What is an electric bike battery replacement?

  • Reduced range: If your bike’s range has significantly decreased, it may be a sign that the battery is no longer holding its charge.
  • Slower speeds: If you’ve noticed that your bike’s top speed has reduced, it may be because the battery is no longer providing enough power to the motor.
