Dual Motor Power Equipped with two high-speed brushless hub motors featuring star‑gear design, this dual motor electric bike delivers massive torque (2×98N·m) and a 45° climbing angle. Choose front‑wheel drive, rear‑wheel drive, or both simultaneously for unmatched off‑road climbing and urban commuting adaptability. The ultra‑low energy consumption and silent operation make it a powerful yet quiet ebike for any terrain. Long-Range Removable Battery The 48V 20Ah lithium‑ion battery offers a stable 50‑70 km range per charge (at 25 km/h). Equipped with comprehensive protection (overcharge, deep discharge, overcurrent, short circuit, overheating), this long‑range ebike battery can be charged on the bike or removed for indoor charging. Lightweight Aluminum Frame The high‑strength aluminum alloy frame undergoes high‑temperature shrinkage treatment for increased rigidity and reduced weight, minimizing vibration for a smoother ride. The double‑shoulder speed‑descending front fork (adjustable damping and lockable) provides a fat tire ebike experience, conquering rough trails while keeping you comfortable on city streets. 20×4.0 Fat Tires & Shimano Hydraulic Brakes Oversized 20×4.0 coarse‑tread tires with a 4 mm puncture‑resistant layer deliver superior grip on gravel, mud, or wet pavement, preventing slips and enhancing handling. The Shimano 7‑speed transmission and hydraulic disc brakes offer sensitive, reliable stopping power and smooth gear shifts, making this off‑road fat tire e‑bike safe and controllable in all weather conditions. Smart LCD Display & Versatile Riding Modes The 3.5‑inch full‑color LCD screen (IP54 waterproof) shows speed, battery level, gear position, and fault codes in real time. Switch among pure pedal, electric assist (1‑5 gears), and pure electric throttle modes, plus freely toggle between single and dual motor drive. The generous gift pack includes rear rack, fenders, lock, pump, cup holder, and installation tools – everything you need to start your electric bicycle adventure right away.
