Mounting Options for Controller
The BAC855 controller can be mounted below the bottom bracket
(pre-assembled by default) or mounted elsewhere on the bicycle
frame at the user's discretion using the controller extension wire
that can be selected upon purchase or purchased separately from
the CYC online store or an authorized dealer.

between the mounting plates.
Adjusting the Width of Bottom Bracket
In order for the X1 Stealth to fit on various different widths of
bottom brackets, there are several spacers that come with the kit.
These spacers are designed to provide the bottom brackets with
necessary spacing between the X1 Stealth brackets.
The preferred mounting set-ups are shown on the next page for
68mm and 73mm bottom brackets. Note that the spacers can be
adjusted to accommodate different chain lines as needed.
Before mounting the motor body to your bike frame, the existing
crank system and bottom bracket must be removed.

05 QUICK START
STEP 1
Ensure that all wires are properly connected & that your system can
switch on by long 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 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.
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. Kindly see your display’s user
manual for instructions.
Ensure that you test the PAS & throttle in Assist
Level 0 as to prevent your bike from thrusting
forward.
