First use


Write down the number on your battery key

It's a good idea to write down the number on the key that comes with your bike to open the battery compartment.

In the event you lose your key, you can order a new one using that number at the link below.

Inflating your tyres

The average recommended air pressure for the original inner tubes that come with your bike is 1.6 bar.

If you're looking for more comfort and grip AND/OR if you weigh under 70 kg, you can reduce the pressure by 10%, but don't go below 1.4 bar (the minimum recommended pressure). Bear in mind that reducing tyre pressure increases the risk of punctures when riding on rough terrain.

For a tubeless mount, you can reduce the air pressure to 1.2 bar.

You should check the pressure of your tyres regularly.


Bedding in your brakes

When you buy a new bike, the brake pads and discs are also brand new and their initial braking performance is low.

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 "freeze up".

To prevent this from happening (which could make them unusable) and to ensure that your brakes work as expected, we recommend that you bed them in.
This takes about 10 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.

How to convert your wheels to tubeless

To reduce the risk of your inner tube being punctured or pinched, you may want to consider making the wheels on your MTB "Tubeless".
Your new bike already comes with waterproof rim tape on the rims, but you'll need to buy some TUBELESS READY tyres.

You'll also need:

- A pair of TUBELESS valves

- Puncture sealant:

The rest is a piece of cake! Simply follow the step-by-step instructions below. Or if you prefer, watch the instructional video.

1. Remove the wheel.

2. Remove the tyre and inner tube from the wheel.

3. Insert a tubeless valve through the rim hole (from inside the rim).

4. Apply (puncture proof) tyre sealant.

5. Mount your new tubeless ready wheel onto the bike.

6. Inflate the tyre quickly and fully to ensure that it sticks to the rim.

If it seems too tricky, just visit your nearest Decathlon workshop and ask them to do it for you.

Determining the right settings for your fork

Your ROCKSHOX 35 GOLD RL fork needs to be adjusted based on your cycling style, terrain and personal preference, but most importantly, based on your weight.

To find out the recommended pressure and rebound for your fork, click the link below. You'll be asked your weight in full kit (with helmet, shoes and hydration backpack) and the model of your bike: an E-MTB.

The app will then calculate the recommended pressure (in psi) and the rebound in number of clicks starting from a fully screwed-in position (clockwise).

The pressure determines what's known as the sag, which is the percentage that the suspension drops into its travel when you get on it and lift your feet. For a softer, more comfortable ride, you'll want a high sag (between 30% and 35%). For a faster, more competitive ride, you'll want more firmness and less sag (between 20% and 25%).

The rebound dictates the speed at which the suspension returns to its original position after damping an impact. The faster the rebound the more comfortable the bike but the more tiring it is to handle it. We recommend adjusting the rebound based on your physical fitness level and steering abilities. The rebound dial can be found underneath the fork's right blade.

Now that you've figured out the recommended settings for your fork, check out our article on "ADJUSTING YOUR FORK'S SAG".

First use
Adjusting your fork's sag

Once you've figured out the right settings for your fork, you'll need an extra pair of hands and a high-pressure pump designed for suspension systems. Since the fork is equipped with a Schrader valve, you can use a standard pump as long as it is high pressure and precise.

Check out our video to learn how to adjust your fork's sag.

NB: The valve's cap is there to protect the valve from dust. It doesn't do anything to retain the pressure. So there's no point doing it up too tight!

Adjusting the sag on your shock

To make your mountain bike behave predictably, your fork's sag should correlate with your shock's sag.

SRAM recommends inflating your shock based on your weight in pounds: one pound is equal to one psi.
Multiply your weight (in full kit) in kilogrammes by 2.2 to get your weight in pounds. So if you weigh 73 kg in all your kit, you'll be 160 pounds (73 x 2.2) and will need to set your shock to 160 psi.

Click the link below to learn more about adjusting your shock's sag.

NB: The valve's cap is there to protect the valve from dust. It doesn't do anything to retain the pressure. So there's no point doing it up too tight!

Calculating your battery range

On its website, Bosch has set up an app to calculate your battery's range based on how you use it.

If you're not sure you have enough battery life for your ride, you could use this simulator by indicating your use of the power modes, your total load weight, pedalling cadence, the components on your MTB, and by entering information about the terrain.

How to mount/remove your battery

To remove the battery from the frame, remove the lock cap on the battery compartment, then insert and turn the key in the lock. The battery is now unlocked. On the top of the battery is a small latch which you can press to release the battery. The battery can now safely be removed.

To put the battery back into the frame, insert the bottom part of the battery into the compartment then push the top of the battery into the compartment until you hear the "click" of the latch. The battery is now locked in place. You can now close the compartment and lock it using the key.

The right equipment in case of a hiccup

Don't forget to take the essentials with you in the event of a flat tyre, broken chain or other mishap while mountain biking.
Following are some products that can be of great help should you encounter a mechanical misadventure.

Have a problem?


Your battery won't charge


Make sure that the charger you are using is the original Bosch charger.
Plug the charger into the battery as well as into a mains plug.

The battery has a temperature sensor that prevents recharging if the temperature falls outside the allowed range of 0°C to 40°C. If the battery temperature is outside of this allowed range, three of the five LEDs will blink. Unplug the battery charger and wait until its temperature once more falls within the allowed range.
If a battery malfunction is detected, two LEDs will blink. Please visit a Decathlon workshop to run a diagnostics check on your battery.

The battery charge level is indicated using five LEDs. Each LED represents 20% of a full battery charge. When the battery charge is below 5% all of the LEDs will be off; however the battery level can still be displayed on the console display.

A fully depleted battery takes 8.8 hours to recharge using the compact charger, 4.9 hours with a standard charger, and 3.7 hours with the fast charger.

The connectors on both the charger and the battery must be clean. There should be no dirt preventing contact between the battery and its charger.

Please visit one of our Decathlon workshops to have them checked and repaired.

The screen is showing an error code

The screen on your Bosch Purion may display an error code.

A full list of malfunction codes can be found at the link below along with steps to take to resolve each indicated issue.

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 follow the recommendations for using and storing your bike.
Your electric bike's range depends on a number of factors:
> THE BIKE LOAD: The range will be reduced if the bike is carrying too much weight.
> THE TERRAIN TYPE: The range is reduced on climbs.
> THE TYRE PRESSURE: The battery will last longer with tyres that are correctly inflated.
> THE OUTSIDE TEMPERATURE: The range is reduced in colder weather (up to -50%).
> THE POWER ASSIST MODE: We recommend selecting a lower power assistance mode when the battery charge is low.

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


Your wheel is buckling after several rides

When you take your new bike out for a ride for the first time, a lot of parts can shift and fall into place.

One such part is the spokes, which can sometimes be heard creaking. This is caused by the residual twist from assembly.

Your wheels should not be buckled in any way at all. If they are, let your local Decathlon workshop know when you take your bike for its free service (six months after purchase) so that they can adjust it for you.

Your gears are not shifting properly

There are several things you can do to ensure your rear gears shift properly:

1. Check the cable and its housing ends:
1a. Housing ends that are out of position can obstruct the derailleur cable when it is being pulled and prevent the gears from shifting smoothly. If a housing end is out of position, push it back into place.

1b. If the derailleur does not move when operating the grip shifter, it's likely that the cable or its housings have seized up. You will need to have the cable and housings replaced.

You can bring your MTB to a Decathlon workshop to have your cables and cable housing replaced.

2. Check that the derailleur dropout isn't bent:
A bent hanger causes the derailleur to be out of alignment and therefore unable to function correctly. Stand behind your bike and check the alignment of the derailleur.

If the dropout is twisted or broken, take your bike to a DECATHLON workshop to have it replaced.

REMEMBER: You can have all the settings on your bike checked for free in the first six months following the date of purchase.

NB: If you regularly ride your MTB in wet or muddy conditions, or if you regularly wash your bike with lots of water, then your cables and cable housing will need to be replaced more frequently. Washing your bike using a high pressure hose is highly discouraged as it can push dirt and dust into the cable housing.

Lost key

If you have lost both keys and don't have the key number, please visit a Decathlon workshop to have the lock changed. You'll be given two new keys to go with the new lock.

If you have lost one of the two keys, you can have a copy made by any locksmith, using the first key as a model for the second one.

If both keys are lost but you have the number written down from either key, you can order a replacement key by clicking on the following link.


Maintaining your mountain bike

How to clean your stilus e-am

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 mountain bike, it is important to leave the battery on the bike. It will help prevent water from getting into the motor.
Do not use a pressure washer as water could get into the ball bearings and permanently damage the electrical components.

How to store your stilus e-am correctly

It is essential to properly store your mountain bike to improve its lifespan, particularly if it is an electrical assistance bike.

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

For winter storage, we have a few other tips to add:
> Switch the derailleur to the smallest cog to release tension on the cables.
> Charge the battery to between 30% and 60%.
> You can coat your bike in a thin layer of Vaseline oil, particularly 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 its frame to reduce pressure on the tyres and prevent any fissures.
> The best way to store your bike is to hang it upside down so that the oil in the fork blades drops down onto the plungers. This will increase your fork's lifespan!

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.

Improving battery lifespan

Bosch batteries are among the most durable on the market, with a lifespan of about 30,000 km. That means that for a cyclist riding 150 km a week, the battery should last 3 to 4 years, providing it is properly cared for.

To make sure your battery lasts as long as possible, we recommend:
- Reducing your use of it (a mountain bike is not a scooter!)
- Charge your battery in temperatures between 10ºC and 20ºC and never in temperatures higher than 30ºC. (Also, use the original charger and make sure it is in good condition.)
- Store your bike with the battery charged to between 30% and 60% (Don't continue to leave the battery plugged in once it is fully charged, and don't store your bike with the battery depleted.)
- Park your bike in the shade or in a cool room.

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

Check your bike's software version

To check your bike's software version using the Bosch Purion console, first turn the console off, then simultaneously press the + and - buttons and hold them down briefly.
Then press the Start/Stop button. The software versions will be displayed. You may want to write them down for easy reference.

DISPL. is the software version of the display.
DU is the software version of the motor.
Bat. is the software version of the battery.

You can then compare these against the latest version numbers on the Bosch website to check whether your software is up-to-date.
