Quick start guide
After unboxing & installing your X1 PRO or X1 Stealth, there are a few things you need to set
up.
STEP 1
Ensure that all wires are properly connected & that your system can switch pressing the
display’s power button. Check that the display shows your battery voltage & level. Should
your display briefly show Error 30H upon start-up, this is normal as the system takes a
moment to connect. Should your battery voltage & level not display refer to step 3.
STEP 2
Ensure that your pedal assist & throttle are working correctly. To test this,
connect to the CYC Motor (BAC) mobile app & change to Assist Level 0 on
your display. You can test the PAS by looking at the app’s dashboard &
turning the crank set. If your Average Pedal RPM reading changes, then your
PAS is working. To test the throttle, open your throttle & check that your
Throttle In voltage changes. Ensure that you test the PAS & throttle in Assist
Level 0 as to not make the bike thrust forward.
STEP 3
Set up the correct information on your display. You will need to enter your wheel diameter,
battery voltage (if incorrect), & your preferred number of assist levels.
