Motor Power: Bafang Ultra (M620) vs. Bafang M600
On average, the Bafang Ultra (M620) motor can provide more power than the Bafang M600 motor. Bafang Ultra (M620) can provide up to 1000W of power, while the Bafang M600 can provide up to 500W of power.
The motor power (expressed in watts) is a measure of the work being delivered in a specific period. Technically, the higher the watts, the more work that is being done.
Since Bafang Ultra (M620) motor can provide higher power than the Bafang M600 motor, it can deliver more work than Bafang M600 within a specific amount of time. In addition, with its higher motor power and torque, Bafang Ultra (M620) can help your electric bike accelerate more quickly.
Therefore, if 1000 watts is needed, it is highly advisable to choose the Bafang Ultra (M620) motor.
Weight: Bafang Ultra (M620) vs. Bafang M600
As a general rule, the Bafang Ultra (M620) motor is heavier than the Bafang M600 motor by 3.1 pounds (1.4 kg). The Bafang Ultra (M620) motor has an estimated weight of 11.7 lbs (5.3 kg), whereas the Bafang M600 motor weighs 8.6 lbs (3.9 kg).
The weight of the electric bike motor will increase the entire weight of your electric bike. Though the Bafang Ultra (M620) motor is heavier by 3.1 pounds (1.4 kg), this weight does not significantly affect the overall performance of the e-bike itself.
Additionally, pedaling won’t become more tiresome even with a heavier weight because the M620 motor provides the necessary assistance to make the weight difference negligible.

Primary Usage: Bafang Ultra (M620) vs. Bafang M600
As a whole, the Bafang Ultra (M620) motor is primarily used and designed for e-cargo bikes, e-tandems, and high-end e-MTBs. On the other hand, the Bafang M600 motor is designed for high-performance e-MTBs.
With its higher torque and power output, the Bafang Ultra (M620) motor is best for electric bikes carrying heavy loads, such as electric cargo and electric tandem bikes. If you carry a lot of weight, you need a lot of power from your motor to propel your electric bike, especially when going up steep inclines. The Bafang Ultra (M620) motor will provide the power and support you need to accelerate.
The Bafang M600 motor is best used in high-performance electric mountain bikes because of its triple-sensor system. This triple-sensor system is composed of one torque sensor and two-speed sensors. These sensors will react quickly to your pedal-power input. Hence, it provides excellent support.
Location: Bafang Ultra (M620) vs. Bafang M600
As a general rule, Bafang Ultra (M620) and Bafang M600 motors are placed in the same location. These motors are positioned near the middle of your electric bike. Mid-drive motors are highly efficient for riding on rough terrains and up hills.
Since Bafang Ultra (M620) and Bafang M600 are both mid-drive motors. They provide excellent weight distribution on your electric bike. Since there is more even weight distribution, your ride will be more smooth and comfortable, even at greater speeds. In addition, mid-drive motors work with the electric bike gears, which provide impressive power output to your electric bike.
