INSTALLING THE HUB MOTOR WHEEL
Please refer to FIG 1 on the following page for installing your new Hilltopper HUB MOTOR WHEEL.
Please orient FIG 1 to your installation position. Installation positions include bike upside down with handlebars and seat resting on
the ground, on a bike rack, or standing with the wheels on the ground. FIG 1 image orientation is looking at the front of the bike with
the wheels on the ground.
The best way to orient FIG 1 is to always use the DRIVE SIDE. This is the side with the chain.
STEP 1:
Loosen your brakes and remove your bike’s front wheel.
DISC BRAKES: After removing your wheel, make sure you put a plastic spacer in between the brake pads to keep them
from locking shut. REMOVE THE PLASTIC SPACER BEFORE REINSTALLING YOUR WHEEL.
A.
Remove the disc brake rotor from your wheel.
B.
The HUB MOTOR WHEEL is disc brake compatible.
C.
Align the disc brake rotor with the holes on the MOTOR.
D.
Attach the rotor to the MOTOR using the disc screws provided.
NOTE: Your brake may need some adjusting after installation to avoid rubbing.
STEP 2:
Set your HUB MOTOR WHEEL in place with the MOTOR CABLE on the NON DRIVE SIDE.
Ensure that the bike fork is seated securely on the axle with the fork prongs projecting down
Make sure the wheel can turn properly without rubbing or grinding on the fork or brakes.
NOTE: Remove plastic spacer from disc brakes before setting wheel in place if installed earlier.
STEP 3:
Slide the
TAB WASHER
over the axle on both sides of the MOTOR.
NOTE: Ensure that the MOTOR CABLE is on the NON DRIVE SIDE of the bike and that the
TAB WASHER
is properly installed.
A. The
“TAB”
on the
WASHER
faces inwards towards the MOTOR, and down towards the MOTOR CABLE.
B. The MOTOR CABLE should be below the axle and
TAB WASHER
, when the bike is standing with the wheels on the ground.
