The Surron Ultra Bee X is the off-road-only version of the Ultra Bee HP. It packs up to 21 kW, 511 Nm at the rear wheel and a 95 km/h top speed into an 88.5 kg chassis, but it has no ADR compliance, so it can’t be registered for the road in Australia.
That trade-off is the whole story. The Surron Ultra Bee X gives you HP performance without lights, mirrors or a number plate, for riders who only ever ride on private land, tracks and off-road parks. In this guide we cover the Ultra Bee X specs, hp, top speed and price, and compare it with the road-legal R and T so you can choose the right one. New to the model? Start with our complete Surron Ultra Bee guide.
What is the Surron Ultra Bee X?
Surron uses letters to tell you what each bike is for. On the Light Bee, “X” marks the off-road model, and the Surron Ultra Bee X follows the same idea. “HP” means high power. So the Ultra Bee X HP is the high-power Ultra Bee built purely for off-road use.
The road-registerable versions are called R and T. The R has dual-sport tyres and the T has knobby off-road tyres, but both carry ADR approval, lights, indicators and mirrors so they can be registered. The Surron Ultra Bee X drops the road equipment and the compliance, and is sold strictly for off-road riding.
The X HP arrived as a 2025 model with a bigger 60Ah battery, more riding modes and roughly 68% more peak power than the original Ultra Bee. For 2026, Surron’s headline update has been the ADR-approved Ultra Bee HP R and T, which push peak power to 24.5 kW.
Surron Ultra Bee X specs
Here are the published Surron Ultra Bee X HP specs from Australian retailer listings.
| Spec | Surron Ultra Bee X HP |
|---|---|
| Peak power | 21 kW in Turbo, 18 kW in Sport |
| Torque at the wheel | 511 Nm |
| Top speed | 95 km/h |
| Battery | 74V 60Ah lithium (about 4.4 kWh) |
| Claimed range | Up to 115 km at 50 km/h |
| Charging | About 2.5 hours from 20% to 80% |
| Kerb weight | 88.5 kg |
| Seat height | 910 mm |
| Ground clearance | 315 mm |
| Wheelbase | 1,380 mm |
| Tyres | 80/100-19 front, 100/90-18 rear (off-road) |
| Suspension travel | 240 mm front and rear |
| Maximum rider load | 100 kg |
| Road legal in Australia | No, off-road only |
The numbers that matter most are the 60Ah battery and the jump in power. Together they make the Surron Ultra Bee X far stronger on climbs than the standard bike, while the range stays close to the original.
Surron Ultra Bee X hp: how much power does it make?
Surron quotes kilowatts, so here’s the Surron Ultra Bee X hp in plain terms. One kilowatt is about 1.34 hp.
| Mode | Power (kW) | Power (hp) |
|---|---|---|
| Sport | 18 kW | About 24 hp |
| Turbo | 21 kW | About 28 hp |
| Standard Ultra Bee, for comparison | 12.5 kW | About 16.8 hp |
That’s around 68% more peak power and 16% more torque than the standard Ultra Bee. On the trail you feel it most when climbing, pulling out of turns and riding through sand, where the standard bike can start to feel stretched.
Turbo mode gives you the full 21 kW in short bursts of about ten seconds. In its 2025 Ultra Bee HP review, Cycle News found Turbo hard to manage on technical trails and preferred Sport mode for most riding. Our advice is the same: save Turbo for big climbs and open ground.
Keep in mind that electric torque arrives instantly. Even 24 hp feels very strong when 511 Nm hits the rear wheel from a standstill, so new owners should start in a low mode.
Ultra Bee X top speed and acceleration
The Ultra Bee X top speed is about 95 km/h, the same as the road-legal HP models and slightly higher than the standard Ultra Bee’s 90+ km/h. The controller limits top speed, so the extra power goes into acceleration rather than a higher maximum.
In real-world testing, riders report the HP platform getting close to its claimed top speed on flat ground in the highest power mode. Rider weight, gearing, tyre pressures and battery charge all affect what you’ll see on the day.
Acceleration is where the Surron Ultra Bee X shines. Surron quotes 0–50 km/h in under two seconds for the HP platform, which is quicker than most riders will ever need on a trail. Our Surron Ultra Bee top speed guide explains the full numbers for every version.
Ultra Bee X battery, range and charging
The Surron Ultra Bee X uses the HP’s 74V 60Ah lithium battery, which holds about 4.4 kWh. Surron rates it for up to 115 km at a steady 50 km/h on flat ground.
Off-road range is lower, and it depends heavily on how you ride. In testing of the HP platform, Cycle News got more than 2.5 hours of trail riding from a charge. Expect less if you use Turbo a lot, ride deep sand or mud, or carry extra weight, and more if you cruise fire trails in Daily or Eco mode.
Charging is flexible. Retailers list three charging levels, from about 425 W up to 1,100 W, and a 20–80% top-up takes around 2.5 hours on the fastest setting. That’s enough to recharge over lunch at a riding property with power.
A few habits protect the battery and keep the bike performing at its best:
- Let the battery cool for a while after a hard ride before charging.
- Store it at around 20–80% if the bike won’t be used for a few weeks.
- Carry a spare charger on longer trips rather than relying on one at your destination.
- Never charge a battery that’s damaged, swollen or has been submerged.
Spare chargers and battery parts for the Ultra Bee are in our Batteries and Chargers range.
Riding modes on the Surron Ultra Bee X
The X HP has more riding modes than the original Ultra Bee, which makes it easier to tune the bike to the terrain and your experience.
- Eco for gentle riding and maximum range
- Daily for relaxed trail riding
- Sport for full power without the Turbo burst
- Turbo for short, maximum-power boosts
- Crawl for very slow, controlled riding over rocks and technical terrain
- Reverse for backing out of tight spots
Crawl mode is a standout for trail riders. It lets you inch over rock steps and logs with steady, gentle drive, which is hard to do on a petrol bike without slipping the clutch.
Surron Ultra Bee X price in Australia
The Surron Ultra Bee X price in Australia is around $10,490 for the X HP, based on advertised prices from Australian retailers at the time of writing (October 2026). Prices change with stock and promotions, so check before you buy.
| Version | Road legal? | Typical price (AUD) |
|---|---|---|
| Surron Ultra Bee X HP | No | Around $10,490 |
| Ultra Bee HP R / T (MY26) | Yes | From about $10,490 + on-road costs |
| Standard Ultra Bee R / T | Yes | From about $9,990 + on-road costs |
The surprise is how close these prices are. The Surron Ultra Bee X price is roughly the same as the road-legal HP before on-road costs, so you don’t save much by going off-road only. You do save on registration and CTP every year, though, which adds up if you’ll never ride on the road. For the full breakdown, read our Surron Ultra Bee price guide.
Surron Ultra Bee X 2025 vs 2026: what’s changed?
The X HP launched as a 2025 model, and most Australian listings for it still describe that 2025 specification. The big 2026 updates arrived first on the ADR-approved Ultra Bee HP R and T.
| Feature | 2025 Ultra Bee X HP | 2026 Ultra Bee HP R / T |
|---|---|---|
| Peak power | 21 kW | 24.5 kW |
| Torque at the wheel | 511 Nm | 520 Nm |
| Wheelie control | No | Yes, IMU-based with adjustable levels |
| App connectivity | No | Yes, with over-the-air updates |
| Charging | Three charging levels | Upgraded smart charging port |
| Road legal | No | Yes |
For a pure off-road rider, the 2025 Surron Ultra Bee X is still a very strong bike. Wheelie control and app features are nice to have, but the extra 3.5 kW is the change you’d actually feel. If you’re torn, ride both before you decide.
Ultra Bee X vs Ultra Bee HP R and T
| Feature | Ultra Bee X HP | Ultra Bee HP R / T (MY26) |
|---|---|---|
| Road legal (ADR) | No | Yes |
| Lights, indicators, mirrors | No | Yes |
| Peak power | 21 kW | 24.5 kW |
| Torque at the wheel | 511 Nm | 520 Nm |
| Top speed | 95 km/h | 95 km/h |
| Battery | 74V 60Ah | 74V 60Ah |
| Extra electronics | Six riding modes including Crawl | Wheelie control, app connectivity, over-the-air updates |
| Where you can ride | Private land, tracks, off-road parks | Roads, forest roads, plus everywhere the X can go |
| Ongoing costs | No registration | Registration and CTP |
If there’s any chance you’ll want to ride on the road, or on forest roads and trails that require a registered motorcycle, buy the R or T. The 2026 HP R and T also make more power than the 2025 X HP. Choose the Surron Ultra Bee X if your riding is 100% off-road and you’d rather not pay registration every year.
Ultra Bee X vs the standard Ultra Bee
| Spec | Ultra Bee X HP | Standard Ultra Bee R / T |
|---|---|---|
| Peak power | 21 kW | 12.5 kW |
| Torque at the wheel | 511 Nm | 440 Nm |
| Top speed | 95 km/h | 90+ km/h |
| Battery | 74V 60Ah | 74V 55Ah |
| Claimed range | Up to 115 km at 50 km/h | Up to 140 km at 40 km/h |
| Weight | 88.5 kg | 88–93 kg |
| Road legal | No | Yes |
The standard bike is gentler and road legal, which makes it a better first Ultra Bee for newer riders. The Surron Ultra Bee X is the better choice for experienced riders who want maximum performance off-road.
Can you register a Surron Ultra Bee X?
No. The Surron Ultra Bee X doesn’t have ADR compliance, so it can’t be registered as a road vehicle in Australia. The Australian Design Rules set the standards every road vehicle must meet, and bolting lights and mirrors onto an X doesn’t make it compliant.
Riding an unregistered bike on public roads, footpaths or parks can bring heavy fines, and the bike can be seized. Queensland introduced tougher penalties for unregistered and unlicensed e-motorbike riders from 1 July 2026, as explained on the Queensland StreetSmarts e-motorbike page. Other states are tightening enforcement too.
Where can you ride an Ultra Bee X?
Legally, a Surron Ultra Bee X can be ridden:
- on private property with the owner’s permission
- at motocross tracks and off-road parks that allow electric bikes
- at organised events and race meetings
Rules for state forests and public off-road areas vary, and many require registration. Read our guide to electric dirt bike laws in Australia before you head out, and check with the land manager if you’re unsure.
Who should buy the Surron Ultra Bee X?
The X makes the most sense if you:
- only ride on private land, tracks or registered off-road parks
- are an experienced rider who wants HP power
- want a quiet bike for a farm or large property
- plan to race or modify the bike for performance
It’s less suited to newer riders, anyone who wants to commute or link trails on public roads, and young riders. Kids are better off on a bike sized for them, such as the Surron Hyper Bee.
Best upgrades for the Ultra Bee X
Because it never needs to pass registration, the Surron Ultra Bee X is a popular base for performance builds. These are the upgrades we fit most often.

Buying a used Surron Ultra Bee X
A second-hand Surron Ultra Bee X can be good value, but off-road bikes often live harder lives than registered ones. Check these points before you hand over money.
- Run a $2 search on the PPSR with the VIN to make sure the bike isn’t stolen or under finance.
- Ask for proof of purchase. Stolen electric bikes are common, and off-road models are a frequent target.
- Ask how the battery was stored and how many charge cycles it has done.
- Check for modifications. A tuned controller or motor isn’t a problem if it was done properly, but ask for receipts.
- Look for crash damage: bent bars and footpegs, cracked plastics, a bent rear rotor and worn suspension linkages.
- Be wary of any seller claiming an X can be registered. It can’t.
Our electric dirt bike for sale checklist goes into more detail on inspecting any used bike.
Looking after your Surron Ultra Bee X
The X needs very little maintenance compared with a petrol bike, but the extra power means wear items need more attention.
- Check brake pads and chain tension before every ride.
- Clean and lube the chain after wet or dusty rides.
- Keep the battery between about 20% and 80% for storage.
- Avoid pressure-washing the motor, controller and battery area.
- Inspect suspension linkages and footpegs after big crashes or hard landings.
