PREPARING YOUR MOUNTAIN BIKE
INFLATING YOUR TYRES

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.

BEDDING IN YOUR BRAKES

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.

ADJUSTING THE HEIGHT OF YOUR HANDLEBARS 

Your handlebar is set in the highest position to help keep your back raised, which is the most comfortable position for riding. For improved aerodynamics and more effective pedalling, you can lower your handlebars to lower your body. This will cause you to lean forward and adopt a racing position. Follow the steps in this video to move the headset spacers below the stem and lower the handlebars on your bike.

LOW OR REDUCED RANGE

1. Please follow best practices when it comes to usage and storage. 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. > 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 (by up to 50%). > THE BOOST MODE USED: We recommend reducing the boost mode when the battery is running low. > OBSERVANCE OF THE BATTERY CHARGE AND STORAGE CONDITIONS.   2. Old batteries do not perform as well as new ones They offer reduced range. Head to your nearest DECATHLON workshop to have your battery checked.

> MECHANICS
A WHEEL IS BUCKLING AFTER A FEW RIDES
WheelBuckling

When you take your new bike out for a ride for the first time, a lot of parts move around and fall into place.   You'll hear the spokes on your wheels creak because of the residual torsion in them. Your wheels should not buckle in any way at all. If they do, then make the most of the free check-up available to you within six months of purchase and call in at one of our DECATHLON workshops to have them repaired free of charge.

YOUR GEARS ARE NOT SHIFTING PROPERLY
E-ST 900 drive train

There could be several reasons why your gears (cogs) are not shifting correctly.

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

2. The cable and housings may have jammed up.
If the smallest gears (cogs) do not move down, if the derailleur doesn't move even when the gear shifter is operated, then the cable and the housings have jammed up. They need to be replaced. You can head to a DECATHLON workshop or replace it yourself with the help of this video.

3. Take your mountain bike to a DECATHLON workshop to have the derailleur adjusted. 4. You should also check that the derailleur dropout is not twisted.

YOU'VE LOST A KEY

You can have a new key cut at a heel bar/locksmith. If you lose both keys, go to your nearest DECATHLON workshop to have the lock changed. You'll be given two new keys to go with the lock.

THE BATTERY
HOW LONG DOES IT TAKE THE BATTERY TO CHARGE?
Charger

It takes six and a half hours to charge the battery fully (from 0% to 100%).

CAN YOU RIDE WHEN YOUR BATTERY IS FLAT?

It's an electrical assistance bike. That means it's entirely possible to ride without this assistance.

However, you may well notice the additional weight of the assistance system.

CAN YOU LEAVE YOUR CHARGER CONNECTED TO THE BATTERY EVEN AFTER IT HAS FINISHED CHARGING?

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

When the battery is fully charged, the charger stops charging. You can tell when it is charged because the LED will turn off.

SHOULD YOU WAIT UNTIL YOUR BATTERY IS COMPLETELY FLAT BEFORE CHARGING IT?

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.

DOES THE BATTERY CHARGE WHILE CYCLING?

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.

WHAT SHOULD YOU DO WITH THE BATTERY WHEN IT WEARS OUT?

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

HOW SHOULD YOU STORE YOUR BATTERY?

You must store and charge your battery in a cool (between 10°C and 25°C), dry place, out of direct sunlight. Do not store the battery for long periods if it is empty or below 10% charge as this may result in deep discharge and damage 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.

WHERE CAN YOU BUY A REPLACEMENT BATTERY?

You can buy new batteries from your DECATHLON workshop.

Contact your nearest workshop to check on availability and order times.

WHAT IS THE RANGE OF THE ROCKRIDER E-ST500 V2?
e st 500 v2 battery life

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

WHAT IS THE LIFETIME OF YOUR BATTERY? WHAT IS THE LIFETIME OF YOUR BATTERY?

The warranty on your battery is for 2 years or 500 cycles (1 cycle = 1 full charge + 1 full discharges, or two 50% charges + two 50% discharges). Up to these 500 cycles, we guarantee that the battery life will always be at least 80% of a new battery's life. After 500 cycles, the battery will still work but its range will drop off faster. Given the average range of 60 km when the battery is 100% charged, that means you can cover more than 25,000 km.

PRODUCT MAINTENANCE

Regular maintenance is important if you want to keep your bike working efficiently for as long as possible, so we've put together some maintenance tips to help you.

1. Before each ride, make sure your tyres are inflated to 1.8 bar.

2. Charge the battery fully at least once every 6 months.

3. Store the battery in a dry place, at a moderate temperature, and out of the sun.
