HappyRun | G70 Electric Cargo Bike 2000W Dual Battery, Long Range

HappyRun Tank G70 Electric Cargo Bike - 48V 38Ah Dual-Battery Fat Tire Family E-Bike

Strap your kid into the rear seat, load the panniers with groceries, and ride home without thinking about the battery. The Tank G70 is a purpose-built cargo e-bike with a 48V 38Ah dual-battery system that delivers up to 85 miles on a single charge - one of the longest ranges in its class. A 1000W continuous motor with 2000W peak output moves you and up to 330 pounds of combined rider, passenger, and cargo weight at speeds up to 36 mph, with enough low-end torque to keep momentum on hills without downshifting. Full adjustable suspension, hydraulic disc brakes, and a low 31.5-inch seat height make it feel stable and predictable even when fully loaded, which matters most when you are carrying someone who trusts you.

The rear platform converts in minutes without tools: passenger seat for family rides, or a cargo rack rated to 50 lbs for hauling boxes, bags, and gear. Both batteries slide out of the frame for indoor charging, so you never have to wrestle the entire bike to an outlet. NFC tap-to-start ignition syncs with iOS and Android, turning your phone into the key and eliminating one more thing to lose track of on a busy morning. The color display stays readable in direct sunlight, and integrated reflective strips on the 20x4.0 fat tires add visibility for early-morning commutes and after-dark errands. Every design decision on this bike answers the same question: can a parent or commuter depend on it daily without friction?

Features

• 48V 38Ah Dual-Battery System (Removable) - Two lithium-ion batteries deliver up to 85 miles of range per charge, among the highest in the cargo e-bike category. Both slide out independently for indoor charging at home or work.
• 1000W Motor (2000W Peak) - Continuous 1000W output handles loaded climbs and sustained cruising at up to 36 mph, while 2000W peak power provides responsive acceleration from stops and on inclines.
• Swappable Rear Seat / Cargo Rack - Quick-release buckle system lets you swap between the two-up passenger seat and a 50 lb-rated cargo rack in minutes. No tools, no hassle - switch configurations based on the day's needs.
• Full Adjustable Suspension (Front and Rear) - Front fork and rear suspension with adjustable preload let you tune ride stiffness based on whether you are riding solo, carrying a passenger, or hauling a loaded rack over rough roads.
• Dual-Piston Hydraulic Disc Brakes - Consistent, fade-resistant stopping power across both wheels. Progressive lever feel gives you confident control at speed, especially critical when braking with a loaded bike or a passenger on the back.
• NFC Tap-to-Start with Phone Sync - Tap the NFC card or use your synced iOS/Android phone to power on. No physical keys to dig out of a pocket while holding a helmet and a toddler.
• Shimano 7-Speed Gear System - Mechanical shifting lets you manage cadence across flat roads, hills, and trails, extending battery life by supplementing motor power with efficient pedaling.
• 20 x 4.0 Puncture-Resistant Fat Tires with Reflective Strips - Reinforced construction handles broken glass, gravel, and seasonal debris. Integrated reflective strips provide low-light visibility without bolt-on reflectors that rattle loose.
• Half-Twist Throttle with 5-Level Pedal Assist - Half-twist design prevents accidental full-power surges when loaded. Five PAS levels let you choose between zero-effort electric cruising and a light pedal workout that still gets you there on time.
