A powered e-bike display with a zero speed reading usually points to a missing wheel-speed signal. Follow these safe checks for the magnet, sensor, wiring, settings, and error codes.
When your e-bike battery percentage jumps up and down, it can be difficult to know how much riding range you actually have left. Your display might show 65%, fall to 48% while climbing a hill, and then rise again after you stop. In other cases, one or two battery bars may disappear quickly even though…
You begin pedaling, but instead of the motor responding immediately, nothing happens for a moment. Then the pedal assist suddenly turns on – sometimes with a gentle push and sometimes with an unexpected surge. A delayed e-bike pedal assist response does not always mean something is broken. Many electric bikes with cadence sensors are designed…
If your e-bike battery charges but has no power, it can be confusing because the charger light may turn green, the battery indicator may look full, and the bike still will not turn on or move. I have had enough e-bike electrical issues come up while working on Electric Bike Explorer to know that this…
When an e-bike suddenly stops working, cuts out under load, or powers on but will not move, it is easy to assume the worst. The problem might be the e-bike battery, the controller, or the motor, but it could also be something much simpler like a loose connector, stuck brake sensor, bad display connection, damaged…
If your e-bike motor makes a grinding noise, it can be a little unsettling.

Use the interactive E-Bike Error Code Finder below to look up your error code and learn the most common causes, along…
Electrical problems can be some of the most frustrating issues an e-bike owner faces. Your bike might randomly lose power, refuse to turn on, cut out while riding, or display error codes that seem to disappear as quickly as they appear. When that happens, it’s easy to assume you’ve got a failing battery, controller, or…
Few things are more frustrating than plugging in your e-bike after a ride only to discover the battery isn’t charging. Whether your charger light stays green, the battery won’t respond at all, or your electric bike suddenly stopped charging after sitting in storage, it’s easy to assume the battery has failed. Fortunately, that isn’t always…
If your e-bike shuts off going uphill, you’re not alone.

The good news is that most e-bike clicking sounds are not caused by major motor failures. In many cases, the culprit is something much simpler, such…
If your e-bike suddenly feels like you’re pedaling through mud when the motor turns off, you’re probably wondering if something broke. In many cases, nothing is wrong at all.
