1. 1500W Peak Motor Built for Climbing

At the core of the QNUT BK20 electric bike is a brushless rear hub motor rated for high‑torque performance with 1500W peak output — quiet, efficient, and powerful enough to power through steep slopes. Twist the throttle for moped‑style acceleration, or use pedal‑assist for a more traditional e‑bike feel; either way, the climbing power stays consistent.

2. Fat Tires for Snow, Trail & Street

20×4.0‑inch wide tires with deep, puncture‑resistant tread grip loose surfaces — snow, dirt, gravel, mountain paths — while staying smooth and stable on pavement. The extra width and aggressive pattern make this bike as much an off‑road explorer as it is a daily commuter.

3. Long‑Range Removable 48V 18Ah Battery

A high‑capacity 48V 18Ah lithium‑ion battery delivers up to 60-90 miles per charge under pedal‑assist mode and detaches for easy indoor charging, so range anxiety isn’t part of the ride — whether it’s a daily commute or a weekend trail run. Fully UL 2849 certified for complete electrical‑system safety.

4. Switch Between Pedal‑Assist and Full Throttle

Two riding modes cover every scenario: pedal‑assist for a workout‑friendly, traditional e‑bike ride, or throttle‑only for motorcycle‑style cruising with zero pedaling required. Riders can switch on the fly depending on terrain and energy level. 7‑speed gearing further optimizes uphill and downhill performance.

5. Full Suspension Comfort, Built for Rough Terrain

Front suspension fork plus rear spring shock pairs with a thick cushioned vintage seat to soak up impacts from rocks, roots, and uneven trails — keeping long off‑road rides and daily errands equally comfortable.

6. Reliable Braking & Smart LCD Display

Front and rear dual disc brakes deliver responsive, dependable stopping power for both city streets and rough off‑road conditions. The backlit color LCD dashboard clearly shows real‑time speed, trip mileage, battery level, assist mode and fault codes for convenient day‑and‑night riding.

7. Safety & After‑Sales Support

UL 2849 full‑system safety certified to protect against over‑charge, short‑circuit and thermal‑runaway risks. The bike arrives 85% pre‑assembled with all needed tools included. 1‑year manufacturer warranty covers motor, battery, frame and core components for adult riders.
