Bafang Mid-Drive Motor: Natural Power That Feels Like an Extension of Your Legs

At the heart of the Persei R7 is a Bafang 250W mid-drive motor capable of producing up to 80Nm of torque. It delivers smooth and responsive pedal assistance exactly when you need it, making steep gravel climbs feel remarkably manageable.

Unlike traditional hub-drive systems, the mid-drive motor applies power directly through the drivetrain, creating a more natural riding sensation and significantly improving climbing traction and efficiency.
