The Himiway D5 Pro (formerly the Zebra Pro) is a premium, all-terrain electric fat bike designed for riders who demand uncompromising durability, immense power, and a highly responsive ride. Built like an absolute tank but styled with seamless elegance, the D5 Pro bridges the gap between a heavy-duty off-road adventurer and a highly capable daily utility vehicle.
Whether you're conquering snowy mountain trails, riding on sandy beaches, or simply hauling groceries and carting kids across town, the D5 Pro delivers rock-solid stability. Its foundation is an upgraded 6061 aerospace-grade aluminum frame that is twice as thick as conventional e-bikes. Paired with puncture-resistant 26" x 4.0" Kenda K-shield fat tires, it effortlessly absorbs rough impacts and provides relentless grip across gravel, mud, and uneven pavement.
What truly elevates the D5 Pro is its advanced 500W Torque-Sensing Mid-Motor (peaking at 1300W). Delivering a massive 130Nm of torque directly to the drivetrain, it effortlessly powers up steep hills and provides a natural, intuitive pedaling experience that standard bikes simply can't match. This makes it perfect for riders seeking a balanced workout, or those who need smooth, predictable pedal assistance to conquer challenging terrain.
With a staggering 400 lb payload capacity and a seamlessly integrated 960Wh Samsung/LG battery, the D5 Pro provides up to 80 miles of range per charge for long-lasting, anxiety-free excursions. It comes fully equipped with premium components, including a 9-speed Shimano gear shift system, fade-free hydraulic disc brakes, an ultra-bright 500LM spotlight, and an integrated brake light to ensure absolute safety and control in any environment.
