3. SETTINGS
THE SADDLE
The height of the saddle can be adjusted. Ease up on the quick release and set the desired height, without break-
ing the maximum height indicated on the seat post, and tighten the lock. You can also change the angle of the seat
so you are sitting comfortably. Untighten the screw under the saddle and set the appropriate angle. Then tighten
again properly before riding.
PEDALS
You can fold the pedals. Press the pedal a little inward and then fold it.
THE HANDLEBAR
The handlebar height is adjustable so you can have a comfortable ride. Open the quick release for the handlebar and adjust
to the proper height and then tighten it properly. Do not raise the handlebars higher than the maximum level indicated on the
stem. Always check that the handlebar is attached properly before riding.
THE FRAME
To fold the frame you first release the main quick release. Then li the open quick release upwards so the safety pin releases
from the frame and then fold the frame.

FOLD YOUR KRINGLA
1. Fold the pedals.
2. Fold-down the handlebar.
3. Fold up the frame.
4. Lower the saddle as much as possible.

BREAKS
Your Kringla has V-brakes, also called a rim brake. They brake eectively with pressure on the wheel rim. The brake pads wear
out over time and when they see worn out or are not working eectively they must be replaced.
ADJUST BRAKES AND BRAKE PADS
If you need to adjust the brakes it is easiest to start with the adjustment screw ( “A” on the picture) allowing the brake pads at
the wheel to move closer to the rim. Turn the screw outward from the handle until you feel the brake takes enough. A great
distance for brake pads from the rim to the wheel is 1.5-2 mm.

If the brake pads need to be adjusted more you do it by tightening or loosening the Phillips screws ( “C” on the picture) on the
side of the brake levers until the brake shoes are centered on the rim. By tightening the screw, the spring will be compressed
and the brake pad is moved away from the rim.
The brake pads can also be adjusted in height ( “D” in the illustration).
Aer a while, the brake cable might be stretched. Then you have to tighten the whole brake cable. This is done by loosening
the screw ( “B” in the picture), pulling on the cable so the tension increases and then tightening the screw again.
If you feel that you are not able to adjust the brakes yourself when your Kringla arrives to you aer purchase, you can take
help from a professional bicycle dealer or bicycle repairman to adjust your brakes. If they charge you we will reimburse you
for it.
GEARS
Sometimes the gears need to be adjusted aer delivery to you. Do not ride at high speed without checking that the gears work
smoothly. Try to change gears without sitting on the bike. Li the rear wheel and set the bike upside down, and let the rear
wheels roll freely and move the pedals by hand.
There are two screws (“E” in the picture below) on the derailleur arm at the rear wheel, where you can adjust the gears.
Tighten the le screw if the chain goes too far out on the lowest gear (gear 1). Tighten the right screw if the chain goes too far
out on the highest gear (gear 7).
If you find it diicult, you can go to your local bike shop for help. If they charge you we will reimburse you for that.

4. MAINTENANCE AND SERVICE
With regular maintenance, your Kringla works better and lasts longer. Maintenance consists of cleaning, lubrication and rou-
tine control of settings.
Regular maintenance is also a prerequisite for the guarantee to apply.
CLEANING
Use a sponge and a cloth and use soap designed for bicycles and bicycle oil for lubrication. Avoid very high pressure when
flushing away dirt.
Note that the bike needs extra care and cleaning in certain environments, such as salt (road salt, and near the coast), humid
and cold environments.
OIL AND LUBRICATION
This is an indication, but how much maintenance your Kringla needs obviously depends on how much you use it. Use oil for
bicycles.
WEEKLY
Chain, derailleur arm: Use chain oil. Rub or spray.
Gears, calipers, Brake Controls: Use oil. 2-3 drops from an oil can.
MONTHLY
Shiers: Dismantle. Use lithium-based fat.
EVERY SIX MONTHS
Cassette: 2 sprays of oil from an oil can
Brake cables: Disassemble and use lithium-based grease.
ANNUALLY
Bottom bracket, pedals, gear cables, Bearings, Headset, Saddle Post: Disassemble and use lithium-based grease.

CHAIN
A good rule of thumb is to lubricate the chain when you can touch it without getting grease on your fingers. The chain should
be lubricated regularly (particularly aer rain) with bicycle oil for the chain.
By manually stretching the chain, you can check that the chain tension is suitable. NOTE! Do not tighten the chain if you think
it is diicult. Instead, take help from your nearest bicycle dealer.
Try to pull the chain up and down. The maximum distance between the top to the bottom should be about 10-15 mm. If it is
not, you can proceed as follows:
1. Loosen the axle nuts on both sides of the rear wheel and the brake lever located on the le side of the frame.
2. Adjust the chain tension by tightening the clamping screws on both the le and right sides.
3. Check that the wheel is centered before you tighten the screws. Adjust if necessary.
4. Tighten the shoulder screws and tighten the screws really firmly.
5. Check the chain tension again.
A too loose or tight chain may cause the chain to jump when you ride or cause wear on the bike.
SERVICE
We recommend regular servicing. Follow the manual for the respective parts. If you can not do this on your own so you should
take your bike to your nearest bicycle shop or bicycle dealer.
STORAGE
Keep your Kringla dry and indoors as much as possible. It gives the bike a long and happy life.
5. THE BATTERY, ELECTRICITY, AND CHARGING
BATTERY SAFETY PRECAUTIONS
The handling of the battery is important for your safety and for the life of the battery. It is important to follow safety rules, as
improper use can lead to fire or other damages. We do not take responsibility for events that are caused by improper use.
• Always keep the electricity turned o when you are not sitting on the bike. Motor power starts when the pedals move.
Just a small movement of the pedals can start the motor and make the bike go forward.
• Plugs and contacts on battery and phone cord should be dry when charging.
• Do not use the battery near flammable materials or in poorly ventilated areas. The room temperature should not exceed
40 degrees C.
• Keep the battery away from water to avoid short circuits.
• Use only the original charger when you charge your battery.
• Do not disassemble or modify the battery.
• Do not expose the battery to shock.
• Remove the charger cord from the wall outlet first, and then plug in the battery. The charger should not be le in the wall
when you do not charge your battery.
• If something abnormal happens, such as overheating, or odor, stop charging immediately and contact us at Kringla, or a
professional.
• Charge and store your battery out of reach of children.
• Do not charge the battery in direct sunlight.

REMOVING AND ATTACHING THE BATTERY
To remove the battery, turn the key counterclockwise and press the key while inward. You also need to fold up the saddle. You
do this with the small spring in the back just under the saddle. Then you hold the handle of the battery and pull the battery
upwards.
You attach the battery by folding up the saddle holding the battery handle and then let the battery slip into its rails. Then,
when the battery is in place, turn the key clockwise back so the battery locks. Watch the video below at the time of 1:13.
HOW TO CHARGE THE BATTERY
• Make sure that your outlet works for your charger and is between 100V-240V.
• Turn o the power by turning the key counterclockwise, battery and display lights will go out. The bike should be turned
o when charging.
• The battery can be charged when attached to the bicycle or when removed.
• Plug the charger cable into the battery and insert the cord’s other end into your wall outlet. Watch the video below at
the time of 1:02. When you start charging the red light on the charger should light up. It is finished when the light on the
charger turns green.
• A full charge takes about 4-6 hours and it gives your Kringla a range of about 40-50 km, depending on how you ride.

TURNING ON THE BATTERY AND ELECTRICITY
The battery is started by turning the key clockwise. Then check so that the electrical indicator (small
green lights) on top of the battery is lit. There you can see the amount of electricity remaining in the bat-
tery. Refer also to the display on the handlebars.

TIPS AND RANGE
Your bike’s capacity and range will vary depending on battery condition, temperature, terrain, wind, tire pressure, the weight
of the rider, etc. You get the best performance if you avoid jerky driving and use your legs as much as possible.
Some factors that aect the range negatively:
• Yhe low temperature outdoors while riding.
• Headwind.
• Hilly terrain.
• So ground.
• Uneven speed (acceleration and deceleration).
• Low tire pressure.
• High speed.
• No or poor maintenance.
• Not using your legs enough.
• Heavy rider weight or heavily loaded.
• Battery condition and age have an influence on the range.
MAINTENANCE OF BATTERY
• Charge the battery immediately aer it is completely or almost completely empty. The battery will get damaged by being
le with zero charges for longer periods of time.
• Battery should be kept indoors at normal room temperature.
• If you do not use the battery for a while, it is best to have it charged between 60-70% of its capacity. Charge the battery at
least once every four weeks up to a capacity of 60-70%. This is equivalent to 2 out of 3 light on the battery.
• Storing the battery when it is not used for a longer period of time is best in temperatures between 5-15 degrees C.
• Do not use the battery on your bike if it is colder than minus 10 degrees C outside.
• Always take the battery indoors if it is below zero degrees C outside.
DISPLAY
You can choose from three dierent motor speed assists. LOW, MED and HIGH. There is a small light that shines on every level.
If you press the + button you increase the speed level and vice versa with the - button. If you press the - button until none of
the lights are lit you get no help at all from the motor and ride only using your legs.
If you hold down the 6 km/h button the bike starts moving by itself without you using your legs. This can be convenient when
starting from rest, such as when you are standing at a traic light and will start quickly and easily.
The brakes act as a “cut-o switch” for electricity so when you push them down, there will be no motor power.
