6.1.2. Rear wheel installation
To install the rear wheel, please follow the steps below:
1. Ensure the upper chain is lying on the cassette, while
the lower part of the chain is running underneath the
cassette and is not blocking the dropouts.
2. Ensure that both the disc rotor and the brake caliper
are perfectly aligned to avoid any damage to the frame or
brake caliper.
3. Carefully slide the rear wheel into the dropouts. Please
ensure that the motor connector is facing upwards and is
aligned with the dropout. Once the wheel sits smoothly in
the dropouts, guide the axle through the motor and
tighten it to the frame manufacturers recommendations.
Once the axle is tight, the motor is automatically
connected to the rest of the system.
WARNING
Always ensure that both, the motor and the frame side of
the automatic connector are clean before installing the
rear wheel. Check the connector before installing the rear
wheel – all pins should be straight. Should you need
support installing your rear wheel, please reach out to
your local dealer.
6.2. Other Services
Your X20 System does require regular servicing and
some components are suspect to wear. To always ensure
your eBike is working as intended please ensure regular
service. If any of the components needs to be replaced,
please get in touch with your local dealer for further
support.
6.2.1. Freewheel and bottom bracket
service
The X20 System does feature a fully replaceable
freewheel and bottom bracket which both require regular
servicing.
For both freewheel and bottom bracket installation, there
are guidelines that explain the process step by step in
detail.
Any kind of replacement or service needs to be
performed by a professional mechanic. Always ensure
that no wires or connectors are damaged in the process
of installing or removing system components. Before you
perform any kind of replacement, please read the
recommendations of both MAHLE and the bike
manufacturer, including all additional information about
bicycle maintenance and care. Pay special attention to
the guidelines of the bottom bracket removal and
installation.
6.2.2. Battery, Motor, Head Unit Service
Should a new battery be required, please be aware that
the replacement can only be performed by a professional
mechanic. We therefore recommend getting in touch with
your dealer prior to the replacement. Additional steps
such as the activation of the battery may occur for various
components which can only be performed by an
authorized MAHLE service partner.
Please be aware that MAHLE only warrants the X20 Drive
Unit which is the rear hub of your eBike wheel. Should
you face any issues with your spokes or rim or other parts
of your rear wheel, please get in touch with your bike
manufacturer directly.
NOTICE
MAHLE SmartBike Systems components require a
specific software activation. Pay special attention when
replacing the BB, the Drive Unit, the battery or HMI. In any
case, replacements must only be performed by
professional mechanics.
