bike feels sharpest above about half charge, and a fraction softer near the end of a ride.
It’s normal and it isn’t a fault. If the Surron Ultra Bee top speed falls well short of 90 km/h on a full charge, though, something else is going on. The usual causes are a low-power riding mode, a tired or unbalanced battery, a dragging brake or very low tyre pressures.
6 tips to keep your Ultra Bee at full top speed
- Charge properly. Start important rides with a full, balanced battery, and store the bike at around 20–80% between rides.
- Check tyre pressures. Soft tyres feel grippy off-road but cost you speed on hard surfaces.
- Keep the chain or belt adjusted. A tight or dry chain wastes power before it ever reaches the wheel.
- Make sure the brakes aren’t dragging. A sticking caliper quietly cuts your Surron Ultra Bee top speed and your range. Our Surron Ultra Bee brakes guide shows how to check.
- Pick the right mode. Use Sport for open sections and save Turbo for short bursts.
- Keep the bike clean and dry. Mud adds weight, and water in connectors can cause cut-outs at speed.
Look after these basics and your bike will keep hitting its full Surron Ultra Bee top speed for years, not just in its first few months.
Is the Surron Ultra Bee street legal?
Yes, if you buy the right version and register it. The Ultra Bee R and T, including the HP R and T, are ADR approved and can be registered as motorcycles in Australia. The Ultra Bee X HP is off-road only and can’t be registered. Once registered, you’ll need a motorcycle licence or learner permit, CTP insurance and an approved helmet.
A registered bike must stick to the speed limit like any other motorcycle. The Surron Ultra Bee top speed of about 95 km/h is fine for 80 km/h rural roads, but it isn’t suited to freeways signed at 100–110 km/h.
Our Surron Ultra Bee price guide explains registration costs, and the Queensland StreetSmarts e-motorbike rules show how strictly unregistered riding is now policed.
Surron Light Bee vs Ultra Bee
| Spec | Light Bee X (MY26) | Ultra Bee (standard) |
|---|---|---|
| Peak power | 10 kW | 12.5 kW |
| Torque at the wheel | 295 Nm | 440 Nm |
| Top speed | 80 km/h | 90+ km/h |
| Battery | 72V 35Ah (about 2.5 kWh) | 74V 55Ah (4,070 Wh) |
| Claimed range | Up to 75 km at 40 km/h | Up to 140 km at 40 km/h |
| Weight | 59 kg | 88–93 kg |
| Seat height | About 830 mm | 910 mm |
| Road legal in Australia | No | Yes (R and T) |
The Light Bee X is the more playful bike. It’s around 30 kg lighter, easier to throw around tight singletrack and easier to lift onto a trailer. The Ultra Bee is more stable at speed, more comfortable for taller riders, goes much further on a charge and can be registered.
Choose the Light Bee if you’re under about 170 cm, a newer rider, or mostly ride tight trails. Choose the Ultra Bee if you want the higher Surron Ultra Bee top speed, longer range or road registration. Our Surron Light Bee X review has the full picture.
Storm Bee vs Ultra Bee
| Spec | Ultra Bee HP (MY26) | Storm Bee |
|---|---|---|
| Peak power | 24.5 kW | 22.5 kW |
| Torque at the wheel | 520 Nm | 520 Nm |
| Top speed | 95 km/h | 110 km/h |
| Battery | 74V 60Ah | 90V 48Ah (4,320 Wh) |
| Weight | About 88.5–93 kg | About 118 kg |
| Seat height | 910 mm | 940 mm |
| Wheels | 19/18-inch | 21/18-inch |
| Suspension travel | 240 mm | 290 mm |
| Typical price | From about $10,490 + ORC | About $12,990 |
The Storm Bee is Surron’s full-size enduro-style bike. It beats the Surron Ultra Bee top speed by about 15 km/h and has longer suspension travel and a motocross-size 21-inch front wheel. It’s also about 25–30 kg heavier and a few thousand dollars dearer.
For most riders the Ultra Bee HP is the better buy. It matches the Storm Bee’s torque, is slightly quicker to 80 km/h thanks to its lighter weight, and is far easier to manage on tight trails. Choose the Storm Bee only if you’re an experienced rider who spends a lot of time on fast, open ground.
How to get more speed from your Ultra Bee
If the stock Surron Ultra Bee top speed isn’t enough, there are proven ways to add performance. All of them are for off-road use on private land or tracks.
- Gearing. A smaller rear sprocket lifts top speed at the expense of acceleration. Our Ultra Bee modifications include sprockets and chains.
- Controller upgrade. The EBMX X-9000 controller unlocks far more power. Browse our EBMX Ultra Bee mods.
- Motor upgrade. The EBMX XUB-80 Ultra Bee motor handles the extra current from an upgraded controller.
- A turn-key race build. Our Stage 3 Surron Ultra Bee runs a 50 kW race tune.
Power upgrades take a registered bike out of compliance and can affect your warranty, so ask us before modifying a road-registered Ultra Bee.
