Both contain important safety,technical, and performance information, which should be read before your rst ride. Please retain this
information for future reference. The Owner’s Manual should also be read because it has additional important information relating to the
bicycle, bicycle maintenence and rider safety.

INTENDED USE
The KHS Extended 2.0 DE is intended for General Purpose Riding use only. The Extetended 2.0 DE is classied as a Pedelec/EPAC. It
will provide motor support while pedaling. When you stop pedaling, the motor wil stop providing assistance.
RIDING TIPS
Here are some tips to increase the battery range and reduce excess wear on the bicycle and components.
• Pay attention when approaching a turn. Be sure to stop pedaling before turning and keep the crank/pedal on the side of the turn at
the top of the stoke to prevent the pedal from hitting the ground while turning.
• Learn to ride eciently and keep your eyes on the road ahead. Excessive use of the brakes drains the battery quicker than
necessary. More energy is needed to recover the speed.
• Shift gears regularly to stay in an optimal cadence range and downshift before coming to a stop.
• Reduce pedal force before initiating a a gear shift to reduce drivetrain wear.
• Check the tire pressure regularly. Lower tire pressure can cause extra drag on the tires.
• If the bicycle is exposed to cooler weather, keep the battery stored indoors until you begin to ride.
• Do not exposed your bicycle and batttery to prolonged excessive heat or direct sunlight.

GENERAL MAINTENANCE
For information about general maintenance please refer to the KHS Bicycles Owner’s Manual.
• Great care should be taken not to damage the bicycle frame and bicycle components.
• When riding listen for any creaks. A creak can be a sign of a problem with one or more components or frame/fork. If you continue to
hear creaks, please arrange to bring your bicycle to your KHS Authorized Dealer for repair or inspection. If they notice anything out
of the ordinary, they will contact KHS directly to discuss.
• Exposure to harsh elements, especially salty air (such as riding near the ocean or in the winter), can result in galvanic corrosion of
components such as the crank and spindle and bolts, which can increase wear and shorten bicycle lifespan.
• Lifespan and the type and frequency of maintenance depends on many factors, such and use, rider weight, riding conditions
and/or impacts. Components may be subject to increased wear at dierent rates, depending on the component. Drivetrain and
brake components are especially subject to wear. Periodically have your your Authorized KHS Dealer inspect your bicycle and
components.
• Regularly lubricate the chain, drivetrain, and cables.
• DO NOT USE High-Pressure water spray on the bearings, gears, and chain. Even water from a garden hose can penetrate bearing
seals and crank interfaces, increasing bearing and crank wear. Use a clean, damp cloth and bicycle cleaning agents for cleaning.
• DO NOT expose the bicycle to prolonged direct sunlight or excessive heat, such as inside a car parked in the sun or near a heat
source such as a radiator.

BATTERY AND CHARGER INFORMATION
Your bicycle is powered by a Lithium-Ion (Li-Ion) battery.
• Only operate the battery between the temperature range of -20 degree Celsius (-4F) and +70 degree Celsius (+158F).
• Only use the supplied battery and battery charger sold with this bicycle, even if another ts.
• Always turn the battery o before connecting or disconnecting the charger to the battery.
• Turn o the battery, unplug the charger from the battery and remove the battery from the bicycle before performing work of any kind,
such as installation, maintenance, cleaning and/or repair. When transporting or handling the battery separately from the bicycle,
ensure the battery of OFF. Touching the contacts when the battery in ON can result in electric shock and/or injury.
