Tricycle Fit
For safety reasons it is important that the rider must be able to ride in a comfortable manner.
Your tricycle dealer will ensure the tricycle is suitable and safe for you to ride.
After a short time of riding you may feel more confidence and consider resetting the seat height and the handlebar
position that was set by the dealer.
Height of the seat and the position of the handlebars can be fine tuned for your riding enjoyment.
It is important to remember that different riding conditions will change the characteristics of the tricycle.
Gomier Manufacturing as manufacturer, and Bike Solutions as distributor, are not responsible for
failure, injury, or damage caused by improper completion of the assembly prior to riding or lack of
future maintenance of your tricycle.
Let’s get started.
As the rider of this tricycle you must be able to sit on the saddle in the normal riding position and have your feet
positioned with the heel raised and the toe of your foot just touching the ground.
Seat Post
Now set the seat post securely ensuring the minimum insertion line is not visible outside the frame
If it is not possible to set the seat post with the minimum insertion line not showing, then the seat post needs to be
changed for a longer version.
If it is necessary to change the seat post for any reason it is important to replace it with the correct diameter size
namely 26.8mm.
Handlebar height
If your handlebar requires adjustment ensure that the minimum insertion mark is not visible then tighten the stem
expander bolt and the handlebar binder bolt on the headstem to the required torque measurement of 20-23Nm.
In the unlikely situation that the conditions of braking has changed during these modifications
re-adjust the front brake pad clearances to the rim and reset the front brake cable adjustments.

Basic maintenance
Regular inspection and maintenance
Regularly check that all bolts and nuts are tight. Check all components to see if any are worn or
damaged.
Even though damage caused by accidents will void the frame and fork warranty it is very important for
your safety that you inspect the frame for signs of misalignment or breaks in the tubing especially
around welds.
Inspect the forks for misalignment or rake movement.
If there is evidence of damage or misalignment, return the tricycle to the dealer from where it was
purchased for a full assessment and quotation for the repair or replacement of the damaged part.
Other qualified technicians are listed on our website www.bikesolutions.com.au.
Braking
This tricycle is fitted with dual braking.
Coaster footbrake operated by pedalling in reverse to stop.
Ensure the brake operates smoothly without locking or grabbing when applied normally. Keep brake
arm securely attached to the frame by the retaining bolt and nut.
Front linear brake calliper and lever mounted on the handlebars to your local authorities regulations.
Ensure brake shoes are adjusted correctly (refer Page 5 Fig 1)
Replace worn or missing shoes.
Inspect the braking surface of the rims for damage and wear and keep surface clean.
Brake cables ( 2)
Replace worn, damaged or frayed cables. Ensure cables are not kinked and especially take note that the
front brake cable does not become hooked up with any attached bag or basket or any item being carried
on the front handlebar assembly which could cause the brake to be partially on.
Gear lever ( external gear model)
Check gear lever assembly is correctly positioned and tight.
Front fork
Bent or damaged forks should be replaced. Never attempt to repair by straightening.
Important: Front forks with the same inside diameter, wall thickness and angle of rake must be used
when replacing the front forks.
Head bearings
Keep well adjusted. The forks should always turn smoothly and the fittings should never feel loose and
the rider should never feel vibration.
Front wheel
Keep both wheel nuts tight. 22-27Nm (195-239in-lb)
Wheel must be always centred in the fork to ensure correct and safe braking. Ensure the front wheel
spins freely with the bearings correctly adjusted. Keep spokes tight and check the rim is straight and
true.
This front wheel is very important for your safety so if you are not experienced to carry out this work
refer to your dealer.
For other qualified technicians refer to our website www.bikesolutions.com.au.
Drive train
Crank bearings should turn freely without any side play. Keep locknut tight (remember tightening is
clockwise). Bearings should be well greased and clean.
Replace bent pedals and cranks. Do not attempt to straighten either.
Ensure pedals are tight at all times (remember tightening is clockwise for right pedal and anti clockwise
for left pedal)
Inspect closely for any stripping of metal around the pedal axle as this could show early signs of a
stripped crank.
This is very important for your safety so replace both pedals and crank set if you are not sure. If you are
not experienced to carry out this work refer to your dealer.
For other qualified technicians refer to our website www.bikesolutions.com.au

Rear wheels
Keep wheel nuts tight and correctly adjusted. Ensure both wheels spin freely with the bearings
correctly adjusted. Keep spokes tight and check the rims are straight and true.
Handlebar and headstem
Make sure the minimum insertion line is not visible and ensure the headstem binder bolt and the stem
expander bolt are tightening securely (20-23Nm 176-202in-lb) Refer page 4 Fig 1
Replace worn grips making sure they are fitted correctly and are tight with finger holes down.
Do not use soap or lubricants as these agents may cause the grips to move even after long periods of
use. Light household contact cement is recommended.
Brake lever
Minor adjustments can be made to the operation and effectiveness of your front brake as shown.
Chain (Coaster and internal geared model 2 x1/8”) (External geared model 1 x 3/32”))
Chain should be inspected regularly for damage or stiff links. Ensure the chain joiner is securely
fastened on coaster and internal geared models.
Lubricate the chain regularly with light machine oil. Use the oil sparingly and wipe off any excess oil.
Seat adjustment.
Ensure the minimum insertion line on the seat post is not visible.
Ensure the seat binder bolt is always tight 20-23Nm(176-202in-lb)
Position the angle of the seat to suit the rider and safe riding conditions and ensure the saddle clamp
bolt is tight 15-19Nm(133-169in-lb)
Align the direction of the saddle for the safety of the rider.
Tyres
Ensure all tyres are inflated according to the pressures indicated on the tyre wall. Frame or foot pump
should be used at all times. Unregulated air pumps must not be used as their volume readings will not
agree with the tricycle volume readings indicated on the tyre wall.
Inspect regularly all tyres to ensure they are correctly seated on the rims.
If a tyre becomes completely flat lift the wheel off the ground before pumping the tyre to correct
pressure to assist in keeping the tyre correctly seated in the rim.
Wet weather riding
All braking effectiveness is compromised during wet weather.
Ensure you allow a longer braking distance to stop.
Increased front brake lever pressure may be required under wet weather conditions.
It is important to take care when applying front brake levers at any time but especially during wet
weather.
Stopping distances can double or even triple in wet conditions.
Adjust your brakes when performance is less efficient than normal.
Avoid skidding and take extra care going downhill.
Ride more slowly in wet conditions than you normally would in dry conditions and avoid sudden stops
or quick manoeuvres.
Remember tricycles due to their particular design, can at times be unstable if turning left or right
abruptly or not planned well in advance.
Take care when riding over metal grates, traffic markers and kerbs.
Visibility is greatly reduced especially in the rain.
Use the same precautions when riding in the rain as you would riding at night.
Refer to the safety instructions listed on page 7.

Road safety information
Riding your tricycle can be a dangerous activity.
Obey the road rules and regulations of your local area.
Wear an approved helmet and fit it correctly every time you ride.
Observe all traffic regulations, red, amber and green lights, one way streets, stop signs, give way signs
and all other directives.
Keep to the correct side of the road in normal traffic directions (always left side of the road in
Australian states and territories).
Give pedestrians the right of way.
Watch for other vehicles when pulling out into traffic.
Watch for other vehicles that may pull out in front of you or turn in front of you. Watch out for sudden
opening of vehicle doors in front of you.
Never carry passengers on your tricycle.
Don’t weave in and out of traffic or swerve from side to side.
Avoid riding over potholes, grates or other hazards.
Always wear light coloured clothing or reflective safety garments. Clothes should be snug fitting but
allow a full range of movement. Loose clothing could get tangled in the wheels or other rotating
mechanisms.
Gloves, long sleeve shirts and pants can reduce injury in the event of an accident.
Always wear suitable footwear. Bare feet or light footwear can be dangerous.
Control your speed at all times, as speed should be relative to the riding terrain and the experience of
the rider.
Reflectors
Reflectors are supplied with your tricycle and should be replaced if damaged.
Ensure they are correctly positioned and clean at all times.
If you have any doubt about the positioning of your reflectors contact the outlet you purchased your
tricycle from.
For other qualified technicians refer to our website www.bikesolutions.com.au
Riding at night
If you are riding after dusk you must have lights installed on the front and rear of your tricycle.
Rechargeable lights are recommended as they can remain on even when you are stationery.
When braking always apply the rear brake first to stop.
Using the front brake only may cause you to become unstable during braking.
In situations that require extra braking use both brakes equally together.
Correct adjustment of the front brake is critical at all times (Refer page 4 fig 2)

Electric front wheel motor assembly.
If a front electric motor is fitted then all documentation will be enclosed for your reference.
Front wheel electric motor manual.
If this manual is, missing then call your dealer for details, before riding.
Tricycles are different from bicycles.
If you are an experienced bicycle rider or previously have ridden bicycles you should be aware of the
different riding experiences of a tricycle.
When turning a bicycle the rider will lean over to compensate for the turn.
It is not possible to do this on a tricycle.
When turning your tricycle it will be more unstable than a two wheel bicycle, so the rider must take
extra care.
