HUSK-E usage instructions
20.5.2 Parking brake
A mechanical disk brake with a locking
lever is installed as a parking brake as
standard. Turning the lever applies or releases
the brake, and the lever always maintains the
set position. If the brake was applied while
stationary, it must be released before starting
the trip.
Figure 26: Parking brake over locking lever
Alternatively, an aluminium bracket that is
attached to the bottom bracket support is an
option. With it, one of the two brakes can be
used as a parking brake. For this purpose, the
aluminium bracket is clamped over the grip
and the brake lever while the brake lever is
depressed.

20.5.3 Back-pedalling brake on the
Shimano Di2 hub gear
The back-pedalling brake is operated by
rotating the crank backwards. The braking
force applied is adjusted by the strength of
rotating the cranks backwards.
20.5.4 PRO ACTIV back-pedalling brake &
crank release function
The PRO ACTIV back-pedalling brake is a
closed hydraulic system consisting of a
generator unit and a disc brake calliper. The
system has automatic wear compensation for
the brake pads.
To adapt the system to body weight and the
physical limitations of the user, the springs of
the system are available in three strengths.
These can also be replaced retrospectively.
Contact your rehabilitation specialist dealer
immediately, who will arrange for the
replacement of the springs by PRO ACTIV.
The back-pedalling brake is delivered with a
crank release function which allows reverse
driving and manoeuvring via the hand rims. As:
For functional reasons, the back-pedalling
brake always acts as soon as the product
moves backwards. Therefore, the user must
"unlock" the reverse movement first by
operating the crank release function.
The braking function via the backward
movement (crank movement against the
direction of acceleration) is always guaranteed
– with the crank release function activated or
deactivated.
The braking force applied is adjusted by the
strength of rotating the cranks backwards. The
braking force applied is adjusted by the
strength of rotating the cranks backwards.
The crank release function is operated by
pressing the side pressure plate. To activate
the crank release function, the left-hand
pressure plate must be operated (seen from
the direction of travel). To return to normal
driving operation with the back-pedalling brake,
the right-hand pressure plate must be
operated.
