STEP 1
Open box. Be careful to not to damage you the bike or hurt yourself with any
sharp tool. Locate and remove smaller box containing the charger. The bike will
be mostly assembled inside the bike box with the front wheel and handlebars
strapped to the frame of the bike. Li the bike out of the box with another
person's assistance. Carefully remove the zip ties and foam from the bike. Set
the front wheel to the side. Damage occurring from unboxing or assembling is
not covered in the warranty. Please have a professional assemble the bike.
Unbox the charger and baery. Plug the charger into any standard wall
socket, then plug the other end of the charger into the baery port, which has a
rubber plug that can be apped open next to the power switch. The light on the
charger will turn red when plugged in and not completely charged. Charge the
baery until the light turns green before taking your rst ride. Indicator lights on
the side of the baery display general charge when baery is removed from the
bike. Baery charge indicator lights on the side of the baery will only work
when the power switch is on. A red blinking light indicates an error.
STEP 2
Warning: This bike must be assembled by a professional for proper
and safe function. Improper unpacking and assembly can cause damage to the
bike and/or bodily harm and is not covered by the ZOOZ Bikes warranty.

STEP 3
Hold the bike steady in an upright position on a so oor surface to avoid
scratching the frame or fork. Unscrew the 4 bolts from the top of the handlebar
stem and remove the stem clamp. Position the handlebars with the knurling
centered inside the handlebar clamp. Make sure that the control cables are not
tangled, twisted, or kinked. Position the handlebars at an upright angle with a
slight rearward or forward angle as per your preference. Tighten the handlebar
clamp so the gaps of the clamp in the front and the rear of the clamp are equal.
Give a gentle tighten on the handlebar clamp bolts for now. We will return to
these bolts during adjustment and torquing.
STEP 4
Remove the plastic brake caliper spacer and axle brace. Be sure not to squeeze
the brake while the clip or the wheel is removed. If you have accidentally done
this, use the brake caliper clip to gently spread the brake pads inside the brake
caliper. Prepare the front wheel axle for mounting by removing the front axle
nuts, at washers and hook washers.

pg. 5
STEP 5
Each pedal screws into the crank arms with threads that spin in the opposite
direction. Identify the pedals for each side by nding an R and L stamped on the
threaded spindle of the pedals. Thread them onto the crank arms by hand.
Rotating the pedals toward the front of the bike will tighten the pedals. Once
threaded, tighten with a 15mm open-end wrench to tighten snugly. We will return
to the pedals during adjustment and torquing.
Li the bike from the handlebars to lower the forks onto the front axle and
guide the disc into the brake caliper and the axle slots into the axle plates.
This is easiest to do with the help of another person. Slide on the hook washers
so that the hook is seated in the small hole on the axle plate. Slide the at
washer on next, then thread the axle nut on by hand and give a gentle tighten
with a 15mm closed-end wrench. We will return to these bolts during
adjustment and torquing.
STEP 6

pg. 6
Stop
The bike is now assembled, but you will need proper
adjustment and systematic checks regularly,
especially if the bike is geing heavy use. You
should routinely perform the following checks in the
following ‘Adjustment & Torquing’ section of this
manual. Checking all bolts before each ride is highly
recommended.
At times, it will be necessary to remove the baery; for cleaning, replacement or
charging in small spaces. To do so, insert and turn the key 180 degrees into the
“unlock” position. Grasp the baery in the middle and tug forward to slide it o.
When placing the baery back on the bike, reverse the process, placing the
baery at the front of the mounting plate and ensuring the tongue-and-groove
is fully engaged, and slide it back. Give it a good tug rearwards to make sure
it’s fully seated. Insert and turn the key back to the locked position to secure it.
It should be eortless to turn the key. If it’s not turning easily, it means the
baery is not properly seated. Remove it and try again.
STEP 7

Adjustment & Torquing
pg. 7
REAR WHEEL ALIGNMENT, CHAIN ADJUSTMENT
Rear wheel alignment and chain tension should be checked oen. Electric bikes sustain higher speeds and forces than standard bikes. Movable/adjustable parts can
move more frequently than regular bikes. Make sure that the rear wheel is properly aligned by equalizing the spaces between the rear wheel/tire and the frame on either
side using the adjusters. You must also make sure that there is chain tension for proper function. To do this, slightly loosen each axle nut on the rear axle and the lockout
nut on the adjusters until the axle slides freely in the axle slot. Align rear wheel while maintaining chain tension by tightening the adjuster bolts incrementally on each
side. Aer the axle is in the right position, tighten the adjuster lock nuts then tighten axle nuts to 350 in/lbs. The rear tire should be pressurized to t rider weight and
terrain. Lower pressures help smooth out rough terrain and provide more traction on some surfaces. 30-35 PSI for normal road terrain and rider 120-180 lbs. Add more PSI
up to the maximum recommended pressure labeled on the side of the tire for heavier riders as needed.

pg. 8
FRONT WHEEL ALIGNMENT
The front wheel should not ever come loose under proper assembly and
torquing. However, you should be sure that the axle is completely seled in the
axle slots, hook washers are in place and the axle nuts are torqued to 250
in/lbs. The front tire should be pressurized to t rider weight and terrain. Lower
pressures help smooth out rough terrain and provide more traction on some
surfaces. 30-35 PSI for normal road terrain and rider 120-180 lbs. Add more PSI
up to the maximum recommended pressure labeled on the side of the tire for
heavier riders as needed.
Brake caliper alignment/adjustment. It is common to get some noise from
brake discs if not perfectly aligned and in proper working order. This can occur
aer heavy use. Loosen the adjustment bolts and lightly position the brake
caliper on the disc. An easy method to do this is to lightly hold the brake lever
to center the brake caliper on the disc. Then tighten the bolts incrementally up
to 50 in/lbs. This can take a couple tries and may take some manual/eyeball
adjustment. The brake caliper mounting brackets (frame/fork to brake caliper
bracket) should always be securely tightened to 70 in/lbs.
BRAKE CALIPER ALIGNMENT

pg. 9
STEM, FORK, HANDLEBAR
This controls your handlebar alignment and must be snugly ed for safe
riding. The steerer tube and stem must be tight and exhibit no "play" or wobble
in the steering head. You can check this by loosening the bolts on the side of
the stem and tightening the cap bolt to pull the "stack" of steering bearings
and spacers together. Do not over-tighten the cap bolt, but the stack of
bearing and spacers on the steerer tube should be tight. Ensure that the stem is
aligned with the front wheel. Once aligned, re-tighten the stem bolts that
clamp the steerer tube. Now check alignment and angle of the handlebars and
then tighten handlebar clamp bolts. All bolts on the stem should be torqued to
250 in/lbs.
Crank bolts can come loose with excessive wear or heavy use. These should be
checked and torqued oen to 350in/lbs. Apply light grease whenever
re-assembling. Do not over tighten for risk of stripping the bolts.
CRANK BOLTS

pg. 10
Each control unit - brake levers, throle and display have bolts that tighten to secure their position on the handlebar. You can loosen these bolts to adjust the
angle of these controls and align them to a position that you nd comfortable, but should make sure they are tightened to where they don't move during use.
30-60 in/lbs. Do not over-tighten.

Wheels and Tires.
Safety.
The ZOOZ Bikes electric bicycle has 24” x 2.5” tires and tubes that are designed for durability and safety for regular cycling activities. However,
tires must be checked before each use for proper ination and condition. We recommend 30-35 PSI. Proper ination, good maintenance, and
proper care will ensure proper performance. Check the condition of the tires and rims for damage, cracks, cuts or deformation. When tire wear
becomes obvious or a hole in the tire is found, you must replace the tires and/or tubes before using the bike, otherwise injury to operators and/or
damage to your bike could occur. In addition to proper ination, correct wheel alignment helps to decrease tire wear. If you nd a tire is worn
unevenly, have a professional cycle mechanic check the wheel alignment.
A properly ing ANSI, SNELL, CE, or similarly approved bicycle safety helmet should be worn at all times when riding your bicycle, or as
recommended per your local laws. Always wear a properly-ed helmet that covers the forehead when riding a bicycle. Many states require specic
safety devices. It is your responsibility to familiarize yourself with the laws of the state where you ride and to comply with all applicable laws, including
properly equipping yourself and your bike as the law requires.
Reectors are important safety devices that are designed as an integral part of your bicycle. Federal regulations require every bicycle to be
equipped with front, rear, wheel and pedal reectors and/or lights. These reectors are designed to pick up and reect street lights and car lights in
a way that helps you to be seen and recognized as a moving bicyclist. Check reectors and their mounting brackets regularly to make sure they are
clean, straight, unbroken and securely mounted.
No liability or warranty shall be accepted if the use of the ZOOZ Bikes electric bicycle deviates from this intended use, if safety instructions are not
observed, in the event of overloading, or if faults are not properly rectied. Similarly, no liability and warranty shall be accepted in the case of
assembly errors, willful intent, accidents and/or if care and maintenance specications are not followed. Any modication or alterations to the
electrical system (tuning) voids all claims under warranty and guarantees.
Your ZOOZ Bikes electric bicycle is designed for use on paved paths only. You should therefore never ride on stairs, jump or perform wheelies or
similar activities. ZOOZ Bikes electric bicycles are not approved for participation in competitions. Commercial use does not form part of the intended
use. Operation parameters, maintenance, guidelines and service instructions described in this manual are part of the intended use.

Battery Usage and Care Details.
Brake Wear and Care.
The baery is the most important component of your ZOOZ Bikes electric bike. Following a few simple rules, you can optimize its life:
- The baery can be charged both mounted on the bike or separately from the bike. Two keys are supplied to lock/unlock and remove the baery.
- Plug the charger into a wall outlet. Connect the charger cable to the baery charging port. The baery will charge with the baery switch on or
o.
- When the charging process starts, the charger LED turns red. Once the baery is charged, the LED will turn green.
- Do not store a discharged baery. It could go into deep discharge which will reduce its life.
- Make it a habit to recharge at the end of each ride, so your bike will always be ready to ride again.
- Even if it can withstand storage temperatures of 23°F - 104°F (-10°C - 40°C), you can optimize its shelf life by storing it at room temperature
65°-75°F (18° - 23°C).
- Observe operating conditions between 40°F - 85°F (4°C - 30°C).
- Do not leave your baery exposed to high temperatures or direct sunlight for long periods of time (for example, on the back of a car in direct sunlight).
- Please ensure that the contacts are always clean and do not insert any metal objects.
- Do not dispose of the baery in your trash. There are proper disposal methods for lithium-ion baeries. Please check your local waste management
regulations.
- Keep out of reach of children.
Brakes are an integral part of the operation of your bike and must be properly maintained, adjusted and replaced if necessary. If any of the below is not
within your skill set we recommend taking your bike to an E-bike specialist or professional cycle mechanic. Hydraulic brakes require maintenance not
only on the pads and rotors but also on the hydraulic brake line. For brake pad replacement, check to see if the rotor and pads have contact with each
other. You can purchase replacement brake pads directly from ZOOZBikes.com
The ZOOZ Bikes electric bike brake orientation is as follows:
Rear brake = right lever
Front brake = le lever
On a hydraulic disc brake, pad wear is compensated for automatically. Simply check the alignment of the pads with the disc, and check that the wheel is
fully pushed back. Good alignment ensures the absence of noise and a normal wear of the pads. To ensure maximum service life of the brake
components, avoid contamination of the pads and the disc by greasy substances. Regularly check the condition of your cables, ducts or harness, and
the wear of your pads. For beer ergonomics and safety, we advise you to adjust the brake levers in a position that places it as a natural extension
of the user’s arms. If you have any questions or concerns, please contact ZOOZ Bikes.

pg. 14
Range.
The maximum range of a full charge depends on many variables such as: age of baery, type of terrain and incline, rider weight, speed, outside
temperature, driving style, amount of pedaling and tire pressure.
Range in cold weather:
- In case of extreme cold, the range of your electric bike is reduced. It is a normal physical process, and in no way a sign of damage or
defect of the baery. If you use your baery when temperatures rise, its energy will increase again.
- We advise you to store the baery and charge it at room temperature during cold days. The power consumption warms the baery and you
benet from a good baery life, even when it is cold outside. In winter, plan for shorter trips or pedal with a lower level of assistance.
Conditions that aect your baery’s range:
- Temperature: Extreme cold and heat can aect the baery’s capacity.
- Total Number of Charge Cycles: The baery has a total of 600 - 800 full cycles when it’s new.
- As the baery ages, total capacity can decrease.
- Wind: Riding into a strong headwind can decrease range.
- Road Conditions: Excessively rough or hilly terrain requires the consumption of more power.
- Load: Carrying extra cargo on the bike or in a backpack will use more energy.
- Rider Weight: The weight of the rider can aect the energy usage of the bike, with more weight requiring more energy.
- Repeated acceleration from a standing start.
- Poor Maintenance: Issues like under-inated tires, mal-adjusted brakes and a dry or dirty chain can decrease range.
Tips for Maximizing Range:
- Charge the baery at a comfortable temperature range between 65°F - 75°F (18.3°C-23.9°C).
- Lithium-ion baeries have no chemical memory, and it is not necessary to discharge the baery completely for the best performance. Charging
a partially-full baery will have no negative eect.
- Maintain proper tire pressure and lube the chain regularly.
- Operating temperatures between 40°F - 85°F (4°C - 30°C) will signicantly increase range.
