load index according to the maximum permit-
ted axle load (front: 28, rear 26).These indexes
are shown on the tire’s sidewall.

Energizer“ (series tires) the recommended
pressure is 5 bar.When using other tires plea-
se pay attention to their maximum allowed

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.

Danger!
Take care that your spokes are al-
ways in perfect condition and the spoke ten-
sion 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!
The wheels are fastened with a quick release
mounting and therefore they are susceptible to
theft. For this reason always lock the wheels
along with the frame to a solid object when
you park your bicycle somewhere.
To remove a front wheel, loosen the bolt in
the locking part at the inside of the knuckle at
least 6 mm. Pull the locking part away from the
knuckle. Pull the wheel a few mm away from
the knuckle and slide the axle through the slot
in the knuckle.
Take care not to bend the brake disc.When
reinstalling the wheel, slide the disc carefully
between the brake pads and take care not to
damage them. Tighten the screw in the locking
part with 8–10 Nm.
Taking out the front wheel after loosening the screw in the
locking part.
Caution!
To true up the wheels you need
special skills, please have this work done by
an experienced bicycle mechanic.
