WARNING:
Do not route the phase
wires (2 above) and the Hall sense cable
(3 above) next to each other over their
entire length. Space them at least an
inch (25mm) apart over most of their
length. The high currents in the phase
wires can interfere with the low voltage
signals in the Hall cable and destroy the
controller.
Step 11: Check front Derailleur Adjustment
Triple chainring version only: Test front de-
railleur adjustment and adjust as needed.
It’s especially important to adjust the derail-
leur so it doesn’t over shift on the big ring and drop the bike chain onto the motor chain.
If you don’t know how to adjust your derailleur you can ask your local bike shop to do it, or go to:
http://www.parktool.com/repair/readhowto.asp?id=75
on the Park Tool Company web site for an excellent how-to article on front derailleur adjustment.
Single chainring version only: If switching from a triple chainring to single chainring,
leave the front derailleur in place and adjust it so that the bike chain is centered in the
cage.
This will provide extra protection to keep the chain from coming off the front sprocket on sharp bumps.
Step 12: Finish up and Test.
1) With the rear wheel suspended off of the ground, turn on the battery pack switch and
press the throttle to test the system. Run the bike through all of the gears to make sure the
derailleur is properly adjusted. Look at the motor chain and verify that it is running
smoothly. Make sure that all wires are out of the way of all moving parts. Make sure axle
bolts or skewers are tight
2) Once you’re satisfied that everything is operating correctly, neatly tie all wires out of
the way of moving parts using the included cable ties.
Proper adjustment of the gears and making sure that the rear cassette and bearings are in good shape is
especially critical given the extra load the drive train will be subjected to. Also, check that the rear axle
skewer or bolts are fully tightened. Axle bolts should be torqued to about 20 ft-lbs (28 Nm). Skewers
should be as tight as you can comfortably make them. It is possible for the motor to pull the axle right
out of the dropouts if they are loose.
3) Road test.
Run through all the gears making sure they are shifting smoothly. Use full throttle in each
gear to check for skipping of the drive chain. Keep speeds low at first until you’re sure that everything is
functioning properly and you become familiar with riding with the motor assist.
Congratulations! Your install is complete!
