Finishing your bike's assembly

If you purchase your bike in a Decathlon store or have it delivered to a Decathlon store, the sales assistant will give you the bike 100% assembled.

If you order your bike on the Decathlon website and have it delivered to your home, you'll need to finish a few very simple assembly steps with the help of the video above.

Connecting your phone to your e-bike

You can connect your smartphone to your electric bike via Bluetooth. This gives you the full e-bike experience, including:

- Assistance mode usage stats
- Better battery range management
- Your route map and all your ride metrics (downloadable straight to Strava)
- Updates for your electronics
And much more!

To connect your phone to your e-bike, you'll need to download the DECATHLON RIDEapp.
The process is explained in the app.

The DECATHLON RIDE app is compatible with the following operating systems:
- For Apple devices: iOS 8 and greater
- For Android devices: Android 7 and greater

First use
Bedding in your brakes

When your bike leaves the shop with its shiny new brake pads and discs, their braking power is weak. A sharp prolonged braking action (for example, during a descent) with brakes that have never before been used can cause the pads to overheat and to "glaze over".

To ensure that your brakes perform, we recommend that you bed them in. This takes about 10 gentle braking actions per brake. For each braking action, apply a single brake to slow the bike down from about 25 km/h to 5 km/h without fully blocking the wheel. Repeat with the other brake.

Getting to grips with the screen

The start/stop button located above the display turns the screen on and off. Use the up arrow ˄ and the down arrow ˅ on the remote control to switch between the different assistance modes. Mode 0 is where the motor is deactivated and mode 4 is the most powerful mode, with 280% assistance.
In other words, if you generate 100W with your legs, the motor adds 280W for a total of 380 W!

In each assistance mode (except mode 0), you can hold down the ˄ button to launch walk mode, which helps you to push your bike along while walking.

The button under the remote control corresponds to Boost mode: as long as you keep the button pressed, the mountain bike switches to the most powerful assistance mode to help you get through a temporary difficulty.

Press the up arrow ˄ and down arrow ˅ on the left of the screen to scroll through the different information: distance covered, total distance, ride time, cadence, estimated remaining battery, electric power and user power.

You can charge your phone or GPS computer by plugging it into the screen with a USB A cable.

The button under the screen opens up the settings menu.

The screen connects to your phone via Bluetooth: Find all the information you need about the connectivity of your AE MTB above.

YOUR BATTERY WON'T CHARGE

1. CHECK THE BATTERY > CHARGER > MAINS SOCKET CONNECTION
Make sure the charger you are using is an original one provided by Decathlon.
Connect the charger to the battery and to a mains socket.
Charger light is red: the battery is charging.
Charger light is green: the battery has finished charging.
Flashing red charger light= the battery or charger has a problem.

2. CHECK THAT THERE IS NO DIRT PREVENTING CHARGING
The charger's and the battery's connectors should be clean. There should be no dirt preventing contact between the battery and its charger.

3. THE LED INDICATORS ON THE BATTERY MAY BE FAULTY
Visit your Decathlon workshop to have them repaired.

ONE OR MORE LEDS ON YOUR BATTERY IS/ARE FLASHING

THE FIRST LED IS FLASHING.
Your battery is almost flat and needs to be charged. Plug your battery into the charger.

THE 3RD LED IS FLASHING
Your battery has tripped because the temperature is too high.


 THE 4TH LED IS FLASHING
Your battery has tripped due to a short-circuit.

THE LAST LED IS FLASHING
Your battery has suffered an abnormal event which has caused it to malfunction. This malfunction may be temporary or permanent. Please visit a Decathlon workshop to have your battery and bike diagnosed.

THE SCREEN IS SHOWING AN ERROR CODE

The screen may display an error code.

All defect codes are catalogued in the electrical user guides. Each code has an action to take to solve the problem.

If the problem continues or you are unable to perform the action, please visit one of our Decathlon workshops for a repair.

LOW OR REDUCED RANGE

1. Make sure you are following the recommendations for using and storing your bike.
Your electric bike's range depends on a number of factors:
> THE LOAD ON THE BIKE: The range will be reduced if the bike is carrying too much weight.
> THE TYPE OF ROUTE: The range is reduced on climbs.
> THE TYRE PRESSURE: The battery will last longer with tyres that are correctly inflated.
> THE OUTDOOR TEMPERATURE: The range is reduced in colder weather (up to -50%).
> THE BOOST MODE USED: It is advisable to reduce the power assistance mode when the battery charge is low.
> FOLLOWING THE INSTRUCTIONS FOR CHARGING AND STORING YOUR BATTERY.

2. An old battery can have reduced performance.
The distance you can travel will therefore be reduced. Visit your Decathlon workshop to give your battery a check-up.

Maintaining your bike

Servicing your bike will keep all of its parts working for as long as possible and ensure you have the most fun when riding. Aside from the aesthetic aspect of having a clean bike, failing to service it can lead to problems, and problems lead to accidents, so you must always check for jammed cables, rust, leaks, premature wear, etc.

Good maintenance is good for your performances, while your bike's parts will also last longer, which means a lower environmental impact.

When you start riding your bike, some components will move slightly.

How to clean your bike

To clean your bike properly, you'll need some bike cleaner, a sponge, and a brush.

Rinse off the bike with a hose and apply the bike cleaner. Next, use the sponge and brush to work the cleaner in. It's essential to give the bike cleaner some time to act before rinsing the bike off.
When hosing the bike off, make sure you do so from a few steps away so as not to damage the mechanical components.
Lastly, dry your bike using a soft, clean cloth.

To wash your electric bike, it is important to leave the battery on the bike. This will protect the leads from water!
Do not use a pressure washer as water could get into the ball bearings and permanently damage the electrical components.

How to correctly store an EAB

It is essential to properly store your EAB to improve its lifespan.

After your ride, we recommend:
> Clean off any mud and sand to prevent your bike from rusting.
> Dry and lubricate your drive train (being sure not to get any on the brakes) to protect it from rust and corrosion.
> Store your EAB in a cool dry place.

For winter storage, we have a few other tips to add:
> Put the derailleur on the small cog to release the tension on the cables.
> Ideally, charge the battery to 60%.
> You can coat your bike in a thin layer of Vaseline, focusing on the spokes and hub, the rims, the handlebar, and the stem. Use a clean cloth, slightly soaked in oil; this will protect the components from dust.
> Hang your mountain bike by the frame to limit pressure on the tyres and prevent possible fissures.

IMPORTANT: Cool does not mean cold! Avoid overly hot or cold temperatures at all costs. Do not store your mountain bike in the sun and be careful of winter freeze.
The garage can be a good solution, as long as it stays dry and does not freeze in winter; otherwise, store it inside your house.

STORING YOUR ROCKRIDER E-ST 900 CORRECTLY
IMPROVING BATTERY LIFESPAN

To improve the lifespan of your battery as much as possible, we recommend:

- Reducing your use of it (an EAB is not a scooter!)
- Charging the battery with the original charger, and ensuring that the charger is in good condition
- Storing your EAB with a charge level around 60% (do not leave the battery plugged in beyond 100% and do not store it totally discharged)
- Storing your MTB in the shade or in cool rooms.

When transporting it, also consider removing the battery from your mountain bike and storing it inside your vehicle.

IMPROVING BATTERY LIFESPAN
CHANGING THE BRAKE PADS

On disc brakes, you need to change the pads regularly. Depending on how heavily you use your brakes, the wear on the pads will be affected.

If you feel a loss of "bite", a loss of performance, or a squeak in your brakes, your pads may be worn out. To be sure, check the thickness of the pad. If there is less than one or two millimetres left, replace it.

CHECKING CHAIN WEAR

You can check how worn your chain is by using a wear indicator. Simply place the indicator's notch between two links and let the other end drop onto the chain. If it fits neatly between two links, the chain is worn and it's important to change it soon, before it damages the cassette and chainring.

We recommend changing your chain when it's 50% worn. Above 75%, you should change the chain, cassette AND chainring, which is why it's best to regularly change your chain: this stops you having to replace your entire drive train.

Try to use all the different cogs on the cassette or a gentler assistance mode when riding. It is very common for users to need to replace their entire cassette because the small cog is worn out prematurely due to an assistance mode that is too often in turbo mode, or because the small cog is too worn compared to the others).
REMEMBER: electrical-assistance bikes need a reinforced chain.
