Ener-

sure is 5 bar. When using other tires please
pay attention to their maximum allowed pres-

Spokes
The spokes of the wheels connect the rim to
the hub. They transmit the braking power of
the disc brakes, and in addition they transmit
the pedal forces at the rear wheel.
The tricycle requires a high spoke tension
(> 1000 N) as the wheels have to bear high
side loads. Any damaged spokes must be re-
placed immediately.
Attention!
To true up the
wheels you need special skills, please have
this work done by an experienced bicycle
mechanic.
Danger!
Take care that your
spokes are always in perfect condition and
the spoke tension is balanced. Do not ride
with wheels that run untrue or wheels
with loose or missing spokes. These faults
may lead to a total failure of the wheel
while braking and result in a serious fall!
