E-Bikes with electric motors (electric bikes) are designed to be used on good
surfaces and roads, and they are not suitable for off-road terrain. The
maximum capacity of eBike is 120 kg including cyclist and bags.
Usage
When accelerated, the user must use his/her own muscle power. This is
essential when much energy is required.
If the battery is not charged, the safety protection is activated, and the
display will indicate that the battery needs charging. In this case, charge the
battery immediately.
Please notice the following must be in accordance with current laws and
regulations:
•The assist will automatically be deactivated at 25 km/h.
•If the motor does not initiate when the eBike is used, first check that the
battery is properly installed. If the problem persists, contact the store
where the eBike was purchased.

8
Purchase
Please note the following:
•Your bike is ready for use and has been controlled by a professional.
•The dealer informed you about the bike's functions and the safety
features.
•Always ask for the original instructions when dealing with complicated
parts.
Before using the eBike:
Read and implement the safety checklist.
Practice riding and braking on a safe surface, first using the rear brake and
then gradually using the front brake. You must be able to perform a complete
full stop without losing control. If the front tyre stops turning, the eBike will
become unstable and therefore the brakes should be adjusted by an expert.
After 4 weeks or 300 km.
•It is normal for any bike - even the most sturdy and expensive - to have
the brakes, gears, bearings and wheels adjusted regularly. This is done to
prevent product and personal injuries and malfunctions.
•Read these instructions carefully and make sure that the bike is properly
assembled before using it.
•Be careful when riding in the rain, on gravel or on slippery roads.
•The bike can be used in the rain without damaging it. However, the
electrical parts, such as the battery and the motor, should never be
immersed directly in water.
•Never touch the battery terminals with bare hands and never attempt to
short-circuit it.
•Never disassemble the electrical machine part. Contact a specialist.
•Never lend your eBike without prior thorough instruction in its use.
•Batteries are affected by different weather conditions. Generally, a
battery performs best when used at temperatures above 0 °C. The
battery capacity is reduced by approx. 1/3 at freezing temperatures.
Therefore, the driving distance will be reduced during use below 0 °C.
However, the battery is not damaged when used at temperatures below
0 °C.

Traffic laws and regulations
Traffic regulations and laws dictate the following:
Lights: Between sunset and sunrise, you must have and use one white light
pointing straight forward and one red one pointing straight back.
Reflectors: Your bike must have at least one red rear reflector and four
amber pedal reflectors.
Brakes: Your bike should have two functioning braking systems. Bikes in UK
generally have the right-hand lever for the front brake and left hand one – for
the rear brake.
Bell: Bike bells are not required by law in the UK, but it’s good to have it. A
polite but determined, chiefly British “Excuse me” can also work as a less
aggressive warning device.
Helmet: Wearing a helmet while riding is not mandatory.
Cycling rules in the UK
•Everyone must drive/ride on the left-hand side of the roadway. Never
ride your bike against the traffic flow.
•The use of cycle lanes is not compulsory and will depend on your
experience and skills, but they can make your journey safer.
•You may use a lane shared by bikes and pedestrians, but if it’s segregated
you must keep to the side intended for cyclists. In these cases, take care
when passing pedestrians, especially children, older or disabled people,
and allow them plenty of room.
•You cannot cycle on sidewalks / footpaths.
•In pedestrian areas, only ride your cycle if there aren’t too many
pedestrians about; otherwise dismount and push it. Also, if there is
signage specifically prohibiting cycling in such areas, you’d better respect
it.
•You can ride across cycle-only crossings and so-called Toucan crossings
– light-controlled crossings for both cyclists and pedestrians. They are
push-button operated. On any other type of crossing you must dismount
and walk across.
•You must not cross the stop line when the traffic lights are red. Just
don’t. Ever (yes, even when there’s nobody around). Some junctions

10
have an advanced stop line for cyclists where you can wait ahead of
other traffic.
•Do not pass between the curb and a bus when the bus is in a bus station.
•You must not carry a passenger unless your bike has been built or
adapted to carry one.
•You are not allowed to hold onto a moving vehicle or trailer.
•When approaching a junction on the left, watch out for vehicles turning
in front of you, out of or into the side road. Just before you turn, check
for undertaking cyclists or motorcyclists. Do not ride on the inside of
vehicles signaling or slowing down to turn left. Pay extra attention to
those nasty big trucks, they are dangerous to cycle next to, especially at
junctions.
•If you are turning right, check the traffic to ensure it is safe, then signal
and move to the center of the road. Wait until there is a safe gap in the
oncoming traffic and give a final look before completing the turn.
•Take extra care when crossing tramway tracks. You should also dismount
at level crossings where a ‘cyclist dismount’ sign is displayed.
•Cycling while drunk is, of course, a big NO. While there is no legal limit
for the alcohol volume accepted when riding a bike and nothing will
happen to your driver’s license, the police can decide you are not able to
ride safely and fine you by up to £2,500.
•We also recommend having liability insurance. Check with your insurance
company that your insurance covers all damages you may incur on the
bike.
•Cyclists must always respect all applicable traffic regulations and laws.

11
Safety checklist
Troubleshooting for this section can be found in the section
"Troubleshooting"
•Squeeze the brake levers using all your arm power - the handles should
not touch the handlebar.
•Squeeze the brake levers and pull the bike forward - the brake pads must
clamp tightly around the discs/rims.
•Brake front tire and turn the handlebar - the handlebars must not be able
to rotate.
•The saddle must not be able to rotate or rotate up or down.
•Check that the tyre is not blocked, the release lever/arm should not
protrude.
•Turn the tyres - they should be in line and move smoothly without
touching other parts of the bike.
•Let the bike fall freely from 20 cm height - if accessories such as rear bike
rack, displays or lights are moving or falling off, they may be mounted
incorrectly.
•Check the lights and the bell.
•Check tyre condition and pressure and look for loose spokes.
•Check the frame, handlebar and grip for scratches and dents.
•The brakes and cables should not show signs of wear or damage.
•Check for broken links in the bike chain.
•Test the brakes and gearshift with a test drive.
•Check the electric motor and the charging level.

12
Troubleshooting
Maintenance performed by unqualified technicians can result in serious
accidents:
•The brake lever screw can be used to adjust the distance between the
handles and the handlebar.
•Brake adjustments should be performed by an expert.
•Normally the handlebar can be tightened using a screw that is in the
center of the handlebar. All other adjustments should be made by an
expert.
•Tighten all screws around the saddle.
•The saddle and handlebar can only be adjusted up to the line on their
respective bar.
•Align the tyre, tighten the nuts and lock the release lever/arm.
•Loosen and straighten the tyre - the distance from the front fork and
frame should be proportional.
•Tighten loose screws. Have an expert repair any part or screw that is
defective.
•Tighten loose screws, replace the lights, secure the cables.
•Pump air into the hose with a hand pump - compressed air can damage
the tyres. Get an expert to repair defective tyres or loose spokes.
•Any minor damage should be repaired by qualified personnel.
•Damaged cables should be replaced by qualified personnel immediately.
•Damaged chains should be replaced by qualified personnel immediately.
•If the brake is too powerful, weak or unstable, or if the bike is running
unstable or irregular, or if the gearshift does not work optimally, the
eBike must be repaired by an expert.
•Consult a qualified service center for servicing the electric motor.

13
Safe bike ride
•Only use the bike if you are healthy and in good shape.
•Do not use the bike if you are affected by alcohol, drugs or medication.
•The bike should be adjusted according to your weight.
•Practice cycling, braking, shifting gears and turning safely before riding in
tight traffic.
•Wear gloves in cold weather to always be able to hold the handle with
both hands and use force when braking.
•Always keep your bags secured on the rear bike rack.
•Do not hang bags on the handlebar. Risk of serious accidents.
•Be aware of the effect of heavy bags: use proper bicycle bags that ensure
the bike's balance.
•Bicycles have a longer braking distance than cars, so be sure to respect
the safety distance.
•The braking distance increases on damp, wet or dirty surfaces.
•Ride with caution - electric bikes do not accelerate fast!
•Do not make any sudden movements while starting the bike, otherwise
you risk falling.
•Practice a quick start before a climb to avoid riding too slowly and thus
risking crashing the bike.
Transportation
•When transporting the bike, it must be fixed horizontally on a suitable
roof mounted bicycle rack on the car to avoid unnecessary strains on the
handlebar and other parts.
•Remove all accessories such as displays, bottles, pumps etc., otherwise
these can loosen during transport.
•When the bicycle is transported at high speed and in rain, water will
penetrate the bearings and into cables which cause damages.
•Make sure the rear derailleur/gear is upwards to avoid damage if the
eBike is transported horizontally in a vehicle.
•Read and perform the safety checklist before any kind of transport.

14
Maintenance
•Every bike should be checked by an expert at least once a year. This to
find eventual hidden defects such as micro-damage to the frame or
handlebars, broken brake cables, broken tyre rims, worn brake pads, etc.
•Use only suitable and original spare parts - pay attention to the
replacement of brake pads to fit the tyre rim and that the brake force
meets local traffic regulations.
•In case the control display shows an opaque error message, contact the
store where the eBike was purchased.
•Keep the bike and display clean and avoid water ingress (rain is not a
problem). Do not immerse the battery into water. Do not clean the bike
with a water pump or a pressure washer. Only use a damp cloth.
•Always keep the battery charged regardless of whether the bike is in use
or not.
•Use only the original battery charger.
•If the eBike is to be stored, be sure to recharge the battery regularly - at
least once a month - to prevent the battery from losing capacity.
•Store the battery in a dry place at room temperature.
•The battery reaches its maximum charging capacity after being charged
10 times.
•Do not expose the battery to high temperatures such as direct sunlight,
open flames, etc.
•If the battery leaks after an accident, it must be replaced immediately.
Contact the store where the eBike was bought.
•Batteries may not be disposed as general waste but must be disposed at
a waste disposal site according to applicable laws and regulations.
•Do not strain the bike. This includes using bicycle trailers and off-road
riding.
•Remember to assist the electrical energy using your own muscle power
at steep inclines to prevent the system from overheating. In case of
overheating, a fuse is activated to avoid personal and/or product
damages.
•To save battery power during acceleration, you can assist by using your
own muscle power.

15
Cleaning and storage
Cleaning
•Regularly clean your bike - this is also the best way to find eventual
damages on the bike.
•Bicycles should not be cleaned with a pressure washer, with steam or
water jets. These cleaning methods can push sand grains and moisture
into the bearings and cables, thereby damaging the bicycle.
•Clean the bike with warm water and soap to remove grease and dirt. You
can find a suitable cleaning product at your local bicycle dealer.
•Also clean the chain and gears. A clean and greased chain that runs
smoothly increases the life of the gears.
•After cleaning the chain and gears, lubricate them by using a suitable
water-repellent product.
•Problems such as dirty or rusty parts, especially when it comes to the
chain, are not included in the warranty. Chains are not immune to rust
and should be cared for.
•Remove residual grease from the tire rim after cleaning and lubrication.
•Remaining grease on the tire rim can reduce braking efficiency.
Storage
•When not in use, store the eBike in a dry place. If it is outside, its life can
be reduced. Therefore, it is also important to protect the bike with an
anti-rust coating. This product can be purchased at your local bicycle
dealer.
•If the bike is not in use for a long period of time, it can be hung on the
wall as it will protect the tyres from damage.
•Clean and prepare the bike before storing and have it checked by a
specialized bicycle mechanic.
•Remember to deactivate the system by turning off the main switch.
•Even though the bicycle can be used in rain and poor weather, the bicycle
must be stored under a roof preventing moisture from affecting the
electrical parts and the motor.
•Remember to protect the bike against theft.
•Remember to charge the battery every month, when the eBike is
stored.
