Head-to-head
Altis Sigma vs Apollo (RFN) RFN Ares Rally Pro
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 |
|---|---|---|---|---|---|
| Altis Sigma Trail - Expert | 86 | $4,799 | 25 kW | 3.4 kWh | fastest electric dirt bike, expert trail riders |
| Apollo (RFN) RFN Ares Rally Pro Trail - Intermediate | 86 | $4,799 | 12.5 kW | 3.1 kWh | power-hungry riders, a higher-peak-kW Sur-Ron alternative |
What works
- Fastest verified bike in the catalog: 97.2V, 25 kW peak, and an 80 mph top-speed claim
- 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
What works
- Marketed as a 'Sur-Ron killer' — 12.5 kW peak 'rocket mode' is big power for the money
- Large 3.1 kWh removable battery, fast charging, and a headlight for kit-based street use
- Adjustable suspension and tortoise/rabbit ride modes
Trade-offs
- Newer brand with a smaller aftermarket than Sur-Ron/Talaria
- Top-speed claims vary widely (46–55 mph) — verify the exact model
- Range claim (100 mi) is an eco figure; expect far less ridden hard
