If you are weighing Sur-Ron Light Bee X vs Ultra Bee, the honest short answer is that rider size and terrain decide it, not the spec sheet. The Light Bee X (also sold as the LBX) is the smaller, lighter, lower bike that suits shorter riders, tight woods, and anyone still building skills. The Ultra Bee is a genuinely full-size machine with roughly double the peak power and about three inches more seat height — better for taller riders, open trails, and higher speeds, and considerably more bike to manage if you are new.
Below we lay out the published figures we could actually verify, flag where sources disagree, and give you our read as a shop that has these bikes in the building and rides them.
The short version
- Under about 5’8″, new to dirt, riding tight trails or a property: Light Bee X / LBX.
- Taller rider, mixed terrain, want to keep up with gas trail bikes: Ultra Bee.
- Experienced rider who wants a full-size electric enduro and has the space and budget: Storm Bee.
- Buying for a teenager or a first-ever dirt bike: Light Bee X, almost always.
Published specifications, side by side
Read this before the table. The figures below are taken from Sur-Ron’s UK and Canadian channels and one Australian distributor, because those are the pages that publish full specifications. A US-market bike may differ. Model year, region, and configuration all change these numbers. Treat this table as a guide to how the models relate to each other, not as the spec sheet for any particular bike. Always confirm figures against the individual listing and the unit itself before you buy.
One thing to understand before you read this table: Sur-Ron’s regional distributors publish different numbers for bikes that share a name. The Light Bee X sold in some markets is listed with a 72V/35Ah pack and 10 kW; the current Light Bee X (LBX) on Sur-Ron’s UK site is listed with a 60V/40Ah pack and 8000W. Both are official-channel figures. Which one describes a specific bike depends on model year and market, so treat the row below as two entries rather than a contradiction to resolve.
| Spec | Light Bee X (72V listing) | Light Bee X / LBX (60V listing) | Ultra Bee | Storm Bee |
|---|---|---|---|---|
| Max motor power | 10 kW | 8000W | 12.5 kW | 22.5 kW |
| Max torque (at wheel) | 217 ft-lb | 196.2 ft-lb | 324.5 ft-lb | 383.5 ft-lb |
| Battery | 72V / 35Ah Li-ion | 60V / 40Ah 21700 Li-ion, removable | 74V / 55Ah Li-ion | 104V / 55Ah Li-ion, removable |
| Curb weight | 130 lb | 125.6 lb | 187 lb | 209 / 279 lb (as published) |
| Seat height | 32.68 in | 32.6 in | 35.8 in | 37 in |
| Front fork travel | 7.87 in | 7.8 in | 9.4 in | 47 mm inverted fork (travel not published on that page) |
| Rear shock / wheel travel | 3.35 in | 3.3 / 8.3 in | 3.3 / 9.4 in | Not published on that page |
| Top speed | 50 mph | 46.6 mph | 56 mph | 68.3 mph |
| Published range | 46.60 mi @ 24.85 mph | 46.6 mi @ 24.9 mph | 62 mi @ 31 mph | 74.5 mi @ 31 mph |
| Tires | 70/100-19 front, 3.00-18 rear | 70/100-19 front, 3.00-18 rear | 80/100-19 front, 90/90-19 rear | 80/100-21 front, 100/90-18 rear |
A note on the Storm Bee rows: sources diverge here more than on any other model. Sur-Ron’s UK site publishes 22.5 kW, a 104V/55Ah pack, 68.3 mph and a 37-inch seat. An Australian distributor’s spec page for the same model publishes 22.5 kW but a 90V/48Ah (4,320Wh) pack, 520 N·m, a 940 mm (about 37-inch) seat, 290 mm of travel at both ends, and 110 km/h. We are not going to pretend to know which applies to a bike you are looking at. If battery voltage or suspension travel is decisive for you, ask for the numbers off the specific unit rather than trusting any general listing, ours included.
Sur-Ron Light Bee X / LBX: the one most people should start on
The Light Bee X is the bike that built Sur-Ron’s reputation, and it is still the right answer for a large share of buyers. At a published 125–130 lb it is light enough to pick up, load into a truck bed without a ramp, and wrestle out of a rut when you get it wrong. The roughly 32.6-inch seat means most adults can flat-foot it, and that single fact does more for a new rider’s confidence than any amount of power.
The tradeoff is real, though, and we would rather you hear it now than after delivery. Taller adults frequently describe the stock LBX as feeling small, with many adults finding it undersized in stock form. Seat risers and bar risers help meaningfully, and plenty of our customers fit them, but they do not turn it into a full-size machine.
Suspension is the other honest limitation. Roughly 7.8–7.9 inches of fork travel and a short-stroke rear shock are fine for trail riding and fire roads. They are not a match for the Ultra Bee if you are hitting jumps or fast, rough terrain. Ride it for what it is and it is superb.
Who we steer toward the Light Bee X
- Riders roughly 5’2″–5’9″, or anyone who wants both feet down.
- First-time dirt riders. This is the strongest case for a Sur-Ron for beginners.
- Tight, technical single-track and wooded property riding.
- Anyone who has to lift, hang, or transport the bike alone.
- Buyers who want the lowest entry cost into the platform.
We stock the Sur-Ron LBX new in Nardo Grey and White Phantom, plus the 2023 Sur-Ron X Bike, and we regularly have used Light Bee X and LBX units including a fairly used 2022 LBX. You can see current new Sur-Ron inventory and used Sur-Ron inventory as it changes.
Sur-Ron Ultra Bee: the full-size step up
The Sur-Ron Ultra Bee is not a hopped-up Light Bee. It is a different chassis aimed at a different rider. A published 35.8-inch seat height, 9.4 inches of fork travel and 9.4 inches of rear wheel travel put it in genuine dirt bike territory, and the 74V/55Ah pack with 12.5 kW peak is close to double the Light Bee’s output. Published top speed is 56 mph against 46.6–50 mph, and published range is 62 miles at 31 mph.
What that translates to on the trail is a bike that stops feeling nervous above 35 mph. The extra travel soaks up terrain the Light Bee skips across. The extra 57–61 lb of curb weight is noticeable when things go wrong, which is exactly why we do not recommend it as a first bike for a small or inexperienced rider.
The Ultra Bee’s multiple ride modes matter more than the marketing suggests. Detuned, it is manageable for a competent rider building up. It just does not solve the ergonomic problem — a 5’4″ rider on a 35.8-inch seat is on tiptoes, and no software mode fixes that.
Who we steer toward the Ultra Bee
- Riders roughly 5’9″ and up.
- Anyone with prior dirt bike or moto experience.
- Open desert, fire roads, faster trails, longer rides.
- Riders who found a Light Bee cramped or ran out of power on it.
We carry the 2025 SURRON ULTRA BEE new, and used Ultra Bee units come through regularly — currently including a used street-legal-configured Ultra Bee and a used Ultra Bee X off-road 2025.
Sur-Ron Storm Bee: full-size electric enduro
The Sur-Ron Storm Bee is a different class of machine again, and we will be direct: it is not a beginner bike and it is not a light-duty trail toy. Published peak power of 22.5 kW is roughly double the Ultra Bee. Published top speed on Sur-Ron’s UK site is 68.3 mph. It runs 21-inch front and 18-inch rear wheels — full-size dirt bike sizing — with a published 37-inch seat height.
Weight is where the Storm Bee asks something of you. Sur-Ron UK’s published curb weight is listed as 209/279 lb, and the Australian spec page lists 97 kg excluding battery with a 29 kg battery. Under any of those readings, this is a substantially heavier bike than either Bee, and it handles like one at low speed.
If you have ridden a 250 or 450 enduro and want the electric equivalent, the Storm Bee is a coherent answer. If you are cross-shopping it against a Light Bee because it has bigger numbers, it is the wrong bike. We stock the Sur-Ron Storm Bee 2023 new and used Storm Bee units when they come available.
The street legality question — read this before you buy
We will not tell you any of these bikes is street legal, because that is not a property of the bike. Whether you can plate a street legal Sur-Ron depends entirely on your state’s vehicle code and how the bike is configured.
In broad terms, states that allow registration typically want some combination of a DOT headlight with high and low beam, tail and brake light, turn signals, mirrors, a horn, a license plate mount with plate light, a speedometer, DOT-approved tires, and a VIN the DMV will accept. The specifics vary a lot — reporting on the topic notes that requirements differ enough between states that a bike legal in one may not be titleable in the next.
Arkansas is not California is not Colorado. Check with your own state DMV before you buy, and if plating the bike is the whole point of the purchase, confirm your state’s requirements first, then contact us so we can tell you exactly how a given unit is equipped. We would much rather answer that question before the crate ships.
New or used?
A used Sur-Ron is often the smarter buy, particularly for a first bike. These are mechanically simple machines — the wear items are tires, brake pads, chain, sprockets, and bearings, all cheap and available. The battery is the expensive component, and it is the one thing worth asking pointed questions about.
Every used bike we list is mechanically inspected and test-ridden by our staff before it goes up. That is not a warranty; it is a filter. If something is worn or non-original, we would rather tell you than have you discover it.
Buy new if you want the current battery and controller generation, factory-fresh consumables, and our 30-day return window. Buy used if you want more bike per dollar and are comfortable with a 14-day return window on an inspected machine. Both are legitimate. Our full range of Sur-Ron for sale sits alongside our broader dirt bike inventory if you want to widen the electric dirt bike comparison beyond one brand.
How buying from our shop works
We are an independent retailer in Little Rock, Arkansas. Full-size bikes ship in a wooden crate on a pallet by LTL freight, partially assembled, curbside delivery — $250 flat-rate to the 48 contiguous states. Curbside means the driver brings it to the end of your driveway, not into your garage, so plan for a second set of hands and a way to move a crated pallet.
Local pickup is free at 4509 W Dixon Rd, Little Rock, AR 72206, and if you are within driving distance we genuinely recommend it — you get to sit on the bike before committing, which resolves the sizing question faster than any article can. Details are on our shipping page, and common questions are answered on our FAQ.
So which Sur-Ron should I buy?
If you are still asking which Sur-Ron should I buy after all that, use this order of operations: fit first, terrain second, power last. Sit on the bike or measure your inseam against the published seat heights — 32.6 inches for the Light Bee X and LBX, 35.8 for the Ultra Bee, 37 for the Storm Bee. Then ask what you actually ride. Power is the easiest thing to grow into and the easiest to over-buy.
Most riders who buy a Light Bee X first do not regret it. A fair number who buy an Ultra Bee or Storm Bee first end up riding less than they expected because the bike intimidates them. If you tell us your height, experience, and where you ride, we will give you a straight recommendation — including telling you not to buy the more expensive bike.
