Quick start guide
After unboxing and installing your X1 Pro or X1 Stealth, there are a few things you need to
set up and check.
STEP 1
Ensure that all wires are properly connected and that your system can switch on by pressing
the display’s power button. Check that the display shows your battery voltage and 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 and level not display refer to step 3.
STEP 2
Ensure that your pedal assist and throttle are working correctly. To test this,
connect to the CYC Motor (BAC) mobile app and change to Assist Level 0 on
your display. You can test the PAS by looking at the app’s dashboard and
turning the crank set. If your Average Pedal RPM reading changes, then your
PAS is working. To test the throttle, open your throttle and check that your
Throttle In voltage changes. Ensure that you test the PAS and throttle in Assist
Level 0 as to not make the bike thrust forward.
