INTRODUCTION
This manual is intended for those who have bought
their Morpheus directly from Circe Cycles and
have received their tandem packed in a box.
This manual is to help you unpack and assemble
your tandem. After this you can refer to the
Owner’s manual to help with adjustment and more
comprehensive setup.
To further help with assembling your tandem, there
are instructional videos available on the manuals
page of our website.

UNPACKING
Make sure that both boxes are the correct way up
before opening. Remove all the loose packaging
and any loose parts from around the bike. Remove
the tandem from the box, a second set of hands
makes this easier.
The seat, small components and accessories
comes in a separate box to the main part of the
tandem, please follow the same procedure as
above for unpacking.
NOTE - Check that everything is present and
undamaged before proceeding to assembly.
CONTENTS OF MAIN BOX

• The tandem with the captain’s handlebars
folded down and to one side of the frame
• Racks*andrearstand*shouldbettedtothe

NOTE – The P clip holding the cables should be on
the inside of the clamps and on the left hand side
of the bike.
Thelowerseatmounttstotheframeviaabolt
and lever. There are three potential positions for
the bolt to be in, depending on the desired position
of the seat. The bolt is tightened by rotating the
black lever clockwise, whilst holding the nut on the
other side. The lever can’t rotate fully because of
the seat, so it is possible to disengage the lever by
pressing the red button and pulling the lever out,
allowing it to be rotated freely back to a suitable
starting position.
INSTALLING STOKER HANDLEBARS
The stoker bars slide into the tube to the rear of the
lowerseatmountingpoint,andarexedinplace
using the quick release clamps. The bars should be
positioned so the foam grip is facing forward and
slightly tilted up.
NOTE - f you have a Front stand the stoker bar is
used to hold the upper clamp.
• 10mm spanner (Front stand, Kiddy system)
• 15mm pedal spanner
POSITIONING THE CAPTAIN’S HANDLEBARS
Remove any zip ties that are holding the handlebar
and loosen the four stem bolts using an Allen key.
The bars can now be turned to an upright postition,
a good starting point is shown below, but can easily
be adjusted to suit your riding style. The stem should
facing towards the back of the bike and needs to
alignedwiththefrontwheel,thenxedinplaceby
tightening the two pinch bolts on the stem.
The handlebar extensions are adjusted using a
quick release and should be fully tightened before
riding. Once the handlebar and front wheel are
aligned the stem bolts should be tightened to the
recommended torques settings in the torque table
Appendix A.
NOTE – It’s easier to align the handlebar and front
wheel with the stoker seat removed.
INSTALLING STOKER SEAT
The stoker seat mounts to the frame at two
locations. The upper mount has two tubes which
slide into the corresponding clamps on the frame.

INSTALLING THE BOOM
First, remove any packaging from around the
end of the main tube on the bike, including the
transportation bung, which is inserted into the
end of the boom to prevent damage. The boom
can then be slid into the main tube and the
chain looped over the chainring. The boom can
be set to the length required and the two pinch
bolts tightened to the recommended torque, see
Appendix A
NOTE – Tighten the pinch bolts evenly to prevent
damage to the frame
ADJUSTING THE TIMING CHAIN
The timing chain can be tensioned by undoing the
quick release on the tensioner arm and rotating
the arm to take up the slack in the chain. If the
tensioner alone can’t take up the slack in the
chain, it is possible to shorten the timing chain by
removing some chain links.
INSTALLING THE FRONT STAND
(Optional extra) The bike is packed with the lower
standbracettedtothedowntube,themain
section of the stand is packed separately in the
small parts box. The stand mounts to the frame at
two points; the upper clamp, slides over the stoker
bars, as shown earlier in the manual. The lower
mount is via the brace, the arms of the brace need
to be bolted to the main body of the stand using
the supplied nut and bolts.
INSTALLING THE KIDDY SYSTEM
(Optional extra) The Kiddy system main body
should be mouted to the main tube of the tandem,
the crank assembly will be pocked separately in
the small parts box.
To mount the crank assembly to the main body, the
T nuts need to be aligned with the corresponding
slots in the main body.
NOTE – It’s easier to mount the T nuts to the channel
if one T nut has the long end facing out with the
opposite side T nut facing in.

Once the crank assmbly is positioned on the main
tubeitcanbexedinplaceusingthefourM6hex
bolts and a 10mm spanner.
INSTALLING THE PEDALS
(Your own if not ordered from us) – The pedal
threads are handed. The right hand pedal tightens
in the normal direction; the left-hand pedal has
a left-hand thread, and tightens in the opposite
direction to normal. Tighten the pedals to the
torque shown in Appendix A.
BELL AND REFLECTORS
Reectorsandabellaresuppliedwithyour
tandem. The bell can be mounted anywhere on
the handlebars where it can be reached easily.
Thefrontreectorcanalsobemountedtothetab
ontheendoftheboom.Therearreectortsto
theCaptain’sseatpost,ensurethatthereectoris
visible at the height you intend to have the post at.
Ifnot,youmayneedtorepositionthereectorso
that it is visible.
PRE-RIDE
Check all nuts, bolts and quick releases to make
sure everything is tight (See appendix A for torque
settings). Ensure the wheels spin freely and the
brakes function correctly.
FIRST RIDE
Check the gears shift correctly, refer to the Owner’s
manual, or manufacturers manual, for adjustment.
Payattentiontothetandmakeanyadjustments
required, once you are stationary. Finally, ensure
there are no rattles or unexpected sounds.
YoucannowrefertotheUser’smanualfornalset
