The Bafang Ultra Gear Shift Sensor is an essential component for maintaining optimal drivetrain performance on your mid-drive e-bike. This replacement sensor detects gear changes and communicates with your Bafang Ultra motor to prevent power delivery during shifting, protecting your chain and cassette from damage. Designed for seamless integration with Bafang Ultra systems, it ensures smooth, efficient gear transitions while extending the lifespan of your drivetrain components. A critical upgrade for riders seeking reliable, precision-engineered performance. *Takeoff parts are parts which have been removed from brand-new, never ridden bikes. These parts may have some minor scuffs or fitment marks but are identical in performance and specifications to the brand-new version.
