Our team of enthusiasts designed this electrical assistance bike (EAB) for easier city riding: gain comfort and ride effortlessly! Get a helping hand for your urban rides! With its pedalling sensor and battery life up to 70 km, this EAB helps you as soon as you've made a half turn of the pedal.
It's an electrical assistance bike. That means it's entirely possible to ride without this assistance.
Of course, the extra weight of the motor system will make cycling a little harder.
When your battery wears out, take it to your local Decathlon store, which will send it to a specialist recycling facility.
You'll find a list of frequently asked questions in the "Got a problem?" section which should help you resolve any problems you may have with your ELOPS 900 by yourself.
Alternatively you could email one of our specialist technicians who will answer your questions and help you resolve any problems. To do so, please use this form.
You can also visit one of our Decathlon workshops where our cycling experts will take a look at your bike.
You should store your battery somewhere cool (between 10°C and 25°C) and dry, out of direct sunlight.
To avoid deep discharge, which may cause it to malfunction, do not store the battery when empty (1 flashing LED).
Remember to recharge the battery (even when not in use) at least every three months in order to avoid a deep discharge, which could affect the battery's capacity.
If you're storing your battery for a long period (more than 3 months without using it), remember to put the battery in standby mode so that it's easier to store and doesn't need recharging regularly.
Yes. The ELOPS 900 bike is an electrical assistance bike.
This assistance is only triggered when the user pedals (a motorised system that involves no pedalling is considered to be a moped, with usage restrictions and much stricter safety rules).
A pedalling sensor near the chainset transmits the information to the bike's on-board computer, which triggers the motor.
The bike's electric motor cuts out instantly when you brake or stop pedalling.
Turning the pedals again will restart the motor so that you will benefit from the bike's electrical assistance once again.
The battery is designed to be used when it's raining but it shouldn't be submerged in water or washed with a pressure washer.
The same is true for the display and the other components and electrical cables.
Nevertheless, we recommend sheltering your bike as much as possible when you're not riding it.
Standby mode enables the battery to be stored for a long period (1 year maximum) without recharging or reducing the battery capacity.
To switch the battery to standby mode, hold the battery button for 10 seconds until the battery's LEDs turn off.
Charge the battery with its charger to wake it back up.
You can buy a new battery from your local Decathlon workshop.
Contact your workshop to find out if they have the part you need in stock and how long it will take to arrive.
To change from km/h to mph or vice-versa, find the settings by long pressing the "SET" button.
Units can be selected in the SET 3 setting.
Walk mode is an electrical assistance mode that helps you move your bike when you are walking alongside it. It can be very useful, particularly when taking your bike out from a parking area with a slope.
Walk mode lets you push your bike effortlessly.
To activate this mode, switch the control screen on by holding down the On/Off button. Then hold down the "+" button. Be careful: the bike will begin to move at a constant speed of 6km/h.
Do not use this mode whilst on the bike. This may damage the motor.
It takes six hours to fully charge the battery after it has been completely drained.
Your bike is compatible with the THULE Europower bike rack available in Decathlon stores.
This bike rack can hold up to two electric bikes.
Your bike is compatible with the GROOVY baby seat sold in Decathlon stores.
The bike turns off automatically after a few minutes if it isn't being used.
The battery is equipped with a standby mode that enables it to be stored without being charged regularly.
Once set to standby mode, the battery can then be safely stored for up to 1 year without charging or affecting the capacity.
A battery stored without being set to standby mode needs to be charged at least every 3 months to prevent the battery capacity deteriorating.
No, it doesn't have a dynamo. Some systems let you charge the battery as you ride or brake, but this doesn't generate much power. You'd have to ride several dozen kilometres to generate 1 km of additional power.
Yes, the charger is designed to be connected round the clock.
When the battery is fully charged, the charger stops charging but stays connected to the power.
Your battery is guaranteed for 2 years or 500 cycles (1 cycle = 1 charge + 1 full drain).
Having the right tyre pressure is particularly important on an electric bike. The wheels have a lot of weight on them because of the combination of the motor and bike.
To minimise the risk of getting a puncture and to increase your battery life, your tyres should be between 3.5 and 5 bars.
No. Lithium-ion batteries have no memory effect and can therefore be charged at any time.
We recommend charging your battery regularly to keep it working well.
To reset the kilometre counter (TRIP) to zero, once the screen is on, hold down the " - " button on the command screen for 10 seconds.
Your electric bike's battery life depends on numerous factors:
> THE BIKE'S LOAD: The battery life will be shorter if the bike is overloaded
> THE TYPE OF TERRAIN: The battery life will be shorter going uphill
> THE TYRE PRESSURE: The battery life will be better with tyres inflated to between 3.5 and 5 bars.
> THE OUTSIDE TEMPERATURE: The battery life will be shorter when it's cold outside
> THE ASSISTANCE MODE USED: It is advisable to reduce the power assistance mode when the battery charge is low
> YOUR PEDALLING CADENCE: You need to pedal if you want to go further
> WHETHER YOU FOLLOW THE BATTERY CHARGING AND STORAGE INSTRUCTIONS PROPERLY
For the ELOPS 900E, the battery will last for between 40 and 70 km. Taking good care of your bike will ensure that the battery lasts as long as possible.
The lock can be replaced at your local Decathlon workshop.
Contact your Decathlon workshop to find out if they have one in stock and how long it will take to arrive.
1. Check that there isn't any dirt in the way of the connection
Your battery charger's connectors should be clean and there should be no dirt preventing contact between the battery and its connector.
2. Check the battery > charger > mains socket connection
> Make sure the charger you are using is the one provided by Decathlon
> Connect the charger to the battery and a mains socket.
Orange LED = the battery is charging
Green LED = the battery has finished charging
Flashing LED = Charging problem
A completely drained battery will take 6 hours to charge fully.
If the problem persists, contact us or visit one of our Decathlon workshops.
1. Check that the battery is well charged
If the battery is almost empty, it may cause a jerky feeling before it goes completely flat.
> Press the battery button
> Check that at least one LED lights up
> If none of the LEDs light up or the first or second LEDs are flashing, recharge the battery
2. Check that the battery is clean, properly attached and locked in place
> Check that the battery's connectors and holder are clean and in good condition.
> The battery should be pushed all the way into its holder
When you push it in, it will click to indicate that it is correctly in place.
Lock the battery and remove the key.
3. Check the connectors on the pedalling sensor (the thinnest cable)
> To do this, open the rip-tab cable cover behind the saddle and find the pedalling sensor connector (the thinnest cable).
> Disconnect the pair of connectors
> Check that the pedalling sensor connectors are in good condition and correctly pushed in. Re-insert the connectors if necessary.
4. Check that the pedalling sensor on the left of the bike, on the other side to the chainset (by the left crank), has not slipped onto the bottom bracket.
If it has slipped against the crank, gently move it back up against the frame.
If it won't stay in position, apply a blob of glue to the back of the sensor and press it against the frame.
1. Check the tyre pressure
> The tyre pressure determines how efficiently your electrical assistance works. Before each ride, make sure your tyres are inflated to between 3.5 and 5 bars.
2. Make sure you don't overload your bike
The electrical assistance kicks in after several turns of the pedal and needs assistance mode to be activated.
If your electrical assistance still isn't turning on, follow these steps:
1. Check that the battery is well charged
> Press the battery button
> Check that at least one LED is turning on
> If one of the LEDs is blinking, recharge the battery by connecting it to its charger and a socket
2. Check that the battery is clean, properly attached and locked in place
> Check that the battery's connectors and holder are clean and in good condition.
> The battery should be pushed all the way into its holder
When you push it in, it will click to indicate that it is correctly in place.
Lock the battery and remove the key.
3. Check all of the bike's connectors: brakes, motor, console, pedalling sensor, controller (controller = central processing unit of the electrical kit. It is located just behind the battery, on the pannier rack)
To access most of the connectors, you'll need to open or slide off the neoprene cover that's protecting the electrical cables. The motor's connector is the only one that's not covered.
HOW TO CHECK THE BIKE'S CONNECTIONS:
There are two types of connection on your bike: "screw-in" connections and "push-in" connections.
Screw-in "connections"
For ""screw-in"" connections, which you can recognise from the two metal rings, you will need to unscrew both rings in order to disconnect the cables. Be careful not to lose the small plastic washer between the two rings when you unscrew them.
Once disconnected, check that each connector is clean, then reconnect.
To do this, position each male and female connector opposite each other, then align the indicator arrows before pushing them back in.
Tighten the two metal rings as far as they'll go in order to secure the connections.
Push-in "connections"
The male connector is simply pushed into the female connector. Check that both connectors are fully inserted, and push them in more firmly if necessary.
4. Test the in electrical assistance
> Turn on the screen by holding down the On/Off button
> Get on your bike and pedal (you'll need to turn the pedals several times to trigger the electrical assistance).
If the problem persists, submit a support request or visit a Decathlon workshop.
1. Make sure you are using and storing it as recommended
Your electric bike's battery life depends on various things:
> THE BIKE'S LOAD: The battery life will be shorter if the bike is overloaded
> THE TYPE OF TERRAIN: The battery life will be shorter going uphill
> THE TYRE PRESSURE: The battery life will be better with tyres that are inflated to between 3.5 and 5 bars.
> THE OUTSIDE TEMPERATURE: The battery life will be lower in cold weather (up to 50% less)
> THE ASSISTANCE MODE BEING USED: We recommend reducing the assistance when the battery is low.
> THE PEDALLING CADENCE: You need to pedal if you want to go further
> WHETHER YOU FOLLOW THE BATTERY CHARGING AND STORAGE INSTRUCTIONS PROPERLY
For the ELOPS 900E, the battery will take you between 40 and 70 km. Taking good care of your bike will ensure that the battery lasts as long as possible.
2. An old battery may lose some performance
Its battery life will therefore be shorter. Visit your Decathlon workshop to give your battery a check-up.
To switch on the Elops 900E's screen, hold down the "ON / OFF" button.
If the screen still doesn't light up, follow this procedure:
1. Check that the battery is well charged

2. Check that the battery is clean, properly attached and locked in place
> Check that the battery's connectors and holder are clean and in good condition.
> The battery should be pushed all the way into its holder
When you push it in, it will click to indicate that it is correctly in place.
Lock the battery and remove the key.
3. Check that the cable linking the console to the controller is connected (the controller is the central processing unit under the pannier rack, just behind the battery)
> Open the rip-tab cable cover that you'll find between the pannier rack and the saddle.
Check the accessory cable connection (the one with the metal rings).
> To check if the connectors are clean, in good condition, and correctly inserted, unscrew both rings on either side of the black washer.
> Check that each connector is clean and in good condition
> Reconnect everything properly. To do this, position each male and female connector opposite each other, then align the indicator arrows before pushing them back in.
> Tighten the rings as far as they'll go in order to secure the connections.
4. Check that the display is connected
> At the front of the bike, slide the neoprene cover off the screen to reveal the pair of connectors for the screen (black).
> Do the same as before to check the console's connections.
5. Turn the screen on by holding down the On/Off button
If the problem persists, submit a support request or visit a Decathlon workshop.
New batteries are carefully stored so that they won't wear out.
The first time you use your battery, you should connect it to its charger and plug it in to a socket to get it working.
> 1st LED is flashing: The battery is almost empty and needs to be charged. Plug it into its charger and connect to a mains socket to charge it.
> 2nd LED is flashing: The battery is in ""protection mode"" due to being mishandled or after a long period without being charged. Plug it into its charger and a mains socket as soon as possible to recharge it, which will take it out of protection mode
> If there is another flashing LED or several flashing LEDs, the battery is faulty. Take your battery to a Decathlon workshop for full testing.
The electrical assistance should automatically cut out when one of the brake levers is squeezed.
If this doesn't happen, check that the connectors on both brake levers are in good condition and properly connected.
> Slide down the two neoprene cable covers at the front of the bike to uncover the brake connectors (yellow connectors)
> To check whether the connectors are clean, in good condition and correctly pushed in, unscrew the two rings either side of the black washer.
> Check that each connector is clean and in good condition
> Reconnect everything properly. To do this, position each male and female connector opposite each other, then align the indicator arrows before pushing them back in.
> Tighten the rings as far as they'll go in order to secure the connections.
If the problem persists, submit a support request or visit a Decathlon workshop.
Err 1 / Err 6: POWER ANOMALY
> Charge the battery. A full charge will take 6 hours.
Err 3 / Err 4 / Err 7: MOTOR ANOMALY
> Find the motor connection
> Check that the connector is in good condition and correctly pushed in. Re-insert it if necessary.
> Do the same for the cable that links the motor to the controller (the bike's brain, located behind the battery).
Err 5: BRAKE SENSOR FAULT
Check that the two brake lever connectors are in good condition and correctly inserted.
> Slide the two neoprene cable protectors down to uncover the brake connectors (yellow).
> To check if the connectors are in good condition and correctly inserted, unscrew both rings on either side of the black washer:
> Check that each connector is clean and in good condition
> Reconnect everything properly; To do this, position each male and female connector opposite each other, then align the indicator arrows before pushing them back in.
> Screw the two rings back in place to secure the pair of connectors.
> Repeat for the other brake.
Err 8 / Err 9: CONTROLLER AND CONTROL SCREEN COMMUNICATION ERROR
Controller connection:
> Open the rip-tab cable cover located behind the saddle
> Find the connection for the cable that links the control screen to the controller (with the metal rings)
> To check whether the connectors are clean, in good condition and correctly inserted, unscrew the two rings on either side of the black washer.
> Check that each connector is clean and in good condition
> Reconnect everything; To do this, position each male and female connector opposite each other, then align the indicator arrows before pushing them back in.
> Tighten the two rings as far as they'll go in order to secure the pair of connectors.
Control screen connection
> Slide the neoprene cable protector on the side of the control screen downwards and check the pair of screen protectors (green).
To check if the screen connectors are clean, in good condition, and correctly inserted, unscrew both rings on either side of the black washer.
> Check the condition and cleanliness of each connector.
> Reconnect the connectors; To do this, position each male and female connector opposite each other, then align the indicator arrows before pushing them back in.
> Tighten the two rings as far as they'll go in order to secure the pair of connectors.
Check that the battery is pushed in all the way and remember to lock it in place before each use.
If it isn't pushed in fully or if it shakes around during use (due to it not being locked), it will struggle to connect properly to the rest of the system and data such as the charge level won't be accurately transmitted.
Check that the motor connector is in good condition and properly inserted.
Clean the connector or push it all the way in so that the speed displays normally.
If the problem persists, submit a support request or visit your local Decathlon store for a diagnosis and repair.
The rear wheel hub may be incorrectly adjusted. Follow the tutorial below to adjust your gears correctly.
