When the E-bike is parked for approx. 10 minutes, the E-bike system switches off automatically.
Please visit our website: www.dwmeigi.us to check the manual of this LCD display, it has many functions and settings to meet the rider’s requirements.
Check before riding it for the first time:
The bicycle was assembled and checked before leaving the factory, nevertheless, before using for the first time, check the unit thoroughly.
- First, check to see whether the battery is fully charged and locked.
- Check the air pressure of the tires is normal
- Check and make sure the front and rear brakes are working properly
- Check the tightness of the front and rear wheels
- Check and make sure the handlebar and saddle are fastened tightly enough. Make sure the quick releases are locked and all lock nuts and screws are tightened.
Turn on the power switch (turn the ignition key to" ON” position), the power display indicator will light on, indicating the unit is powered.
Just like riding a normal bicycle, seat yourself on the saddle. Put one foot on the pedal and do a final check to see that everything is okay and working well, especially the breaks. Start pedaling, and when you reach a certain speed, the motor will automatically be activated and start to move your bike. To stop the bicycle motor, just stop pedaling and the motor will stop automatically. To bring the vehicle to a halt, use the brake. automatically and the motor will not work.
Battery level gauge:
When the battery is getting low, you will see it on the LCD display, as the battery indicator empties. When this occurs, turn OFF the power switch and only use the pedals to ride, without the assistance of the motor. You will have to charge the battery when you get to an electrical outlet and will be able to use the electric motor again once the unit is fully charged.
Shut the power “OFF” and pull out the key of the battery case while parking. The power switch should be turned “OFF” when pushing so that you don’t start up the motor by accident. Use a chain lock to further secure your bicycle when necessary.
Note: Don’t expose the e-bike to sunlight or rain for a long time, or some electrical components may behave abnormally.
Note: If you use the brakes frequently, turn the bicycle ignition on and off often, ride against the wind, ride uphills or are pedaling with a higher load on the bike, the battery will not last as long and you will not be able to travel as far using the battery.
Some model are equipped with gears. Gears are used to change the ratio between rotations of the rear wheel and the crank set. This enables you to pedal less and travel faster on flat or downhill sections, or pedal faster and travel
slower to climb hills. Gearing is independent to pedal assistance, so pedal assistance operates the same regardless of selected gear. Remember, however, that pedal assistance is "governed" by overall speed.
The freewheel (A) are located on the rear axle, known as a "gear cluster" or "cassette". The larger the gear, the less number of rotations per rotation of the crank. The largest gear is the "lowest" and is referred to as "1". As each
gear becomes smaller, it is a "higher" gear then the previous and is numbered sequentially. The number of gears may vary between different models. Beneath the gear cluster is the derailleur mechanism (B), which moves the chain so it
runs on different gears. The derailleur is operated by the rider using controls mounted on the handlebars. The gear change is "indexed" so each gear selection positively engages. There may be slight variations between bicycle
models in method to change gear "up" (from a lower gear to a higher gear), or to change gear "down" (from a higher gear to a lower gear). The image shows a "7-speed" type that uses a button (C) for changing up gears (push button to
activate derailleur), and a lever (D) for changing down gears (rotate lever forward to activate derailleur).
All bicycle models are equipped with a front and rear wheel braking system. Brakes are used to slow the bicycle down. The braking systems may use different mechanics, however, the functionality is the same, and that is to change the energy of the moving bicycle into heat energy ("friction"):
- For disc brakes, this means pads made from a special friction material pinching against a disc mounted to the centre of the bicycle wheel.
- The brakes are operated by the rider through levers mounted to the handlebars. The left-hand lever
operates the rear brake, the right- hand lever operates the front brake. The ability of the rider to
adequately slow and/or stop the bicycle depends largely on the skill of the rider, the surface being ridden
on and other factors such as rain, tyres, adjustment and condition of the brake parts etc
Guidelines for Using Brakes
To get the best performance and service life from the brake system, understand and apply the following techniques:
- In wet conditions, which reduces friction, always provide additional distance for braking and adjust how quickly you apply the brakes.
- When applying the brakes, particularly the front brake, use a lower pressure to start with until you feel the brakes starting to "bite", then increase pressure as required. Do NOT over-apply the brakes and cause the wheel to stop rotating – this may result in loss of control.
- Maintain the brake friction components (pads, shoes, rubbers) in good condition and replace when they reach the wear limit.
- Maintain brake adjustment so that the brakes perform effectively, the levers are comfortably positioned, and there is not excessive play in adjustable components.
- If the brakes are not performing effectively, making abnormal noise or any part is not serviceable or cannot be adjusted correctly, have the brakes inspected and adjusted by a bicycle mechanic or suitably qualified person.
- If the brake cables become frayed or otherwise damaged, have them replaced by a bicycle mechanic or suitable qualified person.
Batteries and Battery Charging
Before charging, you must turn the power switch to “OFF” and pull out the key. Keep the charger in a dry and ventilated condition when it’s working.
- Firstly, connect the output plug of the charger with the socket of the battery case properly, and then insert the input plug into the electrical outlet. The chargers indicator light will turn on, which means it’s charging.
- When the light turns from Red to Green, it means the battery has been fully charged. Usually, it will take about 4-6 hours to recharge the battery depending on the batteries state of charge. However, it’s a good idea to let it charge for an additional 2 hours after the light has turned green if it’s convenient for you, as it will extend the service life of the battery.
- Do not charge the battery for more than 10 hours to avoid overcharging and damaging the battery. After the light turns GREEN, the charger is in the state of trickle electric current and will fill slowly to attempt to maintain the state of charge. If you are going to be out for a long time, you should disconnect the charger, especially in hot weather.
- The charger will become warm during charging, so keep the charger away from any heat sources. Please always keep the charger dry and clean. The electronics inside contain high voltages, so never disassemble the charger by yourself.
- After charging, please pull the input plug out of the electrical outlet first, and then pull out theout put connecting a plug from the battery case. Do not let the charger charge the battery or be left connected for a long time, as it may damage the charger and cause a fire.
- While charging, please keep it the charger and battery out of the reach of children. Do not put anything on top of the charger when use, and prevent any liquid, metal or metal fillings from coming into contact with the charger.
- You can also remove the battery from the bicycle and then charge it. You should lift the saddle with the lever that is underneath it, which will enable you to remove the battery. Before you do this, you will have to unlock the battery with the ignition key. When you finish charging, replace the battery. To replace the battery, insert the battery along with the slide bracket and then lock the battery with the ignition key.
- Do not touch the two poles in the battery case with your hands when the battery is removed for charging. The charging connector poles cannot be touched with any metal or any other material that conducts electricity, otherwise, it may cause a short circuit.
- If you don’t ride your bike for a long time, the battery should be charged at least one time per month. This will ensure the battery life. DO NOT use in the state of low battery capacity. Do not leave your battery in a fully discharged state for long periods of time. The battery will continue to
self-discharge, resulting in damage.
- Avoid any contact with water when charging your battery. If a plug or socket gets wet, dry it completely before using.
- When charging, if there is a peculiar smell or the temperature is extremely high, please stop charging immediately and contact us.
When storing the batteries for a long period of time:
Charge the batteries at least every 30 days to avoid capacity loss. Batteries slowly self-discharge when unused over a long period. If the battery cells are left at a critically low charge state, the lifespan and capacity will be permanently reduced.
Always disconnect the charger from the mains electrical supply and battery before storing the battery. Avoid storing batteries in extreme temperatures, whether hot or cold. The recommended battery storage temperature is between 0 and 25°C (32 to 77°F). Avoid exposing batteries to temperatures at or above 40°C (104°F) for extended periods.
Batteries are best kept in a cool, dry place. Do not allow batteries to accumulate condensation, as this may cause shorting or corrosion.
The tyres must always be inflated to the correct pressure (as specified on the tyre sidewall) before every ride. Riding the bicycle with either too low or too high pressures will affect bicycle performance, may affect effective electrical assistance range, and may render the bicycle as dangerous. Use an accurate
pressure gauge when checking pressures.
Before carrying out any sort of maintenance, turn off the power switch and remove the ignition key.
Do some test riding and check the unit is riding normally and safely. Always keep your bike clean. For the battery poles, when dirty, clean them top prevent reduced efficiency or burnt poles. Your E-Bike should undergo an annual check-up. This will keep it in good working condition.
Adjust chain tension:
The chain may loosen after using the bike for a certain period of time, so please adjust the chain when necessary:
Loosen the bolts on the rear shaft, if the chain is loose, please adjust the Chain Bolts on both sides in clockwise until correct. If the chain is too tight, adjust the bolts using counter-clockwise rotation. Keep the crank gear and wheel gear aligned. If you are not experienced or confident, contact a bike specialist.
Adjusting the brakes:
Correct brake adjustment will make the controls easier and offer greater safety.
The brakes are adjusted in a similar fashion to any standard bicycle. It is important for the brakes to work correctly and that the electric cut-off devices to be in working order (Electric cable to the brake levers).
Once the brakes have been adjusted, make the wheels turn to ensure there is no binding and check that when either of the brake levers is pulled, the motor stops working.
For a long service life the following parts of your E-Bike should be regularly lubricated every half year:
- Front axle
- Rear axle
- Front fork and other rotation parts.
For electrical parts, you do not need to lubricate them because they are lubricated in the factory. If you find anything wrong, please go to a bicycle specialist or contact Fortis.
The bike should be cleaned with a damp sponge, taking special care not to get electrical parts wet (Battery connection, motor (rear axle), electric cables, handlebar controls, etc.). Dry with a cloth. When cleaning your electric bike, do not use a steady direct stream of water from a hose. Use a cloth to avoid
short-circuiting any electrical components. Your electric bike has a durable finish and does not need to be waxed. Clean with a mild detergent and buff to restore its original shine if needed.
For safety, longest possible service life and reliability, maintain the bicycle properly. Use the maintenance schedule below for guidance. It is very important that you check certain systems and components before each and every ride. The proper condition and function of these systems is critical to your safety.
