Sur-Ron STORM-BEE
Sur-Ron Storm Bee for sale
Liquid-cooled, 22.5 kW peak, 104V. Full-size motocross.
The Storm Bee is a full-size electric motocross machine with a liquid-cooled mid-drive and a 104V removable pack. It is the largest and most powerful bike in the Sur-Ron lineup and is intended for experienced riders on closed courses and OHV terrain. Figures come from the Sur-Ron owner’s manual for vehicle model QL10000DY.
- Full-size 21/18 motocross chassis
- Liquid-cooled motor, 22.5 kW peak, 520 N·m
- 104V 55Ah removable pack
- 47 mm inverted fork, 11.4 in travel
Sur-Ron Storm Bee top speed, range and power
The Sur-Ron Storm Bee top speed is 68 mph, and it will cover up to 75 miles on a charge, from a 22.5 kW peak motor rated at 10 kW continuous producing 520 N·m at the rear wheel. It weighs 280 lb with a 37 in seat.
Peak output is a burst figure — on a long climb or in deep sand you are riding the 10 kW continuous rating, which is the honest number to compare between machines. The pack is removable, so it charges indoors and a second one doubles your ride day.

Configuration
One machine, more than one wheel set. The frame, battery and motor are the same across these — what changes is what it rolls on, and what that does to the specification.
The machine as we sell it in the US: 21-inch front, 18-inch rear, knobby off-road tyres. Sur-Ron ships the North American Storm Bee F off-road only, with a headlight and number plate in the box.
The 4 photographs in the gallery at the top of this page are this configuration.

Who the Sur-Ron Storm Bee is for
A good fit if you are
- Experienced riders who want a full-size electric motocross bike, not a light e-moto
- Motocross-style riding, jumps and sustained high-speed work
- Riders who need real continuous output — 10 kW, the highest in the Sur-Ron range
- Anyone wanting maximum range: 75 miles from a 104V 55Ah pack
- Taller riders comfortable with a 37 in seat and a 21 in front wheel
Look elsewhere if
- Anyone who has not ridden a full-size dirt bike before
- Tight woods riding, where 280 lb is punishing
- Riders under about 5'11", realistically
- Anyone who has to load it alone without a ramp and a plan
What it is like to ride
The Storm Bee is the only machine here that a motocross rider would recognise as a proper dirt bike rather than an e-moto that grew up. 11.4 in of travel on a 21/18 wheel combination, liquid cooling so it holds output instead of derating, and 10 kW continuous behind the 22.5 kW peak. It rewards commitment and punishes hesitation. At 280 lb it is the heaviest thing either brand makes and it demands a competent rider — but for anyone who actually rides at that level, nothing else in this catalogue does the job.
Sur-Ron Storm Bee price
The Sur-Ron Storm Bee is $7,500 . That is firm US retail, benchmarked against live US dealer listings — freight is quoted separately against your destination.
It is the most expensive machine we carry, and the pack is most of the reason: 104V 55Ah is roughly 5.7 kWh, more than four times the energy of a Hyper Bee.

Parts for this bike
We do not yet hold parts specific to the Sur-Ron Storm Bee. Our OEM lines cover the Light Bee and Talaria platforms, and we will not list a component as fitting this machine on the strength of a shared dimension — that is how people end up returning things. 49 consumables and tools in our catalogue carry no fitment because none applies, and those work on it.

Common questions
- What is the Sur-Ron Storm Bee top speed?
- The Sur-Ron Storm Bee has a top speed of 68 mph, from a 22.5 kW peak motor rated at 10 kW continuous and 520 N·m at the rear wheel. Expect less into a headwind, uphill, on soft ground or with a heavier rider — that is true of every machine in this class.
- How much does the Sur-Ron Storm Bee cost?
- The Sur-Ron Storm Bee is $7,500. That is our firm US retail price, checked against live US dealer listings — not an indicative figure or an MSRP we hope to hit.
- How far will the Sur-Ron Storm Bee go on a charge?
- Up to 75 miles from its 104V 55Ah pack, depending on terrain, rider weight and ride mode. The battery is removable, so you can charge it indoors, store it at sensible temperature over winter, and run a second pack for a double ride day. A full charge takes about 4 hours.
- What is the seat height of the Sur-Ron Storm Bee?
- 37 inches, and the bike weighs 280 lb. Seat height decides suitability more often than power does, so if you are between models it is the number to compare first. Maximum payload is 220 lb.
- Is the Sur-Ron Storm Bee street legal?
- No. This is a high-powered electric off-road motorcycle and is not street legal in most US jurisdictions in stock form. It is intended for private land and designated OHV riding areas. California SB 586 created an "eMoto" classification effective 1 January 2026 — it classifies these machines, it does not make them street legal.
- Sur-Ron Storm Bee or Talaria Sting MX5 Pro?
- The Sur-Ron Storm Bee is 22.5 kW and 68 mph at 280 lb, on a 37 in seat. The Talaria Sting MX5 Pro is 13.4 kW and 60 mph at 163 lb, on a 33.1 in seat. Weight and seat height usually decide this, not power — we compare them side by side if you want the detail.
