Hub Motors: Hub motors are located in the hub of the front or rear wheel, providing direct drive to the wheel. They are simple and easy to install, and come in two types: direct-drive and geared. Direct-drive hub motors are quieter and more efficient, but heavier, while geared hub motors are lighter and offer more top-end speed, but are less efficient.

Mid-Drive Motors: Mid-drive motors are located in the middle of the bike, near the bottom bracket, and use the bike’s chain to transmit power to the rear wheel. This type of motor provides better traction and control, especially on challenging terrain, as it works in harmony with the gears of the bike. Mid-drive motors are also more efficient than hub motors as they can use the bike’s gears to optimize power delivery.
