FREESKY Swift Horse Ultra X-6E Electric Bike – 48V 35Ah Battery & 3500W Peak BAFANG Power
The FREESKY Swift Horse Ultra X-6E Electric Bike is the updated name for the Swift Horse model, now listed by FREESKY as the Swift Horse Ultra X-6E. The key specification update is its larger 48V 35Ah Samsung/LG lithium battery, which gives the Ultra version extended battery capacity compared with earlier Swift Horse Pro listings.
Built around a 3500W peak BAFANG brushless motor, 140Nm torque, full suspension, 26 x 4-inch fat tyres, Shimano 7-speed gearing and 180mm 4-piston hydraulic brakes, the Swift Horse Ultra X-6E is a powerful high-capacity fat tyre electric bike designed for demanding off-road/private-land use.
⚡ Power & Performance
The BAFANG brushless motor delivers up to 3500W peak power and 14140 N·m torque, giving the Swift Horse Ultra X-6E strong pulling performance on steep climbs, soft surfaces, and heavy-duty riding conditions. A 48 30A controller manages the power system, while the 0–5 pedal-assist levels allow the rider to adjust support as needed.
The manufacturer also references a UK speed-limit mode designed to restrict output and assistance. Because this is a high-power e-bike with a thumb throttle and peak motor output above standard EAPC limits, the legal notice below must be read carefully before purchase or use.
🔋 Battery & Range
The Swift Horse Ultra X-6E uses a 48V 35Ah lithium battery with Samsung/LG cells. This is the main update over the previous Swift Horse Pro specification, giving the Ultra version a larger battery capacity for extended ride time.
The rated range is 140–225 km (87–140 miles) under ideal pedal-assist conditions.
Range figures are based on ideal pedal-assist test conditions. Actual range varies depending on rider weight, load, assist level, throttle use, Terrain, gradient, wind conditions, temperature, tyre pressure, battery condition and riding style.
🛞 Tyres, Suspension & Ride Comfort
The 26 x 4-inch fat tyres provide a wide contact patch for stability, cushioning and grip across loose, uneven and mixed surfaces. The front suspension fork and rear suspension help absorb impacts and reduce vibration, while the 30.9 x 300mm alloy seatpost supports rider comfort.
💡 Controls, Display & Lighting
The LCD colour display shows key ride information, including pedal-assist level, headlight status, speed, battery level, and mileage. The bike also includes handlebar-integrated steering lights to support rider signalling.
🛡️ Braking, Safety & Build Quality
The Swift Horse Ultra X-6E uses 180mm 4-piston hydraulic brakes for strong, controlled braking performance. The upgraded 6061 aluminium frame, KMC chain, heavy-duty adjustable aluminium kickstand and full-suspension layout support a robust high-power e-bike build.
🔐 Security & Smart Features
The bike includes a thumb throttle, 0–5 pedal-assist levels, and an LCD colour display for control. FREESKY lists the Swift Horse Ultra X-6E as UL2849 certified for e-bike electrical safety.
🔌 Charger & Power Specification
The Swift Horse Ultra X-6E is supplied with a 3A smart charger. FREESKY lists the charger as supplied with both US standard and UK standard power cables.
