INSTALLATION GUIDE
FUSE

FIT THE BRACKET TO THE BARS
Use the appropriate shims:
• Pre-installed – 25.4mm Bars
• Slim Shim – 31.6mm Bars
• No Shim – 35mm Bars
The bracket should be tted to the bars on the drive side (right-hand side when in the saddle) of
the stem and pointed down approx. 45 degrees, to ensure the cables can route below the stem
without interference.
Tighten bolts to 4Nm.
Attach remote near to either grip with appropriate O-ring.

FIT THE MOTOR SPECIFIC CABLE TO THE BIKE (BOSCH, BROSE AND YAMAHA)
Route the power cable to the motor. Due to the extensive variety of bikes, routing and designs
this is a case-by-case choice, if you need advice please contact your local supplier or the bike
manufacturer.
The connectors are specic to the outlet on the bike and take very little effort to engage. If you
require force it is probably wrong.
Cut wires to length leaving enough to work with.
Strip outer casing to show 30mm cable. DO NOT STRIP INNER WIRES. The cables need the outer
intact for a successful waterproof seal from the connector.
Fully insert similar coloured wires from light cable and motor cables into the same butt crimp.
The cables must touch the ‘back’ of the crimp.
Use pliers to fully compress the button into the housing. This will strip and connect the wires, and
the silica gel waterproofs the connection.
PLEASE TAKE YOUR E-BIKE AND EXPOSURE E-BIKE LIGHT TO AN AUTHORISED
DEALER FOR YOUR MOTOR MANUFACTURER FOR INSTALLATION.

WARNING! IF THE NEXT STEPS ARE NOT PERFORMED CORRECTLY YOU MAY
DAMAGE YOUR BIKE, LIGHT; OR BOTH.
The lights will draw as much power as they require to run the LEDs at their brightest. This means
that if the light can draw more power than is available from the bike it may damage the bike motor.
Ensure to match the current setting of the light to the power output of the bike.
The light will automatically detect the voltage of the motor you’re plugging it in to. To select the
correct power setting, hold the button down for 20 seconds (the light will emit a rapid set of
ashes) then follow the tables below:
When the light is off a single button press will indicate the active current limit by the button colour.
