Sur-Ron Light Bee X vs Ultra Bee

The 2026 Sur-Ron Light Bee X and the Sur-Ron Ultra Bee are both electric dirt bikes, and neither is a Class 1, 2, or 3 bicycle. The MY26 Light Bee sheets this desk already filed, Sur-Ron UK, Sur-Ron Canada, and Traction Bikes, say 10 kilowatts peak, a 72-volt 35-amp-hour pack, 130 pounds, and a claimed 50 mph. The Ultra Bee cards that agree say 24.5 kilowatts in Turbo, a 74-volt 60-amp-hour pack, and 195 pounds. Seventy-two times 35 is 2,520 watt-hours. Seventy-four times 60 is 4,440. Twenty-four and a half minus 10 is 14.5 kilowatts. One hundred ninety-five minus 130 is 65 pounds. Those gaps are the shopping problem. A blog that still prints 6 kilowatts and 110 pounds is describing an older Light Bee, not this MY26 sheet.

Fourteen and a half kilowatts, and 1,920 watt-hours

Four thousand four hundred forty minus 2,520 is 1,920 watt-hours. The Ultra pack is the larger tank. It is not twice the Light Bee pack: twice 2,520 would be 5,040, and 5,040 minus 4,440 is 600 short of double. The peak is the other way. Twice 10 kilowatts is 20. The Ultra Turbo line is 24.5, which is 4.5 past double, and Canada’s standard mode is 21.5, which is 1.5 past double. Wheel torque on the two sheets is 295 against 520 newton-meters. Five hundred twenty minus 295 is 225. Both lines say at the wheel. Do not put a motor newton-meter from a different bike in that subtraction. The motor page is why a peak is not the hangtag, and 10 kilowatts is already not a 750-watt bicycle.

Sixty-five pounds is the lift

One hundred ninety-five minus 130 is 65 pounds, if both claims hold. This desk did not put either bike on a scale. The Light Bee page already says the Ultra is the wrong bike if you still want to lift it into a van. Sixty-five pounds is that sentence with the arithmetic left in. Seat height on the Light Bee sheet is 830 mm. The Ultra page this desk filed does not print a seat height, so this comparison will not invent one. Fork travel is also not one unit: the Light Bee sheet says 200 mm of fork, and Voro’s Ultra block says 9.4 inches of travel. Those are not the same measurement.

Fifty, twenty, fifty-nine, and sixty-eight are not a top speed

The Light Bee claim that the UK and Canada sheets share is 50 mph. The Ultra Bee does not have one speed. Canada prints 59. Voro’s US product page says the bike ships at 20 mph, and the same page claims 87 miles at 25 mph. A UK MY26 HP X listing says 68 mph. Fifty-nine minus 50 is 9, and that subtraction is only legal if the crate is the Canada Ultra and the MY26 Light Bee, not the US governor and not the UK 68. Do not average 20, 50, 59, and 68. The 0-to-31 claims are 2.5 seconds on the Light Bee Canada line and 1.84 seconds on Voro’s July Ultra note. This desk did not hold either watch. Range claims are also different tests: Light Bee’s sheet says 46.6 miles at 24.85 mph, and Pit Bike USA’s owner pile is 25 to 32 miles of mixed Sport. Ultra’s Voro page says 87 miles at 25 mph, and Voro’s July note says Surron claims about 71.5 miles at 31 mph. The range page is why those miles do not subtract.

A 20 mph governor on a US Ultra cart is a setting. It is not proof the Light Bee is the faster bike, and it is not Class 2.

Rotors, then the third Sur-Ron

Both sheets say four pistons. The Light Bee rotor line is 203 mm. Voro’s Ultra line is 240 mm. Two hundred forty minus 203 is 37. That is a spec gap, not a fade test. The brake page is the Light Bee story, including the people who later bolt Ultra calipers onto a Light Bee. The primary is not the same part either: belt plus chain on the MY26 Light Bee, and the Ultra page does not reprint that belt sentence.

There is a third chassis. The Light Bee 2 is not this Light Bee X. Canada’s card for that one prints 24 kilowatts in Turbo, 143.30 pounds, and a 78.54-volt 45-amp-hour pack labeled 3.53 kWh. Twenty-four is half a kilowatt under the Ultra’s 24.5, on a bike the Canada card weighs at 143.30 pounds instead of 195. One hundred ninety-five minus 143.30 is 51.7. Shop that page if the question was “24 kilowatts without the 195-pound bike,” not if the question was this one.

Which one, if the crate matches the sheet

Buy the Light Bee X if you want the 130-pound trail bike, the parts catalog, and 10 kilowatts, and you can live with a claimed 50 rather than a 24.5-kilowatt Turbo mode. Buy the Ultra Bee if you want the 4,440-watt-hour pack and the 24.5-kilowatt line, and you can lift 195 pounds or you are not lifting it alone. Do not buy either as a bicycle. The class chart stops at pedals and 750 watts. The Talaria MX4 fight is the other Light Bee comparison, 8 kilowatts and about 145 pounds on that page, and it is not this Ultra. The invoice is the cart in front of you. A Canada list, a Voro tag, and a Rider Guide spread are three prices.
