Safety

Proper use City and folding bikes serve to transport a single person on paved roads and paths in public road traffic. In this connection, the tyres must be in constant contact with the ground. They are for private use. The safety equipment required pursuant to the German Road Traffic Act (StVZO) must be present and is usually included. Any other use is not considered to be proper use. City and folding bikes are not suitable for the following:  jumps  riding on stairs  riding through deep water  participation in sports events Mountain bikes serve to transport a single person. Due to the fact that safety equipment is usually not necessary for mountain bikes according to the German Road Traffic Act (StVZO), they are intended for use away from public roads. Mountain bikes are not suitable for the following:  jumps  wheelies  stunts  downhill  riding on stairs  riding through deep water  participation in sports events Proper use also includes compliance with the recommended maintenance intervals as well as reading and understanding this manual.

9 Safety

Basic safety instructions

Prevent serious injuries or death from mechanical defects and handling the bike incorrectly Bike riding can lead to serious injuries or death from mechanical defects or incorrect handling of the bike.  Always perform a safety test before riding your bike (see the Riding the bike section starting on page 86).  Familiarise yourself with the brakes, pedals and changing gears before the trip.  Always ride at a speed that corresponds to the riding conditions.

Prevent electric shock or explosion from improper handling of the battery and charger Handling the battery and charger incorrectly can lead to an electric shock or explosion. A serious injury or death may be the consequence.  Only use the battery included with the delivery.  Never connect the positive terminal of the battery to the negative terminal.  Protect the battery from direct sunlight.  Do not disassemble and clean the battery.  Only use the charger included with the delivery for charging the battery.  Only use the charger indoors.  The connector of the charger is the cut-off device from the power grid. Make sure that the power outlet is close to the charger and is easily accessible.  Only use the charger with an earthed 230 V power outlet.  Keep the metal contacts clean, or clean them with a soft and dry cloth if necessary.  Do not charge a battery with visible damage, e.g. a broken housing.  Never put a battery with visible damage, e.g. a broken housing, into operation.

10 Safety

 Never let the battery fall.  Charge the battery in a temperature range between 10° and 30°.  Make sure that the charger is only used by persons without any limited physical, sensory or mental capabilities.

Prevent fire or explosion A short circuit can be caused by moisture, electrically conductive soiling or mechanical damage. The consequence may be the battery catching fire or exploding.  Clean the electric motor and control unit exclusively from the outside with a damp sponge. Never use a high-pressure cleaner.  If these components are accidently completely submerged in water, disconnect the motor from the battery immediately and do not put it back into operation again before having it checked by the manufacturer.

Prevent serious injuries from body parts coming into contact with components of the bike When riding, parts of the body or other objects can come into contact with the teeth of the sprockets, the moving chains, turning pedals and crank arms as well as the turning wheels of the bike. A serious injury may be the consequence.  When riding, make sure that parts of your body do not come into contact with the components of the bike mentioned above.

11 Safety

Prevent serious injuries from damaged components When riding off-road or over kerbs, the electric motor, crank arms or the bottom bracket can be hit and damaged. A serious injury may be the consequence.  Only use the bike on approved paths.  In the event of obstacles, dismount and lift up the bike.  In the event of damage, have the bike checked by a specialist dealer.

Prevent serious injuries or death during wet weather Wet weather adversely affects road holding, braking behaviour and vision, both for bike riders as well as other road users. The braking power of your brakes is reduced considerably in wet weather (as well as the brakes of all other road users). In addition, tyre treads do not grip anywhere as good as they do on dry roads. This hampers speed control and increases the risk of losing control over the bike. Serious injuries or death may be the consequence.  Always ride slowly in wet weather.  Always brake proactively and carefully in wet weather.  Switch off the electric motor or ride carefully with the lowest motor assist.

Prevent serious injuries or death at twilight or in the night Riding at night and at twilight is more dangerous than during the day. It is hard for other road users to see bike riders, and therefore this can result in serious injuries or death.  Avoid riding at night and at twilight.  Always ride slowly.  Always ride with bike lights and reflectors.

12 Safety

 Always avoid dark areas and areas with heavy or fast traffic.  Always avoid road obstacles.  If possible, ride on familiar routes.

Prevent serious injuries or death from damaged, bent or loose reflectors and lights The bike’s reflectors capture and reflect the light from streetlights and car headlights so that you are recognised as a cyclist. Damaged, bent or loose reflectors can result in you not been seen clearly by other road users. Serious injuries or death may be the consequence.  Check reflectors and their mounting regularly.  Have damaged, bent or loose reflectors replaced by your specialist dealer.

Prevent serious Injury when riding off-road or over kerb edges Riding off-road or over kerb edges without adjusting your speed can result in a fall. A serious injury or death may be the consequence.  Always ride at a speed that corresponds to the prevailing conditions.

13 Safety

Prevent serious injuries or death from replacement of components or adding accessories There are numerous components and accessories available that can improve the comfort, performance and appearance of the bike. These components or accessories are added at your own responsibility. It can be that these components or accessories have not been tested by the bike manufacturer for compatibility, reliability or safety. Unconfirmed compatibility, reliability or safety as well as improper installation, use and maintenance of components or accessories of the bike can lead to serious injuries or even death.  Always contact your specialist dealer before the installation, use and maintenance of the components.  Always read and follow the instructions for use included with the accessories.

Prevent serious injury from incorrect maintenance, care and cleaning Incorrect maintenance, care and cleaning can lead to injuries or even death.  Only perform the activities given in the maintenance plan.  Only use commercial lubricants and cleaning agents.  Have other maintenance work as well as repairs carried out by a qualified specialist dealer.

14 Safety

Prevent serious injuries or death from damaged components The bike and its components are subject to wear (scratches, cracks, fraying) and tear. A damaged component can suddenly and immediately malfunction, which can lead to injuries and even to death.  Check the components (e.g. brake pads, tyres, etc.) regularly for wear and tear.  Replace them (if possible) or have the damaged components of the bike repaired by a qualified specialist dealer.

Prevent breathing difficulties and choking When new, the materials that are used (e.g. paint) give off vapours as does the electric motor when the temperature is too high. The vapours can become concentrated when storing the bike in closed rooms. Breathing difficulties or choking can be the consequence.  Always store your bike in a well-ventilated room.

Prevent burns Components of the bike (e.g. brakes, wheels, etc.) can become hot when riding. Touching these components can cause burns.  Allow all hot components to cool down before any activities on them, or wear heat-resistant safety gloves.

Prevent injuries to your legs Injuries can occur to your legs from too small of a distance between pedals (Q Factor). There is a risk that the rider will have problems with the installed crank arm set.  In this case, have your bike modified by a specialist dealer.

15 Safety

Prevent vibrations The electric motor might not run smoothly as a result of incorrect assembly, wear and overloading (e.g. the electric motor hitting when riding over bumps, ridges) or from detached parts.  Only use the bike on approved paths.  Before each bike ride, check the drive unit to make sure it runs smoothly and without any play.  In the event of creaking, grinding noises or obvious damage, go to a specialist dealer and have the bike repaired. When using the bike on a road or also off-road, vibrations from the surface you are riding on will be passed on to your body.  Only use the bike on approved paths.

Prevent disorders Sitting on the saddle frequently and for long periods of time can result in disorders of the prostate for men.  Install (if necessary) a saddle that is ergonomically suitable for females/males.  Take precautions if applicable.

Prevent dehydration from cycling Cycling is a strenuous physical activity.  Always make sure you have a sufficient supply of liquids.

Prevent freezing Freezing can occur when cycling in cool and cold temperatures.  Always be sure to wear suitable clothing, including face protection, in the event of cool or cold temperatures.

16 Safety

Prevent falling from a suddenly occurring electric motor assist A suddenly occurring electric motor assist results in the risk of losing control and thereby falling.  Always test the electric motor assist before the first ride.  Always wear personal protective equipment (PPE).

Prevent poisoning Material or vapours can leak out of damaged components of the bike (e.g. batteries, electric or electronic components). Poisoning of the environment may be the consequence.  Dispose of used batteries and electric or electronic components of the bike according to legal requirements.  Observe the specifications of the manufacturer of these products in this connection.

Prevent property damage Improper handling of the battery can lead to property damage.  Make sure that the battery is not completely discharged (total discharge).  Only store the battery at a dry location with low air humidity.  Make sure that the stored battery is charged at least every six months.

Auxiliary drive Electric motor Depending on the type of bike, the existing electric motor acts directly on the rear wheel, or it assists you when pedalling. With the existing control unit, you can set the degree to which the electric motor is to assist you. There are different speed levels available for this. The electric motor assists you up to a maximum speed of 25 km/h. Battery A battery is required to operate the electric auxiliary drive. Depending on the type of bike, it can be attached at different positions, for example  under the carrier  on the down tube  on the saddle tube  in the frame. The battery can be removed from the support with the respective key for charging. Only use the battery charger included with the delivery for charging the battery. You can find more information on page 60. Depending on the type of battery, it can be equipped with the following connectors, displays or controls:  socket for charging  USB port  LED to visualise the charge level  Green: charge level ok  Red: charge level at 30%

28 Description

 Red flashing: charge level less than 10% (charge battery)  Button to check the charge level  On/off switch  Lock for removal  Bracket for pulling it out of the housing Like most large batteries, lithium-ion batteries are considered to be a hazardous substance according to shipping regulations. If the battery pack is installed on the bike, then transport by water and land are allowed. The regulations for hazardous substances apply for air transport. (Please check the local shipping regulations.)

Control unit There is a control unit to individually set the assistance by the auxiliary drive. The corresponding control element for this is normally mounted on the handlebars. You can find more information on operating the control unit on page 71. The control unit calculates the level of motor assist depending on the set speed level, speed and pedal force. The assist is active up to a maximum speed of 25 km/h. No assist is possible at higher speeds.

Suspension Some bikes are equipped with suspension. It helps to protect the rider and bike against bumps and vibrations that result from contact with the ground. The suspension can be attached to the front wheel, rear wheel or the seat post. There are three different suspension systems, which cannot all be addressed in this manual, for example elastomer springs, steel springs and air-oil shock absorbers. If your bike has a suspension system, read the use and service instructions and follow them. If you do not have the instructions for use from the manufacturer, contact your specialist dealer or the manufacturer.

29 Description

Brakes The brakes serve to control the speed and to slow down the bike until it comes to a stop. The following types of brakes are common:  disc brake  rim brake  backpedal brake.

Disc brake Brakes are mounted on the front and rear wheel. With disc brakes, a mechanism is used to press the brake pads (1) against one or both sides of a brake disc (2) to slow down the bike. The brake disc is fastened to the hub. The brake pads normally consist of rubber, sintered metal, semimetal or they are organic and subject to wear. You actuate the disc brakes by the brake levers mounted on the handlebars. Depending on the configuration, the disc brakes are actuated mechanically or hydraulically.

30 Description

Rim brake Brakes are mounted on the front and rear wheel. With rim brakes, a mechanism is used to press the brake pads against the rims from both sides to slow down the bike. The brake pads normally consist of rubber and are subject to wear. You actuate the rim brakes by the brake levers mounted on the handlebars. Depending on the configuration, the rim brakes are actuated mechanically or hydraulically.

Backpedal brake A backpedal brake is mounted on the hub of the rear wheel. The backpedal brake has low maintenance and low wear. You actuate the backpedal brake by turning the pedal backwards.

Gearshift You bike may be equipped with a derailleur system or an internal- gear hub. The following terms are used in the following: Downshift means shifting to a lower gear, which makes pedalling easier. Upshift means shifting to a higher gear, which makes pedalling more difficult.

Derailleur system A derailleur system has the following components:  a sprocket cassette in the rear wheel  a rear derailleur  a front derailleur  one, two or three chain rings  a drive chain  shifting levers

36 Description

The requirement for a perfect gear change with a derailleur system is for the drive chain to be moving forwards and be under at least some tension. You can select a suitable gear for the respective riding situation either with the front chainrings or rear sprockets. If, for example, you want to ride up an incline and only use a small amount of force when pedalling, then downshift. You have the following possibilities for this: Use the front derailleur to shift to a smaller chainring, or use the rear derailleur to shift to a bigger sprocket. If, for example, you want to increase your speed on level ground and apply more force for this, then upshift. You have the following possibilities for this: Use the front derailleur to shift to a bigger chainring or use the rear derailleur to shift to a smaller sprocket.

Incline Level

37 Description

Experiment with up- and downshifting to get a feeling for the different gear combinations. Initially practice shifting in situations without any obstacles or traffic until you can handle this with confidence. For information on using the shift levers, see page 66.

38 Description

Internal-gear hub An internal-gear hub can be equipped with 3, 5, 7 or 12 gears. The gear with the lowest number (1) is intended for the steepest inclines. The gear with the highest number (3, 5, 7 or 12, depending on the number of gears in your hub) is intended for the highest speeds. Shifting from an easier, “slower” gear (e.g. 1) to a more difficult, “faster” gear (e.g. 2 or 3) is referred to as upshifting. Shifting from a difficult, “faster” gear to an easier, “slower” gear is referred to as downshifting. Experiment with up- and downshifting to get a feeling for the different gears. Initially practice shifting in situations without any obstacles or traffic until you can handle this with confidence.

Pedals A pedal is mounted on the end of each of the pedal cranks. The pedals are pushed down alternately by the feet. This drives the bike chain via the chainring. The following types of pedals can be mounted:  block pedals  bear trap pedals  step-in pedals  pedals with hooks and straps  fold-up pedals (for folding bikes) Block pedals are equipped with non-slip rubber or plastic inserts on the support surfaces. Bear trap pedals consist of a metal cage that is equipped with spikes on the top and bottom. They ensure that the sole of the shoe has a firm hold on the pedals. Step-in pedals are mainly found on racing bikes and mountain bikes. Cycling shoes with special cleats under the soles are required for this. The foot with the shoe snaps into the mechanism of the pedal via this cleat. The foot is then connected to the pedal.

39 Description

This enables effective and uniform pedalling during the up and down movement. The connection can be broken immediately by twisting the foot to the side. Pedals with hooks and straps are hardly used at all since the arrival of step-in pedals. Here, the foot is connected to the pedal via hooks and secured by the straps. Folding bikes are equipped with fold-up pedals. They can be folded up to make it easier to transport the folding bike.

Check the size of the bicycle

WARNING Possible to fall off the bike due to a loss of control from an incorrect bike size. Serious injuries may be the consequence.  Make sure that the bike size matches your body size.  Do not ride a bike that does not match your body size.

Determine the distance between the top tube of your bike and your crotch when you stand with your feet slightly apart above the top tube of your bike. For a bike you ride only on paved surfaces and never off-road, this distance should be at least 5 centimetres. For a bike you ride on unpaved surfaces, this distance should be at least 7.5 centimetres. For a mountain bike with which you ride on difficult terrain, this distance should be at least 10 centimetres. Proceed as follows to determine the clearance:  Stand astride the top tube with your feet apart directly behind the saddle of your bike, and do this while wearing the shoes that you will also be wearing when cycling.

48 Before the first ride

 Shift your weight onto your heels. If your crotch touches the frame, the bike is too big for you.

If your new bike is not the right size, please contact your specialist dealer and exchange it before you ride it.

49 Before the first ride

Adjusting the Saddle The correct setting of the saddle is important for safe riding. You can make the following adjustments to the saddle:  height  distance from the handlebars  tilt of the saddle. To check whether the saddle height is set correctly, proceed as follows:  Sit on the saddle.  In the process, hold onto a railing, for example.  Move the pedal to the bottom position.  Place your heel on the pedal. The setting of the height is correct when your heel is on the pedal in the bottom position, and your leg is almost fully extended. If your leg is not completely extended, then the saddle has to be set higher. If you need to move your hips to reach the pedal, then the saddle has to be set lower. To set the saddle height, proceed as follows:  Loosen the saddle clamp with the appropriate tool.  If there is a quick-release fastener, open it. You can now move the saddle up and down and adjust the height.  Make the desired setting.

WARNING Falling from the bicycle possible from the seat post breaking Serious injuries may be the consequence.  Make sure that the marking on the seat post showing the minimum insertion depth is in the seat tube and not visible.

50 Before the first ride

 Tighten the saddle clamp again.  If there is a quick-release fastener, close it.  Check whether the seat height is set correctly now.  If not, repeat the adjustment process. When you are sitting on the saddle of the bike, you need to be able to operate the brake levers and gear levers properly while riding. In the process, angle your elbows slightly. To adjust the distance and the tilt of the saddle to the handlebars, proceed as follows:  Loosen the nut or screw under the saddle with a suitable tool until you can move the saddle.  Do not remove the nut or screw.  Slide the seat to the desired position.  Tighten the nut or screw under the saddle with the corresponding tool.  Check whether the distance to the handlebars is set correctly now.  If not, repeat the adjustment process. Most cyclists prefer to have the saddle with a horizontal alignment. The alignment of the saddle can be checked with a spirit level. If you prefer a different alignment, you can adjust the tilt of the saddle.

Adjusting the handlebars The adjustment of the handlebars depends on the type of stem. The stem connects the handlebars with the fork. There are essentially three different types of stems:  ahead stem  conical stem  stem with variable angle.

51 Before the first ride

Ahead stem With this type of stem, you can adjust the alignment of the stem and the angle of the handlebars. The height of the handlebars cannot be set. If you need to change the height, ask your specialist dealer.

ATTENTION! Possible for fork to fall out and cause parts to be lost.  Make sure that the front wheel or alternatively the fork is on the ground before loosening the screw on the cap.

To set the alignment of the handlebars proceed as follows:  Make sure that the front wheel or alternatively the fork is on the ground.  Loosen the screw of the cap (1) minimally.  Loosen the screws (2) that secure the stem by about one revolution. Now you can align the stem including handlebars.  Turn the stem including the handlebars to the desired position.  Tighten the screw of the cover with max. 3-5 Nm.  Tighten the screws (2) to secure the stem.

52 Before the first ride

The handlebars are secured to the stem plate with a clamping device. To set the angle of the handlebars, proceed as follows:  Loosen the existing screws (1) until you can turn the handlebars in the clamping device.  Turn the handlebars to the desired position.  Make sure that the handlebars are centred.  Tighten the screws crosswise until the handlebars are securely fastened.

Actuating the brakes Brakes are there to control the speed and not just to stop the bike. The maximum braking force of the wheels is available shortly before "blocking" (standstill) of the wheels and the subsequent skidding. As soon as the tyre skids, you lose much of the braking power as well as any control of the bike. You must practice braking and stopping gently and without blocking the wheels. This technique is called progressive brake modulation.  Squeeze the brake lever towards the handlebars and gradually increase the braking force. If you feel that the wheel is blocking, reduce the braking force so that the wheel can just continue to turn and not block.

Actuating the gearshift Your bike can be equipped with different gear selectors:  classic shift lever  modern shift lever  rotary gearshift.

66 Operating the bike

Use the shift levers or the rotary gearshift on the right side of the handlebars to operate the rear derailleur. Use the shift levers or the rotary gearshift on the left side of the handlebars to operate the front derailleur (if available). Depending on the type of bike, your bike may be equipped with a shift indicator near the gear selector. This allows you to see at a glance in which gear you are riding. The higher the displayed number, the smaller the sprocket that is currently being used, or alternatively the bigger the chainring. To operate the rear or front derailleur with a classic or modern shift lever, proceed as follows:  Turn the pedals forward.  Press the lower lever (2) forward with your thumb to switch to a larger sprocket or alternatively chainring.  Pull the upper lever (1) with your index finger to switch to a smaller sprocket or alternatively a smaller chainring.

85 Riding the bike Riding the bike

Always wear a cycling helmet when riding, which meets the latest certification standards. Follow the manufacturer’s information from the related manual in connection with the adjustment, use and care of the helmet. The majority of serious injuries caused by cycling are head injuries, which could have been prevented with a helmet. To be able to participate in public road traffic safely with your bike, it requires the following equipment according to the German Road Traffic Act:  a bell  two independent brakes  a white front headlight  a white front reflector  a red taillight  a red rear reflector  yellow reflectors at the front and back of the pedals  two yellow reflectors in the spokes of each wheel offset from each other by 180°, or alternatively reflective white stripes on the tyre. Headlights and taillights powered by a rechargeable battery or battery are only permitted in Germany if they have Road Traffic Act approval.  Ensure the following points before each ride:  the battery is charged  the brakes, chain guard, fenders function properly  the handlebars are securely fastened and correctly adjusted  the saddle is securely fastened and correctly adjusted  the pedals are securely fastened  the wheels are securely fastened  the tyres are in perfect condition  the tyre pressure is correct

86 Riding the bike

 the lights works and are set correctly  the gearshift works and is set correctly  screws, nuts and quick-release levers are tight

Tips for safe riding  Observe all regional traffic laws and bicycle regulations. Observe the regulations regarding the licensing of bicycles and riding on the pavement, laws on the use of bike paths and so on. Observe the regulations regarding helmets and child seats and special traffic rules for cyclists. It is your responsibility to familiarise yourself with the laws and regulations and comply with them.  You are using the road or bike path together with motorised road users, pedestrians and other cyclists. Respect their rights.  Always turn on the lights.  Ride proactively. Always assume from that others are not able to see you.  Look forward and be prepared for the following:  vehicles that are braking or turning onto your road in front of you, as well as vehicles coming from behind  parked vehicles opening their doors  pedestrians on the road  children or pets playing near the road  potholes, storm drains, railroad tracks, expansion joints, road or pavement construction, debris or other obstacles that could possibly cause you to swerve into the opposite lane or catch your wheel or make you lose control and cause an accident.  Ride in the designated bike lanes and bike paths or as close to the edge of the road as possible in the direction of the traffic flow or as designated by local laws.  Stop at stop signs and traffic lights. Brake at crossroads and look in both directions. Do not forget that cyclists are always the weaker road users.

87 Riding the bike

Cyclists always draw the short straw when it comes to traffic collisions with cars.  Use common hand signals when turning or stopping.  Never ride with headphones. They drown out traffic noise and sirens, distract you from the traffic and can be caught in the moving parts of the bike, causing you to lose control.  Never let other people ride with you. Exceptions are toddlers who are wearing an approved helmet, and have to be transported in a properly fitted child seat or child trailer. Observe the weight restrictions given in the manufacturer's recommendations for the child seat or child trailer.  Never carry anything that obstructs your view, impairs your full control of the bicycle, or could become entangled with the moving parts of the bike.  Never allow another vehicle to pull you.  Do not perform any stunts, wheelies or jumps. They can result in injury or damage your bike.  Never weave your way through traffic, and don’t make any movements that might surprise the other road users.  Ride defensively and grant the right of way.  Never ride your bike while under the influence of alcohol or drugs.  If possible, avoid riding in bad weather, when visibility is poor, at dusk, at night or when you are very tired. All this increases the risk of accidents.

Tips for safe off-road riding  The different terrain conditions for cycling off the road call for high concentration and good riding skills. Begin slowly on easier terrain and improve your riding skills. If your bike is equipped with suspension, then the risk of losing control and falling increases with increasing speed. Familiarise yourself with how your bike handles before you increase your speed or ride on difficult terrain.

88 Riding the bike

 Wear proper safety equipment for your planned riding style.  Do not ride alone on terrain that is off the beaten track. Even if you travel together with others, you need to tell someone where you are and when you will return.  Do not perform any stunts, wheelies or jumps. They can result in injury or damage your bike.  Get to know the regional regulations regarding navigable terrain and riding off-road, and respect private property.  You will be using the area together with hikers, riders or other cyclists. Respect their rights.  Give pedestrians and animals the right of way. Ride so that they are not disturbed or endangered, and stay far enough away that their sudden movements do not endanger you.  Stay on the designated trail. Do not contribute to erosion by riding in mud or by unnecessary skidding. Do not disturb the ecosystem by making your own path or a shortcut through the vegetation or streams. It is your responsibility to impact the environment as little as possible. Leave everything as you found it, and take everything you bring back home with you.  Be well equipped. If something happens while you are riding off-road, it can take a long time until help arrives.

Riding with the auxiliary drive If you have been riding bikes without an auxiliary drive until now, you should first of all get used to the feeling of riding with an auxiliary drive in a traffic-free area. The auxiliary drive is only active when it is switched on and you are pedalling. The feeling when the auxiliary drive engages is initially unusual; however, you will soon get used to this assistance. Sit on the saddle before you start to pedal. Start with the lowest drive assistance, and practice everyday driving situations such as, for example:

89 Riding the bike

 getting started  accelerating  braking  cornering. If you stop pedalling, it may happen that the auxiliary drive continues to assist for a brief period of time. Therefore, stop pedalling sooner when approaching a curve before you turn or at a red light than you would with a bike without an auxiliary drive. Before stopping, shift into a gear early, which will enable you to start up again smoothly. The achievable range with the assistance of the auxiliary drive depends on the following:  total weight of the bike including rider and luggage  selected speed level  tyre pressure  battery charge level  route profile  weather  tailwind/headwind  amount of own power used. To achieve the greatest possible range, proceed as follows:  Make sure that the battery is fully charged.  Make sure that the tyre pressure is set correctly.  When riding on flat or sloped stretches, don’t use the auxiliary drive, or select only slight assistance.  Select the gear that is best suited to the riding situation.  Ride proactively to avoid unnecessary stopping and the subsequent starting process.

Riding without the auxiliary drive You can also use your bike without the auxiliary drive. To do this, you only have to switch off the auxiliary drive. Then, you can use your bike like a bike without an auxiliary drive, for example if the battery has been run empty.

Battery maintenance The battery is designed for about 500 charging cycles. After 500 cycles, the battery no longer has 100% capacity. The capacity is still about 60% after 500 cycles. A charging cycle involves charging the battery from 0% to 100%. Charging the battery from 99% to 100% does not count as a full charging cycle, but it counts only as 1% of a full charging cycle. 500 charging cycles usually last more than two years. You can store the battery with a charge level of 75% for around 5 months without recharging it. This is about three months for a charge level of 50%. In order to not shorten the service life of your battery, proceed as follows:  Charge the battery when the battery level is between 30% and 50% after riding.  Make sure that the battery is not completely discharged (total discharge). This can happen if the battery is discharged completely and then the bike is parked for several days.

The charging process of a totally discharged Zündapp battery (from 1% to 100%) takes:  7.2 Ah, 5 hours  8.8 Ah, 6 hours  10.4 Ah, 7.5 hours  14.5 Ah, 14.5 hours To store the battery for more than two months, proceed as follows:  Remove the battery.  Make sure that the battery has no visible damage, such as a broken housing, for example.  Charge the battery completely before long-term storage.
