An electric bike, also known as an e-bike, relies on a battery to provide power to the electric motor, which assists the rider in pedaling the bike. There are several reasons why you can’t ride an e-bike without a battery:

1. Power source: The electric motor on an e-bike is powered by a battery, which is an essential component of the bike. Without a battery, there is no source of power for the motor, making it impossible to ride the e-bike.
2. No electrical assistance: An e-bike provides electrical assistance to the rider, which helps to make pedaling easier and to cover greater distances with less effort. Without a battery, the electric motor cannot provide this assistance, making it more difficult to ride the bike.
3. Safety concerns: E-bikes are designed with a battery and electric motor to provide added stability and control while riding. Without a battery, the bike may become unstable and difficult to control, which can pose a safety hazard to the rider.

In conclusion, an e-bike requires a battery to function properly and to provide a safe and efficient riding experience.
