Theoretically, hub in motor has advantages in design, but when it comes to actual riding, countless external factors can affect the hub in motor's functioning and performance efficiency, leading to many misunderstandings and "myths" about hub in motors. Let's tackle them one by one.
In some "stereotypes," mid-drive motors have long been synonymous with high-tech. A long time ago, when you walked into a bike shop, the first things you saw were cheaper e-bikes with affordable hub in motors, which didn't have much"high-end"new technology.
However, in terms of technology, modern new hub in motors are not necessarily worse than mid-drive motors. With the high-tech systems and auxiliary devices often used in mid-drive motor systems, hub in motors can also provide a perfect riding experience.
It can be said responsibly that the huge gap between mid-drive motors and hub in motors is closing. This marks the end of an era. The misconception that hub in motors are technically inferior to mid-drive motors should be erased from our minds.
This view is too one-sided. Both hub in motors and mid-drive motors have products corresponding to low, mid, and high-end markets. However, the current mainstream view is that hub in motors are usually used in cheap e-bikes, and high-end e-bikes without exception use mid-drive motors.
The current market trend is changing, and the e-bike market is showing a completely different picture. Currently, the price of e-bikes is still very high, and at such high prices, manufacturers have enough cost to purchase any motor system to install on their bikes.
Hub in motors and mid-drive motors have different weight distributions, which is an undeniable fact. For e-bikes, mid-drive motors are installed between the wheels, and their low center of gravity is usually beneficial. When hub in motors are installed, most of the weight shifts to the rear wheel. Of course, only some riders who are very sensitive to weight distribution will notice the difference.
However, if you are not a downhill enthusiast and don't need a super-agile bike, an excellent e-road bike with a hub in motor will bring you a lot of fun.
Overall, the special weight distribution of hub in motors has only a minor impact on the riding feel of the whole bike. What's important is that the weight distribution needs to interact harmoniously with the frame geometry, which is the real test for manufacturers.
Due to the differences in weight and shape, hub in motors are often considered weak, while robust mid-drive motors are synonymous with strong power. Currently, intuitive torque and weight data have become key points for many motor manufacturers' promotions. However, these data themselves are not decisive for the performance of motor systems.
Since hub in motors apply force directly to the wheels without the loss caused by the transmission system, even if the paper data is not as good, it does not mean that the actual output of the hub in motor is weak. An excellent motor system is not just about the data on paper; it also needs to adjust the appropriate torque range according to the actual riding conditions instead of just pursuing the maximum power output.
