Before the Ride

Ensure that the drive unit chain has the proper tension. Incorrect tension could cause jamming of the system and result in injury while riding. Inspect the chain tension regularly.

Ensure that the chains are properly lubricated. Cleaning and lubricating your chain with regular bicycle chain cleaner, is advised regularly.

When connecting a power supply, make sure the power supply is completely connected. Faulty connection could result in a short circuit and damage the controller or batteries.

Inspect all electrical wires and plugs for damage regularly.

Secure all wires properly. Ensure that no loose wires are dangling from the bike that could be jammed into any moving parts.

Before turning on the system, ensure that the throttle can be twisted freely without friction and that the throttle can return to its original position without restriction. This is to prevent any uncontrolled response of the system.

Installation & Use

Do not install anything other than the parts and accessories that came with this drive unit. Doing so could damage the product.

The drive system can be activated and deactivated by holding down the on/off button on the display.

Avoid changing the bike gear (note: this is different from the drive unit’s assist level) while the drive unit is powering the bike. This may lead to excessive wear on the chain and chain rings or other gear related failure.

When changing gear, use human input only. After the gear is changed, you may accelerate again with the throttle or continue using the PAS.

Take off with the appropriate assist level & bike gear.

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.

NOTE: The controller comes pre-assembled at the bottom bracket 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.

*68mm bottom brackets require a 7mm and a 5mm spacer on the left (non-drive side) and a 3mm spacer on the right (drive side) as shown.
*73mm bottom bracket requires a 7mm & 3mm spacer on the left (non-drive side) and no spacer on the right (drive side) as shown.

Installation of 68/73/83mm version

Line up the motor body with your bike at the bottom bracket. For a 68mm bottom bracket width, place the 3mm spacer between the mounting brackets & the bottom bracket shell as needed & shown on previous page. For 73mm & 83mm bottom bracket widths, no spacer is needed.
Thread in the right (drive side) bottom bracket cup through the hole on the right mounting plate & into the bike’s bottom bracket shell. Note the thread direction is anti-clockwise.
Thread in the left (non-drive side) bottom bracket cup through the hole on the left mounting plate (and spacers for 68mm & 73mm bottom bracket widths) into the bike’s bottom bracket shell. Note the thread direction is clockwise.
Insert the spindle from the right (drive-side) side of the rear mounting bracket hole through to the left side of the rear mounting bracket hole.
Screw on the left (non-drive side) bottom bracket cap.
Remove the right (drive side) bottom bracket cap & the front chain ring cover.
Place the chain over the outer chain ring (note that the bike’s chain ring will be placed on the inner chain ring & hang the chain ring with the chain over the spindle. Push the tensioner down to place the chain over the sprocket.
Slide the chain ring in place (over the spindle), screw on the right (drive side) bottom bracket cap & install the front chain ring cover again as shown.
Install the left & right crank arm and screw on with the crank bolt.

Installation of BB92 version

Line up the motor body with your bike at the bottom bracket.
Insert the right (drive side) bottom bracket cup through the hole on the right mounting plate into the bike’s bottom bracket shell. Use press-fit bottom bracket tool to insert.
If any spacers are needed, place the spacer/s between the bracket & the bottom bracket shell on the left (non-drive side). Insert the left bottom bracket cup through the hole on the left mounting plate into the bike’s bottom bracket shell. Rotate clockwise and tread into drive side bottom bracket cup. Tighten well.
Insert the spindle from the right (drive-side) side of the rear mounting bracket hole through to the left side of the rear mounting bracket hole.
Screw on the left (non-drive side) bottom bracket cap.
Remove the right (drive side) bottom bracket cap & the front chain ring cover.

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.

Ensure that you test the PAS & throttle in Assist Level 0 as to prevent your bike from thrusting 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. Kindly see your display’s user manual for instructions.

MAINTENANCE

You are advised to regularly maintain, clean and check the status of the bike and motor system as dirt will accumulate throughout the rides and additional strain will be taken by the drive train due to the powerful motor system. We recommend that users should inspect the bike and motor condition before and after each ride.

Disconnect all power supplies from the drive unit before starting any work (e.g., inspection, repair of the bike, maintenance work etc.) on the bike, transportation or storage. Unintentional activation of the drive unit could lead to serious damage or injury.

Never reach into the chains, gears or any moving parts while the bike is still in operation.

The drive unit can get quite hot after use, be sure to give it some time to cool down before doing any maintenance.

Store the bike in a cool and dry place, sheltered from direct sunlight and potential rain.

Do not attempt to disassemble or modify the drive unit. The drive unit may only be repaired and maintained by qualified experts and only replaced with original spare parts. This will ensure that the safety/warranty of the drive unit is maintained.

The active moving parts (e.g., chain, gear, speed reducer etc.) should be regularly lubricated to maintain desired performance. In case of any abnormal activity, stop using the drive unit immediately and contact your CYC dealer.

Do not attempt to replace the X1 PRO parts with the parts that have been found at a local bicycle store as the materials used in the drive unit are specifically designed for their purposes.

All bolts, nuts and screws are required to be tightened to the correct torque, if there is anything loose, stay off the bike. Torque specifications for each bolt and nut is provided below.
