HappyRun Tank G70 Pro Dual-Motor Electric Cargo Bike - 5000W Peak All-Wheel-Drive Fat Tire E-Bike

*Does not come with cargo rack, must be purchased seperately*

Most cargo e-bikes ask you to choose between hauling power and ride quality. The G70 Pro skips that compromise entirely. A dual-motor system - one 2500W peak hub motor in the front wheel, another in the rear - delivers true all-wheel-drive traction with 5000W of combined peak power. Load up 330 pounds of kids, groceries, or gear, point it at a steep hill, and both wheels pull. That changes what a cargo bike can actually do. You feel it immediately on loose gravel, wet pavement, and inclines where single-motor bikes bog down and spin.

The frame is built around a swappable rear platform: bolt on the passenger seat for family rides, or swap it for a cargo rack rated to 50 lbs when you need to haul boxes and bags. A dual-battery system pushes range up to 85 miles on a single charge, and both batteries slide out for indoor charging. The seat height sits at 31.5 inches, low enough for riders as short as 5'1" to flat-foot confidently at stops even with a loaded bike. NFC tap-to-start ignition syncs with both iOS and Android so your phone becomes the key, and a color display stays readable in direct sunlight. Everything about this bike is designed to carry more, go further, and still feel manageable when you get off and park it.

Features

• Dual 2500W Hub Motors (5000W Combined Peak, All-Wheel Drive) - Front and rear motors engage simultaneously for superior traction on hills, loose surfaces, and wet roads. Under heavy cargo loads, AWD prevents rear-wheel spin and maintains forward momentum where single-motor bikes struggle.
• Dual-Battery System (48V 33Ah Total) - Two removable lithium-ion batteries deliver up to 85 miles of range per charge. Both slide out of the frame independently for indoor or workplace charging without moving the bike.
• Swappable Rear Seat / Cargo Rack - The rear passenger seat removes and replaces with a cargo rack rated to 50 lbs using a quick-release buckle system. Switch between family transport and grocery hauling in minutes, no tools required.
• Full Adjustable Suspension (Front and Rear) - Adjustable front fork and rear suspension let you tune ride stiffness based on load weight, keeping the bike composed whether you are carrying a child or riding solo on rough trails.
• Hydraulic Disc Brakes (Dual-Piston) - Dual-piston hydraulic calipers on both wheels deliver progressive, fade-resistant stopping power calibrated for heavy loads at speed. Confidence matters more when you are carrying passengers.
• NFC Tap-to-Start with Phone Sync - Tap the NFC card to power on, or sync the key to your iOS or Android phone. No physical keys to lose, and an added layer of theft deterrence when parked in public.
• Shimano 7-Speed Gear System - Mechanical shifting supplements the dual motors, letting you fine-tune cadence on flat roads or steep terrain without draining battery faster than necessary.
• 20 x 4.0 Puncture-Resistant Fat Tires with Reflective Strips - Reinforced sidewalls and puncture-resistant construction handle broken glass, gravel, and trail debris. Integrated reflective strips improve visibility for night riding without adding separate reflectors.
• Half-Twist Throttle with 5-Level Pedal Assist - Half-twist throttle prevents accidental full-power surges when loaded. Five PAS levels let you blend effort with motor support, from a light workout to full electric cruising under heavy cargo.
