Operating Notice
RIGHT-HAND and LEFT-HAND sides are determined by the bike handle; Right-hand corresponds to
the right handle.
Mounting Options for Controller
The CYC X6 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 controller extension wires
that can be selected upon purchase or bought separately from the CYC online store or an
authorized dealer.
NOTE: The controller comes preassembled at the bottom bracket between the mounting plates.
Adjusting the Width of the Bottom Bracket
In order for the CYC kit 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 motor brackets.
Please note that the spacers can be adjusted to accommodate different chainlines as needed.
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 you begin, ensure that you have removed the original crank set and bottom bracket from
your frame. This includes any bearings and/or cups that might have been fitted previously. To
install your CYC kit, you will need a clean bottom bracket shell on your frame.
