Basic Maintenance and Care
Disconnecting the Rear Wheel
Switch eBike power “off” and dis-
connect the eBike battery (if possible).
Remove the Harmony or Harmony
H|Sync Main Connector at the
rear wheel.
Grab the connector at the ribbed
location (1) and pull lightly away from
the Harmony or Harmony H|Sync
Hub Interface.
Loosen and remove the axle nuts (2)
and the no-turn washers(3).
For rim and roller brake applications,
disconnect the rear brake according
to the manufacturer’s instructions.
Remove the rear wheel.
Some bicycles may require rotating
the CVP Axle and Harmony or
Harmony H|Sync Hub Interface to al-
low removal of the bicycle chain.
In some cases, it is easiest to remove
the chain from the front chain ring to
ease rear wheel removal.
Do not pull on the cable, only
at the ribbed connector half
as shown.
The connector supplies electrical
power to the Harmony or
Harmony H|Sync unit. Protect
the connector from water or
other conductive elements when
disconnected, as shock or dam-
age to the system could result.
