G4 Ultra Unboxing Guide: What to Do When Your New Scooter Arrives
Your KuKirin G4 Ultra has arrived. The box is in your hallway. The dual motors, the 1,200Wh battery, the 70 km/h top speed — all waiting inside.
But before you twist the throttle, take a breath. A few minutes of preparation now will make every future ride safer and more enjoyable.
This guide walks you through everything: what is in the box, how to assemble it, how to charge it, and what to check before your first ride.
What Is in the Box

Before assembly, confirm all parts are present.
-
Charger × 1 — 5A fast charger, 67.2V output
-
Instruction manual × 1
-
Front fender × 1
-
Rear fender × 1
-
Installation tool bag × 1, containing:
-
Hex wrenches × 3
-
Spare motor nut covers × 2
-
Handlebar fixing screws × 2
-
Front fender screws × 3
-
Rear fender screws × 2
-
Important: The scooter itself is not listed in the packing list because it is the main product. The accessories above are what you need for assembly.
Check for damage: Inspect the box for dents, tears, or water damage. If the box is damaged, photograph it before opening and check the scooter for visible damage.
Assembly Steps

The G4 Ultra requires minimal assembly. Most of the scooter is pre-assembled.
Step 1: Unfold the Scooter
Release the folding latch and lift the handlebar until the frame clicks into place. Confirm the folding mechanism is fully locked.
Step 2: Install the Handlebar
Align the handlebar with the stem and secure it using the handlebar fixing screws × 2 from the tool bag. Tighten evenly — do not over-tighten.
Step 3: Install the Front Fender
Attach the front fender using the front fender screws × 3. The fender protects you and the scooter from water and debris thrown up by the front wheel.
Step 4: Install the Rear Fender
Attach the rear fender using the rear fender screws × 2. This protects the rear wheel area and keeps mud and water away from the suspension.
Step 5: Check All Screws
Give every screw a final check. The handlebar, fenders, and folding mechanism should all be secure with no movement.
First Charge: Do This Before Riding

Charge the battery to 100% before your first ride.
This is important for two reasons:
-
It balances the battery cells for optimal performance
-
It ensures you start with maximum range
Charging time: 5–6 hours with the 5A fast charger.
Charging tips:
-
Charge indoors or in a shaded, well-ventilated area
-
Do not charge in direct sunlight or in a hot car
-
The charger LED turns from red to green when charging is complete
-
Unplug within 1–2 hours after the green light appears
Do not skip this step. A new battery performs best when it starts from a full, balanced charge.
Pre-Ride Safety Check
Before your first ride, complete this 60-second check.
1. Tyre pressure
-
Recommended: 340 kPa (50 psi) when cold
-
Check both tyres with a pressure gauge
-
Under-inflated tyres reduce range and stability
2. Brakes
-
Squeeze both brake levers — they should feel firm
-
Push the scooter and apply the brakes — it should stop smoothly
-
Check the 160mm discs for visible damage
3. Lights
-
Turn on the headlight and taillight
-
Test the brake light (should flash when braking)
-
Test the turn signals (left and right)
4. Folding mechanism
-
Confirm the latch is fully locked
-
Try to fold the scooter — if it moves, it is not secure
-
Check that all screws are tight
5. Display
-
Power on the scooter
-
Confirm the display shows speed, battery, and mode
-
Test the button functions (see our smart features guide)
Mode Selection: Start in ECO
The G4 Ultra has three riding modes: ECO, SPORT, and RACE. If you are new to high-performance scooters, start with ECO mode.
ECO mode (20 km/h):
-
Lowest speed — easy to control
-
Maximum range — up to 80 km
-
Best for learning the scooter's handling
SPORT mode (40 km/h):
-
Moderate speed — suitable for experienced riders
-
Balanced range — approximately 50 km
-
Good for daily commuting once you are confident
RACE mode (70 km/h):
-
Maximum speed — for experienced riders only
-
Reduced range — approximately 35 km
-
Only for private land or legal high-speed areas
The golden rule for new riders: Spend your first few rides in ECO mode. Get comfortable with the balance, braking, and turning. Then move up to SPORT. Save RACE for when you truly know the scooter.
First Ride Tips
Choose a safe practice area:
-
Empty car park
-
Wide open space
-
Quiet residential street with low traffic
-
Avoid slopes, busy roads, and rough terrain
Practice these skills first:
-
Getting on and off the scooter
-
Balancing at low speed
-
Gentle acceleration and braking
-
Turning in both directions
Wear protective gear:
-
CE EN 1078 certified helmet — always
-
Knee and elbow pads — recommended
-
Gloves — for grip and protection
Ride within your limits. The G4 Ultra is capable of 70 km/h, but that does not mean you should ride at 70 km/h on your first day. Build up gradually.
