HappyRun | G100 Pro Electric Bike 6000W Dual Battery, 72V Power

HappyRun Tank G100 Pro 72V Dual-Battery Moped Electric Bike - 6000W Peak Fat Tire E-Bike

Roll the throttle past halfway and the G100 Pro stops pretending it is a bicycle. A 6000W peak motor pushes you to 50 mph with the kind of low-end torque that pins you back into the seat on every launch. This is the upgraded successor to HappyRun's top-selling G100, built for experienced riders who have already outgrown entry-level e-bikes and want genuine motorcycle-level acceleration without licensing, insurance, or the weight penalty. Full suspension soaks up trail hits and potholed city streets alike, and oversized 203mm hydraulic disc rotors bring all of that speed back under control with a single firm squeeze.

The real advantage lives in the frame: a 72V 33Ah dual-battery system that delivers up to 78 miles on a single charge and slides out for indoor charging when you get home. No adapter cables, no dragging 90+ pounds to an outlet. The cockpit stays clean with an NFC tap-to-unlock ignition and a sunlight-readable color LED display that puts speed, battery status, and assist level right where you need them. At 68 inches long with a 33-inch seat height, the G100 Pro fits riders from 5'3" to 6'5" and still keeps both feet flat on the ground at stops. It is built to feel planted, not top-heavy.

Features

• 6000W Peak Brushless Motor - Delivers serious torque off the line and sustains speeds up to 50 mph, making the G100 Pro one of the fastest moped-class e-bikes available without a motorcycle license in most jurisdictions.
• 72V 33Ah Dual-Battery System (Removable) - Two batteries integrated into the frame provide up to 78 miles of range per charge. Both slide out independently for convenient indoor or workplace charging without moving the bike.
• Full Suspension (Front Fork and Rear) - Front and rear suspension travel absorbs roots, gravel washouts, potholes, and speed bumps, reducing fatigue and keeping the rear tire planted under hard acceleration.
• Hydraulic Disc Brakes with 203mm Rotors - Oversized rotors and professional-grade hydraulic calipers deliver progressive, fade-resistant stopping power matched to the bike's 50 mph top speed.
• NFC Tap-to-Unlock Ignition - No keys to lose or fumble with. Tap the NFC card to the display unit and the bike powers on, adding a layer of theft deterrence when parked.
• Sunlight-Readable Color LED Display - Large screen with integrated sun shade stays visible in direct sunlight, showing real-time speed, dual-battery levels, trip distance, and pedal-assist mode.
• 20 x 4.0 All-Terrain Fat Tires - Wide-contact rubber grips confidently across wet asphalt, packed dirt, sand, and light snow without requiring seasonal tire changes.
• Half-Throttle with 5-Level Pedal Assist - Half-throttle design prevents accidental full-power launches. Five PAS levels let you blend motor support with pedaling effort, from light exercise to full electric cruising.
