VAN RYSEL E-EDR AF Shimano 105 Di2 2x12S

Press the button on the top tube for 3 seconds to switch the bike off. The light on the button on the top tube goes out.

The bike is fitted with a GPS bike computer that operates independently to the bike. It communicates wirelessly with the bike and displays the data transmitted by the bike, such as the assistance mode selected, the bike's battery level, the remaining range in km, etc.
See the "BC900 BIKE COMPUTER" section below to find out how it works and to take full advantage of all its features.

With the button on the top tube:

- the button permanently displays the battery level using a colour code; to display the assistance level in use, press the button once, the corresponding colour will light up
- then you can change the assistance level by pressing the button
- each time you press the button, the assistance level goes up
- it is not possible to lower the assistance level, you have to complete "loops" (0->1->2->3->0->1->2->3->...)

Yes, the electrical assistance is only activated if the user pedals.
The bike is fitted with a cadence sensor.This transmits pedalling speed information to the bike's on-board computer, which then activates the motor.
The level of assistance provided can then be adjusted according to the assistance mode chosen (1, 2 or 3). In mode 1, the pedalling force required to reach the same speed is greater than in mode 3.

The assistance level used (0, 1, 2 or 3) is displayed in 2 places:
- the display shows the number of the chosen level (0, 1, 2 or 3)
- the button on the top tube shows the colour corresponding to the chosen level

The recommended pressure is 3.5 to 5.5 bars.
For greater comfort and grip, you can lower your tyre pressure to 2.5 bars.
The minimum pressure is 1.5 bars, the maximum 3.5 bars.

When your bike is brand new, the performance of the brakes is reduced because the pads and discs are new. Continuous heavy braking when first used (e.g. downhill) can lead to overheating and brake pad "glazing".

To avoid this phenomenon, which renders the brakes unusable, we recommend that you run in the brakes. This takes about 10 gentle braking actions per brake. Braking means decelerating sharply from 25 to 5 km/h, but without locking the wheel, using just one brake at a time.

If you can see a thin, shiny layer on the top of your brake pads, this probably means that they're glazed. To avoid having to throw them away, you can deglaze them by sanding them lightly with some relatively fine sandpaper (P120). Remember to wear gloves and a mask when sanding your brake pads. Then simply remount your brake pads and bed them in again.

Yes, the battery is designed to be used in the rain, but it must not be immersed or washed with a high-pressure jet.

The same applies to the display or other electrical components and cables.

Nevertheless, we recommend sheltering your bike as much as possible when you're not riding it.

The bike switches itself off after a few minutes when not in use.

The battery is charged on the bike and is not removable. Important: connect the mains plug to the charger before plugging it in to the bike.
The charger connector is fitted with a one-way plug. It must be correctly oriented to be plugged in. Do not force it, as this could damage it.

No, the battery is not removable. It can only be removed from the bike by your Decathlon shop workshop.

The charger provides a full charge in 5 hours.

Your electric bike's range depends on a number of factors:

> LOADS: The range will be reduced if the bike is carrying too much weight.
> TYPE OF ROUTE: Range is reduced when climbing or on uneven terrain
> TIRE PRESSURE: Tyres inflated to a minimum of 3 bar and a maximum of 3.5 bar will give you greater range.
 > OUTSIDE TEMPERATURE: Range is reduced in cold weather.
> POWER ASSIST MODE: It is advisable to reduce the power assistance mode when the battery charge is low.
> PROPER COMPLIANCE WITH BATTERY CHARGING AND STORAGE CONDITIONS

On average, battery life is:
100km in mode 1
70km in mode 2
40km in mode 3

If you want to extend your bike's range, you can add an extra 216Wh battery to the bottle cage on the frame (range extender).

There are 2 ways to check the battery charge level:

1. The computer shows the battery level in % and the remaining range in km (depending on the level of assistance chosen).
Be careful not to confuse this with the battery level of the computer itself!

2. The colour-coded button on the top tube indicates the battery charge level:
- white: >75%
- green: 50%-75%
- orange: 25%-50%
- red: 15%-25%
- flashing red: <15%

You cannot change the bike's battery yourself.
You can get a new battery from your Decathlon workshop.

Contact your workshop to find out if they have your battery in stock and how long it will take to arrive.

You should store your battery somewhere cool (between 10°C and 25°C) and dry, out of direct sunlight.

You should charge the battery (even if it's not being used) at least once every three months to prevent deep discharge and loss of the battery's capacity.

The warranty on your battery is for 2 years or 500 charge cycles (1 cycle = 1 full charge + 1 full discharge).

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.

We strongly recommend against leaving your battery plugged in when unattended, for example overnight.

For your information: once the battery is fully charged, the charger will automatically shut itself off (the LED indicator on the charger stays on).

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.

It's an electrically-assisted bike, so it's perfectly possible to ride without the assistance. What's more, thanks to an internal freewheel in the motor, you can ride the bike without being slowed down.

When your battery wears out, take it to your local Decathlon store, which will send it to a specialist facility to be recycled.

You can store your battery for up to six months without recharging, without degrading battery capacity. If storing it for longer than six months, you must fully charge it.

The computer does not switch on automatically when the bike is turned on. To switch it on, hold the computer's ON button for 2 seconds.

IMPORTANT! When you switch on your BC900 display for the first time, you need to configure it and pair the bike computer to your electric bike's system. Please follow these steps:

- Download the "Decathlon Connect" app onto your smartphone”

- Go to the "devices" menu and press "add”

The bike is fitted with a MAHLE e-bike drive system (battery, motor and control unit).
MAHLE has developed its own app, which uses BLUETOOTH to connect your bike to your phone.
The app, which is not essential for using the bike, has some useful functionalities that can enhance your user experience:
- battery life
- ride history
- customisation of motor behaviour (operating profile or manual customisation)
- bike info and status
- alerts and notifications
- tutorials

To download the MAHLE app, simply search and click on MAHLE MY SMART BIKE on your phone's app store.

Once you've downloaded it, you need to create a connection profile and pair it with your bike via BLUETOOTH by following the instructions.

To service your E-EDR correctly, you need to have the right tools.

The tyre is the only element in contact with the ground. To minimise the risk of it losing grip, it's essential to choose the right type of tyre and to adapt the pressure accordingly.

On an e-bike, the tyre will greatly affect how long your battery lasts, which is why it's so important to have the right one.

Check out our advice here: 

To make sure your saddle is set correctly, you must make sure it is properly tightened. A loose seat post can easily drop down when you're out and about on your bike.
If you tighten it up too much, however, you run the risk of crushing the seat post and damaging your bike.


The best way to tighten a seat post is to use a torque wrench. It should be tightened to between 6 and 7 Nm.


NB: Do not exceed the maximum height indicated on the seat post.

The chain is a vital part of your bike's drive train. The following are tell-tale signs that you need to change it:
- The chain starts jumping.
- The chain has been on for more than 5,000 kilometres.
- Gear changes are not smooth.

To check your chain use the following tool.

The following are all signs that you might need to change your brake pads:

- You don't have the same responsiveness as when you bought your E-EDR and there's a lack of bite.
- Your bike makes a strange noise when you brake sharply.
- The thickness of the pad is below 0.5 mm.

Although disc brakes are designed to wear out the brake pads and not the disc, the disc will eventually wear out where there is heavy use.

It can be dangerous to ride with a worn brake disc. It could break when braking sharply and hard.

The maximum amount of wear for a disc is around 10% of its original thickness. We strongly recommend that you change it when the wear exceeds that figure.

To ensure your frame lasts longer, grease the bearings and abrasive parts of your E-EDR bike regularly. You should be keeping a close eye on the following:

- Bottom bracket.
- Steerer tube.
- Wheel bearings.
- Seatpost.

New batteries are carefully stored so that they won't be drained to begin with.

The first time you use your bike, you must connect your battery to its charger and plug it into a socket to "wake it up", if the store has not already done so.

If the problem persists and the battery still doesn't turn on, submit a support request or visit a Decathlon workshop.

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 charger.

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.

A completely drained battery will take 5 hours to charge fully.

If the problem persists, please contact us through the contact form, 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:

> LOADS: The range will be reduced if the bike is carrying too much weight.

> TYPE OF ROUTE: The range is reduced on climbs.

> TYRE PRESSURE: The battery life will be better with tyres inflated to between 1.5 and 3.5 bars.

> THE OUTDOOR TEMPERATURE: The range is reduced in colder weather (by up to 50%).

> POWER ASSIST MODE: We recommend reducing the assistance mode when the battery is running low.

> YOUR PEDALLING POWER: You have to pedal in order to move.
An e-bike is still a bike, so you'll need to pick the gear best suited to how you ride it.

2. An old battery may lose some performance
Its range will therefore be shorter. Visit your Decathlon workshop to give your battery a check-up.

Please note that the E-GRVL AFX 35 is an electrically assisted bike with a cadence sensor.

If you stop pushing on the pedals, the assistance will cut out.

If you find it too much of a strain, move up one assistance mode.

The electric assistance will automatically cut off once the bike reaches a speed of 25 km/h; this is not a malfunction.

If your electrical assistance still isn't turning on, if it's jerky or if it cuts out, follow these steps:

1. Check the battery charge

2. Let the system cool down.
In high temperatures, or after a long ride, the electric system may overheat. Allow the bike to cool down and don’t use it for a few minutes before restarting the electric assistance.

3. Select an assistance mode other than 0
If the mode displayed on the screen is 0, the motor will not deliver any electrical assistance.
Select assistance mode 1, 2 or 3.
When you have selected a mode, start pedalling hard.
Select a higher assistance mode (3 is the highest) if the amount of pedalling force needed to engage the electrical assistance is too difficult for you.

If the electrical assistance still fails to engage, please contact us or bring your bike to a Decathlon workshop.

To find out which error it is, please refer to the list of error codes in the user guide.

Are your pedals broken? Do you want to change your pedals to clipless ones? Here's our advice.

NB: please note that the screw thread on the left pedal is inverted and that the pedal thus screws on in an anti-clockwise direction. The right pedal has a standard thread.

Make sure to use the correct tool to remove your pedals as you will need to use some force to unscrew them.

If you suffer a puncture, watch our video tutorial to find out how to change your conventional or tubeless tyre:

The tape on your handlebar will wear over time and you'll need to change it occasionally.

There are several things you can do if your brakes aren't working as well as they used to:

- Use a degreaser to clean the disc.

- Check the brake pads for wear.

- Check the tension of the cable.

If your brake pads are worn, you must change them. Watch the following video tutorial.

If your disc is making a noise:

- Check that your wheel is properly centred. To do this, loosen the wheel and tighten it up again.

- Check that the brake calliper is in the right position.

- Check the brake pads for wear.

- Check the tension of your brake cables.

If your derailleur is no longer responding to your gear changes, you may have to replace the cables and housings on the derailleur.

Since you have electronic derailleurs on this E-EDR, make sure their batteries aren't flat.

Watch our video tutorial to find out how:

If the gears are skipping, you should check the following:

- The wear on your drive train.

- The tension of the cables.

If the problem lies elsewhere, then you should adjust your derailleur.

If the drive train is not working properly and the derailleur hanger is twisted. 

Watch the video tutorial to find out how to change it.

We tell you below how to change your bike chain.

To find out if your cassette is worn just count the number of teeth on it. If the chain jumps or the cassette has more than 10,000 kilometres on it, it's time to change it.

Watch our video tutorial to find out how to change it:

If your battery is faulty, you can change it. However, you will need to take several steps before you can access the battery:

- Remove the fork,
- Remove the chainset and the bottom bracket.

Whenever you need to do something to the battery, we always recommend contacting your nearest workshop.
