Learn how to tune and dial in your scooter for the best possible ride — a great watch for any rider looking to get more out of their setup.

A rattling noise or loose bar is one of the most common scooter issues we hear about — and the good news is it's almost always a quick fix. Follow the step-by-step diagrams below to sort it out at home.

Is your scooter making a rattling noise? Bar a bit loose? Follow this quick and easy diagram to rectify the problem.

Your scooter maintenance should involve removing the headset to clean the grime build up which can affect a smooth ride. Sometimes it helps to check that the bearings have not come loose through riding — depending on how often the scooter is used, we suggest checks every 3–6 months.

Follow our step by step guide on how to remove, re-install or replace your headset.

If your bike isn't responding, work through these steps before getting in touch with us.

1. Ensure the bike power is turned on
In addition to the speed switch, there is a silver push-button on the right side of the bike above the foot peg. Press this in — you may need to hold it for a second to activate the power. You will see the lights on the throttle illuminate.

2. Activate the safety brake function
Once the bike is powered on, squeeze the brake lever to activate the motor. Use your left hand to squeeze the brake, release, then slowly turn the throttle. If the bike is left alone for a period of time the motor power will disengage — simply repeat this process.

3. Check the battery power status
Battery voltage is displayed on the throttle. When the bike is turned on the 24V light will illuminate. If fully charged, the FULL light will also be on. As the charge drops, the LOW light will indicate it's time to charge. Initial charge may take up to 12 hours — subsequent top-up charges take between 4 and 7 hours.

Many customers experience issues with their bike not operating correctly because the battery has not been fully charged. Please follow these instructions carefully.

Why a full 24-hour charge is required
The included AC wall charger has an indicator light that turns green when the battery reaches a partial voltage threshold — this does not mean the battery is fully charged. The bike's Battery Management System (BMS) requires a minimum of 24 hours of uninterrupted charging when first charging the bike (and after long storage periods) to balance the battery cells. If the battery is not charged for the full 24 hours it may remain in a low-voltage state, and the bike's built-in safety feature will prevent it from powering on.

Step-by-step charging instructions

• Turn the bike's power switch OFF
• Plug the charger into a standard household outlet
• Connect the charger to the charging port on the bike securely
• Leave the charger connected for a minimum of 24 continuous hours — even if the indicator light turns green
• After 24 hours, disconnect the charger from the bike and outlet

Tip: Avoid unplugging the charger early even if the light is green. The BMS needs the full charge cycle to balance cells and enable proper operation.

Troubleshooting charging issues
The bike won't power on after charging:

• Was the bike charged for the full 24 hours? If no, reconnect the charger and complete the full charge. If yes, unplug and replug the charger to reset, then attempt another full charge.

Charger light turns green quickly:

• This is normal — it means the voltage threshold was reached, not that the battery is fully charged. Continue charging for the full 24 hours.

Ongoing charging best practices

• After the initial 24-hour charge, standard charging time is typically 8–12 hours when the battery is low
• Always charge the battery immediately after riding to prevent it dropping into a low-voltage state
• Do not allow the battery to sit unused for long periods without charging — recharge at least once a month during storage

Why the low-voltage safety feature matters
The BMS is designed to protect your battery from damage caused by being too low. If the voltage drops too far, the bike will not operate until the battery has been fully charged and balanced. Completing the full 24-hour charge ensures the bike is ready for safe use.

Still having trouble after completing the full 24-hour charge? Confirm all charger connections are secure and the charger is working, and check that the bike's power switch is turned ON. If the bike still does not power on, contact us and we'll help sort it out.
