The Kugoo G2 Pro (and its close relative the G-Booster) is a powerful, comfortable scooter built for longer and rougher rides. As with any scooter that gets used hard, a few faults tend to appear over time. The good news is that most are well understood and fixable, usually with a single replacement part rather than a new scooter.
This guide covers the most common Kugoo G2 Pro problems, what typically causes each, and how to fix it. Jump to whichever section matches your symptom.
1. Kugoo G2 Pro won't turn on
A completely unresponsive G2 Pro is usually a power or battery issue rather than a serious fault.
Quick checks first: make sure it's charged, hold the power button properly, and check the battery connector hasn't worked loose — connectors can vibrate slightly loose on rougher rides.
If it still won't power on: the usual suspects are a failing battery or a faulty controller. If range had been dropping before it died, suspect the battery; if it cut out suddenly and never returned, suspect the controller. You'll find batteries and controllers for the G2 Pro in our range. For a full walkthrough, see our guide on what to do when an e-scooter won't turn on.
2. Won't charge or loses charge quickly
If the G2 Pro powers on but won't charge — or range has dropped noticeably — there are two likely causes.
The charger: test this first, as it's the cheaper fix. Plug the charger into the wall alone and check its indicator light. No light, or a light that never changes when connected, points to a failed charger. A replacement charger costs far less than a battery.
The battery: if the charger is fine but range is poor, or it charges to full almost instantly, the battery is likely worn. After a couple of years of charge cycles a replacement is the normal fix. Browse replacement batteries here.
3. Loss of power or cutting out
If your G2 Pro loses power, cuts out, or struggles where it used to pull — especially on hills or off-road — the cause is usually one of these:
- Battery: a worn battery can't deliver power under load, so cut-outs appear on hills or hard acceleration.
- Controller: a failing controller causes intermittent power loss or sudden cut-outs.
- Motor: the G2 Pro's high-power motor works hard off-road; a worn hub motor can cause power loss and unusual noises.
Replacement motors and controllers are in our electricals range. Our guides on a failing motor and replacing a controller help you narrow it down.
4. Brake problems
The G2 Pro uses disc brakes front and rear, which take a lot of load on a heavier, faster scooter — so brake wear is common and important to address.
Weak or spongy braking: usually worn brake pads or a cable that needs adjusting or replacing.
Squealing or grinding: often a worn disc or contaminated pads, which should be replaced rather than ridden on.
You'll find brake pads, discs, calipers and cables for the G2 Pro in our brakes collection, and our guide on fixing e-scooter brakes covers the details. Never ride with brakes you don't trust.
5. Flat or worn tyres
The G2 Pro runs large off-road tyres that take a beating. Punctures and worn tread are common. Many owners switch to solid tyres to avoid punctures altogether — just confirm the correct size for your scooter.
Browse replacement tyres here, and our guide on solid vs honeycomb tyres explains the options.
6. Display or dashboard issues
If the G2 Pro's display flickers, stays dark, or behaves erratically, it's commonly water ingress or a loose connection — the dashboard sits exposed on the handlebars. Reseat the connection and let it dry; if it still won't work, a replacement may be needed. See our guide on replacing an e-scooter display, or check our electricals collection.
7. Folding mechanism or kickstand wear
The folding mechanism and kickstand see constant use and can develop play or wear over time. Stem wobble from a worn folding clamp affects handling and should be sorted promptly. Check the clamp and bolts first; if a part is worn, you'll find frame and body parts in our range.
Quick diagnosis summary
- Totally dead → battery or controller
- Won't charge → test the charger first, then the battery
- Cuts out / weak on hills → battery, then controller or motor
- Weak or noisy brakes → pads, cable or disc
- Punctures → consider solid tyres
- Dark or glitchy screen → display, often after water
- Stem wobble → folding clamp / bolts
