PARTS IDENTIFICATION
Mountain Bicycles . Mountain bicycles are designed to give maximum comfort over a wide variety of road surfaces. The
wider handlebars and convenient shift lever position make them very easy to control. Wider rims and tires give them a softer
ride with more traction on rough surfaces. The frame and fork on mountain style bicycles are generally much sturdier than those on
racing style bicycles.

05
CORRECT FRAME SIZE
When selecting a new bicycle, the correct choice of frame size is a very important safety consideration. Most full sized
bicycles come in a range of frame sizes. These sizes usually refer to the distance between the center of the bottom bracket
and the top of the frame seat tube.
For safe and comfortable riding there should be clearance of no less than 1 - 2 inches between
the groin area of the intended rider and the top tube of the bicycle frame, while the rider straddles the
bicycle with both feet flat on the ground.
The ideal clearance will vary between types of bicycles and rider preference. This makes straddling the frame when off the
saddle easier and safer in situations such as sudden traffic stops. Women can use a men’s style bicycle to determine the
correct size women’s model.
The following chart and diagram will help you make the correct choice. Rider leg length refers to approximate pant inseam.

06
RIDING POSITION
Saddle Height
In order to obtain the most comfortable riding position and offer the
best possible pedaling efficiency, the seat height should be set
correctly in relation to the rider’s leg length. The correct saddle height
should not allow leg strain from over-extension, and the hips should
not rock from side to side when pedaling. While sitting on the bicycle
with one pedal at its lowest point, place the ball of your foot on that
pedal. The correct saddle height will allow the knee to be slightly
bent in this position. If the rider then places the heel of that foot on
the pedal, the leg should be almost straight.
Under no circumstances should the seat post project
from the frame beyond its “Minimum Insertion” or
“Maximum Extension” mark. If your seat post projects
from the frame beyond these markings, the seat post
or frame may break, which could cause you to lose
control and fall. Prior to your first ride, be sure to tighten the
saddle adjusting mechanism properly. A loose saddle clamp or
seat post binder can cause damage to the bicycle or can cause
you to lose control and fall. Periodically check to make sure that
the saddle adjusting mechanism is properly tightened.
Reach
To obtain maximum comfort, the rider should not overextend his or her
reach when riding.
To adjust this distance, the position of the seat can be altered in
relation to the seat pillar.

07
Handlebar Height
Maximum comfort is usually obtained when the handlebar height is
equal to the height of the seat. You may wish to try different heights
to find the most comfortable position.
Threadless headsets and clamp-on stems are not adjustable.
The stem’s “Minimum Insertion” mark must not be visible above the top of the headset.
If the stem is extended beyond this mark, the stem may break or damage the fork’s
steerer tube, which could cause you to lose control and fall.
Failure to properly tighten the stem binder bolt, the handlebar binder bolt, or the bar
end extension clamping bolts may compromise steering action, which could cause
you to lose control and fall. Place the front wheel of the bicycle between your legs and
attempt to twist the handlebar/stem assembly using a reasonable amount of force. If
you can twist the stem in relation to the front wheel, turn the handlebars in relation to
the stem, or turn the bar end extensions in relation to the handlebar, you must tighten
the appropriate bolts accordingly.

- Check that the headset locking mechanism is properly adjusted and tightened.
- If the bicycle is fitted with handlebar end extensions, ensure they are properly positioned and tightened.

09
4. Chain
- Ensure chain is oiled, clean and runs smoothly.
- Extra care is required in wet or dusty conditions.
5. Bearings
- Ensure all bearings are lubricated, run freely and display no excess movement, grinding or rattling.
- Check headset, wheel bearings, pedal bearings and bottom bracket bearings.
6. Cranks and Pedals
- Ensure pedals are securely tightened to the cranks.
- Ensure cranks are securely tightened to the axle and are not bent.
7. Derailleurs
- Check that front and rear mechanisms are adjusted and function properly.
- Ensure control levers are securely attached.
- Ensure derailleurs, shift levers and control cables are properly lubricated.
8. Frame and Fork
- Check that the frame and fork are not bent or broken.
- If either are bent or broken, they should be replaced.
9. Accessories
- Ensure that all reflectors are properly fitted and not obscured.
- Ensure all other fittings on the bike are properly and securely fastened, and functioning.
- Ensure the rider is wearing a helmet.

10
Helmets
It is strongly advised that a properly fitting, ANSI or SNELL, or CSA
certified, bicycle safety helmet be worn at all times when riding your
bicycle. In addition, if you are carrying a passenger in a child safety
seat, they must also be wearing a helmet.
The correct helmet should:
- be comfortable
- be lightweight
- have good ventilation
- fit correctly
- cover forehead
Always wear a properly fitted helmet which covers the forehead when riding a bicycle. Many provinces
require specific safety devices. It is your responsibility to familiarize yourself with the laws of the province
where you ride and to comply with all applicable laws, including properly equipping yourself and your bike
as the law requires.

11
Reflectors
Your bicycle is supplied with one front (white), one rear (red), two wheel (white), and four pedal (orange)
reflectors. (Please Note: Sidewalk bikes, 12” and under, may not have reflectors.) These are an important safety and legal
requirement, and should remain securely fitted and in good, clean condition at all times. Periodically, inspect all reflectors,
brackets and mounting hardware for signs of wear or damage. Replace immediately if damage is found.

RIDING SAFELY
General Rules
When riding obey the same road laws as all other road vehicles, including giving way to
pedestrians, and stopping at red lights and stop signs.
For further information, contact the Road Traffic Authority in your province.
Ride predictably and in a straight line. Never ride against traffic.
Use correct hand signals to indicate turning or stopping.
Ride defensively. To other road users, you may be hard to see.
Concentrate on the path ahead. Avoid pot holes, gravel, wet road markings, oil, curbs, speed
bumps, drain grates and other obstacles.
Cross train tracks at a 90 degree angle or walk your bicycle across.
Expect the unexpected such as opening car doors or cars backing out of concealed driveways.
Be extra careful at intersections and when preparing to pass other vehicles.
Familiarize yourself with all the bicycle's features. Practice gear shifts, braking, and the use of
toe clips and straps, if fitted.
If you are wearing loose pants, use leg clips or elastic bands to prevent them from being caught
in the chain. Wear proper riding attire and avoid open toe shoes.
Don't carry packages or passengers that will interfere with your visibility or control of the bicycle.
Don't use items that may restrict your hearing.
Do not lock up the brakes. When braking, always apply the rear brake first, then the front. The
front brake is more powerful and if it is not correctly applied, you may lose control and fall.
Maintain a comfortable stopping distance from all other riders, vehicles and objects.
Safe braking distances and forces are subject to the prevailing weather conditions.

13
Wet Weather
IT IS RECOMMENDED TO NOT RIDE IN WET WEATHER
- In wet weather you need to take extra care.
- Brake earlier, you will take a longer distance to stop.
- Decrease your riding speed, avoid sudden braking and take corners with additional
caution.
- Be more visible on the road.
- Wear reflective clothing and use safety lights.
- Pot holes and slippery surfaces such as line markings and train tracks all become more
hazardous when wet.
Night Riding
- Ensure bicycle is equipped with a full set of correctly positioned and clean reflectors.
- Use a properly functioning lighting set comprising of a white front lamp and a red rear lamp.
- If using battery powered lights, make sure batteries are well charged.
- Some rear lights available have a flashing mechanism which enhances visibility.
- Wear reflective and light colored clothing.
- Ride at night only if necessary. Slow down and use familiar roads with street lighting, if possible.
Pedaling Technique
- Position the ball of your foot on the center of the pedal.
- When pedaling, ensure your knees are parallel to the bicycle frame.
- To absorb shock, keep your elbows slightly bent.
- Learn to operate the gears properly.
IT IS RECOMMENDED TO NOT RIDE AT NIGHT

14
Hill Technique
- Gear down before a climb and continue gearing down as required to maintain pedaling speed.
- If you reach the lowest gear and are struggling, stand up on your pedals. You will then obtain more power from
each pedal revolution.
- On the descent, use the high gears to avoid rapid pedaling.
- Do not exceed a comfortable speed; maintain control and take additional care.
Cornering Technique
Brake slightly before cornering and prepare to lean your body into the corner. Maintain the inside pedal at the 12 o'clock
position and slightly point the inside knee in the direction you are turning. Keep the other leg straight, don't pedal through
fast or tight corners.
Rules for Children
To avoid accidents, teach children good riding skills with an emphasis on safety from an early age. Children should be super-
vised by an adult.
1. Always wear a properly fitted helmet.
2. Do not play in driveways or the road.
3. Do not ride on busy streets.
4. Do not ride at night.
5. Obey all the traffic laws, especially stop signs and red lights.
6. Be aware of other road vehicles behind and nearby.
7. Before entering a street: Stop, look right, left, and right again for traffic. If there's no traffic, proceed into the roadway.
8. If riding downhill, be extra careful. Slow down using the brakes and maintain control of the steering.
9. Never take your hands off the handlebars, or your feet off the pedals when riding downhill.

DERAILLEUR GEARED BICYCLES
Includes 20", 24” and 26" Wheel Mountain Bikes
Assembly is the same for men’s
and women’s bikes.
Getting Started
Open the carton from the top and remove the bicycle. Remove the
straps and protective wrapping from the bicycle. Inspect the bicycle
and all accessories and parts for possible shortages. It is recommended
that the threads and all moving parts in the parts package be lubricated
prior to installation. Do not discard packing materials until assembly is
complete to insure that no required parts are accidentally discarded.
Assemble your bicycle following the steps that pertain to your model.
Note: Your bicycle may be equipped with different style components
than the ones illustrated.
Handlebars
Remove the protective cap from the handlebar stem wedge and loosen
the Allen key bolt using the 6mm Allen key. Some models may use a
13mm hexagonal bolt instead of an Allen key bolt. Place the handlebar
stem into the top of the head tube, ensuring that all cables are free of
tangles. Tighten the stem bolt observing the minimum insertion mark and
checking that the forks and the handlebars are facing forward. Check
the headset for smooth rotation and that the top nut is secured tightly.
Loosen the 6mm Binder Bolt and rotate the handlebar forward so the
levers are at a 45 degree angle below the handlebar. Retighten the
Binder Bolt to ensure the handlebar does not rotate in the stem.
