5.2 Attaching the drive wheel
Make sure that all the components attached to the wheel have been installed in accord-
ance with the instructions and specifications of the respective manufacturer. This relates
in particular to the brakes and the gear box. Do not forget to reinstall the torque support
[20] in the same position as it was taken from.
Then push the wheel into the slot of the frame and tighten it using the hub axle nuts
[18] in the following sequence:
•
first tighten on the side of the gear box (diagram A)
•
then on the side of the brakes (diagram B)
In each case, the tightening torque of the two nuts is between 30 and 40 Nm.
Ensure that the tooth lock washer [19] is located beneath the axle hub nut otherwise
there is the risk of the axle hub nut [18] coming loose.
If your wheels are equipped with a quick-release mechanism, please observe the manu-
facturer’s specifications on installation and the tightening torque.
If the wheel is correctly attached to the frame, the motor with the end of the cable that
leads to the battery can be connected. In doing so, make sure the plug [15] is correctly
aligned with the socket [17]. The curved surfaces ([A] and [B]) must be aligned with
each other.
Then fasten all cables and leads with cable ties to the bicycle frame and perform a final
function test.
Make sure the cables are laid correctly as failure to do so could mean
the cable getting caught in the brake disc, the drive or the spokes
and by locking the wheel cause a fall.
It is essential to observe the instructions and specifications of the
manufacturer of the various components attached to the wheel in all
your installation work. This particularly applies to the brakes, the
gear box and quick-release mechanism.
Never install the motor without the torque support [20]. This could
cause a total loss (twisting off the cable). This voids all warranty or
guarantee claims.
Carry 5 cable ties with you along with your repair tool, to securely
fasten any loose cables during a trip.
Installing or removing the drive wheel is best carried out when the
Pedelec is upside down (standing on its handlebars and saddle).
Remove the sMMI attached to the handlebars first so that it does not
get damaged.
Always use the original gear cluster built by the bicycle manufacturer.
Using other makes may lead to restricted function or to the gear
cluster scraping the chainstays.
