Head-to-head
Arctic Leopard XE Pro R vs Altis Sigma
Altis Sigma leads on current VoltRipper Score, but rider fit, legality, budget, and support still decide the smarter buy.
| Bike | Score | Price | Peak power | Battery | Best fit |
|---|---|---|---|---|---|
| Arctic Leopard XE Pro R Trail - Expert | 84 | $5,699 | 26.5 kW | 4.4 kWh | full-size enduro buyers who want value, Ultra Bee alternatives |
| Altis Sigma Trail - Expert | 86 | $4,799 | 25 kW | 3.4 kWh | highest top-speed claim, expert trail riders |
What works
- 26.5 kW peak output, 700 N.m torque, and a 74V/60Ah pack give it serious full-size enduro hardware
- 21/18 wheels and a 175 lb claimed weight make it a lighter alternative to the Ultra Bee/Komodo tier
- Undercuts many big-battery enduro rivals while still using established US dealer channels
Trade-offs
- Newer import brand with less community history than Sur-Ron, Talaria, or Stark
- Published speed and range figures vary by source, so real-world performance needs owner/test validation
- Warranty and long-term parts depth are less clear than the headline specs
What works
- Highest top-speed claim in the catalog: 97.2V, 25 kW peak, 80+ mph claimed for the fastest gearing (real-world ~70+ mph)
- Large 3,402 Wh Samsung 50S removable pack with a 3-hour full-charge claim
- Strong spec-per-dollar from a $4,799 manufacturer/REVRides price and multiple US dealer listings
Trade-offs
- Newer brand, so parts depth, resale, and owner history are far behind Sur-Ron or Talaria
- Off-road-only and expert-speed; this is not a beginner or casual trail bike
- Dealer prices and range language vary, so buyers should verify exact out-the-door price and current config
