HappyRun Tank G70 Electric Cargo Bike - 48V 26Ah Dual-Battery Fat Tire Family E-Bike (UL 2849 Certified)

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 26Ah dual-battery system (13Ah top + 13Ah bottom) that delivers up to 85 miles on a single charge - one of the longest ranges in its class. A 750W motor with 2000W peak output and 110 Nm of torque moves you and up to 330 pounds of combined rider, passenger, and cargo weight at speeds up to 20 mph, with enough low-end torque to keep momentum on hills without downshifting. Full adjustable suspension, dual-piston 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. Front and rear sequential turn signals, a 160-lumen headlight, and a braking-indicator taillight keep you visible and predictable in traffic, while integrated reflective strips on the 20x4.0 fat tires add visibility for early-morning commutes and after-dark errands. The entire electrical system is UL 2849 certified, so you get industry-leading battery and electrical safety with every ride.

Features

• 48V 26Ah Dual-Battery System (Removable) - Two lithium-ion batteries (13Ah top + 13Ah bottom) 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.
• 750W Motor (2000W Peak) with 110 Nm Torque - Delivers strong, responsive acceleration from stops and on inclines, with the low-end torque to handle loaded climbs and sustained cruising at up to 20 mph.
• UL 2849 Certified - The complete e-bike - motor, 26Ah battery, controller, and charger - has passed rigorous UL 2849 safety testing for fire and electrical protection, complying with current U.S. federal and municipal regulations.
• 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 (160mm Rotors) - Consistent, fade-resistant stopping power front and rear with 160mm rotors. 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.
• Integrated Lighting & Turn Signals - 160-lumen LED headlight, braking-indicator taillight with steady/flash modes, and front and rear sequential turn signals for clear, predictable road presence.
• 7-Speed Gear System - Mechanical 7-speed 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.
