The Engineer's Guide to e-bike Drive Systems: Hub Motors vs. Mid-Drive Motors

When it comes to electric bicycles, there are two main types of drive systems: hub motors and mid-drive motors. Both have their own advantages and disadvantages, so it's important to understand the difference between the two before choosing the right one for your needs.

Hub motors are the most common type of electric bike motor. They're usually located in the front or rear wheel, and they provide power to the wheel they're attached to. Hub motors are simple and efficient, but they can be less powerful than mid-drive motors.

Mid-drive motors are located in the middle of the bike, near the bottom bracket. They're more expensive than hub motors, but they offer a number of advantages. Mid-drive motors are more powerful than hub motors, and they also allow you to use the bike's gears to increase or decrease the amount of power you're getting. This can be helpful when climbing hills, for example.

So, which is the best type of motor for you? It really depends on your needs. If you're looking for a simple, efficient, and affordable electric bike, a hub motor is a good option. If you're looking for more power and the ability to use the bike's gears, a mid-drive motor is the way to go.
