the HYPER GOGO Challenger 12 arrives 85 percent pre-assembled, so most of your time is spent fitting the front-end, styling parts and verifying electrical plugs.
Clear work space, the two included Allen keys, a #2 Phillips, a 10 & 13 mm wrench and 20–30 minutes are all you really need.
Steps below mirror the official video and manual yet add pro tips gathered from recent owner feedback and factory blogs. Ride-ready testing, optional training-wheel mounting and long-term care round out the guide.
Before You Start
Unboxing & Parts Check
-
Lay down the carton’s foam sheet to protect the paint.
-
Confirm you have: frame (rear wheel pre-installed), front wheel, handlebar, front fender, simulated fuel-tank shell, charger, hardware blister pack, two pedals and user manual.
-
Inspect wiring pigtails for bent pins while everything is still loose.
Workspace & Safety
-
Keep small screws away from children; the bike is rated for riders up to 65 kg but parts are still pocket-size.
-
Disconnect the battery (yellow bullet plug under the seat) until Step 7 to avoid accidental throttle blips.
Tools You’ll Need
| Task | Tool | Torque – feel |
|---|---|---|
| Wheel axle | 13 mm wrench | snug + ½ turn |
| Fender/fuel-tank screws | 4 & 5 mm Allen | firm wrist |
| Pedals | 15 mm spanner | “kiss” tight |
| Training-wheel kit (optional) | 10 mm wrench | same as axle |
(Allen keys ship in the box; wrenches are common household sizes.)
Video Tutorial

Step-by-Step Assembly
1. Deploy the Kickstand
Flip the stand down so the frame is upright before you work.
2. Install the Front Wheel
-
Slide the wheel between forks, making sure spacers stay outside the bearings.
-
Tighten axle nut evenly—spin the wheel; it should coast 3-4 seconds without rubbing.
3. Fit Both Pedals
Each pedal is marked “L” or “R.” The left pedal has a reverse thread—turn counter-clockwise to tighten.
4. Mount the Handlebar
-
Feed the brake & throttle wires through the stem, align at your rider’s shoulder width, then clamp using the four supplied bolts.
5. Add the Front Fender
Match the pre-drilled holes on the fork crown; hand-start screws to prevent cross-threading, then snug with the 4 mm Allen.
6. Snap-on Fuel-Tank Shell & Connect Lighting
The magnetic tank hides wire leads for the headlight and RGB side lamps—press until you hear both magnets click.
7. Re-connect Battery & First Power-Up
Join the yellow bullet plug, press the red power button on the right bar and verify the LED dash animates. Scroll through the three speed modes to ensure the hall sensor reads correctly.
8. Optional: Training Wheels
If your rider is still learning balance:
-
Lay the bike on its left side.
-
Loosen—but don’t remove—the rear-axle nut.
-
Slide the bracket on, refit the nut, attach wheel & lock-nut, then repeat other side.
-
Stand the bike; wheels should just touch the floor with a slight lean.

First-Ride Checklist
| Check | Why it matters |
|---|---|
| Tire pressure 25–28 psi | Better shock absorption & range |
| Brake lever travel < 1 cm | Proper pad bite |
| Throttle return spring | Prevents runaway |
| All bolts re-torqued after 15 min ride | Settling of new threads |
Put on a certified kids’ helmet, elbow & knee pads—top speed is 10 mph (16 km/h).
Customisation & App Perks (Plus / APP Models)
-
Bluetooth speaker & engine sound keep kids engaged without external gadgets.
-
Fog-mist unit slides under the tank; refill with purified water only.
-
The Challenger 12 Plus with APP allows parents to geo-fence speed and trigger lights from a smartphone.
Maintenance Snapshot
-
Wipe plastics with a dry cloth—never hose the electronics.
-
Tighten every visible fastener monthly; vibration loosens hardware quicker on turf or gravel.
-
Store indoors; the lithium pack is splash-resistant (IP6) but not submersible.
