About this manual
Scope
This manual contains parts diagrams, specications (such
as grease and torque values), instructions and helpful tips
(such as the easiest direction to route cables).
This manual does not contain instructions on all
components (such as brake callipers). Refer to the original
manufacturer for more information.
Working on a front cargo bike
The length, weight and box size make working on this
bicycle more difcult. Do not use a regular repair stand to
lift the bicycle – use a ceiling-mounted hoist.
If you do not have a hoist, you can do many repairs by
tipping the bicycle on it’s side.

Warnings
WARNING
Tighten hardware properly
Always tighten hardware to the specied torque.
Over-tightening hardware could deform or break the
hardware or components. Under-tightening hardware
could cause hardware or components to become loose.
Either situation could damage the bicycle and result in
injury to the rider.
WARNING
Re-apply threadlocker
All reused-fasteners with a pre-applied threadlocker
must be cleaned with isopropyl alcohol and have new
threadlocker applied before re-assembly. If a threadlock-
er is not applied, the fasteners may loosen, which could
damage the bicycle and result in injury to the rider.

Steering: adjust cable tension
1. Loosen the four rear cable mount bolts (2) – do not
remove them.
2. Hold the tensioning bolt (4) in place and use a 13
mm wrench to loosen the tensioning nut (5). Then,
loosen the tensioning bolt (4) to remove tension from
the cables. Repeat for the other side.
3. Move the cable mount (6) to increase tension in the
cables.
4. Tighten both tensioning bolts (4) – alternating
between them to keep the cable mount parallel –
until they are snug into the cable mount (6). Then,
tighten both tensioning nuts (5) to 18 Nm.
5. Test the front wheel steering and adjust the cable
tension, if necessary. There should be no noticeable
slack when steering quickly.
• Too loose – the wheel will feel disconnected from
the steering.
• Too tight – the steering will feel heavy with a lot of
friction.
Notice: If the cables are too tight, the bearings
will wear out much faster than if the cables are
tensioned properly.
6. Tighten all four rear cable mount bolts (2) to 18 Nm
(see Step 1).
7. Tighten both tensioning nuts (5) to 18 Nm.

Steering: replace steering cables
Replace all four cables every two years or 10,000
km/6,000 mi.
NOTE: If a cable is damaged and needs repair, replace all
four cables – not just the damaged one.
Remove the cables from the rear disc
1. Cut the three zip ties connecting the steering cables
to the frame (see the zip tie locations on page 1).
2. Loosen the four rear cable mount bolts (2) – do not
remove them.
3. Hold the tensioning bolt (4) in place and use a 13
mm wrench to loosen the tensioning nut (5). Then,
loosen the tensioning bolt to remove tension from the
cables. Repeat for the other side.
4. Remove the two bolts (11) securing the steering
cables in the rear cable mount.
5. Slide the cable mount (6) towards the steering disc to
relieve tension on the cables.
6. Remove the cables from the steering disc.
Remove the cables from the front disc
1. Loosen the two bolts (11) securing the steering
cables in the front cable mount (1).

Insert the cables into the front disc
NOTE: The cables may be slightly different lengths – there
is no certain order in which you need to install them. They
will stretch and even out after use.
1. Route the four cables through the frame brackets.
2. Route one cable into the lower section of the front
steering disc. Then, route another cable in the upper
section. Install one bolt (12) into the cable mount
and torque to 4 Nm to secure the two cables.
IMPORTANT: Make sure the cable end stop is fully
inserted into the cable mount or you will not have
enough slack when you install the cables in the rear
disc.
