• Do not move the saddle beyond the minimum insert line as this will damage the bike or cause potenIal injury
2. Saddle angle
• Using the #13 spanner, loosen the side bolt underneath the saddle by turning it anIclockwise.
• Tilt the saddle to the desired angle. Set this iniIally so the saddle is horizontal. Once you have ridden a few kilometres you may wish to adjust the nose for improved comfort.
• Tighten the side bolt to 20-­‐30Nm.
1. FiHng the pedals
• Look closely at the pedals to idenIfy the right andleg pedals.
• Using a #15 spanner, fit the right pedal by screwing it clockwise to 30Nm into the right crank.
• From the leg side of the bicycle, fit the leg pedalby screwing it anI-­‐clockwise to 30Nm into the leg crank.
• Pedals are assigned to leg and right, they are not interchangeable.
1. Chainrings
Chainrings are wear parts. Their service life depends on various factors, like maintenance and care, type of use and distance travelled.
2. Cranks
• Cranks must be securely fastened as this could otherwise damage the crankset.
• Cranks can come loose which is why you should regularly check whether they are securely fastened by aBempIng to rock them to and from the frame.
• If there is play in the cranks, have the bike checked and the cranks fastened securely by a professional bike workshop.
1. Check the brakes:
• Pull the front wheel and then the rear wheel handbrake lever with the same amount of force as you would apply when braking sharply during a ride.Then push the bike forwards.
• The rear wheel should lock and the front wheel should decelerate so rapidly that the bike starts to Ip forwards.
• The gap between the brake block and the rim should be roughly 1 mm.
• If required, you can readjust the rebound force via the spring adjustment screw so that both brake arms move symmetrically.
• Once you have done this, check that the brake is working properly.
2. AdjusIng the brake withbrake cable adjusIng bolt
• If the brake is not working properly or the travel distance of the brake lever is too great, you can adjust the brake using the cable adjusIng bolt on the brake lever
• Turn the cable adjustment bolt to adjust the clearance between the brake pad and the rim. • Turn the bolt inwards (clockwise) to increase the brake-­‐pad clearance. • Turn the bolt outwards (anIclockwise) to reduce the brake-­‐pad clearance. • The clearance between the brake blocks and rim should be roughly 1 mm.
3. Wear of brake pads
• Most brake pads for rim brakes come with grooves or notches. If these grooves are worn and can no longer be seen, this is normally a sign that the brake pad is worn.
Do not ride your bike if the brake pads are worn. Have them replaced by a professional bike workshop instead.
Check the brake blocks regularly for signs of wear.
If notches or grooves are no longer visible, it is normally a sign that the brake pad is worn and needs to be replaced (image below).
Have them replaced by a professional bike workshop.
Worn: Ok:
1. LubricaIng the chain
• Clean and lubricate your bike chain regularly, especially if the bike has been ridden in rain.
• For lubricaIng the chain, only use products recommended for bicycle chains.
2. Check the wear of the bike chain
• Take the secIon of the chain that rests on the front chainring between your thumb and forefinger
• Pull the bike chain off the chainring. If the bike chain can be liged by a significant amount, it is worn and must be replaced by a new one.
• With hub gears, the chain tension must be adjusted so that verIcal play of one to two cenImetres is present in the unsupported chain span between the chainring and sprocket wheel.
• The chain should be replaced by a professional bike workshop ager roughly 3000km.
3. AdjusIng the chain tension
• Loosen rear wheel nuts with the #15 spanner.
• Pull the wheel back into the dropouts unIl the right amount of play is in the chain.
• Tighten the rear wheel nuts to 30-­‐40Nm. Tighten the chain tug nut if necessary.
1. OperaIng hubgears
• Turn the twist-­‐shig lever to select all 7 gears.
• For Increasing pedal force, move the indicator towards 7
• For Decreasing pedal force, move the indicator towards 1
2. AdjusIng gears

Take the inner tube out of the tyre.
3. Spare tyres and tubes
• Replace tyres and tubes with size 47-­‐622
4. FiHng the tyre and inner tube
• Make sure that the rim tape covers the spoke nipples and is undamaged.
• Put the rim with one edge inside the tyre.
• Push one side of the tyre completely into the rim.
• Insert the valve through the valve hole in the rimand fit the inner tube inside the tyre.
• Push the tyre over the rim sidewall.
• Pull the tyre forcefully into the centre of the rim.
• The area that has already been fiBed will slip into the base of the rim.
• Check once again that the inner tube is seated correctly.
• Push the other side of the tyre completely over the rim flange using the heel of your hand.
• Inflate the inner tube slightly.
• Check that the tyre is correctly seated and is true using the indicator ring on the rim sidewall.
• Adjust the seaIng of the tyre by hand if it does not run straight.
• Inflate the inner tube up to the recommended tyre pressure.
5. Pumping the tyre • Unscrew the valve cap to inflate the tyre.
• Inflate to the recommended tyre pressure (45-­‐65PSI).
• The opImum and maximum pressure values are also embossed on the sidewall of the tyre.
• Never exceed the maximum value!
• When inflaIng tyres out and about, if you press your thumbs hard into the inflated tyres, there should not be much give.
6. Front wheel reinstallaIon
• Replace the washers in the correct order.
• Place wheel on dropout ensuring that the cable is on the right-­‐hand side and is facing away from the fork, not to the fork!
• Tighten the wheel nut to 30-­‐40Nm with a #18 spanner.
• Reconnect the front brake cable and check that the brake is working.

• Remove the rear wheel from the rear dropout.
• If you need to disconnect the shiging cable as well, follow the steps in the separate hubgear system manual found inside your bike carton.
2. Installing the rear wheel
• Place the rear wheel on the dropout ensuring that the sprocket is on the right hand side.
• Replace the chain onto the rear sprocket.
• Fit the fixing washers onto both sides of the hub axle.
• Turn the shiging arm unIl the projecIons on the fixing washers engage with the slits in the dropouts. In this case the shiging arm can be mounted more or less parallel to the chain stay.
• The projecIng part must be on the dropout side.
• Fit the fixing washers so the projecIons precisely engage in the slits in the dropouts on the front or rear of the hub axle.
• Ensure the wheel is centred and the chain is the correct tension. • The shiging arm should be almost parallel to the chainstay.
• Tighten the wheel nut to 30-­‐40Nm with a #15 spanner.
• Close the quick-­‐release brake mechanism and check that the brake is working.
• Set the Revo-­‐shig lever from posiIon 4to posiIon 1 then back to posiIon 4. Check that the yellow marking lines sIll line up.
• Please also read the separate hub gear manual found inside the bike carton.
1. Checking the rims and spokes
• Check spokes are Ight, check rims for wear and distorIon.
• V-­‐ Brakes can cause wheel rims to become worn.
• If you noIce cracks or form changes in the rims, have them checked or replaced by a professional bike workshop. • Check the condiIon of the wheel rims regularly (check carefully every 500km)
1. Using the rear pannier
• When loaded with luggage, the pannier rack may affect steering and braking.
• If fiHng a child seat or a large item of luggage, read all manufacturer instrucIons carefully to ensure safety and prevent damage to goods or the bicycle.
• Ensure no straps can become caught in the wheels.
• When loading, ensure luggage is evenly distributed on the pannier rack.
• Ensure all pannier fastenings are secure – check them regularly.
• The pannier rack is designed for luggage only.
• The maximum permiBed weight of the bike is 120kg. This compromises the weight of the bike, the rider as well as any addiIonal luggage or a trailer.
• Do not carry more than 25kg of weight on the pannier rack.
1. The electric motor smoothly kicks in as you start to pedal with a barely audible sound. Being integrated into the front wheel hub, the motor is hardly visible, in keeping with the EMU bike’s sleek and chic design.
2. The power assistance provided by the motor enables you to cycle longer distances and with minimum effort to enjoy a comfortable, sweat-­‐free ride, yet sIll arriving at your desInaIon faster than a normal bike. If you add your own pedalling power you can gain a physical work-­‐out and take even more Ime off your journey.
3. The power-­‐assist funcIon kicks in once you start pedalling and stops shortly ager you stop pedalling and immediately upon braking. The motor will switch off when the bike is staIonary for more than 3 minutes. 4. In accordance with EU regulaIons, the motor is restricted to giving a maximum output of 250 waBs. The maximum speed permiBed is 25km/hr.
5. The motor is maintenance-­‐free and any work should only be carried out by a recommended specialist cycle workshop. Contact us at www.emubikes.com for advice and informaIon. Any work done on the motor or electrical parts by a non-­‐
recommended cycle shop will void the warranty.

USB charging port
Underneath the Display you will find a USB charging port to charge your smartphone or navigaIon devices
The Samsung lithium baBery is a high performance baBery which combines a long-­‐lasIng capacity of 10.4AH with a lightweight body. The baBery is designed to last for up to 700 full charges, if charged from 50% to full the baBery could last up to 3000 charges. In Ime, the baBery will age and wear out. (Even with no use a baBery life reduces with Ime). If you need a new baBery, we can supply one, details can be found online at www.emubikes.com.
1. To charge the baBery, connect it to the charger. Plug the charger into a wall socket.
2. It is important to charge the baBery fully before using it for the first Ime.
3. When the light on the charger turns green the baBery is fully charged.
4. Unplug the charger from the socket.
FiHng The BaBery
1. Place the boBom of the baBery into the holder.
2. Push the top of the baBery home and lock into place using the key.
3. Remove the key and keep safe.
4. The EMU electric bike is designed so that the baBery fits perfectly into the frame.
5. To remove the baBery, unlock and push it gently down towards the pedals and lig out.
6. Re-­‐charge the baBery fully each Ime you use the Emu bike.
7. To check the exisIng level of baBery charge, look at the Display Panel where the baBery level is indicated. Please see Display Panel secIon for details. BaBery Care
Fully charge the baBery before its first use
Re-­‐charge the baBery ager each bike ride, even short trips.
If you are not using the baBery, place in storage not below 10⁰C at approximately 50% of its charging capacity. Charge it every 2 months for 1 hour.
During colder months, the baBery may lose up to 25% of its capacity. It also takes longer to charge it at low temperatures, so it is best to store and charge the baBery indoors at room temperature between 10-­‐30⁰C.
Only charge the baBery using the charger provided. Any misuse can be dangerous and will void the warranty.
Do not use the charger for other electrical items.
Do not cover the charger as this may cause it to overheat and catch fire.
Always pull out the plug before cleaning the charger. Do not use water near the charger as this could damage and short-­‐circuit it.
If you have a problem with the baBery, always consult a recommended
specialist cycle workshop or contact us via our website www.emubikes.com.
The Emu bike is fiBed with high quality Spaninga front and rear lights with integrated reflectors.

TroubleshooJng Check List
Problem: No Power and display is OFF
1. Check the baBery is properly seated and locked in place.
2. Check that the baBery is charged by pressing the buBon on the baBery. 3. Check the connecIons and make sure the baBery power line is connected to the switch and the gauge is connected to the display panel. If the power works then it is a connecIon problem with the gauge. 4. If all is fine please charge the baBery for 4 hours and try again. If sIll no power, contact us at www.emubikes.com.
Problem: No Power and display is ON
1. Ensure the electronic brakes are returning to the normal brake ‘off’ posiIon, if not they will be disengaging the power.
2. If the problem persists ager you check the above then disconnect the electronic brakes at the display panel. If the power returns then you may have a faulty brake sensor.
Problem: IntermiBent power
1. If a power failure occurs ager stops it is almost certainly the brake levers. Have them serviced to ensure they return to the full off posiIon. Servicing normally involves the proper set-­‐up of the brakes and applicaIon of water expelling/lubricant soluIon to the brake cables. 2. If the moving crank sensor disc has become dirty or damaged you may experience an intermiBent loss of power while pedalling. Check the magneIc disc sensor for damage and dirt. It is located on the boBom bracket axle and is likely to require periodic cleaning.
3. If loss of power is experienced ager bumps it is most likely to be caused by a loss of connecIon.
4. Check the baBery contacts and ensure they are clean and making good contact. Checked?
5. Completely discharge and recharge the baBery twice. This is the least likely scenario but it is a required fault check.
6. When the power cuts out, test the voltage across the baBery terminals using a mulImeter and call us with this informaIon.
Problem: BaBery not charging
1. Check if the charger is working… If no light, check the plug fuse on the charger.
2. Are you connecIng the charger in the right order (see charging the baBery).
3. If you have a mulImeter check the voltage across the baBery terminals. If it is below 20-­‐Volts the charger may not be able to start charging and the baBery may be damaged.
Problem: Lower than expected range of baBery power
1. Ranges can vary dramaIcally from customer to customer under different riding condiIons.
2. Your bike may have an adjustable power/range seHng on the controller, this may need to be changed if you require a longer range.
3. Hills and loads over 90Kgs reduces the range significantly.
4. Please check the brakes are correctly set-­‐up i.e. not rubbing and the tyres are correctly inflated to 45 to 65 psi – this is the number one cause of reduced range.
5. If it is a new baBery it may take a few cycles (charge/discharge) before it fully opens up the capacity.
Problem: Motor noise
1. Be exact about when the noise is experienced: when running motor off load or under load, when cycling with motor switched off, when using pedals, before or ager braking etc. Ogen a service will recIfy noises.
2. Motors with durable metal gearing will make more noise and outlast motors that use plasIc cogs.
3. If the noise of your motor suddenly gets louder it is a good idea to have it checked out. Contact us.
You will find a troubleshooIng guide on our website www.emubikes.com where you will also find an email helpline and telephone number to call should you have any queries.

The product is CE-­‐marked 2013.
1. Always remove the baBery before cleaning your EMU bike.
2. Use a damp cloth or brush to clean the bike. Suitable cleaning materials are supplied by specialist cycle suppliers.
3. Do not use a hose or high pressure cleaner as this could damage the bike.
4. Make sure water does not enter the baBery and that you do not touch the electrical contacts either in the frame, or on the baBery.
An annual service is required to keep the warranty valid. Contact us at www.emubikes.com for details of recommended specialist cycle shops. Maintenance and repairs must only be done by a specialist cycle shop, recommended by us at EMU bikes.
Always ride wearing a helmet.
Be visible to other users of the road. Wear a reflecIve jacket at all Imes. See the Accessories secIon on our website or in this Manual.
Always switch on front and rear lights when the light condiIons are poor and as dusk falls.
Your EMU electric bike can be considerably faster than a non-­‐electric bike. Stopping distances will therefore be marginally longer. Take the Ime to get to know your electric bike before riding near traffic, or pedestrians.
Adjust your speed and expectaIons according to the road condiIons. In icy, or wet, weather the roads become more slippery and you will need to allow greater braking distances.
Avoid potholes, loose terrain, spills, and obstacles.
Do not carry adult passengers, or overload the bike.
You do not legally need a driving licence to ride an electric bike, but you should know the Highway Code relaIng to Rules for Cyclists – on www.gov.uk website.
Be aware that live parts connected to the electric motor may be live if covers or wires are exposed. Do not allow children to play with the Emu electric bike.
Eye protecIon
Good vision is vital for cycling safely. Many cyclists find it more comfortable to wear visors, or glasses to avoid such hazards as insects, dust or cycling in the rain.
Learn how to stop your bike safely. Apply both front and rear brakes at the same Ime with a steady pull on the levers. A good habit in traffic is to keep two of your fingers placed over the brake levers as you cycle so that you can brake quickly if necessary. PracIse breaking in dry and wet condiIons so that you feel in control at all Imes. Wet condiIons greatly increase the stopping distances needed and make roads slippery. Be aware of how your bike reacts in different condiIons and adjust your speed accordingly.
Cycling with the power assistance turned on enables you to go faster with less effort. You should be aware that the increase in speed means you need to allow for a greater stopping distance.
Always pedal with the ball of your foot, not the instep. To pedal efficiently ensure your foot is IlIng slightly downwards as you reach the boBom of the pedalling stroke and then slightly upwards at the top of the stroke.
Using the gears
The EMU bike has 7 hub gears. The lowest gear, 1, is used to start off or to climb hills. As you increase your speed change into gear 2 etc. moving up into top gear.
The gears enable you to keep a relaIvely steady pace as you pedal. In traffic it is best to change gears frequently as you slow down, stop at lights etc. and accelerate. Hub gears enable you to change down to a low gear whilst staIonary, doing so will make it easier to move off again. The power assistance kicks in ager a few pedal strokes.
Finally, always remember be alert and anIcipate so that you can react in good Ime to other road users, road condiIons and potenIal hazards like potholes etc. PosiIon yourself well on the road so that you are visible and have good visibility yourself. Be seen!
A full range of cycling accessories is available at www.emubikes.com
Enjoy your EMU bike and ride safely!
