The verdict
The Storm Bee is where Sur-Ron stops making "fast bicycles" and builds an actual full-size electric motorcycle. It ties the Ultra Bee at the top of our board — a VoltRipper Score of 89/100 — but it earns that number very differently: a 104V system, a huge 5.7 kWh battery, a genuine 75 mph top end, and full-size moto ergonomics. At ~$8,999 and 280 lb, it is an expert's bike and a halo purchase, not a starter or a step-up. If you already know you want a real electric dirt bike — not a light-format e-moto — this is Sur-Ron's answer.
Who it's for — and who should skip it
Buy it if you're an experienced rider who wants full-size motorcycle performance, the biggest battery in the Sur-Ron line, and a machine that rides like a moto rather than an oversized bicycle.
Skip it if you're newer or smaller — 280 lb and 75 mph is a serious, heavy, fast bike that will punish a learner; budget-conscious — the Light Bee X or Ultra Bee delivers most of the real-world fun for thousands less; or you want something light and flickable (that's the whole point of the smaller Sur-Rons — the Storm Bee trades it away for size).
What makes it different: it's a real motorcycle
The Light Bee and Ultra Bee are light-format e-motos you can loft and toss around. The Storm Bee is not. It runs a 104V system, ~10 kW nominal / ~22.5 kW peak, a 5.7 kWh (104V, 55 Ah) pack — the largest in the range — and hits 75 mph, with a claimed 0–50 km/h in about 1.9 seconds. At 280 lb it has the mass, stance, and speed of a full-size dirt bike. This is a different class of machine from its stablemates, and buying it means wanting that difference on purpose.
Range: the honest answer
Sur-Ron doesn't publish an official range figure for the Storm Bee, so we won't invent one. What we can say: at 5.7 kWh it carries the biggest battery in the Sur-Ron family — more than double the Light Bee X's 2,520 Wh — so real-world range should be the strongest of the three. But a heavier, faster, higher-voltage bike also draws more, so don't assume the battery advantage translates one-for-one. Budget off real riding, not the pack size — see our range guide.
The ecosystem still applies
Even at the halo end, you get Sur-Ron's biggest advantage: the strongest parts availability, dealer network, and 5/5 rider community in the segment. A $9,000 bike you can actually service and upgrade beats a rival you can't — and it's a real point of difference against boutique halo brands with thinner support.
Where it costs you
- Weight. 280 lb is a lot of motorcycle — the opposite of Sur-Ron's light-and-flickable reputation.
- Price. ~$8,999 puts it in halo territory, closing on purpose-built electric-MX bikes.
- Expert-only. The combination of mass and 75 mph is genuinely not for beginners.
- Not street-legal as sold. It ships off-road (`street_legal: kit`); road use needs a kit and a state that allows it. Read our street-legal guide first.
The Sur-Ron ladder — and the Stark question
| Bike | VoltRipper Score | Price | Battery | Peak power | Top speed | Weight |
|---|---|---|---|---|---|---|
| Sur-Ron Storm Bee | 89 | $8,999 | 5,720 Wh (104V) | ~22.5 kW | 75 mph | 280 lb |
| Sur-Ron Ultra Bee | 89 | $6,499 | 4,440 Wh (74V) | ~24.5 kW | 59 mph | 195 lb |
| Sur-Ron Light Bee X | 83 | $4,400 | 2,520 Wh (72V) | 10 kW | 53 mph | 130 lb |
The Storm Bee and Ultra Bee tie at 89 for opposite reasons. The Ultra Bee wins on value and keeps the lighter, more manageable Sur-Ron character; the Storm Bee wins on outright size, battery, and top speed but asks $2,500 more and 85 more pounds for it. For most riders stepping up, the Ultra Bee is the smarter buy — the Storm Bee is for the rider who specifically wants a full-size electric motorcycle.
And if you're spending Storm Bee money, cross-shop the Stark Varg — a purpose-built electric motocross bike that's far pricier (roughly $13,000+) but is a dedicated race machine rather than a big trail bike. Different tools: the Storm Bee is the do-everything full-size Sur-Ron; the Stark is a competition-grade MX weapon.
Bottom line
The Sur-Ron Storm Bee is the full-size, motorcycle-class halo of the Sur-Ron line — the top of our board, and the right buy for an experienced rider who wants real size, speed, and battery without leaving the best-supported platform in the segment. It is not a beginner bike, a value pick, or a light-format e-moto. It's the one you buy when you know exactly what you want and you want the big one.
VoltRipper is spec-verified and data-driven — we do not claim hands-on testing of this bike. Specs and prices are cross-checked against the sources listed above and re-verified regularly; where a manufacturer figure (such as range) isn't published, we say so rather than estimate a spec number.
