Rambo Dominator UltraDrive

The Rambo Dominator UltraDrive is a full-suspension, mid-drive hunting e-bike built for the hardest backcountry miles: steep grades, loose rock and deep timber. Its Bafang Ultra Drive 1000W torque-sensing motor delivers 160Nm of torque with smooth, natural power on every climb.

Key Specs

  • Bafang Ultra Drive 1000W mid-drive, torque sensing
  • 160Nm of torque
  • Up to 32 mph
  • 48V battery with LG cells, available in 15Ah, 20Ah or 30Ah
  • Up to 65 miles of range with the 20Ah battery, up to 98 miles with the 30Ah
  • SRAM NX 11-speed drivetrain
  • 350 lbs load capacity

Full Suspension

A RockShox RL rear shock gives a smooth, consistent rear-end feel, balanced by the stiffness and strength of the RSK air fork for responsive front-end handling and predictable rear performance.

Bafang Ultra Drive Torque-Sensing Motor

This high-performance 1000W mid-drive motor tackles steep hills and challenging terrain with ease, and its 160Nm of torque provides strong acceleration and climbing assistance even with heavier loads. The torque sensor detects how hard you are pedaling, so power delivery feels smoother and more natural than with a cadence sensor.

SRAM NX 11-Speed

The 11-42T setup offers a wide 420% gear range: the 42T cog for easier climbs and the 11T cog for faster speeds on flats and descents.

Features

  • Tektro 4-Piston Hydraulic Brakes: Excellent stopping power for a heavier, faster e-bike.
  • LCD Display with Adjustable Class Settings: Tough and waterproof, showing power, speed, battery and mileage, with switchable Class 1, 2 or 3 modes.
  • Built-in Fenders and Rear Rack: Stable carrying space for panniers, bags and accessories.
  • Rambo Storm LED Lightbar: Toggle between white and green light, with wide beam patterns for better peripheral visibility.
