There may be a couple reasons on why your bike display may not turn on.
In the majority of cases, there is a loose connection between the display and the controller (located within the frame of the bike). To diagnose this, please follow the wire coming out from behind the display into the bundle of wires. If there is a plastic cover on this bundle, please unravel it until you see a quick disconnect (refer to image 1 attached). If the wire is disconnected, reconnect them by lining up the two arrow signs, and connecting the two wires.

Your electric bike may also not turn on because the battery is not charged. The only accurate way to test to see if the battery has power remaining is to take a voltmeter or amp multimeter and connecting the positive and negative (refer to image 2). If the reading shows between 42 to 54, you have a healthy battery, and it is not the primary reason why your bike is not turning on.

In rare cases, your bike may not turn on due to a faulty controller or display. In these cases, please contact us at email@example.com
