What instantly sets the Kingbull Jumper Go apart from the crowd is its low step-through frame combined with full suspension and 4-inch fat tires—a combo you rarely (if ever) see in a single e-bike.
This design makes the bike extremely easy to mount, while still giving you the comfort, traction, and control of a traditional hardtail fat tire bike.
Frame: 6061 aluminum, sturdy and oversized
Geometry: Comfortable upright position, suitable for riders 5'3" to 6'7"
Suspension: Absorbs bumps and potholes, smooth over light trails
Note: While the suspension is cushy and very comfortable for casual rides, it's not adjustable for compression or rebound, so it may bottom out under heavy impacts or if you're hauling close to max payload.
Motor & Performance
The 750W Bafang G063 hub motor is one of the strongest in its class, with 85Nm of torque. Whether you’re climbing steep hills, hauling cargo, or simply zipping past cars on your commute, this motor gets the job done—and does it smoothly, thanks to a built-in torque sensor.
Power Modes:
- Pedal Assist (Class 3) – Up to 28 mph
- Throttle Mode (Class 2) – Up to 20 mph
- 5 PAS Levels – Smooth power delivery, no jerkiness
Torque sensor = better ride feel. You pedal, and the power ramps up naturally, much better than the on/off feel of cheaper cadence sensors.
Ride Experience – City Streets to Dirt Bike Trails
We tested the Jumper Go on a mix of urban streets, gravel paths, and light trails, and here’s the verdict:
- In the city: Comfortable and controlled. The fat tires soak up cracks and cobbles. The step-through frame makes stop-start traffic effortless.
- Off-road/light trail: Fun and capable, but not built for jumps or serious MTB terrain. The suspension is better suited for comfort than performance.
- Cargo hauling: With 450 lbs capacity and a sturdy frame, it’s surprisingly effective for heavy grocery runs or child seats.
Warning: At 81 lbs, the Jumper Go is heavy. There is, however, a walk mode, which can be activated by long-pressing the "-" button.
Battery & Range – 960Wh of Real-World Mileage
With a Samsung 48V 20Ah battery (960Wh), the Jumper Go claims up to 80 miles of range—and it’s not exaggerating.
Real-world test results:
PAS 1–2 (Eco mode): ~70–80 miles
PAS 3–4 (Mixed riding): ~55–65 miles
PAS 5 / Throttle: ~35–45 miles
The battery is removable, key-locked, and IPX6 water-resistant, which is a significant advantage for both urban and outdoor riders.
Drawback: The battery lacks smart features and app connectivity—features you’d expect at this price range. No GPS, no remote lock, no diagnostics.
Brakes & Gearing
- Brakes: Tektro 4-piston hydraulic brakes (HD-E394) w/ 180mm rotors – easily one of the best in class.
- Drivetrain: Shimano 8-speed (Acera M310) with 13–32T cassette – crisp shifts, though under heavy torque it can feel stressed.
- Display: KB35H color screen – bright and simple, but lacks trip logging or mobile sync
- Extras: Integrated headlight, taillight, and electronic horn
The rear rack supports 150 lbs, perfect for food delivery, panniers, or a child seat. There are also fenders, a kickstand, and reflective sidewalls included stock.
Display, Controls & Features
The KB35H color LED display on the Kingbull Jumper Go is a clean, intuitive interface that gives you all the essential ride data at a glance.
It shows your speed, PAS level, battery percentage, trip distance, and total mileage in a bright, easy-to-read format—even in direct sunlight. The interface is responsive and easy to navigate using the handlebar-mounted control pad, making on-the-fly adjustments simple and safe.
While it lacks Bluetooth connectivity or app integration (a missed opportunity in this price range), it does include useful features like walk assist, headlight control, and error codes for quick diagnostics. Overall, it strikes a good balance between functionality and simplicity, without overcomplicating the riding experience.
Assembly & Support
Assembly: Arrives 85% assembled with tools included
Customer Service: Responsive and friendly, though Kingbull is still growing its service network
Warranty: 1-year limited, battery + electronics covered
