D5 Pro ST / All-terrain Electric Fat Bike

The Himiway D5 Pro ST (Step-Thru) is a premium, all-terrain electric fat bike that seamlessly combines extreme durability and mid-drive power with the ultimate convenience of an accessible step-through frame. Designed for riders who want the rugged "tank-like" performance of a premium off-road bike without the hassle of swinging a leg over a high top tube, the D5 Pro ST makes all-terrain exploration accessible to everyone.

Whether you're cruising through hilly backroads, riding on sandy beaches, or running daily errands, the D5 Pro ST offers unparalleled stability and ease of use. Its foundation is an upgraded 6061 aerospace-grade aluminum step-through frame that is twice as thick as conventional e-bikes. This design provides massive structural integrity while making mounting and dismounting effortless—an absolute game-changer if you have limited mobility or are carrying a heavily loaded rear rack. Paired with puncture-resistant 26" x 4.0" Kenda K-shield fat tires, it delivers relentless grip and shock absorption across gravel, mud, and snow.

What truly sets the D5 Pro ST apart is its advanced 500W Torque-Sensing Mid-Motor (peaking at 1300W). Delivering a massive 130Nm of torque directly to the drivetrain, it flattens the steepest hills with ease. The intuitive torque sensor responds instantly to your pedaling effort, providing a smooth, natural riding experience that feels like a traditional bike but with superhuman strength—perfect for a balanced workout or injury recovery.

Despite its accessible design, the D5 Pro ST compromises nothing on heavy-duty utility. With a staggering 400 lb payload capacity and a seamlessly integrated 960Wh Samsung/LG battery, it provides up to 80 miles of anxiety-free range per charge. Premium components like a 9-speed Shimano drivetrain, fade-free hydraulic disc brakes, and an integrated auto-illuminating brake light ensure absolute safety and control wherever your journey takes you.
