ABOUT THIS MANUAL

This manual was written to help you get the most performance, comfort, enjoyment and safety when riding your new bicycle. It is important for you to understand your new bike. By reading this manual before you go out on your ﬁrst ride, you’ll know how to get the most from your new bicycle. It is also important that your ﬁrst ride on your new bicycle is taken in a controlled environment, away from cars, obstacles, and other cyclists.

GENERAL WARNING

Bicycle riding can be a hazardous activity even under the best of circumstances. Proper maintenance of your bicycle is your responsibility as it helps reduce the risk of injury. This manual contains many “WARNINGS” and “CAUTIONS” concerning the consequences of failure to maintain or inspect your bicycle. Many of the warnings and cautions say, “you may lose control and fall.” Because any fall can result in serious injury or even death, we do not repeat the warning of possible injury or death whenever the risk of falling is mentioned.

Dynacraft does not encourage stunting, trick riding, ramp riding, jumping, aggressive riding, riding on severe terrain, riding in severe climates, riding with heavy loads, riding double, commercial activities; such use is inherently dangerous, can cause serious injury to the rider, and if done it is with the rider’s express and implied assumption of the risk of such use and Dynacraft shall not have any responsibility for any breakdown of the bicycle, its components or rider injuries that occur during such use.

A SPECIAL NOTE FOR PARENTS

It is a tragic fact that most bicycle accidents involve children. As a parent or guardian, you bear the responsibility for the activities and safety of your minor child. Among these responsibilities are to make sure that the bicycle which your child is riding is properly ﬁtted to the child: that it is in good repair and safe operating condition; that the play of young children is supervised by an adult; that you and your child have learned, understand and obey not only the applicable local motor vehicle, bicycle and trafﬁc laws, but also the common sense rules of safe and responsible bicycling. As a parent, you should read this manual before letting your child ride the bicycle. Please make sure that your child always wears an approved bicycle helmet when riding.

NOTE: The illustrations in this manual are used simply to provide examples; the components of your bicycle might differ. In addition, some of the parts shown might be optional and not part of the bicycle’s standard equipment.

The following manual is only a guide to assist you and is not a complete or comprehensive manual of all aspects of maintaining and repairing your bicycle. The bicycle you have purchased is a complex object. We recommend that you consult a bicycle specialist if you have doubts or concerns as to your experience or ability to properly assemble, repair, or maintain your bicycle. You will save time and the convenience of having to go back to the store if you choose to write or call us concerning missing parts, service questions, operating advice, and/or assembly questions.

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 bicycles are much sturdier than those on racing style bicycles.

BEFORE YOU RIDE

STANDOVER HEIGHT

1. Diamond Frame Bicycles

Standover height is the basic element of bike ﬁt (see ﬁgure). It is the distance from the ground to the top tube of the bicycle’s frame at that point where the top of the inseam of your pants is when straddling the bike. To check for correct standover height, straddle the bike while wearing the kind of shoes in which you’ll be riding, and bounce vigorously on your heels. If the inseam touches the frame, the bike is too big for you. Don’t even ride the bike around the block. A bike which you ride only on paved surfaces and never take off-road should give you a minimum standover height clearance of one inch (2.6 cm). A bike that you’ll ride on unpaved surfaces should give you a minimum of three inches (7.5 cm) of standover height clearance.

2. Step-Through Frame Bicycles

Standover height does not apply to bicycles with step-through frames. Instead, the limiting dimension is determined by comparing a diamond frame bike that properly ﬁts and then selecting the step-through bike of the same size.

FRAME WEIGHT LIMIT

There is no American standard for testing the structural weight limits of bicycle frames and for each bike type our limits were determined through lab testing using international standards that seemed reasonable. Not all models were tested. Limits are based on the test results for exemplars of a 20 inch free style bicycle, a 26 inch diamond frame bicycle and a 26 inch dual suspension frame bicycle.

Structural Weight Limit: The maximum weight (rider and cargo) a bike frame can physically support.

Rider Weight: The weight of the rider in riding gear (e.g., jacket, helmet cam, hydration pack, helmet, etc.).

CARGO WEIGHT: The weight of any additional accessories (e.g., panniers, rear racks, saddle bags, handlebar bags, baskets, etc.) not accounted for in Rider Weight.

WEIGHT LIMIT: The maximum structural weight recommendations for our bicycles that are 20 inches or larger are:

WARNING

If your bicycle does not ﬁt properly, you may lose control and fall. If your new bike doesn’t ﬁt, ask your dealer to exchange it before you ride.

BEFORE YOU RIDE

· Free Style 20 inch bicycles: 176 lbs. (80 kg.).

· Diamond frame adult

bicycles up to 26 inches: 275 lbs. (125 kg.).

· Dual suspension frame adult

bicycles up to 26 inches: 275 lbs. (125 kg.).

CORRECT FRAME SIZE

When selecting a new bicycle, the correct choice of frame size is a very important safety consideration.

SAFE SIZING FOR JUVENILE AND SIDEWALK BICYCLES

It is assumed that the bicycle you have bought is sized correctly for the user. Some parents make the mistake of buying a bicycle too large for the intended rider, planning on the child “growing into” it. There should be a minimum of 1 inch clearance above the highest point of the top tube when the child is straddling the bicycle with both feet on the ground (see drawing below).

CAUTION

For safe and comfortable riding there should be a clearance of no less than 1 inch between the inseam 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.

WARNING

If the bicycle is too large the rider cannot reach the pedals easily, or the ground when stopping which may result in loss of control and/or injury.

BEFORE YOU RIDE

RULES OF THE ROAD AND SAFETY TIPS

NOTE: Like any sport, bicycling involves risk of injury and damage. By choosing to ride a bicycle, you assume the responsibility for that risk; not the people who sold you the bike; nor the people who made it; nor the people who distribute it; nor the people who manage or maintain the roads and trails you ride on. YOU. So you need to know - and to practice - the rules of safe and responsible riding.

1. IN THE INTEREST OF SAFER CYCLING,

MAKE SURE YOU READ AND UNDERSTAND YOUR OWNER’S MANUAL. NOTE AND PERFORM PRE RIDE SAFETY CHECKS.

2. NOTICE: Some state and local laws may require

that your bicycle be equipped with a warning device such as a horn or bell and a light if the bicycle is to be ridden after dark.

3. ALWAYS WEAR SHOES when riding a bicycle and AVOID LOOSE FITTING CLOTHES.

4. CHECK YOUR BRAKES FREQUENTLY. THE

ABILITY TO STOP YOUR BICYCLE IS CRITICAL.

Roads are slippery when wet so avoid sharp turns and allow more distance stopping. Caliper brakes may become less efﬁcient when wet. Leaves, loose gravel, and other debris can also effect stopping.

5. ALWAYS RIDE IN THE SAME DIRECTION AS TRAFFIC. Never ride against trafﬁc.

6. STOP AND LOOK BEFORE YOU LEAVE AN ALLEY, DRIVEWAY, OR PARKING LOT. Stop, look to the left,

to the right, and to the left again for trafﬁc. Ride only when it is clear.

7. KEEP TO THE RIGHT. Follow the trafﬁc ﬂow in a

straight line and stay close to the curb. Watch for cars moving in and out of trafﬁc.

8. OBEY ALL TRAFFIC LAWS REGULATIONS. Most

trafﬁc regulations apply to bike riders as well as automobile operators.

9. ALWAYS RIDE ALONE. NEVER CARRY OTHER RIDERS. This is dangerous and makes the bike harder

to control. The bicycles distributed by Dynacraft BSC, Inc. are intended for one rider only.

10. ALWAYS BE ALERT. Be ALERT - pedestrians have

the right of way. Be ALERT - when riding near parked cars - ride far enough away from the cars so that you won’t get hit if someone opens the car door.

LEFT STOP RIGHT

11. USE CAUTION AT ALL INTERSECTIONS AND

STOP SIGNS. STOP AND LOOK BOTH WAYS BEFORE PROCEEDING.

12. USE HAND SIGNALS. Communicate by using hand signals to tell other drivers what you are going to do. Signal 100 feet before turning unless your hand is needed to control the bike (see page 8 for hand signal instructions).

13. HAVE PROPER LIGHTS AND REFLECTORS. IF YOU RIDE AT NIGHT, be sure to have a strong head-

light, a tail light, and a full set of reﬂectors. CHECK

THAT REFLECTORS ARE CLEAN, STRAIGHT, UNBROKEN, AND SECURELY MOUNTED.

14. NEVER CARRY PACKAGES OR OBJECTS WHICH OBSTRUCT VISION.

15. NEVER HITCH RIDES, never hold onto a moving

vehicle while riding.

16. THE KICKSTAND IS DESIGNED TO SUPPORT

THE BICYCLE ONLY, not the bicycle and the rider.

17. AVOID THE FOLLOWING HAZARDS: Drain grates, potholes, soft road edges, gravel, sand, wet leaves, and/or any obstruction in the road. Failure to do so could cause wheel(s) to buckle and result in personal injury to the rider.

18. WET WEATHER RIDING - Riding your bicycle in wet conditions is not recommended. In wet conditions traction and braking power is reduced. Riding in such conditions could result in personal injury.

19. PROPER HELMET USE. A helmet that meets

the CPSC (Consumer Product Safety Commission) standard should always be worn when riding a bicycle. The helmet should ﬁt properly and worn on the crown of the head, not tipped back.

20. USE BIKE LANES when available. Also note that in certain states, cars may use bike lanes when turning.

21. Respect “Bicycles Are Prohibited” signs.

RULES OF THE ROAD AND SAFETY TIPS (continued)

BEFORE YOU RIDE

OFF ROAD SAFETY

We recommend that children not ride on rough terrain unless they are accompanied by an adult. Off road riding on approved trails with appropriate protective equipment can be done with mountain bikes and BMX bikes if you have the skill and experience necessary to maintain control. Whether you call it Aggro, Hucking, Freeride, North Shore, Downhill, Jumping, Stunt Riding, Racing or something else: it is NOT off road riding, it is NOT recommended and if you engage in this sort of extreme, aggressive riding you will get hurt, and you voluntarily assume a greatly increased risk of injury or death. Dynacraft bicycles are not designed for these types of extreme riding.

The variable conditions and hazards of off-road riding require close attention and speciﬁc skills. Start slowly on easier terrain and build up your skills. If your bike has suspension, the increased speed you may develop also increases your risk of losing control and falling. Get to know how to handle your bike safely before trying in-

creased speed or more difﬁcult terrain.

1. Wear safety gear appropriate to the kind of riding you plan to do.

2. Don’t Ride alone in remote areas. Even when riding with others, make sure that someone knows where

you’re going and when you expect to be back.

3. Always take along some kind of identiﬁcation, so that people know who you are in case of an accident;

and take along some cash for food, a cool drink or an emergency phone call.

WARNING

Although many catalogs, advertisements and articles about bicycling depict riders engaged in extreme riding, this activity is extremely dangerous, increases your risk of injury or death, and increases the severity of any injury. Remember that the action depicted is being performed by professionals with many years of training and experience. Even with state-of-the-art protective safety gear, you could be seriously injured or killed when jumping, stunt riding, riding downhill at speed or in competition.

WARNING

Bicycles and bicycle parts have limitations with regard to strength and integrity, and this type of riding can exceed those limitations.

4. Yield right of way to pedestrians and animals. Ride in a way that does not frighten or endanger them, and give them enough room so that their unexpected moves don’t endanger you.

5. Be prepared. If something goes wrong while riding off-road, help may not be close.

6. Do NOT attempt to jump, do stunt riding or race with your bike.

OFF ROAD RESPECT

Obey the local laws regulating where and how you can ride off-road, and respect private property. You may be sharing the trail with others — hikers, equestrians, other cyclists. Respect their rights. Stay on the designated trail. Don’t contribute to erosion by riding in mud or with unnecessary sliding. Don’t disturb the ecosystem by cutting your own trail or shortcut through vegetation or streams. It is your responsibility to minimize your impact on the environment. Leave things as you found them; and always take out everything you brought in.

WET WEATHER RIDING

Under wet conditions, the stopping power of your brakes (as well as the brakes of other vehicles sharing the road) is dramatically reduced and your tires don’t grip nearly as well. This makes it harder to control speed and easier to lose control. Dynacraft does not recommend that you ride under these conditions.

WARNING

Wet weather impairs traction, braking and visibility, both for the bicyclist and for other vehicles sharing the road. The risk of an accident is dramatically increased in wet conditions.

(continued)

BEFORE YOU RIDE

WARNING

Reﬂectors are not a substitute for required lights. Riding at dawn, at dusk, at night or at other times of poor visibility without an adequate bicycle lighting system and without reﬂectors is dangerous and may result in serious injury or death.

WARNING

Do not remove the front or rear reﬂectors or reﬂector brackets from your bicycle. They are an integral part of the bicycle’s safety system. Removing the reﬂectors reduces your visibility to others using the roadway. Being struck by other vehicles may result in serious injury or death.

NIGHT RIDING

Riding a bicycle at night is much more dangerous than riding during the day. A bicyclist is very difﬁcult for motorists and pedestrians to see. Therefore, children should never ride at dawn, at dusk or at night. Adults who choose to accept the greatly increased risk of riding at dawn, at dusk or at night need to take extra care both riding and choosing specialized equipment which helps reduce that risk. Consult your dealer about night riding safety equipment.

PEDALING TECHNIQUE

• Position the ball of your foot on the corner of the pedal.

• When pedaling, ensure your knees are parallel to the bike frame.

• To absorb shock, keep your elbows slightly bent.

• Learn to operate the gears properly (refer to pages 21-23).

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 an accident, teach children good riding skills with an emphasis on safety from an early age.

Children should be made aware of all possible riding hazards and correct riding behavior before they take to the streets.

DO NOT LEAVE IT UP TO TRIAL AND ERROR.

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 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 left, right, and

left again for trafﬁc.

8. If riding downhill, be extra careful. Slow down using the brakes and maintain control of steering.

9. Never take your hands off the handlebars, or your feet off the pedals when riding downhill.

CAUTION

The Consumer Product Safety Commission advises that the riding of small wheel diameter bicycles at excessive speeds can lead to instability and is not recommended.

BEFORE YOU RIDE

CAUTION

Under no circumstances should the seatpost project from the frame beyond its “Minimum Insertion” or “Maximum Extension” mark. If your seatpost projects from the frame beyond these markings, the seatpost or frame may break, which could cause you to lose control and fall. After any saddle adjustment, be sure to tighten the saddle adjusting mechanism properly before riding. A loose saddle clamp or seatpost binder can cause damage to the bicycle or can cause you to loose control and fall. Periodically check to make sure that the saddle adjusting mechanism is properly tightened.

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 it’s lowest point, place the ball of your foot on that pedal. The correct saddle height will allow the knees 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.

Reach

To obtain maximum comfort, the rider should not overextend his or her reach when riding. To adjust the distance, the position of the seat can be altered in relation to the seat pillar.

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.

WARNING

Over tightening the stem bolt or headset assembly may cause damage to the bicycle and/or injury to the rider.

WARNING

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.

CAUTION

Failure to properly tighten the stem wedge 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. If you can twist the stem in relation to the front wheel, turn the bar end extensions in relation to the handlebar, you must tighten the appropriate bolts accordingly.

BEFORE YOU RIDE

SAFETY CHECKLIST

Before every ride, it is important to carry out the following safety checks: (For information and instructions on performing speciﬁc equipment checks, locate the relevant section in the manual using the index on page vii).

1. Brakes

• Ensure front and rear brakes work properly.

• Ensure brake shoe pads are not over worn and are correctly positioned in relation to the rims.

• Ensure brake control cables are lubricated, correctly adjusted, and display no obvious wear.

• Ensure brake control levers are lubricated and tightly secured to the handlebar.

2. Steering

• Ensure handlebar and stem are correctly adjusted and tightened, and allow proper steering.

• Ensure that the handlebars are set correctly in relation to the forks and the direction of travel.

• Check that the head set locking mechanism is properly adjusted and tightened.

• If the bicycle is tted with handlebar end extensions, ensure they are properly positioned

and tightened.

3. Cranks and Pedals

• Ensure pedals are securely tightened to the cranks.

• Ensure cranks are securely tightened to the axle and are not bent.

4. Wheels and Tires

• Ensure tires are inﬂated to within the maximum recommended limit as displayed on the tire sidewall.

• Ensure tires have tread and have no bulges or excessive wear.

• Ensure rims run true and have no obvious wobbles or kinks.

• Ensure all wheel spokes are tight and not broken.

• Check that axle nuts are tight.

5. Chain

• Ensure chain is oiled, clean and runs smoothly.

• Extra care is required in wet or dusty conditions.

• On bicycles equipped with coaster brakes, check for proper chain tension.

6. 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.

7. 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.

9. Accessories

• Ensure that all reﬂectors are properly ﬁtted and not obscured.

• Ensure all other ttings on the bike are properly and securely fastened, and functioning.

• Ensure the rider is wearing a helmet.

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.

BEFORE YOU RIDE

HELMETS

Local laws of most places require a helmet, and common sense requires them in other places where it is not the law. It is strongly advised that a properly ﬁtting, CSPC approved, 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 properly ﬁtted helmet.

The correct helmet should:

• be comfortable

• be lightweight

• have good ventilation

• t correctly

REFLECTORS

Your bicycle is supplied with one front (white), one rear (red), two wheel (white), and two pedal (orange) reﬂectors. These are an important safety and legal requirement, and should remain securely ﬁtted and in good, clean conditions at all times. Periodically, inspect all reﬂectors, brackets, and mounting hardware for signs of wear or damage. Replace immediately if damage is found. Some bicycles will require you to install your reﬂectors onto your bicycle.

WARNING

Always wear a properly ﬁtted helmet when riding a bicycle. Falling off your bicycle without a helmet can cause serious injury or death. Many states require speciﬁc safety devices. It is your responsibility to familiarize yourself with the laws of the state where you ride and comply with all applicable laws, including properly equipping yourself and your bike as the law requires. Reﬂectors are important safety devices which are designed as an integral part of your bicycle. Federal regulations require most types of bicycles to be equipped with front, rear, wheel, and pedal reﬂectors. These reﬂectors are designed to pick up and reﬂect street lights and car lights in a way that helps you to be seen and recognized as a moving bicyclist. Check reﬂectors and their mounting brackets regularly to make sure they are clean, straight, unbroken, and securely mounted. Replace damaged reﬂectors and straighten or tighten any that are bent or loose.

Please refer to the following section for instructions on all types of bicycle reﬂectors.

NOTE: CPSC Regulations do not require reﬂectors on 10”, 12” and 16” Sidewalk Bicycles - We recommend, however, that you attach reﬂectors for the protection of the rider. These types of bicycles should be operated during daylight hours only, on a smooth, paved surface such as a sidewalk, under the direct supervision of an adult. These bicycles should never be ridden in the street, on an incline, or on rough terrain. Under no circumstances should these types of bicycles be operated at speeds that would make it difﬁcult to control, nor should it be raced or used for stunting, jumping, motocross, or off-road use or other activities not normally associated with a Sidewalk Bicycle.

WHEEL REFLECTORS

The wheel reﬂectors should come already attached to the spokes of both the front and rear wheels. To attach reﬂector to the wheel, ﬁt the groove in the reﬂector to a spoke that matches the groove. The reﬂector should be mounted across from the valve stem and as close to the rim as possible. The reﬂector should ﬁt ﬁrmly between a single spoke on one side and two spokes on the other. Use the supplied clip (with two locking prongs), ﬁt the clip over the spoke and into the hole and press until the locking prongs “click” into place. Be sure to ﬁt reﬂectors to both wheels.

FRONT MOUNT REFLECTOR BRACKET ASSEMBLY

Slide reﬂector over bracket as shown in diagram and ensure that the tab clicks into the top hole of the bracket. Insert one washer onto the hex bolt and insert hex bolt through the reﬂector bracket and then through the fork. Next, insert a second washer onto the bolt and thread a hex nut onto the bolt behind the fork. Tighten bolts until snug, making sure the reﬂector is in an upright position.

BEFORE YOU RIDE

SEAT AND HANDLEBAR MOUNTING REFLECTORS

Slide reﬂector over bracket (shown on page 19) and ensure that the tab clicks into the top hole of the bracket. Next, remove the clamp screw and open the clamping reﬂector bracket. Place clamping reﬂector bracket around the handlebar or seatpost. If the clamp is too loose, insert the shim inside of the clamp. Tighten the clamp screw to hold reﬂector assembly in place. Finally, adjust the reﬂector such that it is upright and facing away from the bike.

SEATPOST MOUNT REFLECTOR BRACKET ASSEMBLY

Slide reﬂector over bracket as shown in diagram below and ensure that the tab clicks into the top hole of the bracket. Insert one washer onto the hex bolt and insert hex bolt through the reﬂector bracket and around the seatpost. Tighten bolts until snug, making sure the reﬂector is in an upright position. See diagram below.

PEDAL REFLECTORS

Pedal reﬂectors are required by federal law. Maintain them and replace any that are missing.

GEARS - HOW TO OPERATE

Derailleur Gears

Most multi-speed bicycles today are equipped with what are known as derailleur gears. They operate using a system of levers and mechanisms to move the drive chain between different sized driving gears or cogs. The purpose of gears is to let you maintain a constant, steady pedaling pace under varying conditions. This means your riding will be less tiring without unnecessary straining up hills or fast pedaling down hill. Bicycles come with a variety of gear conﬁgurations from 5 to 27 speeds. A 5-6 speed bicycle will have a single front chain-wheel, a rear derailleur, and 5 or 6 cogs on the rear hub. Bicycles with more gears will also have a front derailleur, a front chainwheel with 2-3 cogs, and up to 7 cogs on the rear hub.

Operating Principles

No matter how many gears, the operating principles are the same. The front derailleur is operated by the left shift lever and the rear derailleur by the right. To operate, you must be pedaling forward. You can not shift derailleur gears when you are stopped or when pedaling backwards. Before shifting, ease up on your pedaling pressure. For a smooth gear change when approaching a hill, shift to a lower gear BEFORE your pedaling speed slow down too much. When coming to a stop, shift to a lower gear ﬁrst so it will be easier when you start riding again. If, after selecting a new gear position, you hear a slight rubbing noise from the front or rear gears, gently adjust the appropriate shifter using the barrel adjusters until the noise goes away. For optimal performance and extended chain life, it is recommended that you avoid using the extreme combinations of gear positions (diagram page 22) for extended periods.

CAUTION

Children under age 9 should only ride single speed bicycles as they do not have capability to use shifters.

Hand Grip Shifters

Many bicycles are now being equipped with a shifting mechanism that is built into the handlebar grips and does not make use of separate levers. The shifting is built into the inside part of the grip that allows the thumb and index ﬁnger around. To select a lower gear, twist the grip towards you to engage a larger rear cog. You can shift one gear at a time by moving the shifter one click, or through multiple gears by continuing twisting. By twisting the left shifter forward or away from you, a smaller chainwheel can be selected. To select a higher gear, twist the right shifter forward or away from you to engage a smaller rear cog. To engage a larger front chainwheel, twist the left shifter towards you.

NOTE: Some bicycles may be equipped with a rear derailleur mechanism that works in reverse to the direction above.
