It is always good to know what kind of motor you are getting on your ebike in order to see what type of motor you feel suits you best. The most common motors on ebikes are geared hub, direct drive motor and mid-drive motors. We are here to let you know the difference between all in order to make your ebike purchasing experience more fun. In order to understand the motor of these ebikes we need to start with taking a look at the history of the ebike motors and all the functionalities of the motor.


History of E-bike Motors

With the day and era we live in nowadays technology has taken up our entire lives. It was only a matter of time until humans made something electrical to propel bicycles considering bicycles have been around forever. The first known bicycle to propel forward without the use of pedaling is known for its hand-lever system which then inspired the idea of inventing the first ebike. The very first ebike is said to have been with a rear mounted hub motor, this was in 1895. From then forward came the idea of having mid-drive motor. With this design the battery was placed in the middle of the bicycle where from there it would be powered by the mid-mounted motor.


How The Motor Works

An electric bike motor works by turning electrical energy into mechanical energy. Modern ebikes use brushless motors what this means is that the motor does not require brushes to make the motor flow. The way that the motor does this is by using magnets and electromagnets that turn electrical energy into mechanical energy. If you were to open a motor you would see what looks like a bunch of wires and magnets.


Different Types of Motors

As mentioned above, there is more than one motor that we see on ebikes. We have the mid-drive motor, direct drive hub motors and geared hub motors. The mid-drive motor is located by the ebikes crank. As always there is always pros and cons to having a mid drive motor.

  • Pros to having a mid drive motor: Low end torque, Highest peak performance, Gear ratio, Makes it easier to climb hills for longer, Smaller than a hub motor, the bike works around the rider, best weight distribution.
  • Cons to having a mid drive motor: Usually requires more expensive maintenance, A Lot of stress on the chain,

Direct drive motors

  • Pros to having a direct drive motor: Few components making it very durable, more efficient in longer trips,
  • Cons to having a direct drive motor: Not much of low-end torque, removing rear wheel can be difficult, heavier, pedaling becomes less efficient.

Aventon’s Pace ebike line comes with a geared hub motor. Geared hub motors are usually more popular in ebikes due to how durable ebikes are with geared hub motors. With a geared hub motor you will be able to take on more bumpy trails as well as inclines. Ebikes with geared hub motors are more affordable and a great performance fast ebike!

  • Pros to having a geared hub motor: Usually more durable, low end torque, usually more affordable, very little maintenance, lighter and smaller.
  • Cons to having a geared hub motor: because the cable from the hub motor must be attached to the rest of the ebike system, the motor cable must be unplugged to remove the rear wheel, and plugged back in afterwards.

Which Motor Is Better?

It is not a matter of which motor is better, but which motor you feel suits you best. All of them are different and unique in their own way. For example, if one is going to be using the ebike to commute to work and in pavement you would consider purchasing an ebike with a direct drive motor. However, if you want to use your ebike while mountain biking it is likely you wouldn't want to a direct drive motor.
