CYC MOTOR (BAC) MOBILE APP FOR ASI BAC CONTROLLERSThe CYC MOTOR (BAC) app is the X1 PRO and the X1 Stealth's navigation system. This is where you will customize your experience & monitor your performance.
The app is connected to your controller via Bluetooth & will allow you to set up your system & change parameters according to your preference.
The CYC MOTOR (BAC) app allows you to do multiple things:
If you have a BAC855 or BAC2000 controller for your X1 PRO or X1 Stealth, then this app is needed to set up a few things to get started such as your regions legal limits, your battery voltage, & wheel diameter. You will also need the app to clear any warnings or errors that may occur.

The CYC X1 Stealth mid-drive motor is a high-end/high-performance ebike conversion system that is the creation of CYC Motors in Hong Kong. These guys know what they are doing. They created this bad boy as the stealthy baby brother of the X1 Pro but it is still one of the most powerful motors available.
This motor preserves a perfect chain-line on any bike and tucks up high off the ground even on modern mountain bikes with a curved downtube. With its torque sensing and cadence sensing bottom bracket, it delivers power at the cadence you choose and senses when you crank up your effort and delivers more power on demand.
This motor is very versatile, fitting 95% of frame types including carbon frames. It can be set up as a class 1, class 2, or class 3 ebike from 350 to 750 watts. Off-rode modes go from 750-2,000 watts (depending on battery).
It comes with everything you need except the battery and we have those in 52v and 72v at 50 amps and from 300 watt hours to over 1000 watt hours.
Included:
For lights powered from the main battery, you should consider the Roxim Light Set. It can take voltages from 6v-90v and can be wired directly into the main battery. A single switch on the headlight turns the headlight and taillight on/off.
For a great 1x drivetrain the ebike rated Box Two and Box Three drivetrains are both durable and affordable. With all of the power this motor can deliver, you will still wear out the higher (smaller) gears on the rear sprocket. Fortunately, Electrify Bike Co. has arranged with Box to sell these as a set of 4 sprockets for just $20 so you can just change them out when they start to slip.
Note: Stealth motors are shipping! We are working through our backlog and new orders are now only 3-4 weeks to ship. Thank you for your patience.
