Ebike can't turn on – Velowave Bikes Help Center

If your electric bike happens to encounter difficulty turning on, this guide will assist you in troubleshooting the issue, ensuring a swift return to enjoying Velowave rides.

Overview

Begin by assessing the battery's functionality, followed by inspecting the connections to identify the root cause of the issue.

Assesse the battery

1. Verify the charge levels of the battery

Press and hold the battery button, as the figure below. Pressing the battery button will show you the charge level (Green indicates sufficient battery power, yellow indicates moderate battery power, and red indicates low battery power).

If there is no response from the battery at all (no charge level indicators illuminate), several potential causes could be at play. It's possible that your battery needs charging (refer to the next bullet point).
If the battery gauge indicates no or low charge, recharge the battery and attempt to turn on the bike after it has been fully charged. Refer to the Owner’s Manual for instructions on how to charge the battery. If charging is unsuccessful, document the charging process in a video, including the lights on the charger and battery, and reach out to Customer Support for assistance.
If the light is green or the battery is fully charged, proceed with the troubleshooting process.

Measure using a multimeter. If you have a multimeter, you can measure the battery's output voltage as shown in the diagram. The normal output voltage should be between 46V and 58V.

If the measured voltage is below or above the normal range, take a photo and contact our customer support for further assistance.

2. Examine the battery and the terminals on the battery mount

Examine the battery and the terminals on the battery mount. Look for any dirt, damage, or moisture accumulation at the bottom of the battery and on the battery mount.

If everything appears undamaged but damp, let the battery and battery mount/terminals air dry thoroughly before reinstalling the battery and trying to turn on the bike.
If the connector's interior is damaged or dirty, do not try to repair the damage or clean the contacts. Capture a photo and reach out to Product Support for further assistance.
If the connector appears normal, take a photo for documentation purposes and proceed with the troubleshooting process.

Reinsert the battery and switch the bike ON.

If the bike does NOT power ON, proceed to check the connector.
If the bike powers ON, proceed to fully test and enjoy your ride!

Inspect individual connectors

Several key connectors can prevent the bike from turning on if they're loose, misaligned, or damaged.

Display connector

1. Locate the Display connector.

2. Examine the interior of the connectors.

If the interior of a connector appears damaged, dirty, or wet, the component may require replacement. Capture a photo and reach out to Customer Support for assistance.
If the interior of the connector appears to be in good condition, align the internal notch and pins with the external arrows, and press them together without twisting to reconnect.

3. Reinsert the battery and switch the bike ON.

If the bike does NOT turn ON, switch off the bike, detach the battery, and discharge any remaining power. We'll repeat this process with the remaining connectors.
If the bike powers ON, proceed to fully test and enjoy your ride!
