ASI BAC855 Advanced Motor Controller

This is a common controller used for upgrades on systems such as the BBSHD, Cyclone Mid Drive Motor Kit, Stealth Enduro Style EBikes, and many others. It has the ability to run a torque sensor, uses FOC (Field Oriented Control) for its control algorithm which is super smooth and highly efficient. And it has a very high power capability for its size. These controllers are extremely smooth!

NOTE: These controllers must be setup for the motor by us. We can not just send you a controller, it will need to be programmed for your motor. This can be remotely, but please contact us before purchase.

These are awesome for custom projects but if you are looking for the lowest priced controller to get your EBike going, these are definitely a premium product.
