Battery: 20Ah

The Himiway D5 Pro ST is the step-thru version of the D5 Pro, pairing the same torque-sensing mid-drive power and fat-tire capability with a low-step frame that's easy to mount and dismount. It's built for riders who want all-terrain performance without swinging a leg over a high top tube.

  • 500W torque-sensing mid-drive motor (1300W peak) puts power through the gears for efficient climbing and a natural, responsive feel, reaching up to 25 mph.
  • Low-step frame (22.4" standover) makes mounting and dismounting easy, ideal for riders carrying gear, with limited mobility, or who simply prefer step-thru access.
  • 48V 20Ah (960Wh) Samsung/LG battery delivers up to 80 miles of range, integrated and removable for security and convenient charging.
  • 26 x 4" Kenda K-Shield fat tires plus full suspension float over mud, snow, sand, and rough trails, with a lower center of gravity for added control.
  • Shimano 9-speed Altus drivetrain, hydraulic disc brakes, thumb throttle, and an LCD display with USB-C charging round out a premium build identical to the standard D5 Pro.

Best for: Riders who want the D5 Pro's mid-drive power and fat-tire capability in an easy-access step-thru frame, for all-terrain adventure, cargo hauling, and comfortable everyday riding.

What's included: Charger and manual.

Frequently Asked Questions

Is the D5 Pro ST less powerful than the standard D5 Pro? No. The ST shares the same motor, battery, and off-road specs. The only differences are the step-thru frame and a lower standover height. Choose based on frame preference.

Why choose the step-thru frame? The low-step design makes mounting and dismounting easy, which helps if you carry cargo, have limited mobility, or just prefer not to swing a leg over a high frame. It also lowers the center of gravity for added control.

What's the real-world range? Up to 80 miles on pedal assist and around 60 on pure electric power with the 960Wh battery. Terrain, load, and assist level affect it.

How capable is it off-road? Very. Full suspension, 4" Kenda fat tires, and mid-drive torque handle mud, snow, sand, and trails.

How fast does it go? Up to 25 mph. It weighs 79 lbs and fits riders 5'3" to 6'5".
