Electric bicycles are growing increasingly popular in the world for both recreational and commuter use. And while e-bikes obviously have a cost advantage compared to electric cars, they also have another important advantage: extreme variety. The Bafang Ultra mid-drive electric motor looks much like its competitors.
That larger diameter also increases efficiency, as the relative speed of the magnets passing by the motor coils is faster. The magnets on the Bafang Ultra are also mounted slightly further from the copper coil which keeps them cooler, also increasing efficiency.
Bafang Ultra
The Bafang Ultra is capable of pulling 1,600 W from the battery using only its stock settings. But the motor is so overbuilt that it is commonly modified to pull well over 2,000 W. The torque rating on the Bafang Ultra is also through the roof. At 160 Nm, this motor is far and above any other mid-drive on the market. The best and latest models from other industry leaders are only now reaching 90 Nm. It means the Bafang Ultra packs well over twice the torque of most of its competitors. That translates into wheelie popping, seat-of-the-pants thrill riding that most people have never experienced before on a bicycle.
The Bafang Ultra is capable of providing power up to 28 mph (45 km/h) under stock conditions. With that much power though, many users will be taking this motor to the dirt trails instead of the pavement jungle. Bafang Ultra’s internal controller is also optimized for extremely high power. Most mid-drive motors use 6 MOSFETs, the small internal circuits that control power flow to the motor. But the Bafang Ultra doubles the standard with 12 MOSFETs. The Bafang Ultra uses triple gear reduction inside the motor, unlike the double reduction found in most competitors. The gears are helical cut, which helps reduce noise.
