Before riding your BiFrame bicycle, carefully follow all assembly
instructions. Make sure that all nuts, bolts and screws are securely
Make sure this bicycle fits the intended rider. Bicycles come in a
variety of sizes. Personal adjustment of seat and handleb~rs is necessary
to as'sure maximum safety and comfort. Bicycles come with a wide variety
of equipment and ac~essories; make sure that the rider can operate them.
Check the seat position, adjusting it up or down so that with the ball
of the rider's foot on the pedal in its lowest position. the rider's knee
is slightly bent. Rider should also be able to straddle the bicycle with
between 1.5" to 2" clearance above 'the top tube when standing with
both feet on the ground. Measurement for a woman's bike should be
determined using amen's model as a· basis (Figure 1).
All five of the BiFrame's quick releases must be securely fastened
b~fore riding the bicycle. The five quick releases are (I) the front wheel
qutek release (2) the front brake quick release, (3) the seat quick
release lever and (4 & 5) the top and bottom seat tube quick release levers
(Figure 2).
Make sure that apyone to whom you loan your BiFrame understands
how to work the quick release levers and how to fold and unfold the
BiFrame properly.
The owner is responsible for required normal maintenance services,
such as those listed in the ~;ection "Inspection and Maintenance" in th)s
booklet, to keep the bicycle in good operating condition.
The manufacturer is not responsible for failure, injury. or damage
caused by improper completion of assembly or improper maintenance
after shipment.
Great care should be taken when locking the quick release levers on the
• Move the quick release lever to the wide open position so that the word
"open" on the lever faces out, away from the bicycle.
• Tighten the adjusting nut in a clockwise direction by hand as lightly
as possible, as shown in Figure 3a.
• Flip the lever 180 degrees up aod over to the closed position (Figure
3b). You should begin to feel the lever resist movement as it approaches
the halfway point between open and closed.
• If the lever does not provide finn resistance, move the quick release
lever back to the open position and turn the adjusting nut a half turn
• If the lever can not be pushed in flush with the bike because it is too
tight. move the quick release lever back into the open position and
turn the adjusting nut one quarter turn counter clockwise.
• Repeat until' you feel resistance slightly past the halfway point.
• It should take a lot of pressure for you to push the lever into the closed
• To loosen the front brake for folding, pull the front brake quick release

CAUTION: It is very important tha'tyou use the quick releases properly
to ensure the safe operation of your bicycle. If any of the procedures
is unclear. have an authorized bicycle dealer demonstrate the proper
procedures to you.
The Montague BiFrame has been designed to fold and unfold quickly
and easily, without requiring. any tools. A few simple steps must be
followed. however. in order to assure safe operation and to avoid
scrat~hing or damaging the bicycle while it is being folded and unfolded.

• Tighten the front brake quick release
• Raise the seat as necessary.
• While the BiFrame is equipped with an automatic safety latch for your
protection. this safety latch is designed to be used only in conjunction
with the quick release mechanisms.
Observe all traffic regulations. Obey red and green lights, one·way
streets, stop signs, etc.
Ride with the traffic, not against It. Ride single file in a straight
Have satisfactory signaling device to warn of approach.
Give pedestrians the right of way.
Slow down at all street intersections and look to the right and left
before crossing.
Always use proper hand signals for turning and stopping.
Watch for cars pulling out into traffic and for sudden opening of
car doors.
Make sure the safety latch is in the locked position shown in
Fig. 5a before riding the bicycle.
Avoid potholes, drainage grates or other road
Cross railroad tracks at a right angle.
NOTE: The BiFrame can sometimes get caught in the folded position.
This can happen when the bicycle is not folded flat enough which causes
the pedal and crank arm to hit the down tube when rotated. If this
happens, manually turn the rear wheel in the direction it would spin if
the bicycle were being ridden. At the same time, turn the pedal and crank
arm in the same direction until they are in the proper position for
Never hitch on other vehicles, do not "Stunt" ride or race in'
traffic. Don't weave in and out of traffic or swerve from side to side.
CAUTION: It is very important to lock all five quick releases securely
before riding: (I) the front wheel quick relea'se lever. (2) the front brake
quick release, (3) the seat quitk release lever and (4 & 5) the top and
bottom seat tube quick release levers.
Never carry other riders or packages that obstruct vision or proper
control of the bicycle.
Before riding, check your brakes. Be sure they are operating
efficiently and that your bicycle -is in perfect running condition.
No brakes work as well under wet conditions as.they do under dry
conditions. In rainy or wet weather. special precautions must be taken
to insure safety in stopping. Proper adjustment and cable lubrication will
help, but the major precaution res~ with you. Increased lever forces are
required on wet or rainy weather arid care must be exercised to maintain
safety under these conditions. Ride slower than normal and apply your
brakes sooner than normal conditions would require.
If you do not understand how to fold and unfold the BiFrame. be
sure to ask your dealer for assistance.

WARNING: If you find it difficult to do the brake. fitting and
adjustment, it is recommended that the work be done by a qualified
bicycle mechanic. Do not attempt to ride the bicycle if brakes do not
function properly.
CANTILEVER BRAKES: Make sure the cantilever brazed-on
bosses on the frame or fork are clean and free of paint. Slide a brake
ann onto the boss; it must be able to spin freely on the boss. Remove
the brake arm. If the brake arm did not spin freely, clean the surfaces
with a fine emery cloth.
Apply a light grease1 to the ou tside surface of the boss. Do not get
any grease inside the threaded portion of the boss.
For the front brake, insert the straight end of the spring into the
hole in the boss, then mount the brake arms and engage the spring to
the brake arm for the right and left sides. Both of tpe rubber brake
shoes should be facing upwards. If they are not, switch the arms right
to left and left to right. Secure the brake arm in place by using the
washer (with serrations, if any, facing outward) and the mounting
bolt. If too much binding occurs during installation, remove the
mounting bolt and make sure the threaded area of the brazed-on boss
is free of debris.
Repeat the same procedure for the rear brakes.
CAUTION: Do not overtighten mounting bolts. This can cause
the stud to expand, impairing movement of the brake arms.
Position the brake shoes so that the rim face and the brake shoes
are aligned; (he top and bottom of the pac' should contact with the run
at the ·same time. If the rim face is deeper than the brake pad face.
the pad should contact the rim as high as possible without overlapping
the tire. Position the shoe so that when viewed from the top, the front
of the shoe strikes the rim slightly before the rear of the shoe. Secure
in place by using an allen wrench' to hold the brake shoe bolt in place
while tightening the nut. Tighten the nut securely at a torque of 6069 inch/pounds so that the brake shoe bolt cannot move.
Attach the straddle cable hanger to the 'straddle cable and insert
the brake cable into the hole in the cable anchor bolt in the straddle
cable hanger. Place the ends of the straddle cable into the ends of the
brake arms.
Adjust the clearance between the rim and brake shoe by moving
the brake cable through the cable anchor bolt and tighten securely.
Flex the cable and housing while squeezing the brake lever to seat and
compress the cable housing. Make sure that the casing is properly seated
in all casing lugs, ferrules, adjusting barrels and levers. Readjust the
shoe clearance using the cable anchor bolt to eliminate any slack in
the cable. Make sure that the braking action is effective well before
the brake lever touches the grip. Minor adjustments for the brake shoe
to rim clearance can be made by using the adjusting barrels on the
brake levers. Be sure to lock the adjusting barrel in place by tightening
the locknut against the brake lever.

Multiple gear ratios provide a means of maintaining a constant
pedaling rate, regardless of road level conditions. Mamtaining a constant pedaling rate is the most efficient cycling technique and is less
tiring over long distances than pedaling at varying rates and then
The derailleurs are activated by cables connected to shift levers
located on the handlebar. Derailleurs work by moving the chain from
one sprocket to another. The left lever controls the front derailleur and.
the right lever controls the rear derailleur.
Change only one gear (front or rear) at a time. Continue pedaling,
with relaxed pressure, while moving shift levers to the gear position
that allows the pedaling pressure and rate you find most comfortable.
Shift only when pedals and wheels are m motion. Never back-pedal
while shifting gears. Never· force the shift levers.
Chain noise often results from changing gears. If chain noise
continues after shifting, move the appropriate shift lever slightly
backward Qf forward to fine adjust chain alignment and eliminate the
taut and retighten nut securely.
With the right shift lever all the way back, the rear derailleur
should position the chain on the largest rear sprocket. Adjust limiting
screw "L" to allow for this and position it to bottom against the derailleur housing to prevent any additional inward travel of the rear derail·
leur. This will stop the chain from running off the inside of the large
rear sprocket.
REAR DERAILLEUR: With the right shift lever all the way forward, the rear derailleur should position the chain on the smallest rear
sprocket. If the chain does not reach the smallest sprocket, adjust
limiting screw "H" (moving it out, away from the derailleur housing)
allowing the necessary additional outward travel of the derailleur.
Once adjusted, limiting screw "H" should be moved to bottom
against the derailleur housing, stopping any additional outward travel
of the derailleur and preventing the chain from running off the smallest
With the rear derailleur positioned so tnat the chain is on the
smallest sprocket (right shift lever all the way forward), there should
be no trace of slack in the control cable. Normally a few counterclockwise turns of the barrel adjustment, where applicable, will take
up most of all of the slack in the cable. Wit doesn't, a cable adjustment
is necessary. Note, some derailleurs do not have a barrel adjustment
and therefore require a cable adjustment. If a cable adjustment is
required, loosen cable anchor 'nut freeing the cable. Pull the cable

in the rear dropouts. "If the dropouts have horizontal slots, move the
rear axle as far forward as is safely possible. This moves the rear
derailleur's guide pulley closer to the freewheel.
Center the guide pulley directly unQer the smallest freewheel cog
by adjusting the rear derailleur's high gear limit screw (H). This adjust.
ment is critical: Accushift indexing is keyed to this centered guide
pulley position. After adjusting the high gear limit screw, adjust the
low gear limit screw (l) so that the guide pulley centers directly under
the largest freewheel cog.
After cable installation, push the shift lever a few times to remove
initial cable slack. Then retighten cable.
Confirm that the chain is the correct length by shifting in 10 highest
gear (smallest. freewheel cog and largest chainring). Then, while holding
the rear derailleur body parallel to the chainstay, locate the small dot
on the pulley cage (on the Alpha 3000, the rear derailleur uses the cage
pivot stop pin as reference instead of a dot). If the chain is the correct
length, then the dot will line up with specif1c reference marks on the
main body of the rear derailleur.
Turn the angle adjusting screw counterclockwise as far as possible.
This rotates the rear derailleur forward, pUlling it even closer to the
freewheel and optimizing guide pulley placement. If the guide pulley
is too close to the freewheel, it will not be able to shift the chain off
the largest freewheel cog. If you notice this, turn the angle adJustlDg
screw clockwise to move the rear derailleur back. Adjust until the
chain shifts off the largest cog. In most cases, the angle adjusting
screw can remain all the way out.
In order to fine tune for perfe~t shifting performance, start with
the largest freewheel cog and shift to the next smallest cog. Adjust
cable tension at cable adjusting barrel if required. Continue through
all cogs,. then shift up to ensure adjustments. If necessary, you can
easily turn the cable adjusting barrel by pushing the shift lever back
to loosen cable tension. Make sure the guide pulley aligns with each
cog during this process.
With the chain on any freewheel cog (except the innermost) and
the shift lever in "Index" mode, move the lever slightly, taking up the
small amount of free movement designed into the system. The ~ear
derailleur must move a corresponding amount. If it does not, there is
a cable binding problem. The source of the drag must be located and
eliminated. Be sure all cable routes are free of dirt, grit, filings and
grime. If necessary, clean and grease the cable guide under the bottom
There are four places on the bicycle that contain bearings that may
require adjustment: the headset. front hub. crankset and rear hub.
HEADSET BEARINGS: To check bearing adjustment, lift up
handlebar at the grips. There should be no play of the handlebar stem
and fork. but the handlebar must be able to turn freely and easily.
To adjust. remove head lock nut ~n.d reflector bracket. Turn the
