The short answer
This is the sharpest value-versus-ecosystem decision in the class right now:
- Buy the Altis Sigma ($4,799, Score 86) if you want the most performance per dollar — the fastest bike in our catalog, more power, and $1,700 in your pocket. You'll trade away some support and resale certainty.
- Buy the Sur-Ron Ultra Bee ($6,499, Score 89) if you want the safer ownership — the deepest support network, best resale, 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
| Altis Sigma | Sur-Ron Ultra Bee | |
|---|---|---|
| VoltRipper Score | 86 | 89 |
| Price | $4,799 | $6,499 |
| Peak power | 25 kW | 24.5 kW |
| Top speed | 80 mph | 59 mph |
| System voltage | 97.2V | 74V |
| Torque | 601 Nm | — |
| Battery | 3,402 Wh | 4,440 Wh |
| Real-world range | ~35 mi | ~40 mi (est.) |
| Weight | 198 lb | 195 lb |
| Support & resale | Newer, thinner | Deepest in class |
Head-to-head, factor by factor
Top speed → Altis, decisively. 80 mph vs 59 is a 21 mph gap — enormous. The Altis's 97.2V system is built for speed, and it's the fastest bike in our entire catalog. If outright pace matters, this is a blowout.
Power & torque → Altis. Slightly more peak power (25 vs 24.5 kW) and a huge 601 Nm of torque. In a bike of essentially identical weight, the Altis is the punchier, faster machine.
Price → Altis, decisively. $4,799 vs $6,499 — $1,700 less for more speed and power. On raw performance-per-dollar, nothing in this class touches it.
Battery & range → Ultra Bee. The Sur-Ron's 4,440 Wh pack is ~30% bigger, and it does an estimated ~40 real miles to the Altis's ~35. If you ride long, the Ultra Bee's bigger battery is the more useful hardware. (The Altis spends its energy on speed; the Ultra Bee banks more of it as range.)
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 → Ultra Bee (89 vs 86). Read that gap correctly: it's not saying the Altis is slower or weaker — it's faster and stronger. It's saying the Ultra Bee's support, resale, and bigger battery outweigh the Altis's price and speed in the balanced Score. Which factor matters more is your call.
Which should you buy?

- Best support, best resale, bigger battery, proven ecosystem: Sur-Ron Ultra Bee — the safer buy that's still seriously fast, and the higher Score. (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 — and it isn't close: more power, 21 mph more top speed, and $1,700 cheaper. If you chase performance-per-dollar and you're comfortable being more self-reliant on parts and service, it's a phenomenal buy and our fastest pick for a reason. But the Sur-Ron Ultra Bee earns its higher Score where the spec sheet is silent — support, resale, community, and a bigger battery — and for a lot of riders that peace of mind is worth $1,700. Buy the Altis for the specs; buy the Ultra Bee for the ownership.
VoltRipper is independent — we don't sell Altis, Sur-Ron, or any bike, and our Score is based on verified specs, not who pays us. We disclose affiliate links before you click them, and we're spec-verified/data-driven rather than hands-on until first-hand testing exists.
FAQ
Is the Altis Sigma better than the Sur-Ron Ultra Bee?
On raw specs, yes — the Altis makes slightly more power (25 vs 24.5 kW), is dramatically faster (80 vs 59 mph), and costs $1,700 less. But the Ultra Bee scores higher on our board (89 vs 86) because of Sur-Ron's unmatched support, aftermarket, and resale. The Altis is the better spec-sheet bike; the Ultra Bee is the safer thing to own. It's a genuine values decision.
Why does the Ultra Bee score higher if the Altis is faster and cheaper?
Because the VoltRipper Score weights support, resale, and ecosystem — not just performance. The Altis wins decisively on raw performance-per-dollar, but Sur-Ron's decade-deep aftermarket, dealer network, proven reliability, and strong resale are worth real points. Fast and cheap is a big part of the story, but it isn't the whole story of living with a bike for years.
Is the Altis Sigma reliable and well-supported?
The hardware is genuinely impressive — 97.2V, 601 Nm of torque, 80 mph — but it's a newer platform without Sur-Ron's ten years of parts, dealers, and community. You're more on your own for service and spares. If you're handy and value performance-per-dollar, that's fine; if you want a proven support network and easy resale, that's the Ultra Bee's edge.
Which is faster, the Altis Sigma or the Sur-Ron Ultra Bee?
The Altis, decisively — 80 mph versus 59, thanks to its 97.2V system (against the Ultra Bee's 74V). It's actually the fastest bike in our entire catalog, quicker even than the full-size Storm Bee and the Stark Varg on top speed. The Ultra Bee is quick, but outright speed is the Altis's headline advantage.
