ROCKRIDER E-ST 900 WOMEN'S ELECTRIC MOUNTAIN BIKE

With electric bikes, you need to keep a close eye on tyre pressure. The wheels have a lot of weight on them because of the combination of the motor and bike. To reduce the risk of punctures and ensure your bike can achieve its maximum range, we recommend you inflate your tyres to a pressure of between 1.0 and 1.8 bar.

The brake pads and discs on a new bike are new themselves and don't work to their full potential. Hard, continuous braking (on descents, for example) can cause the pads to overheat and "glaze". To ensure that your brakes perform, we recommend you bed them in.  You need to apply each brake firmly around ten times to bed them in properly. The bedding-in process involves getting up to a speed of 25 km/h and then applying just one of the brakes firmly to reduce your speed to 5 km/h, without locking the wheel.

Each button has a separate function, detailed below:

"TOP ARROW" BUTTON                                                                 

> Press and hold down to launch Pedestrian mode.

> Press and let go to switch to Low Boost mode.

 

"BOTTOM ARROW BUTTON"

> Press and let go to switch to High Boost mode.

 

"ON/OFF" BUTTON

> Press and hold down to switch the display on and off.

 

"LIGHTS BUTTON"

 The Rockrider e-ST 900 is not fitted with lights and this button has no specific function. The backlighting on the display is managed automatically.

                                                                                                                                                                                                             

If the lighting indicator comes on, you can switch it off by pressing and holding down the "LIGHTS" button.

 

NAVIGATION JOYSTICK     

This joystick moves up, down, left and right and allows you to switch from screen to screen and browse data.

You can also confirm your choices (languages, reset to zero, etc) by clicking on the joystick. 

The bike turns off automatically after a few minutes if it isn't being used.

With some climbs, there's no option but to get off your bike and push it. Using this mode makes that task less onerous.

Please note that you shouldn't use this mode when riding the bike. Press and hold down the "TOP ARROW" button to launch the mode. The mode deactivates when you stop pressing the button.

 

Do not use Pedestrian mode when you are seated on the bike,as this may damage the motor.

MODE 0 = No electric assistance

MODE 1 = The electric system provides over 40% of your pedal power.

MODE 2 = The electric system provides over 80% of your pedal power.

MODE 3 = The electric system provides over 160% of your pedal power.

MODE 4 = The electric system provides over 320% of your pedal power.

It takes three hours to charge the battery fully (from 0% to 100%).

It's an electric-assist bike. There's nothing to stop you riding without that assistance.

You'll feel the weight of the electric system, however.

Yes, the charger is designed to be connected round the clock.

When the battery reaches full charge, the charger switches off. The LED light on the charger will switch off.

No, lithium-ion batteries do not have a memory effect and can be charged at any time.

We recommend charging your battery regularly to maintain its performance.

No, it doesn't have a dynamo. Some systems enable the battery to charge while cycling or braking but performance levels are very low.

When your battery is worn out, take it to your DECATHLON store, where it will be collected for recycling.

You must store and charge your battery in a cool (between 10°C and 25°C), dry place out of sunlight.Do not store the battery when it is empty or below 10% charge as this may result in deep discharge and irreversible damage to the battery.You should charge the battery (even if it's not being used) at least once every six months to prevent deep discharge and loss of the battery's capacity.

You can buy new batteries from your DECATHLON workshop.Contact your nearest workshop to check on availability and order times.

The range of your electric bike 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.> HOW YOU RIDE THE BIKE: The range depends on how much effort you expend when pedalling.> TYRE PRESSURE: The range increases when tyres are inflated to a pressure of between 1 and 1.8 bar.> OUTDOOR TEMPERATURES: The range is reduced in colder weather.> THE BOOST MODE USED: We recommend reducing the boost mode when the battery is running low.> OBSERVANCE OF THE BATTERY CHARGE AND STORAGE CONDITIONS

1. CHECK THE CONNECTION BETWEEN THE BATTERY, CHARGER AND THE MAINS

 

Check that the charger you're using is the one originally supplied by DECATHLON.

Connect the charger to the battery and a mains socket.

Solid red LED light = the battery is charging.

Solid green LED light = the battery is charged.

Flashing LED light = there is a problem with the battery or charger.

It takes six hours for an empty battery to fully recharge.

 

2. CHECK THAT THERE IS NO RESIDUE ON THE CONNECTORS

The charger and battery connectors must be clean. Make sure there is no residue preventing the charger from connecting with the battery.

 

3. IT MAY BE THE CASE THAT THE LED LIGHTS ON THE BATTERY ARE DEFECTIVE

Drop in at one of our DECATHLON workshops to get it repaired.

THE LAST LED LIGHT IS FLASHING (the one furthest from the battery button).

Your battery is nearly empty and needs to be charged. Connect your battery to the charger.

 

THE FOURTH LED LIGHT IS FLASHING

Undervoltage fault. Your battery has not been charged for a long time. Plug your charger into the mains and connect it to the battery straightaway. If you do not, your battery may go into "deep sleep" and become unusable.

 

ANOTHER LED LIGHT IS FLASHING 

Your battery has suffered a fault of some kind and has malfunctioned. This fault may be temporary or permanent. Go to a Decathlon workshop to have your battery and bike checked.
