This is what Electricbikereview review said in their review.
"DOST Bikes has outfitted the Drop with a mid-drive 750W Bafang motor with 1000W of peak power and 120Nm of torque. This hearty motor is mounted low and centered on the bike. The motor relies on a 24 magnet cadence sensor to provide just the right amount of assist and also connects to a Bafang mid-motor gear sensor that shuts off motor power when you shift gears. This reduces torque on your drivetrain which can put tension on the chain or even bend/chip the teeth on the rear cassette. The combination of the cadence sensor, gear sensor and 9 gear system makes riding the Drop feel very smooth and fluid. The motor system has been well-engineered to provide seamless power that is gentle on the drivetrain."
