3. Statutory warranty and warranty claims
Explanation of the statutory warranty
The manufacturer grants a 24-month warranty (“liability for defects”) on new goods (§ 439 and 476
German Civil Code (BGB)).
The warranty covers defects already inherent in the product at the time of purchase. If you discover
a defect, you can demand that the manufacturer repair or otherwise rectify the product.
If the seller is of the opinion that the defect only arose after the purchase, he must prove this during
the first six months. After six months, however, the burden of proof is reversed. Then the buyer has
to prove that the defect already existed at the time of purchase.
Explanation of guarantee
The guarantee is granted on a voluntary basis by the manufacturer (manufacturer's guarantee). The
duration and conditions of the guarantee can be freely determined by the manufacturer.
Manufacturer's guarantee
The manufacturer grants a guarantee of 2 years on frame breakage and 6 months on the entire bike
and its attachments. This guarantee does not cover parts subject to wear, e.g. chains, pedals,
toothed belts, tyres, wheel rims, inner tubes, bearings, gear shift mechanism, brake pads, chain
sprockets, pinions, bottom bracket, gear shift and brake cables as well as paintwork and stickers. The
warranty does not cover damage caused by failure to observe the assembly instructions or by im-
proper use (jumps, stunts, tricks, wheelies, downhill). The bike is intended exclusively for private use.
Damage caused by rental, leasing or participation in competitions is fully excluded from the war-
ranty. Repairs, conversions or other modifications to this bike carried out independently and without
consulting the manufacturer will void the warranty. The warranty will also be voided if the mainte-
nance intervals prescribed in this manual are not observed and a thorough inspection of your bike is
not carried out at least once or twice a year.
The original proof of purchase must be kept together with the service booklet in order to substanti-
ate warranty claims. With the purchase, the guarantee terms are accepted in full and without qualifi-
cation.
The following conditions apply:
-No guarantee in the case of accident damage
-No guarantee in the case of improper use
-No guarantee in the case of use for purposes other than the intended use
-No guarantee in the case of damage resulting from improper assembly

Consequences of warranty claims
If a warranty claim occurs within 14 days, the customer has the right to return the product free of
charge for a full refund of the purchase price. Optionally, the customer is entitled to a remedy of the
defect in the form of a repair or a replacement of the defective component.
After the expiry of these 14 days but still within the first 6 months from the date of purchase, the
customer is entitled to a remedy of the defect in the form of a repair or a replacement of the defec-
tive component.
Service and preventive maintenance
Please note that you are only entitled to the manufacturer's warranty if you
observe the service intervals and have the preventive maintenance carried
out.
The customer is responsible for observing the service intervals and having the preventive mainte-
nance carried out (see 21 Unpacking and assembly on p. 7).
Any service and maintenance work must be carried out by a suitably qualified person. Please have all
service and maintenance work documented with signature in your service booklet that you will find

4. Theft prevention
I M P O R T A N T
The frame number is not filed by us together with the
buyer’s purchase order.
Record the frame number in your bike passport or on
your invoice and register your bike with the police free of
charge!
-Use a suitable bike lock to protect your bike from theft.
-If possible, park your bike only in designated areas, preferably in heavily frequented areas.
-Register your bike with the frame number free of charge with the police. For this, fill in your
bike passport that you will find on p. 73 of this operating manual.
-As a precaution, check whether your household insurance covers the theft of pedelecs, and
what the conditions for this are..
5. Performance tuning forbidden
F O R B I D D E N
Modifications and/or performance tuning are strictly
prohibited!
In the event of an accident/damage (without insurance
cover), the rider is liable with his entire private assets!
Performance optimisation (tuning) of EPACs is illegal. According to the German Road Traffic Licensing
Regulations (StVZO), an EPAC whose motor accelerates the bike to more than the permitted 25 km/h
is considered a motor vehicle. This requires an insurance number plate, an operating permit (ABE)
and a corresponding driving licence (driving licence class AM or class B).
The EPACs sold by the manufacturer do not have an operating permit as is the case, for example,
with S-pedelecs. Performance optimisation thus has the following consequences for you:
-Tuning is considered a significant modification of the EPAC.
-The manufacturer's declaration of conformity is voided.
-No warranty or defect liability claims can be made.
-Riding without an operating permit can result in a fine.
6. Recommendation for insurance cover
The manufacturer recommends taking out private liability insurance for riding an EPAC!

7. Safety
Intended use
N O T E
The intended use also implies reading and understanding the operat-
ing manual!
Bicycles are used to transport a single person. Because the necessary safety equipment according to
StVZO is not included in the scope of delivery, your bike is not intended for use on public roads.
Simple forest and dirt roads can be driven with the technical equipment without further ado. Your
bike is not intended for:
-Jumps
-Wheelies
-Stunts
-Downhill
-Riding down steps
-Riding through deep water
-Participation in sporting events
The intended use also implies observing the recommended maintenance intervals and reading and
understanding this manual.
Unauthorised modifications forbidden
F O R B I D D E N
Modifications (like mounting a child seat, carrier or a bicycle trailer)
are permitted only with the consent of the manufacturer! Modifica-
tions not approved by the manufacturer will void the declaration of
conformity.
Unauthorised modifications or changes to the bike can result in serious injuries and voiding of the
guarantee. This applies in particular to manipulating and modifying the electric motor and control
unit.
Never modify the control unit or the electric motor.

Attachment of luggage racks and/or trailers
The attachment of other of further luggage racks and/or trailer couplings is only permitted by agree-
ment with the manufacturer.
Unauthorised modifications or attachments of load carriers of any kind without the consent of the
manufacturer will void the declaration of conformity supplied and the entire risk must be borne by
the user.
Minimum age
From a legal point of view, there is no minimum age for the use of an EPAC. We recommend, how-
ever, that it should be used only by persons over the age of 14.
Personal qualifications
This manual is intended for instructed riders. The rider should have the following know-how and ex-
perience:
-The rider has been instructed in the use of the bike by a dealer
-The rider knows that improper use of the bike can result in accidents
-The rider can use the bike in accordance with this manual
Personal protective equipment

Basic safety instructions
Permissible total payload
Your bike is for a total payload of 120kg designed. The total pay-
load includes the empty weight of the bike including the battery
(this is 22.7kg), the driver and additional luggage. Do not exceed
the total permissible payload. This can lead to damage to me-
chanical components such as the frame or suspension fork and
represents a considerable security risk!
Stability (kick stand)
The kick stand on your bike is only designed for the empty weight including the battery.
Never sit on your bike with the kick stand down. In the worst case, this could lead to a break in the
side stand and serious injuries from the bike falling over!
Wear a helmet
We recommend that you always wear a suitable bicycle helmet when riding. The right fit and the
right size of helmet is crucial!
Avoid serious injuries or death due to mechanical defects and improper use of the bike
Riding a bike can result in serious injury or death due to a mechanical defect or improper use of the
bike.
-Always carry out a safety check (see section Riding your bike) before riding your bike.
-Familiarise yourself with the brakes, pedals and gears before riding.
-Always ride at a speed appropriate to the riding conditions.

Avoid electric shocks or explosions due to improper handling of the battery and charger.
F O R B I D D E N
Never open the electric motor,
battery and other components!
Improper handling of the battery and charger can result in an electric shock or explosion. This may
cause serious injury or even death.
-Use only the battery included in the scope of supply.
-Never connect the positive terminal to the negative terminal of the battery.
-Protect the battery from direct sunlight.
-Do not dismantle the battery.
-Use only the charger included in the scope of supply to charge the battery.
-Use the charger only indoors.
-The plug of the charger is the disconnection device from the electrical mains. Ensure that the
plug socket is located near the charger and is easily accessible.
-Connect the charger only to a grounded 230 V mains plug socket.
-Keep the metal contacts clean; clean them with a soft and dry cloth, if necessary.
-Do not charge a battery with visible damage, e.g. a broken battery casing.
-Do not use a battery with visible damage, e.g. a broken battery casing.
-Do not drop the battery.
-Charge the battery in a temperature range between 10° and 30°C.
-Ensure that the charger is used only by persons who do not have limited physical, sensory or
mental abilities.
Avoid fire or explosion hazards
F O R B I D D E N
Cleaning your bike and its components
Never clean your bike with a water hose, high-pressure or
steam cleaner!
Moisture, electrically conductive soiling or mechanical damage can cause a short circuit. This could
lead to a fire or explosion of the battery.
-Clean the electric motor and the controller only from the outside with a damp sponge. Never
use a high-pressure cleaner.
-If these components are accidentally completely immersed in water, disconnect the motor
from the battery immediately and do not use it again until it has been inspected by the man-
ufacturer.

25.08.2021 REV 1.1
17
Avoid serious injuries due to contact of body parts with the components of the bike
C A U T I O N
Risk of injury from reaching into the
drive chain.
Never reach into the drive chain while riding.
When riding, parts of the body or other objects may come into contact with the sharp teeth of the
sprockets, the moving chain, the rotating pedals and cranks and the rotating wheels of the bike. This
can lead to serious injuries.
-Take care when riding that parts of your body do not come into contact with these compo-
nents of the bike.
Avoid serious injuries caused by damaged components
When riding off-road or over kerbs, the electric motor, cranks or bottom bracket may touch the
ground and be damaged. This can lead to serious injuries.
-Use the bike only on the approved surfaces.
-If you encounter obstacles, dismount and lift the bike over the obstacle.
-In the event of damage, have the bike inspected by a dealer.
Avoid serious injuries or death in wet weather
C A U T I O N
Wet and/or slippery roads and paths influence the road grip and
braking behaviour!
Wet weather affects road grip, braking behaviour and visibility for both cyclists and all other road us-
ers. In wet weather, the stopping power of your brakes (as well as the brakes of all other road users)
is significantly reduced. In addition, the tread pattern does not grip nearly as well as on dry roads.
This makes speed control more difficult and increases the risk of losing control over the bike. This
may cause serious injuries or even death.
-Always ride slowly in wet weather.
-Always brake carefully and with foresight in wet weather.
-Switch off the electric motor or ride carefully with minimum motor assistance.

Operating Manual –Mountain bike with electric motor / 250 W rated power
05.08.2021 REV 1.1
18
Avoid serious injuries or death in twilight or at night
N O T E
We generally recommend riding with your lights on even during
the day.
Riding with lights is crucial
in twilight or at night!
Riding in twilight or at night is more dangerous than during the day. A cyclist is very difficult to recog-
nise for other road users and this can result in serious injuries or even death.
-Avoid riding in twilight or at night, if possible.
-Always ride slowly.
-Always ride with bike lights and reflectors.
-Always avoid dark areas and areas with heavy or fast traffic.
-Always avoid road obstacles.
-Ride on familiar routes, if possible.
Avoid serious injuries or death caused by damaged, bent or loose reflectors and lights
Bike reflectors catch the light from street lamps and car headlights and reflect it so that you can be
recognised as a cyclist. Damaged, bent or loose reflectors can result in you being poorly recognised
