If you're technically inclined and don't mind getting your hands dirty, you can retrofit almost any bike with a hub motor or mid-drive system.
The type of battery you should use with your hub motor depends on factors such as voltage, capacity, and chemistry. Lithium-ion batteries are commonly used for their high energy density and long lifespan.
A mid drive motor powers the cranks and sends force through the drivetrain in the same way your own legs would move it with added assistance. The second is a hub drive motor, which is located within the rear or front wheel of the bike and powers the motion of the wheel itself.
The brushless wheel hub motor, which is most widely used in electric cycle motors all over the world, is now gradually shifting its influence to large electric vehicles such as electric cars, electric buses and electric trucks.
