RIVERSIDE 520E
Date of la󰘵 update : 16/01/2023

Dear Cu󰘵omers,
Thank you for purchasing a RIVERSIDE electrically-assi󰘵ed bike.
We invite you to read the in󰘵ruction manual to get the mo󰘵 out of your RIVERSIDE 520E
bike.
Never forget that an electrically-assi󰘵ed bike is not a moped. It needs your help to go further,
fa󰘵er and longer.
We sugge󰘵 that you learn how to use your electrically-assi󰘵ed bike in an open area in order
to get used to the feel of the motor kicking in and thus ensure optimum control of your bicycle.
An electrically-assi󰘵ed bike is heavier than a conventional bike (the weight of the RIVER-
SIDE 520E on its own is 22.5 kg). Without power assi󰘵ance, pedalling can be more di󰘲cult.
You mu󰘵 always make sure you are capable of riding the entire journey without assi󰘵ance,
in case your battery runs 󰘱at.
Here is what you need to do to get the mo󰘵 out of your RIVERSIDE power-assi󰘵ed bike.

0. Assi󰘵ance cuts o󰘯 when the speed is above 25km/h. In case of intensive use and in exceptional climatic condi-
tions, assi󰘵ance may be cut o󰘯 to safeguard the whole sy󰘵em.
The power supplied is calculated by the controller «C» according to your pedalling rate and the force applied to the
pedals. According to the mode selected, the controller «C» sends more or less current to the motor «F» to provide
you with the desired level of assi󰘵ance
Power assi󰘵ance does not activate or shuts down in the following situations:
The speed is above 25km/h
You’re not pedalling

MOTOR
The motor «F» of your power-assi󰘵ed bike is a brushless-type motor with mechanical reduction, which means you
can have high torque and less resi󰘵ance (quieter motor). The A-weighted emission sound pressure level at the driver
ears is less than 70 dB(A). Motor power is limited to 250 W maximum.
BATTERY AND CHARGER
Battery properties and warranty
All batteries in our electric bikes use Lithium-Ion cell technology and have no memory e󰘯ect. (the battery can be
recharged at any time; there’s no need to wait until it’s completely discharged).
Recharging the battery after each use is recommended.
Charge the battery to 100% prior to its 󰘰r󰘵 use.
Battery Charger
Battery 36 V / 14 Ah
504Wh
Input: 100-240 V
Output: 42 V
Your battery is guaranteed for 2 years or 500 charging and discharging cycles (1 cycle = 1 charge from 0% to 100% +
1 discharge from 100% to 0% or 1 cycle = 2 charges to 50%) subject to compliance with the proper conditions of use
and 󰘵orage. Never use a di󰘯erent charger to the one supplied by DECATHLON for this bike model. Use of another
charger may damage the battery or cause serious incidents (sparks, outbreak of 󰘰re)
Battery life
The battery life of your electric bike depends on numerous factors:
- The weight on the bike: Overloading the bicycle will reduce the battery life (panniers, baby carrier etc).
- Use: Depending on the human input provided during pedalling, battery life will increase or decrease.
- The type of route ridden: Battery life will drop when cycling uphill.
- Tyre pressure: Battery life will be better with tyres in󰘱ated between 4 and 5 bar.
- Outside temperature: Cold weather reduces battery life.
- The mode of assi󰘵ance used: It is advisable to reduce the power assi󰘵ance mode when the battery charge is low.
- The selected transmission ratio: On 󰘵eep slopes, it is advisable to choose the right gear to reduce the e󰘯ort re-
quired from you and the motor.
- Complying with the proper conditions for charging and 󰘵oring the battery: For a cycli󰘵 weighing 75kg, adhering to
these be󰘵 practices, and cycling in light wind using mode 1, the battery range of the RIVERSIDE 520E is e󰘵imated to
be around 100km.

SAFETY INFORMATION
Please note: this bike is designed for TREKKING use.
Mountain bike use is inappropriate and should be avoided
(Risk of accident and cancellation of the bike guarantee if you do not comply
with this condition)
Warning, in the event of wheel removal, you mu󰘵 ensure the direction of
rotation of your wheel is correct.
Before each use you mu󰘵 make sure that your brakes and electric sy󰘵em
are working properly
The weight, power, manufacturing year and maximum speed are indicated on
your bicycle’s frame.
As the weight of your bike with electric assi󰘵ance exceeds 15kg, we recom-
mend that 2 persons transport it.
Always wear a helmet when riding your bike.
These electric bikes are designed for persons aged 14 and over.
Maximum weight allowed on the bike: 120 kg in total (including accessories)
Never modify the bike’s components or electrical sy󰘵em! Any change is
dangerous and prohibited by law.
If a modi󰘰ed bike breaks down or is damaged, Decathlon will in no case take
care of repairs (warranty cancelled)). You will also be legally responsible for
any accident that arises with the bike.
Caution: in rain, fro󰘵, or snow, you may have less tyre traction.

16
MAINTENANCE
Warning - the maintenance of electrical components requires special skills
and is not carried in 󰘵ores but in Decathlon regional workshops and can take
several days.
All cleaning work mu󰘵 be done with the battery on the bike but the bike
turned o󰘯! That way, the battery connections will be hidden and protected
from the water.
Electrical or mechanical maintenance operations mu󰘵 be carried out with
the bike switched o󰘯, with the battery removed from the bike. Maintenance
operations speci󰘰c to the bike’s electric sy󰘵em other than checking the
connections mu󰘵 be carried out by quali󰘰ed, trained personnel.
NB: the weight of the bicycle may exceed that of your assembly 󰘵and or
bicycle rack.
6 months
We advise you to bring your electrically-assi󰘵ed bike back to your DECATH-
LON 󰘵ore for its 6-month service.
Always carry out maintenance operations in su󰘲cient light.
If the bike or battery su󰘯ers a fall, check that your battery is intact.
If the battery is physically damaged, go to a DECATHLON workshop for a
battery diagno󰘵ic te󰘵.

17
Prohibited: cleaning using a high-pressure jet.
Not recommended: cleaning under running water.
Recommended: cleaning using a damp sponge.
In case of puncture to the rear wheel, remember to disconnect the motor
cable before removing the wheel from the bike to perform the repair.
If you turn the bike wheels upward (puncture repair etc), be sure to protect
your screen by swivelling it downwards to avoid damaging it.
The motorised wheel is also subject to higher 󰘵ress than a 󰘵andard bike
wheel, and although it is reinforced, it is possible that spokes may break. If a
spoke breaks, contact your DECATHLON 󰘵ore.
For more information on use, maintenance, after-sales services or in case of
que󰘵ions, visit DECATHLON’s support website: www.support.decathlon.fr/
or visit a DECATHLON 󰘵ore.

CONTENTS OF THE COMMERCIAL WARRANTY FOR YOUR ELECTRI-
CALLY-ASSISTED BIKE
Please ensure that you keep your invoice as proof of purchase.
The bicyle has a lifelong guarantee on the 󰘵ructural components (frame, handlebar 󰘵em, handlebar and saddle-pillar), 2 years on
parts subject to normal wear and tear.
The warranty does not cover damage resulting from misuse, from a failure to respect the precautions for use, from accidents, from
improper use or from commercial use of the bike.
This bike is for personal use only and not for professional use.
The warranty does not cover damage resulting from repairs carried out by persons not authorised by Decathlon.
Each electronic component is permanently sealed. Opening one of these components (battery, battery sheath, controller, screen,
motor) may cause physical injury to persons or damage to the sy󰘵em. Opening or modifying a component in the sy󰘵em will void the
warranty for the bike. The warranty does not cover cracked or broken screens showing visible signs of impacts.
FURTHER DETAILS REGARDING THE LIFETIME WARRANTY ON B’twin BIKES, purchased as of 1 June 2013.
B’twin brand bikes are products designed to provide complete satisfaction to their users. For this reason, B’twin wishes to commit
to the quality and durability of its bikes. Within this context, B’twin o󰘯ers its clients a lifetime warranty which exclusively covers the
following noncarbon parts: frames, rigid forks (non-suspension forks), handlebars and 󰘵ems 󰘰tted to B’twin brand bikes. This warranty
begins on the date of purchase of (a) B’twin brand bike(s).
It is speci󰘰ed that, for the lifetime warranty to be valid, the buyer mu󰘵:
either have a DECATHLON 󰘵ore loyalty card and regi󰘵er his/her purchase on it at the time of checkout,
or complete the warranty certi󰘰cate available online on the www.btwin.com site within one month of the purchase date. During this re-
gi󰘵ration, the buyer mu󰘵 provide the following information: la󰘵 name, 󰘰r󰘵 name, purchase date, e-mail address, and bicycle tracking
number.
By virtue of this warranty, B’twin o󰘯ers either the replacement by an equivalent of the frame, rigid fork, handlebars or 󰘵em, or their
repair, within a reasonable time period, after being brought to a DECATHLON retail 󰘵ore repair shop. It is speci󰘰ed that travel and
transportation co󰘵s remain the responsibility of the cu󰘵omer.
However, this contractual obligation will not apply in the event of poor maintenance or misuse of B’twin bikes, as de󰘰ned in the user
manual of the product in que󰘵ion.
To bene󰘰t from the warranty covering one of the parts li󰘵ed above, you mu󰘵 simply visit the repair shop of a DECATHLON retail 󰘵ore,
bringing either your DECATHLON 󰘵ore loyalty card or your warranty certi󰘰cate with you.
B’twin reserves the right to verify that all conditions of the lifetime warranty have been met and to implement all due necessary mea-
sures to verify this.
It is also speci󰘰ed that the lifetime warranty does not exclude the application of the legal guarantee(s) provided for under the French
Consumer Code (Code de la consommation) and Civil Code (Code civil), namely:
Article L. 211-4 of the Consumer Code: «The seller mu󰘵 deliver goods in conformity with the contract and take responsibility for any
lack of conformity present at the time of delivery. The seller is also held liable for any lack of conformity caused by the packaging, the
assembly in󰘵ructions or the in󰘵allation if he/she was made responsible for the latter under the contract or if it was conducted under
his/her responsibility».
Article L. 211-5 of the Consumer Code: «To be compliant with the contract, goods mu󰘵:
Be suitable for the use normally expected for similar goods and, if necessary:
match the description provided by the seller and possess the qualities that he/she presented to the buyer in the form of a sample or a
model;
display the qualities that a buyer can legitimately expect in view of public 󰘵atements made by the seller, the producer, or his/her repre-
sentative, notably in advertising or labelling;
Or display the features de󰘰ned by a mutual agreement between the parties or be suitable for any special use sought by the buyer,
made known to, and agreed upon by, the seller».
Article L. 211-12 of the Consumer Code: «Legal action prompted by lack of conformity lapses two years after the date of delivery of the
goods.»
Article 1641 of the Civil Code: «The seller is bound to the warranty on account of hidden defects of the item sold which render it un󰘰t
for the use for which it was intended, or which so impair that use that the buyer would not have acquired it, or would only have paid a
lesser price for it, had he/she been aware of them.
Article 1648 paragraph 1 of the Civil Code: «Legal action prompted by unacceptable defects mu󰘵 be brought by the buyer within a
period of two years from the date of discovery of the defect».
