General Settings
GETTING STARTED
1. The display pad is equipped with 3 buttons including “M”, “UP” and “DOWN”. The M button is the mode/switch button.
2. Press and hold the “M” button on the handlebar controls to turn on the display. Now, your ebike is ready to ride. To turn off, press and hold
“M” for 3 seconds.
3. Press the “M” button on the handlebar controls to switch the contents of the multi-functional display area.
4. Press and hold the “UP” button on the handlebar controls to turn on/off the light.
5. The Level ebike offers pedal assist. When using pedal assist, an electric motor supplements the rider’s own effort. To use the pedal
assist, simply start pedaling, then tap the “UP” or “DOWN” arrows to increase or decrease the amount of pedal assist.

Driving Range
The range of your KBO Bike is the distance the bike will travel on a single full charge of the onboard battery pack. The range values in this
manual are estimates based on expected usage characteristics. Some of the factors which affect the range include changes in elevation, speed,
payload, and acceleration, number of starts and stops and ambient air temperatures. Tire pressure and terrain are also important variables to
consider.
We suggest that you select a lower pedal assist level when you �irst get your KBO Bike to get to know your bike and travel routes. Once you
become familiar with the range requirements of your travel routes, and the capabilities of your KBO Bike you can then adjust your riding
characteristics if you desire.
The following table provides general estimates and outlines various factors’ effective range and their combined estimated effects on range. This
table is meant to help owners understand the factors that can increase or decrease range, but KBO Bike makes no claims to the range that
individual users might obtain.
Best Practices for Extending Range and Battery Life
◆Do not climb hills steeper than 15% in grade.
◆Pedal to assist the motor when climbing hills and accelerating from a stop.
◆Avoid sudden starts and stops.
◆Accelerate slowly.
12

Parking Storage and Transport
Please follow these basic parking, storage and transport tips to ensure your bike is well cared for on and off the road.
◆ When pushing the vehicle manually, turn off the power to avoid accidental acceleration from the motor.
◆ It is recommended to park indoors.
◆ Switch the power off, and any lights to conserve battery. Remove the key from the bike and ensure the battery is locked to the frame or
removed and brought with you for security.
◆ In public places, your KBO Bike must be parked in accordance with local rules and regulations.
◆ If you must park outdoors in rain, or wet conditions you should only leave your KBO Bike outside for a few hours and proceed to park the
bike in a dry location afterwards to allow all the systems to dry out. Much like a regular bike, use in wet conditions mandates a more regular
maintenance schedule to ensure your bike does not become rusty, corroded and to ensure all systems are always working safely.
◆ Do not park, store, or transport your KBO Bike on a rack that is not designed for the size and weight of the bike.
◆ Locking up your bike is recommended to ensure your bike is secure and the chance of theft is reduced. KBO Bike makes no claims or
recommendations on the proper lock hardware or procedures to secure your bike, but we do recommend you take the appropriate
precautions to keep your KBO Bike safe from theft.
◆ When storing your bike or carrying your bike on a rack for transport, you can remove the battery pack to reduce the weight of the bike
and make lifting and loading easier.
13

Basic Battery Charging Tips
◆ The battery should be recharged after each use. There is no memory effect, so you can charge the battery after short rides without damage.
◆ The battery can be recharged on or off the bike.
◆ Remove the battery by turning the key and then pulling the battery forward and up until the battery detaches from the mating receptacle.
◆ The charger will automatically stop charging when the battery pack is full.
◆ Always charge in dry locations and indoors away from direct sunlight, dirt or debris.
◆ Do not cover up the charger when plugged in or charging, it air cools and needs to be left in an open space. Do not charge with the charger
in the inverted position which can inhibit cooling and reduce the charger’s life.
◆ Check the charger cables, charger and battery for damage before beginning each charge.
◆ The light on the charger will turn green when charging is complete and stay red while the battery charges. Ensure the light faces upward
when charging
Charging Time
When the input and output plugs of the charger are connected properly, and the battery is not fully charged, the red charging indicator light
should illuminate, showing that the battery is charging. The time that the battery takes to fully charge the battery is dependent on various
factors including distance traveled, riding characteristics, terrain, payload, and battery age.
NOTICE: The battery pack can take longer to charge when fully depleted and when the battery is new. As your battery ages you
might also experience increased charging times, but this is only expected after 3-5 years of regular use. If your battery does not
seem to be charging normally, and taking longer to charge than expected, please discontinue charging and contact KBO Bike
immediately.

Bicycle Care
To ensure safe riding conditions you must ensure your bike is properly maintained. You should follow these basic guidelines and see your
certi�ied bicycle mechanic at regular intervals to ensure your bike is safe for use.
1. Properly maintain batteries by keeping them fully charged when not in use.
2. Never immerse the bike or any components in water as the electrical system may be damaged.
3. Periodically check wiring and connectors to ensure there is no damage and the connectors are secure.
4. To clean, wipe the frame with a damp cloth soaked in a mild non-corrosive detergent mixture. Dry with a cloth.
5. Store under shelter; avoid leaving it in the rain or exposed to corrosive materials. If exposed to rain, dry your bicycle afterwards and apply
anti-rust treatment to chain and other unpainted steel surfaces.
6. Riding on the beach or in coastal areas exposes your bicycle to salt which is very corrosive. Wash your bicycle frequently and wipe or spray all
unpainted parts with anti-rust treatment. Damage from corrosion is not covered under warranty so special care should be given to extend the
life of your bike when used in coastal areas or areas with salty air or water.
7. If the hub and bottom bracket bearings have been submerged in water, they should be taken out and re-greased. This will prevent accelerated
bearing deterioration.
8. If the paint has become scratched or chipped in the metal, use touch up paint to prevent rust. Clear nail polish can also be used as a preventa
tive measure.
9. Regularly clean and lubricate all moving parts, tighten components and adjust as required.
