Get ready for a full-suspension fat tire eBike built around serious power, automatic shifting, and the flexibility to ride farther. The Juggernaut Ultra FS Pro AUTO combines the proven Bafang Ultra M620 mid-drive with a new Bafang A510 5-speed automatic internally geared hub, giving you the power to tackle demanding terrain without the need to constantly manage your gears.

Features:

• 1000W Bafang Ultra M620 Mid-Drive Motor: Delivers strong, responsive power through the bike's gearing, giving you the capability to tackle steep climbs, rough trails, and heavy loads.
• Bafang A510 5-Speed Automatic Hub: Automatically shifts through five internally geared ratios as your speed and terrain change, keeping the M620 in a useful gear without constant manual shifting.
• 160Nm of Torque: Provides the low-speed pulling power needed for steep climbs, technical terrain, and carrying heavier loads.
• 265lb Load Capacity: Supports you and your gear without compromising the bike's intended performance.
• On-Demand Throttle: Access motor assistance without pedaling when you need an extra boost from a stop, on a climb, or through challenging terrain.
• Cadence + Torque Sensor: Combines pedal movement with rider input to deliver responsive, controlled assistance that feels natural under power.
• 52V 17Ah Battery: Includes a 52V 17Ah battery and charger, with the ability to add a second battery for substantially more available capacity and longer rides.

Benefits:

• Automatic Shifting: Let the A510 manage gear changes while the Ultra M620 delivers the power, so you can focus more on riding and less on drivetrain management.
• Serious Climbing Capability: The Bafang Ultra M620's high torque output works through five automatically selected gears, giving the motor useful gearing as terrain gets steeper.
• Extended Range: Start with the included 52V 17Ah battery and add a second battery when your rides demand more capacity.
• Full-Suspension Control: Combine powerful motor assistance with the stability and comfort of a full-suspension fat tire platform across rough and uneven terrain.
• Versatile Performance: From technical trails and loose surfaces to everyday riding, the combination of automatic gearing, high motor output, and wide tires gives you the flexibility to handle changing conditions without constantly adjusting the bike.

The Juggernaut Ultra FS Pro AUTO brings together Ultra M620 power, A510 automatic shifting, full suspension, and dual-battery capability in one platform built for riders who want substantial performance without unnecessary drivetrain management.
