When you send the handover report to G.B.S. Global Bike Service Ltd.

your BMW bicycle will be registered. We shall be pleased to con󷴲rm the

purchase of your BMW bicycle as soon as it will be registered.

To 󷴲nd more 󷴲lms, downloads and information on BMW bikes as well as

further BMW lifestyle products, please visit us at www.bmw-shop.com.

In purchasing this bicycle you have chosen a product of high quality and technology. Each component of your new bicycle has been designed, manufactured and assembled with great care and expertise. Your BMW

partner gave the bicycle its 󷴲nal assembly and performed a function

check to guarantee proper operation. You can now set off to enjoy your new bicycle feeling safe and secure.

This manual contains a wealth of information on the proper use of your bicycle, its maintenance and operation as well as interesting details about bicycle design and engineering. Please read these instructions thoroughly. We are sure that even if you have been cycling all your life

you will 󷴲nd it worthwhile. Bicycle technology has developed at a rapid

pace during recent years. Therefore, before setting off on your new bicycle, be sure to read at least the chapter “Before Your FIRST Ride“.

To have as much fun as possible during cycling, be sure to carry out the minimum functional check described in chapter “Before EVERY Ride” before setting off. This manual cannot teach you the skills of a bicycle mechanic. Even a manual as big as an encyclopaedia could not describe every possible combination of available bicycles and components. It therefore focuses on your newly purchased bicycle and standard components providing important information and warnings.

When doing maintenance or repair work, be aware that the detailed instructions provided in your manual only refer to these bicycles.

The information included here is not applicable to any other bicycle. As bicycles come in a wide variety of designs with frequent model changes, the routines described may not be complete. In addition, please observe the instructions of the component suppliers that you have received from your BMW partner.

Be aware that these instructions may require further explanation, depending on the experience and/or skills of the person doing the work. For some jobs you may require additional (special) tools or supplementary instructions.

For your own safety, never do work on your bicycle unless you feel absolutely sure about it. If you are in doubt or if you have any questions, please contact your BMW partner!

Before you set off, let us point out a few things that are very important to every cyclist: Never ride without a properly adjusted helmet and without glasses and take care to always wear suitable clothing. At least you

should wear straight cut trousers and shoes 󷴲tting the pedal system. Always ride carefully on public roads and observe the traf󷴲c rules so as

not to endanger yourself or others.

This manual cannot teach you how to ride. Please be aware that cycling is a hazardous activity that requires the rider to stay in control of his or her bicycle at all times.

Like any sport, cycling involves the risk of injury. Keep this in mind. When you decide to ride a bicycle you need to accept the risk inherent to cycling. Please note that on a bicycle you have no protection technology around you (e.g. bodywork, airbag) like you have in a car. Therefore,

always ride carefully and do respect the other traf󷴲c participants. Never ride under the in󷴳uence of drugs, medication, alcohol or when you are

tired. Do not ride with a second person on your bicycle and always ride with your hands on the handlebars.

Obser ve the legal regulations concerning off-road cycling. These regulations may differ in each country. Please respect nature when riding off-road. Only use your bicycle on signposted, well-maintained trails and hard-surface roads.

First we would like to familiarise you with the various components used

on your bicycle. Please unfold the cover of this manual. Here you will 󷴲nd

the diagrams of three bicycles showing all the essential components. Leave the page unfolded as you read so that you can easily locate the components as they are referred to in the text.

Have a nice cycle trip! Your BMW Group team

IMPRINT.

1.1 General Notes on this Manual.

The technology of today’s bicycles has become very complex. As there is a vast range of bicycle components, this manual focuses on the most important parts including general features. Therefore, be sure to observe the additional adjustment and/or maintenance instructions of the respective component manufacturers that you have received from your BMW partner together with this manual.

If you intend to do any maintenance or repair work by yourself, you should keep in mind that today’s bicycle technology requires a considerable amount of know-how as well as special tools (a), such as e.g. a torque wrench (b). Have your bicycle ser viced by your BMW partner to be on the safe side.

The following information refers to your bicycle by using the speci󷴲c

technical terms. Therefore, make yourself familiar with your bicycle.

Please unfold the front cover of this manual. You will 󷴲nd the diagrams

of three bicycles showing the components found on your bicycle. Leave the page unfolded as you read so that you can easily locate the components as they are referred to in the text.

The table of contents will quickly lead you to the part you are interested in.

This symbol signi󹞬es a warning that you should strictly observe

in view of your own safety and that of others and to prevent your BMW bicycle from damage.

This symbol provides you with information or details on how to make the most of your BMW bicycle.

Please note that the aforementioned consequences will not be repeated each time the symbols appear in the manual.

This manual does not help you to assemble a bicycle from individual parts, to repair it or to make a partly assembled bicycle ready-for-use!

Technical details in the text and illustrations of this manual are subject to change.

This manual complies with the requirements of the European standards EN 14764 and EN 14766.

In addition, please observe the included instructions of the component manufacturers. This manual is subject to European law. If delivered to countries outside Europe, supplementary information has to be provided by the bicycle manufacturer.

This manual does not provide any information on frames and components made of carbon! Misuse of carbon parts may result in material failure, breakage and accidents. In case you

want to 󹞬t your bicycle with carbon components, please read

the instructions included with these components thoroughly! If you are in doubt or if you have any questions, please contact your BMW partner!

1.2 Before Your First Ride.

1. Be sure to use your bicycle only for its intended purpose, as it may

otherwise not stand up to the stress and fail! Risk of accident!

For more information on the intended use read chapter “Intended

Use”.

2. The maximum overall weight (including rider, baggage and bike) your

bicycle is designed for is speci󷴲ed in chapter “Intended Use”.

3. Are you familiar with the brakes (a)? Check whether the lever of the

front brake is in the position you are used to (right or left). If it is not, you will need to learn to get used to it, as inadvertent use of the front brake can throw you off your bicycle. Or ask your BMW partner to switch the brake levers.

Your new bicycle is equipped with modern brakes (b) which may be

far more powerful than those you were used to so far! Be sure to 󷴲rst

practise using the brakes on a level, non-slip surface off public roads!

For more information see chapter “Brake System”.

Note that the distance you need to stop your bicycle increases, while riding with your hands on bar ends (c). The brake levers are not always within easy reach.

4. Are you familiar with the type and functioning of the gears? If not,

make yourself familiar with the gears in a place free of traf󷴲c.

For more information see chapter “Drive System”.

5. Are both saddle and handlebars properly adjusted? Check whether your toes reach to the 󷴳oor when you are sitting on the saddle (d). Your BMW partner will be pleased to help you if you are not happy with your seating position.

For more information see chapter “Adjusting the Bicycle to the

Rider”.

Make particularly sure there is enough space between your crotch and the top tube so that you do not hurt yourself, if you have to get off your bicycle quickly.

6. If your bicycle is equipped with clipless or step-in pedals (a), do not set off until you have practised engaging and disengaging the shoes from the pedals while stationary (b).

For more information see chapter “Proper Cycling Equipment”.

Be sure to also read the operating instructions for the pedals delivered by your BMW partner.

A lack of practice when using clipless pedals or too much spring tension in the mechanism can lead to a very 󹞬rm connection, from which you cannot quickly step out! Risk of accident!

7. If you have bought a suspension bicycle, you should ask your BMW partner to adjust the suspension mechanism to your needs before delivery. If you have bought it at ww w.bmw-shop.com, ask at a bicycle specialist shop of your trust to do this job. Improperly adjusted suspension components are liable to malfunction or damage. In any case they will impair the performance of your bicycle as well as your safety whilst riding.

For more information see chapters “Suspension Forks” and

“Rear Shock”. Further notes regarding full suspension bicycles and forks may be enclosed with this manual.

1.3 Before Every Ride.

Your bicycle has undergone numerous tests during production and a

󷴲nal check has been carried out by your BMW partner. Nevertheless,

be sure to check the following points to exclude any malfunctioning that may be due to the transport of your bicycle or to work a third person may have performed on your bicycle before delivery:

1. Are the quick-release levers of the front and rear wheel properly closed and the bolts of the seat post and other components correctly tightened (a)? For more information see chapter “How to Use Quick-Releases and Thru Axles”.

Improperly closed quick-releases can cause bicycle components to come loose. Risk of accident!

2. Are the tyres in good condition and do they have suf󷴲cient pressure?

Make a “thumb test“ (b).

For more information see chapter “Wheels and Tyres”.

3. Spin the wheels to check whether the rims are true. Watch the gap between rim and brake pad or, in the case of disc brakes, between frame and rim or tyre. Untrue rims can be an indication of tyres with ruptured sides or broken axles or spokes.

For more information see chapter “Wheels and Tyres”.

4. Test the brakes while stationary by 󷴲rmly pulling the brake levers

towards the handlebars (c). The brake pads of rim brakes must hit the rim with their entire surface without touching the tyre. You should not be able to pull the lever all the way to the handlebars! The same applies to the brake levers of disc brakes. You should not be able to pull

them all the way to the handlebars! Make sure there is no brake 󷴳uid

leakage. Also check the thickness of the brake pads.

For more information see chapter “Brake System”.

5. Let your bicycle bounce on the ground from a small height. If there is any rattling, check where it comes from. Check the bearings and bolts, if necessary.

6. If you want to ride on public roads, make sure your bicycle is equipped according to the regulations of your countr y (d). Riding without lights and re󷴳ectors in dark or dim conditions is very dangerous, because other road users will see you too late or not at all. A set of lights that corresponds to the regulations is a must on public roads. Turn on the lights as soon as dusk sets in.

For more information see chapter “Legal Requirements for Rid-

ing on Public Roads“.

7. If your bicycle has suspension, check the frame: Press down on your bicycle and see whether the spring elements retract and extend as usual (a+b).

For more information see chapters “Suspension Forks” and

“Rear Shock”. Further notes regarding full suspension bicycles and forks may be enclosed with this manual.

8. If your bicycle has a kickstand, make sure it is fully raised before you set off. Risk of accident!

Do not use your bicycle, if it fails on one of these points! Riding a defective bicycle can result in serious accidents! If you are in doubt or if you have any questions, please contact your BMW partner!

During use your bicycle is undergoing stress resulting from the surface of the road and through the rider’s action. Due to these dynamic loads, the different parts of your bicycle react with wear and fatigue. Please check your bicycle regularly for wear marks, scratches (c), bent parts, colour changes and any indication of cracking. Parts which have reached the end of their lifespan may break without previous warning. Let your BMW partner maintain and service your bicycle regularly and in cases of doubt it is always best to replace parts.

Do not forget to take a high quality D- or chain lock (d) with you on your ride. The only way to effectively protect your bicycle against theft is to lock it to an immovable object.

1.4 After an Accident.

1. Check whether the wheels are still 󷴲rmly 󷴲xed in the drop-outs and

whether the rims are still centred with respect to the frame or fork. Spin the wheels. If the width of the gap changes markedly and you cannot true the rim where you are, you will need to open the rim brakes a little so that the rim can run between the brake pads without touching them. Caution: This will reduce the braking performance.

For more information see chapters “Brake System” and “Wheels

and Tyres”.

2. Check that handlebars and stem are neither bent nor broken and that

they are level and upright. Make sure the stem is 󷴲rmly 󷴲xed on the

fork by taking the front wheel between your knees and by trying to twist the handlebars relative to the front wheel (a). Brie󷴳y lean on the

brake levers to make sure the handlebars are 󷴲rmly 󷴲xed in the stem.

For more information see chapters “Adjusting the Bicycle to the

Rider” and “Headset”.

3. Check whether the chain still runs on the chainrings and sprockets (b). If your bicycle fell over on the chain side, verify the proper functioning of the gears. Ask somebody to lift the bicycle by the saddle and gently shift through all the gears. Pay particular attention when shifting to the small gears, making sure the rear derailleur does not get too close to the spokes as the chain climbs onto the larger sprockets (c). If the rear derailleur or the drop-outs are bent, this can cause the rear derailleur to collide with the spokes and result in an

accident! This in turn can destroy the rear derailleur, the rear wheel or the frame. Check the front derailleur, as a damaged gear changer can throw off the chain, thus interrupting the power train of the bicycle (see chapter “Drive System”).

4. Make sure the saddle is not twisted using the top tube or the bottom bracket shell as a reference (d).

5. Lift your bicycle up a few centimetres and let it bounce onto the ground. If this causes any sort of noise, search for loosened bolts or components.

6. Finally, take a good look at the whole bicycle to detect any deformations, discolourations or cracks.

Only if your bicycle passed these checks without any problems should you ride back very carefully, taking the shortest possible route. Do not brake hard or accelerate and do not ride your bicycle out of the saddle. If you are in doubt about the performance of your bicycle, have yourself picked up by car, instead of taking any risk. Back home you need to check your bicycle thoroughly. If you are in doubt or if you have any questions, please contact your BMW partner!

Bent parts made of aluminium must not be repaired, i.e. straightened, as the risk of breakage would still remain. This applies in particular to forks, handlebars, stems, cranksets and pedals. Be sure to replace them as a precaution.

1.5 How to Use Quick-Releases and Thru Axles.

1.5.1 Quick-Releases.

Your bicycle is 󷴲tted with quick-releases to ensure fast adjustments,

assembly and disassembly. Be sure to check whether all quick-releases are tight before you set off on your bicycle. Quick-releases should be handled with great care, as they directly af fect your safety.

Practise the use of quick-releases to avoid any accidents.

Quick-release mechanisms essentially consist of two operative elements:

1. The hand lever on one side of the hub which creates a clamping force

via a cam when you close it (a).

2. The tightening nut on the other side of the hub with which the initial

tension on the threaded rod is set.

Make sure the levers of both quick-releases at the front and rear wheel are always on the side opposite to the chain. This will help you to avoid mounting the front wheel the wrong way round. By contrast, with disc brakes the front quick-release is usually mounted with its lever to the right.

Never ride a bicycle without having 󹞬rst checked whether the

wheels are securely fastened! A wheel that comes loose whilst riding will throw you off your bicycle!

If your bicycle is equipped with quick-releases, be sure to lock the frame to an immovable object together with the wheels when you leave it outside.

How to Fasten Components Securely.

Open the quick-release. The marking “Open“ on the lever should become visible now (b).

Do not touch the rotor directly after stopping – you may burn

your 󹞬ngers! Always let the rotor cool down before opening the

quick-releases!

Move the lever back, as if to close it. Now you should be able to read ”Close“ on the outside of the lever. When you start closing the lever you should feel virtually no resistance with your hand until the lever is at right angle to the frame/fork.

Over the second half of its travel the resistance you feel should increase

signi󷴲cantly. Towards the end of its travel you should need very much

strength to close the lever. Use the ball of your thumb to push it in all the

way while your 󷴲ngers pull on an immovable part, such as the fork or the

rear stay (c), but not on a rotor or spoke.

In its end position, the lever should be parallel to the bicycle, i.e. it should not stick out to the side ((d) p. 12). The lever should lie close to the frame or the fork so that it cannot be opened accidentally.

To check whether the lever is securely locked apply pressure to the end of the hand lever and try to turn it while it is closed. If you can turn the lever around, open it and increase the initial tension. Screw the tightening nut on the opposite side clockwise by half a turn. Close the lever and check it again for tightness.

Finally, lift the bicycle a few centimetres so that the wheel no longer touches the ground and hit the tyre from above (a). If it is properly

fastened, the wheel will remain 󷴲rmly 󷴲xed in the drop-outs of the frame

without any rattling noise.

If your seat post is equipped with a quick-release mechanism, check

whether the saddle is 󷴲rmly 󷴲xed by trying to twist it relative to the frame

(b).

With insuf󹞬ciently closed quick-releases and thru axles the

wheels can come loose, thus creating a serious risk of accident!

If your bicycle is equipped with quick-releases (c), be sure to lock the frame to an immovable object together with the wheels when you leave it outside.

As an anti-theft measure you can replace the quick-releases by special locks (d). They can only be opened and closed with a special, coded key or an Allen key. If you are in doubt or if you have any questions, please contact a bicycle specialist shop of your trust!

With the DT Swiss RWS system the clamping force is not created via a cam, but by tightening a bolted connection with a lever.

Tighten the system by turning the lever clockwise while holding the clamping nut tight.

Depending on frame or fork the lever may touch either frame or fork during tightening. If it does, pull out the lever, turn it back, let it engage again before retightening.

In its end position, the lever should be parallel to the bicycle, i.e. it should not stick out. The lever should lie close to the frame or the fork so that it cannot be opened accidentally.

Finally, lift the bicycle a few centimetres so that the wheel no longer touches the ground and hit the tyre from above. If it is properly fastened,

the wheel will remain 󷴲rmly 󷴲xed in the drop-outs of the frame without

any rattling noise.

1.5.2 Thru Axles.

Thru axles are mounted when the bicycle has to withstand high stress occurring e.g. during freeriding, downhill riding etc. or jumps. They provide suspension forks with a suitable stiffness.

Before mounting or replacing a fork/wheel combination, be sure to read the operating instructions of the respective sus-

pension fork or wheel manufacturer 󹞬rst.

Notes on How to Mount Thru Axle Wheels.

There is a wide range of thru axle systems available now. Some systems are tightened with quick-releases. Other systems may require special tools for assembly or disassembly (a+b).

Be sure to read the respective manual before doing any assembly work.

If you are in doubt or if you have any questions, please contact a bicycle specialist shop of your trust!

Improperly mounted wheels may throw you off your bicycle or result in serious accidents!

Check the fastening after one to two hours in use and then ever y 20 hours of use.

For the removal of the front wheel you may need tools (c) depending on fork manufacturer and thru axle system. To remove the wheel, loosen the axle support at the fork and remove the axle completely from the hub.

To remount the front wheel proceed in the reverse order. Make sure all bolts/quick-release systems are tightened properly.

To mount the axle use only the tools recommended by the

manufacturer. Make it a rule to use a torque wrench (d). Tighten

carefully by approaching the prescribed maximum torque in

small steps (0.5 Nm increments) whilst constantly checking the

proper 󹞬t of the component. Never exceed the maximum tightening torque indicated by the manufacturer! A too tight 󹞬xing of the axle can damage the axle or the fork leg.

Check the bolts after one to two hours of use and then every 20 hours.

2 INTENDED USE.

2.1 General Overview.

Please follow the tips provided in section “Safe Cycling on Public Roads” in chapter “Useful Tips for Cycling in Town and Country”.

2.1.1 Cruise Bike (a+b).

Due to their design and equipment this type of bicycle is not intended to be used on public roads. If you intend to use this type of bicycle on pub-

3 LEGAL REQUIREMENTS FOR

RIDING ON PUBLIC ROADS.

If you use your bicycle for riding on public roads, it has to be equipped according to the regulations of your country.

Pay particular attention to your bicycle being equipped with the prescribed lighting set (a+b) and re󷴳ectors. Contact your BMW partner or a bicycle specialist shop of your trust and ask for information about the regulations in force in your country. Make yourself familiar with the road

traf󷴲c regulations for riding on public roads and off-road.

4 USEFUL TIPS FOR CYCLING IN

TOWN AND COUNTRY.

4.1 Safe Cycling on Public Roads.

Keep in mind your bicycle is not only sports equipment (a), but also an eco-friendly means of transport. Many cities and villages are very committed to improving cycling conditions by creating cycle lanes and by allowing cyclists to ride the wrong way up one-way streets. When you set off on your bicycle always be aware that you are among the vulnerable road user groups. Bicycles do not have airbags, safety belts or a crush zone. A collision may have serious long-term negative consequences to your health. For this reason it is very important for you to ride with caution and try to avoid dangerous situations beforehand.

This manual cannot teach you how to ride or make you familiar with all rules of conduct on public roads. For more information please contact a road safety organization in your country, a bicycle club or comparable organizations.

Tips on how to ride safely on public roads:

a) Ensure your bicycle is roadworthy.

b) Make yourself familiar with the traf󷴲c rules in your country.

c) Ride with caution. Do not endanger or provoke other road users.

d) Cycling is not allowed on motorways. Danger to life! Please check

the regulations in your country.

e) For safety reasons you are not allowed to listen to music through

headphones on public roads. Do not use your mobile either.

f) Keep suf󷴲cient distance between you and the vehicles ahead. Their

stopping distance is usually signi󷴲cantly shorter.

g) In wet conditions please cycle with caution. With less grip your stop-

ping distance will get longer. At about 18 kmh (11 mph) you make about 5 metres per second. In wet conditions the stopping distance is twice to three-times as long as in dry conditions. Adapt your riding habits to the ever changing conditions on the street. Be sure to cycle at moderate speed and do not brake too late.

h) Switch on the lighting in poor visibility conditions, such as fog, rain,

dawn, dusk and darkness. Bright clothing will help you to get noticed, especially in poor light. Be sure to wear straight cut trousers or straps or cycle clips when you set off on your bicycle. A helmet and protective glasses (b) are a must for cycling safely.

i) The following places are typical accident blackspots, where you

should cycle with particular caution:

• Junctions, even with a cycle lane parallel to the road; danger by cars

running in the same direction and turning to the left or right; danger by oncoming traf󷴲c.

• Crossing railway tracks can be hazardous for cyclists, as a trapped

front wheel can throw the cyclist off. Be sure to cross railway tracks at right angle.

• With a truck or bus besides you, e.g. in front of traf󷴲c lights. You may

be overlooked by the driver and are at risk of being run over when the truck or bus turns to the left or right.

• On cycle lanes: take care of loose dogs and children crossing the lane

unmindfully.

Make yourself familiar with the traf󹞬c rules before cycling on

public roads. Anticipate the mistakes of other road users!

Parents should take their time to introduce their children (a) to safe cycling on public roads. In Germany e.g. children must cycle on pavements until the age of eight. Between the age of eight and ten they are still allowed to do so. For crossing the street, children must get off their bicycle.

Parents are advised to sign their children up to courses where they learn how to safely cycle on public roads offered by road safety organizations or the like.

4.2 Environment - Cycling Off-Road.

A bicycle is the ideal means of transport for any nature lover (b). Today, cycling plays a major role in recreational activities. Cycling through parks and forest trails has become most popular. To protect nature and avoid

con󷴳icts between cyclists, hikers and municipal authorities it is crucial

that certain basic rules are followed.

To protect wildlife habitat and the 󷴳ora, please ride on signposted tracks and lanes only and avoid any off-road cycling across grassland, 󷴲elds

and through forest. Never ride through waters! Be sure when riding off road that you do not ride faster than your cycling skills allow.

Always be respectful to walkers and hikers and ready to brake when riding downhill or if the road ahead is not clear. Mind your speed and do not leave skid marks. Please throw your litter in litter bins or take it home.

Ensure an environmentally friendly disposal of lubricants, cleaning and care products after use. These agents must not be disposed of with domestic waste, in nature or emptied into drains.

Cycling off-road requires a great deal of skill, physical 󹞬tness and full concentration. Start with easy cycling tours and

increase the degree of dif󹞬culty step by step. Please note that

though looking easy, the tricks of a professional actually require years of training. Do not overestimate your riding skills!

5 BRAKE SYSTEM.

5.1 General Information.

Brakes (a+b) are used for adjusting one’s speed to the surrounding

terrain and traf 󷴲c. In an emergency situation, the brakes must bring the

bicycle to a halt as quickly as possible. In the process of such emergency braking, the rider’s weight shifts forward, thus reducing the load on the rear wheel (c). The rate of deceleration is primarily limited by the danger of the rear wheel losing contact with the ground resulting in an overturning of the bicycle and secondly by the tyres’ grip on the road. This problem becomes particularly acute when riding downhill. Therefore, in case of an emergency braking situation you have to try to put your weight back as far as possible.

Actuate both brakes simultaneously and bear in mind that, due to the weight transfer, the front brakes can generate a far better braking effect on a surface with good grip.

The braking conditions on unpaved surfaces differ, i.e. overbraking the front wheel can make the wheel slip away. Therefore, be sure to practise braking on different kinds of sur face.

Wet weather reduces the braking power. Apply the brakes carefully when riding on wet or slippery surface, as the tyres can easily slip away. Therefore, reduce your speed when riding in such conditions.

Prolonged braking or permanent dragging of brake pads can lead to overheating of the rims in the case of rim brakes. This can damage the inner tube or make the tyre slip on the rim causing a sudden loss of air which could lead to a serious accident.

With disc brakes too, prolonged braking or permanent dragging of brake pads can lead to an overheating of the brake system. This can lead to a reduction of the braking power or brake failure. Risk of accident!

When riding downhill, get used to braking hard and then releasing the brake again, whenever the road surface and the situation allows for it. If you are in doubt about the braking action, stop and let the brake system cool down.

The assignment of brake lever to brake calliper can vary (d), e.g. left lever acts on front brake. Make yourself familiar with the lever-to-brake assignment or ask at a bicycle specialist shop of your trust to change the brakes as you want them.

Be careful while getting used to the brakes (a). Practise emergency stops in a place free of traf󹞬c until you are comfortable controlling your bicycle. This can save you from having accidents.

Wet weather reduces your braking power and the road grip of the tyres. Be aware of longer stopping distances when riding in the rain, reduce your speed and actuate the brakes carefully.

Ensure that braking surfaces are absolutely free of wax, grease

and oil. Risk of accident!

5.1.1 Brakes – How They Work and What to Do about Wear.

Actuating the hand lever on the handlebars (b) causes a brake pad to be pressed against a brake surface, and the ensuing friction slows down the wheel. If water, dirt or oil gets in contact with one of the braking surfaces,

this changes the coef󷴲cient of friction and deceleration is reduced. This

is why brakes respond with a slight delay and less powerfully in wet weather.

In order to maintain their effectiveness, brakes need to be checked and readjusted regularly.

5.2 Rim Brakes.

The friction generated by braking causes wear to the brake pads (c) as well as to the rims. Frequent rides in the rain and dirt and over hilly terrain can accelerate wear on both braking surfaces.

Rims are provided with wear indicators, i.e. grooves (d) or circular indentations. If the rim is worn down to the point where the grooves or indentations are no longer visible, they need to be replaced. Once the abrasion of the rim has reached a certain critical point, the rim may break under the tyre pressure. This can make the wheel jam or the inner tube burst, both of which can cause an accident!

The grooves in the brake pads are worn down by braking. See a bicycle specialist shop of your trust and ask them to examine the remaining thickness of the rims when you have worn through your second set of brake pads at the latest. They have a special measuring device for determining the remaining thickness of the rims.

Wet weather reduces your braking power. Be aware of longer stopping distances when riding in the rain!

When replacing any parts be sure to only use parts that bear the appropriate mark and, to be on the safe side, original spare parts. Your BMW partner will be pleased to order the respective original spare parts for you!

Ensure that the brake pads are absolutely free of wax, grease

and oil.

Have your rims regularly inspected and measured at a bicycle specialist shop of your trust (a).

Brake cables that are damaged (b), e.g. frayed, should be replaced immediately, as they can otherwise fail in a critical moment, possibly causing an accident.

5.2.1 V-Brakes.

Common V-brake designs have two brake arms mounted separately on either side of the rim. When actuating the brake lever, both arms are tightened by the cable, the pads touch the rim.

5.2.1.1 Functional Check.

Check whether the brake pads are accurately aligned with the rims and

still suf󷴲ciently thick. You can judge the wear of the brake pads by the

appearance of the grooves. If the pads are worn down to the bottom of the grooves, it is time to replace them.

The brake pads must hit the rim simultaneously, 󷴲rst touching it with the front portion of their surface. At the moment of 󷴲rst contact the rear por-

tion of the pads should be a millimetre away from the rim. Viewed from the top the brake pads form a “V“ with the trough pointing to the front

(c). This V-shaped setting prevents the brakes from screeching when

applied.

The brake lever must always remain clear of the handlebars. You should not even be able to pull them all the way to the handlebars in the event of an emergency stop.

Only a successful passing of all these points will ensure a correctly adjusted brake.

Adjusting the position of the brake pads relative to the rims requires a considerable degree of skill. Replacing and adjusting the brake pads is a job best left to a bicycle specialist shop of your trust.

5.2.1.2 Power Modulator (d).

Some V-brakes are 󷴲tted with a power modulator that acts as brake

force control during braking hereby limiting the brake force.

This device is intended to prevent overbraking and a blocking of the front wheel.

An inappropriately adjusted power modulator may result in severe accidents. Ask at a bicycle specialist shop of your trust

about the system your bicycle is 󹞬tted with.

5.2.1.3 Synchronising and Readjusting.

Almost all brake designs have a bolt located next to one or both brake callipers for adjusting the initial spring tension (a). Adjust this bolt carefully until the distance between brake pads and rim is the same on either side.

To adjust the brakes, unscrew the knurled lock ring located at the point where the brake cable enters the brake lever on the handlebars (b).

Unscrew the knurled, slotted adjusting bolt by a few turns. This reduces

the free travel of the brake lever. Keeping the adjusting bolt 󷴲rm, tighten

the lock ring against the brake lever mount. This prevents the adjusting bolt from coming loose by itself.

Ensure that the slot of the bolt faces neither for ward nor upward, as this would permit water or dirt to enter.

Always test the brakes’ function while stationary after adjusting them, making sure the brake pads engage fully with the rim when you pull them hard.

5.3 Disc Brakes.

The most striking feature of disc brakes (c) is that they combine outstanding braking power with good weather resistance. They respond a lot faster in wet conditions than rim brakes do and achieve their normal high braking power within a very short time. They require fairly little maintenance and do not wear down the rims as rim brakes do. However, they tend to be noisy when they are wet.

New brake pads have to be bedded in before they reach their optimal braking performance. For this purpose, accelerate the bicycle 30 to 50 times to around 30 km/h (18 mph) and bring it

to a halt each time. This procedure is 󹞬nished, when the force

required at the lever for braking has stopped decreasing.

The brake levers can be adjusted to the size of your hands, allowing you to operate them with optimal ef fectiveness. In most cases this is done by means of a small Allen bolt located directly at the brake lever (d). You may need to readjust the brake pads, as well. Please read the manual of the brake manufacturer.

With mechanical disc brakes the travel of the brake lever becomes longer as the brake pads wear down ((a) p. 25). It is therefore necessary to readjust these brakes regularly. If you are in doubt or if you have any questions, please contact a bicycle specialist shop of your trust!

If your brake system works with DOT brake 󹞭uid, the latter

needs to be replaced regularly according to the intervals prescribed by the manufacturer.

The manufacturers of disc brakes usually deliver their products with detailed instructions. Be sure to read them carefully before removing a wheel or doing any maintenance work.

Disc brakes get hot in use. For this reason do not touch the brakes directly after stopping, especially after a long downhill ride.

Do not open the brake lines. Brake 󹞭uid can be very unhealthy

and damaging to the paint if it leaks out.

5.3.1 Checking Hydraulic Disc Brakes.

Regularly check the lines (b) and connections for leaks while pulling on

the lever. If brake 󷴳uid leaks out, contact your BMW partner immediately,

as a leak can render your brakes inef fective.

Check the pads for wear by inspecting the thickness of the braking material attached to the backing plate within the brake calliper (c) or view through the window on the upper side of the calliper (d). If there is approximately 1mm of material left on each brake pad, remove the pads according to the manufacturer’s instructions, check them thoroughly and replace them, if necessary.

Dirty brake pads and rotors can lead to drastically reduced braking power. Therefore, make sure the brake remains free of

oil and other 󹞭uids, especially when you clean your bicycle or

grease the chain. Dirty brake pads can under no circumstances be cleaned, they must be replaced! Rotors can be cleaned with warm water and mild soap. There are also special brake cleaners available.

Loose connections and leaky brake lines drastically impair

braking power. If you 󹞬nd leaks in the brake system or buckled

lines, contact your BMW partner immediately.

The manufacturers of hydraulic disc brakes usually deliver their products with detailed instructions. Be sure to read them carefully before removing a wheel or doing any maintenance work.

5.4 Roller, Drum and Back-Pedal Brakes.

These types of brakes are hardly found any more and only still common on touring bikes (a). The brake mechanism of these brakes is fully enclosed and combined with a geared hub. Their brake pads and surfaces

are largely protected against the in󷴳uences of the weather.

5.4.1 Checking and Readjusting Hand-Operated Brakes.

Check whether the inner cables of the Bowden cables in the area of the grips and brake itself are still in sound condition. They must not be frayed. Damaged cables should be replaced immediately, as they can snap. Brakes that have been adjusted at the brake lever only can lose their braking power.

Regularly check whether you get a positive braking response before the lever touches the handlebars (b).

To a certain extent, wear of the brake pads can be compensated directly at the hand lever. Unscrew the union nut on the bolt through which the cable enters the lever and then unscrew the bolt until the lever has the desired travel.

Retighten the lock nut by taking care that the slot of the bolt does not face upward or forward, as this would permit an unnecessarily high amount of water or dirt to enter (c).

Now check the functioning of the brake and see to it that the brake pads do not drag along the braking surface when you release the brake lever and let the wheel spin.

Repeated readjustment at the brake lever makes the arm on the brake calliper change its position. This can reduce braking power which may

be insuf 󷴲cient in an extreme case! After having repeatedly readjusted

your brake on your own, ask your BMW partner or at a bicycle specialist shop of your trust to do this delicate job.

If you intend to do any further adjustment on your brake, be sure to read the original instructions of the brake manufacturer before you start. In case you are in doubt, ask your BMW partner for help.

Check regularly whether the torque support is still 󷴲rmly attached to the

frame or fork (d). Use a torque wrench and never exceed the maximum

tightening torque! You will 󷴲nd the prescribed values in chapter “Recommended Tightening Torques”, directly on the components and/or

in the manuals of the component manufacturers.
