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

  • 15 kW peak and 65+ mph — a big step above the base Mantis X for ~$4,499
  • App-tunable Eco/Sport/Race modes, DOT hydraulic brakes, and IP66/IP55 sealing
  • A real 1-year / 1,000-mile power-system warranty

Trade-offs

  • 65 mph / 15 kW is a lot of bike for newer riders
  • Heavier (~165 lb) than a Sur-Ron
  • Younger brand than Sur-Ron/Talaria with a smaller aftermarket
  • Hands-on testing has flagged slick stock knobbies on pavement and unused turn-signal controls
