D5 Pro ST / All-terrain Electric Fat Bike [Himiway]

Overview

The Himiway D5 Pro ST is a premium step-through all-terrain electric fat-tire bike engineered for riders seeking power, comfort, and versatility — whether cruising city streets, tackling sandy beaches, gravel roads, snowy trails, or hauling cargo. With a durable 6061-aluminum frame, torque-sensor mid-drive motor, large 960 Wh battery, and fat 26″×4″ tires, it blends stability, strength, and long-range performance in a user-friendly package.

Motor, Battery & Performance

• Motor: 500 W mid-drive motor — optimized for torque and efficient power delivery on varied terrain.
• Battery: 48 V, 20 Ah (~960 Wh) Samsung/LG lithium-ion battery — offers extended range and consistent performance.
• Maximum Range: Up to ~80 miles per charge (pedal-assist, under optimal conditions).
• Top Speed: Around 20+ mph (throttle or assist, depending on settings and local laws).
• Max Payload (rider + cargo): Up to 400 lb — supports heavier riders and load-heavy trips or cargo hauling.

Frame, Tires & Ride Geometry

• Frame: 6061-aluminum step-through frame — easier mounting/dismounting and confident handling for varied riders.
• Front Suspension: RST GUIDE-26 alloy fork, 100 mm travel — helps smooth out bumps and rough terrain on front wheel.
• Tires & Wheels: 26″ × 4.0″ fat tires on robust rims — provide excellent traction, comfort, and stability on sand, snow, gravel, mud, or uneven surfaces.

Drivetrain, Brakes & Control

• Gearing: Multi-speed drivetrain (typically 9-speed) — offers flexibility for hills, mixed terrain, or pedal-assist balancing vs manual effort.
• Brakes: Hydraulic or quality disc brakes (as equipped) — strong, reliable stopping power even under heavy loads or off-road conditions.
• Assist & Sensor: Torque-sensor pedal assist for natural, responsive power delivery that scales with your pedaling effort.
• Throttle Option: Provides motor-only power when needed — ideal for hills, heavy loads, or ease of commuting without pedaling.

Use Cases & Utility

• All-terrain off-road riding — sand, snow, gravel, or trails where fat tires and stable geometry shine.
• Cargo hauling or heavy-load transport — with 400 lb payload capacity, it's suited for gear, groceries, tools, or cargo racks.
• Commuting & urban riding — powerful motor and fat tires make it comfortable and stable even on rough city roads or mixed surfaces.
• Adventure and exploration — long-range battery and stable ride make it great for long trips, overlanding, and remote-route riding.
• Accessible riding — step-through frame design lowers the entry barrier for easier mount/dismount and comfortable posture.

Why D5 Pro ST Stands Out

• Balanced combination of mid-drive torque, fat-tire stability, and high-capacity battery gives versatile, powerful ride in all conditions.
• Step-through geometry enhances accessibility and comfort, especially for riders who prefer easier mounting and dismounting.
• High payload capacity and robust construction make it practical for cargo, errands, and utility use, not just recreation.
• Fat tires and sturdy suspension fork deliver confidence and control across rough or unpredictable terrain types.
• Large range and reliable power make it a solid all-around choice for long-distance rides, commuting, or multi-terrain adventures.
