An electric bike is known as an electric-assisted bicycle, or e-bike or pedelec in foreign countries.
They are different from the electric bikes that we normally see, which rely solely on electricity, and are also different from purely human powered bikes, which have an electric drive, but are still mainly driven by human pedaling.
Only when pedalling actively does the electric bicycle provide additional auxiliary power to the bike via the motor drive system, thus reducing the pedalling pressure on the rider and making the ride easier and less strenuous. The electric bikes are differentiated by application or power level, with a variety of power levels to meet the multiple needs of different users.
A representative model is the electric bike Pathfinder 1.0
