Adjusting The Air Suspension Fork Rebound; Adjusting The Fox Fork; Adjusting The Negative Deflection - Bosch BULLS Twenty 6 EVO Translation Of The Original Operating Instructions

7 Sit on the pedelec in your usual riding position
and support yourself against an object, such as
a wall or tree.
8 Get off the pedelec without allowing it to
deflect.
9 Measure distance between the dust seal and
the cable tie.
 This measurement is the negative deflection.
The recommended value is between 15%
(hard) and 30% (soft) of the total fork
deflection.
10 Increase or reduce air pressure until you have
reached the desired negative deflection.
 If the negative deflection is correct, turn the
valve cap in a clockwise direction.
 If you are unable to achieve the desired
negative deflection, an internal adjustment
may be needed. Contact your specialist dealer.
6.5.6.4 Adjusting the air suspension fork
rebound
Only applies to pedelecs with this equipment
The rebound setting depends on the negative
deflection setting: A higher negative deflection
requires a lower rebound setting.
1 Turn the Suntour rebound screw in a
clockwise direction to the closed position until
it stops.

2 Turn the Suntour rebound screw slightly in an
anti-clockwise direction.
3 Adjust the rebound in such a way that the fork
rebounds quickly, but without bottoming out
upward. Bottoming out refers to when the fork
rebounds too quickly and stops moving
abruptly once it has reached the full rebound
distance. You can hear and feel a slight impact
when this happens.

Adjusting the FOX fork

Only applies to pedelecs with this equipment
Crash caused by incorrectly set suspension
If the suspension is set incorrectly, the fork may
become damaged, meaning problems may occur
when steering. This will cause a crash with
injuries.
 Never ride the pedelec without air in the air
suspension fork.
 Never use the pedelec without adjusting the
suspension fork to the rider's weight.
Settings on the chassis change riding
performance significantly. You need to get used
to the pedelec and break it in to prevent
accidents.
It is recommended to note down the determined
negative deflection and rebound levels. This way,
the levels can be used as a starting point for
subsequent, optimised settings and as a
safeguard against unintentional changes.
The adjustment shown here represents a basic
setting. The basic setting can be adjusted to the
riding surface and personal preferences.

6.5.7.1 Adjusting the negative deflection

1
Negative deflection depends on the rider's weight
and sitting position. The recommended negative
deflection is between 15% (hard) and 20% (soft)
of the total fork deflection depending on
preferences and pedelec use.

When adjusting the negative deflection, ensure
that each pressure level adjuster is in an open
position, i.e. each pressure level adjuster has
been turned in an anti-clockwise direction until it
goes no further.

The pressure is to be measured at an ambient
temperature of 21 to 24 °C.
