Altis Sigma vs Sur-Ron Ultra Bee: Value Disruptor vs the Benchmark (2026)

The short answer

This is the sharpest value-versus-ecosystem decision in the class right now:

• Buy the Altis Sigma ($5,299, Score 90) if you want the most performance per dollar — the highest top-speed claim in our catalog, more power, and $1,200 in your pocket. You'll trade away some support and resale certainty.
• Buy the Sur-Ron Ultra Bee ($6,499, Score 94) if you want the safer ownership — the deepest support network, the widest pool of used buyers, and a bigger battery, in a bike that's still seriously fast.

The Altis wins the spec sheet convincingly. The Ultra Bee wins the ownership experience. Neither answer is wrong — it depends on what you value.

The disruptor and the benchmark

Sur-Ron more or less invented this category, and the Ultra Bee is its proven, do-everything flagship. The Altis Sigma is the new challenger that undercuts it on price while beating it on paper — the clearest example yet of the value brands pressuring the establishment. The interesting part is that both things are true at once: the Altis really is the better spec-per-dollar bike, and the Ultra Bee really is the safer one to own.

The core matchup

Head-to-head, factor by factor

Top speed → Altis, with a caveat. The Altis's 97.2V system is built for speed. On the spec sheet it's 80 mph claimed vs 59 — an enormous paper gap — and while its 80 mph is a best-case claim (real-world ~70+ mph, detailed in our review), even the honest figure leaves the Ultra Bee well behind. The Altis carries the highest top-speed claim we track, but not a verified "fastest bike, period" crown.

Power & torque → Altis. Slightly more peak power (25 vs 24.5 kW) and a huge 601 Nm of torque — and in a slightly lighter package (185 vs 195 lb), the Altis is the punchier, faster machine.

Price → Altis, decisively. $5,299 vs $6,499 — $1,200 less for more speed and power. On raw performance-per-dollar, nothing in this class touches it.

Battery & range → Ultra Bee on hardware. The Sur-Ron's 4,440 Wh pack is ~30% bigger than the Altis's, and that is the more useful hardware if you ride long. We can't give you the head-to-head miles, though: the Altis's ~35 mi is our hard-riding figure, and nobody has measured the Ultra Bee ridden hard. What the Ultra Bee has going for it is where the energy goes — the Altis spends more of it on speed.

Support & aftermarket → Ultra Bee, decisively. This is the whole case for the Sur-Ron. A decade of dealers, the deepest parts catalog in electric dirt, a massive owner community, and proven reliability. The Altis is newer and thinner here — you're more self-reliant for parts and service.

Resale → Ultra Bee. Sur-Ron holds value better than almost anything in the class; a newer brand like Altis is a bigger unknown when it's time to sell.

Score → Sur-Ron Ultra Bee (94 vs 90). Read that four-point gap correctly: the Altis's speed, power and lower price very nearly cancel the Sur-Ron's support and bigger battery, and fall four points short. One point is not a verdict: the Ultra Bee's support, resale, and proven ecosystem are exactly what a Score can't fully capture, and for many riders they still tip the decision the other way. Which factor matters more is your call.

Which should you buy?

• Max speed/spec claim, max power, best price, and you can self-support: Altis Sigma — the spec-per-dollar champion with the highest paper top-speed number we list. (Full review →)
• Best support, deepest used demand, bigger battery, proven ecosystem: Sur-Ron Ultra Bee — the safer buy, still seriously fast, and four Score points clear of the Altis. (Full review →)
• You want full-size over top speed: consider the Sur-Ron Storm Bee instead — here's the Ultra Bee vs Storm Bee call.

The honest bottom line

The Altis Sigma is the better bike on paper: more power, the higher top-speed claim, and $1,200 cheaper — though it finishes four points behind the Ultra Bee on the Score. If you chase performance-per-dollar and you're comfortable being more self-reliant on parts and service, it's a phenomenal buy and one of the headline bikes on our fastest list. But the Sur-Ron Ultra Bee makes its case exactly where the spec sheet is silent — support, resale, community, and a bigger battery — and with the Ultra Bee four points clear on the Score, for a lot of riders that peace of mind is worth $1,200. Buy the Altis for the specs; buy the Ultra Bee for the ownership.
