Hub motors also help reduce other bike maintenance tasks compared to mid-drive motors. As long as they don’t rust out or wear down their bearings, they can pretty much last forever. Gearless hub motors, on the other hand, have zero moving parts aside from their bearings, so there is basically nothing to wear out. Over time, a tooth can break off and the reinforced nylon gears will eventually strip. Geared hub motors usually have just one point of weakness: the gears. There are two types of hub motors: geared hub motors which have internal planetary gears to reduce the speed of a higher RPM motor, and gearless hub motors, which have no gearing and directly connect the lower RPM motor stator’s axle to the bike. That enclosed system also means there is a lot less to fail. They are an entirely independent drive system that retain all of their components inside the motor casing, leaving nothing for you to mess with or maintain. One of the biggest advantages of hub motors is that they require little or no maintenance.
Mid-drive motors, which house the motor closer to the center of the bicycle and transfer the motor’s power to the rear wheel via the bicycle’s chain drive, have become much more common over the last 2-3 years, and are cutting significantly into the hub motor’s lead as the king of the e-bike motors.īoth have a number of unique advantages and disadvantages, so choosing the right motor for you will largely depend on your requirements and which advantages seem more useful to your needs. Hub motors, which place the electric motor in the center of a bicycle wheel, are certainly the most common form of electric bicycle motors. Which one is best for your needs? Read on to learn more and find out! The two most common electric motor styles used in today’s electric bicycles are hub motors and mid-drive motors. Electric bicycles are becoming increasingly popular forms of two-wheeled electric transportation for both commuting and pleasure riding.
