ASI BAC855 Advanced Motor Controller

This controller is commonly utilized for upgrades in systems like the BBSHD, Cyclone Mid Drive Motor Kit, Stealth Enduro Style EBikes, and various others. It's equipped to accommodate a torque sensor and employs FOC (Field Oriented Control) in its control algorithm, ensuring remarkably smooth and highly efficient performance. Despite its compact size, it boasts impressive power capabilities. These controllers offer an exceptionally smooth ride!

Please note: These controllers require setup for the motor by our team. Simply sending you a controller won't suffice; it needs to be programmed for your specific motor. This can be done remotely, but please reach out to us before making a purchase.

While these controllers are ideal for custom projects, if you're seeking the most budget-friendly option to get your EBike up and running, these are considered a premium product.
