Adjusting The Compression In A Rockshox Damper; Gear Shift; Using The Derailleur Gears; Using The Hub Gear - Bosch BULLS Twenty 6 EVO Translation Of The Original Operating Instructions

6.16.6 Adjusting the compression in a
RockShox damper
Only applies to pedelecs with this equipment
The compression damper controls the speed at
which the rear frame damper deflects during slow
impact, such as smaller impacts or when the rider
goes round a corner or shifts their weight. The
compression damper improves control and
efficiency.
If the compression damper is set too high,
suspension is too hard when exposed to impacts.
The damper lever is used to set the compression
damper.
 Turn the setting wheel in a clockwise
direction (+) to decrease the deflection speed.
 Turn the damper lever in an anti-clockwise
direction (–) to increase the deflection speed.

Gear shift

The selection of the appropriate gear is a
prerequisite for a physically comfortable ride and
making sure that the electric drive system
functions properly. The ideal pedalling frequency
is between 70 and 80 revolutions per minute.
 Stop pedalling briefly when changing gears.
This makes it easier to switch gears and
reduces wear on the drivetrain.

6.17.1 Using the derailleur gears

Only applies to pedelecs with this equipment
The speed and range can be increased while
applying the same force if you select the right
gear. Use the derailleur gears.

 Select the appropriate gear with the shifter.
 The gear shift switches the gear.
 The shifter returns to its original position.
 Clean and lubricate the rear derailleur if the
gear change blocks.

6.17.2 Using the hub gear

Only applies to pedelecs with this equipment
CAUTION
!
Crash caused by incorrect use
If the rider applies too much pressure on the
pedals during a gear change and activates the
shifter or changes several gears at a time, their
feet may slip from the pedals. This may cause a
crash or flip-over with injuries.
Switching down several gears to a low gear may
cause the twist grip outer sleeve to suddenly
come off. This will not have an adverse effect on
the twist grip's correct functioning since the outer
guide returns to its original position after the gear
change is complete.
 Apply little pressure on the pedals while
changing gears.
 Never change more than one gear at a time.
