Hase Spezialräder TRETS User manual


Dear Customer,
Important! Think of your child's safety. To safeguard your child
while it is cycling on the Trets, make sure it is strapped in and
that the safety harness is secured at all times during the trip!
Trets, the children's trailer-bike with crank and pedals, allows children to
learn cycling actively and safely. The sitting position can be adjusted infinitely
for children of different heights. The three-point safety harness guarantees
optimum protection for young co-cyclists. The low-lying centre of gravity
increases stability and, therefore, safety. In addition to these strong-points,
the 7-speed gearing system allows children to actively participate in the
cycling.
To ensure long-term enjoyment of a piece of technical equipment such as the
Trets, maintenance must be carried out regularly and worn-out parts
replaced. This maintenance manual is intended to provide you with the
technical instructions you need to ensure that your child can use and have fun
with the Trets for the longest time possible.
Your experiences in daily cycling life or on cycling tours are of great interest
to use. Have you any recommendations for improvements, have you
complaints or criticism to offer? Please let us know, we would be glad to hear
from you. Your information can help us to make the Trets an even better
cycle for you and your children.

If the Trets has been shipped to you, it is important to observe the following:
On receipt of shipment:
Check the packaging for any damage and have it confirmed in writing by the
mail delivery person. Passage of risk takes place in Waltrop, in the case of
transport damage, the shipping company bears liability.
Scope of delivery:
Check first if the shipment
is complete. In addition to
the Trets, the following
components must also be
present in the shipment:
!Two 6 mm retaining screws with washers for fastening the
mudguard (already screwed into seat-frame)
!Two aluminum space holders for the mudguards (already fitted
onto seat-frame)
!Mudguard for left-hand wheel
!One 12 mm hexagon socket screw (Allen screw) for fastening
the wheel
!One flag with pole
Assembly:
When you have unpacked your Trets, you must first of all fit the mudguard (for
assembly instructions, see Page 8). When you have finished fitting the
mudguard, you can mount the left-hand wheel. To do this, tighten the supplied
12mmm retaining screw applying a torque of 75Nm. Now you must adjust
length and tracking (Page 5). Assembly of the Weber coupling onto the parent
or host bike is described on Page 6.
We would recommend that you have assembly and adjustments carried out by
your specialist dealer.

Length and Tracking Adjustment

Tracking adjustment
The rear wheels of the Trets are mounted on axles that do not stand parallel to
the road surface; this makes tracking adjustment essential for keeping tire wear
to a minimum. To adjust the tracking on your Trets, proceed as follows:
• Assemble the Weber coupling on the host bicycle as described on the
following page • Hitch the Trets onto the host bicycle • There are two 8 mm
clamping screws on the front of the boom where the tow-bar is inserted. These
screws must be loosened, but only drawn so far out that the tow-bar can be
turned and raised without it slipping back down again • Now adjust the length
by placing a meter stick vertically on the ground beside the quick release lever
on the Trets main frame tube. As shown in the photograph below, the distance
between quick release and ground must measure 250 mm • When the correct
position has been found, tighten the clamping screws on the main tube.

Length adjustment
The Trets can be adjusted in length by
170 mm without the chain having to
be shortened. To make this
adjustment, open the quick release
lever on the left-hand side of the
Trets. Now you can adjust the length
of the Trets by sliding the boom up
and down within the frame tube as
required. When you have adjusted
the boom to the desired length, the
quick release lever must be closed
again. Caution: The quick release must be closed firmly when adjustment has
been completed. If it is not firmly closed, there is a danger of accidents
or damage to the frame.
When length has been adjusted, height must be adjusted accordingly

We would recommend that you
have assembly of the Weber
coupling carried out by your
specialist dealer.
Assembly
Push the Weber coupling and the broad
washer onto the host bike's rear axle
and secure by tightening the axle nut
or the quick release (photograph on the
For correct connection, the coupling
must be turned so that the flattened sides
of the coupling and trailer tow-bar are
turned outwards. Connect trailer tow-bar
and coupling and turn the security lock
until the safety pin locks into place (see
photograph).
Additional safety strap: As an additional
security attachment, the Weber coupling
also has a safety strap to ensure that the
trailer cannot disengage from the host
bike if the coupling becomes undone or
opens. To attach the strap, thread it
through the rear frame triangle, feed the
free end through the buckle fastener and
pull tight to secure (see photograph on
the right).

Caution: Protect your child
from injury and strap it into
the Trets with the safety
harness before every
journey!
To fasten the safety harness correctly,
proceed as follows:
Lay the two single belt clasps together
as illustrated in the photographs on the
right. Then push the joined clasps into
the harness catch until the closing
mechanism locks into position with an
audible clicking sound. When the halter
is shut, the strap lengths can be
adjusted. Both straps are threaded
through holders mounted on the seat
and then fed through a buckle fitted on
each strap. The strap can be adjusted in
length by loosening and tightening with
the buckle. The belt has the correct
tension when your open hand can be
easily placed between passenger and
belt.

Gearing
The Trets has a 7-speed derailleur
gear system with a grip shifter. Your
child can adapt easily to the traveled
speed and pedal along actively with
the adult. The gears can be changed
during forward pedaling. The gear
actually in use is displayed on the grip
(see photograph).
Care of the gear system:
Occasionally oil the shift cable and the
shifter. The chain and chain guide
roller on the shifter must be cleaned
when necessary and oiled lightly. Do
not use a high pressure cleaner to
clean the gear system as the pressure
of the water drives the lubrication out
of the bearings.

We recommend using the flag delivered with the Trets. The

Flag
The borehole for holding the flag is on
the top of the seat on the right (see
photograph on the right). You can feel
the entry with you finger through the
seat cover material. Before inserting
the flag, pierce the seat cover with a
sharp blade or mandrel above the
hole. The flagpole must then be
inserted and pushed in as far as
possible.

Mudguards
The mudguards can be adjusted in height. To adjust the mudguards, you must
loosen both the mudguard retainer screws. The elongated hole in the holder
allows the mudguard to be slid upwards or downwards to adjust height.

Helmet:
For safety reasons, we recommend wearing a safety helmet during every
cycling trip on every bicycle.
Clothing:
When riding in the Trets, the passenger should wear close-fitting clothes that
cannot catch in a wheel or the drivetrain. Be on the alert and watch out for
loose-hanging straps, cords, clothing, for instance from jackets or scarves.
Risk of injury:
Do not touch the drivetrain in any way while the Trets is in motion.
Cycling at night:
Always cycle with the lights on during trips in semi-darkness (dusk/dawn) or in
darkness. For cycling in the dark, the Trets must be fitted with a battery-driven
rear lamps. These lamps are available from bicycle dealers.
Tire pressure:
Check your tire pressure, preferably before every trip. To achieve optimum
results for low resistance and smooth performance, we recommend observing
the tire pressure stamped onto the tire. The original Trets tires, Continental
Top Touring 2000 47-406, have a maximum pressure of 4 Bar.
Important:
The higher the pressure = the lower the resistance
The lower the pressure = the greater the traveling comfort
Chain:
The chain of the Trets is longer than in conventional bikes. This leads to less
wear. If you want to know whether the chain is worn and must be replaced,
your cyclist dealer can find out by using a special wear gauge.
