Segway-Ninebot scooter troubleshooting: flats, error codes and common fixes

This page covers common problems on Segway-Ninebot kick scooters, including the Max series (G30, G30P, G30LP and newer G models), plus the F, E, P and ES series. Tires, brakes and displays differ a lot between models, so always check what you find here against the manual for your exact scooter.

Before you start

• Find your model number on the label on the side of the deck. The G30LP user manual says your serial number also shows in the Segway-Ninebot app under More Settings, then Basic Information.
• Get manuals and official repair videos from Segway's support pages.
• Power off and unplug the charger before any check.
• Segway's manuals say the battery has no user serviceable parts. Never open the battery or try to repair it.

Common problems and what to check

Scooter won't turn on

1. Charge it fully with the original Segway charger. The G30LP manual says the charger light turns from red to green when charging is done.
2. Make sure the charge port is dry. Segway says not to charge if the port, cable or outlet is wet.
3. Think about how long it sat. The ES3 Plus manual says a full battery holds charge for roughly 120 to 180 days in standby, but a low battery only 30 to 60 days. A deeply drained pack may need a pro.
4. A new scooter that crawls along is often not activated yet. The G30LP manual says it stays at very low speed until you activate it in the Segway-Ninebot app.

Won't charge

• Use only the Segway charger. The G30LP manual also recommends a surge protector.
• Keep riding, charging and storage inside the temperature limits in your manual.

Wrench icon or error code on the dashboard

• The G30LP manual says the wrench icon means the scooter found a fault, and the speedometer shows a code. Run a diagnosis in the Segway-Ninebot app and contact your dealer.
• Codes 14 and 15 often just mean the throttle or brake was held while powering on. Let go and restart.
• Stop riding right away if the scooter makes abnormal sounds or alarms, as the G30LP manual says.

Flat tire or slow leak

Flats are the most common scooter repair. Wipe the scooter with a damp cloth rather than a hose, which Segway's manuals warn against.

• The G30LP manual lists tubeless 60/70-6.5 tires and says to inflate them to 32 to 37 psi, both tires equal. Other models use different tires and pressures, so check yours.
• The E2 Plus II manual describes 8.1 inch inner hollow shock absorbing tires, which are not inflated.
• Check pressure often. Low pressure wears tires fast and makes flats more likely.
• The G30LP manual says tires should be mounted by a professional, since a badly fitted tire can make the scooter unstable. Segway's videos below show the job.

Brakes feel weak, noisy or rub

• Spin the rear wheel by hand. The E2 Plus II manual says it should turn freely and the brake should stop it.
• The G30LP manual says to leave brake work to an authorized repairer. Segway does publish adjustment videos for some series, like the F series disc brake video below.
• More on brakes.

Stem wobble or folding feels loose

• Before every ride, check for loose fasteners and damaged parts, as Segway's manuals advise.
• If the stem folds, wobbles or the latch feels wrong, stop riding. On a Max G30P or G30LP, check the recall below first.

Recalls

• Max G30P and Max G30LP: CPSC announced a recall on March 20, 2025 for a folding mechanism that can fail. Owners should stop riding and request the free maintenance kit. The CPSC notice explains how to confirm your model.
• P100S: CPSC lists a recall for P100S scooters made in 2023 for a front fork that can break. The CPSC notice explains how to read the date code in your serial number. Repairs are free.
• Request either fix through Segway's recall form.

Error codes

These meanings come from the E2 Plus II product manual. Codes and meanings differ by model and dashboard, so your own manual and the app have the final word.

• 10: Bluetooth communication fault. Check the dashboard cable or contact service.
• 14: throttle signal fault. Check that the throttle was not pressed at power on.
• 15: brake signal fault. Check that the brake was not squeezed at power on.
• 35: serial number still set to the default.
• 39: battery temperature fault.
• 40: controller temperature too high. Contact service.
• 41: motor temperature fault.
• 50: motor phase loss.
• 52: motor stalled. Check whether the scooter is overloaded.

For most other codes, the manual says to contact Segway after sales or an authorized dealer.
