Quick Start
If your bike has been checked over by someone competent and you’re
ready to ride, here’s how to switch it on:
1. Switch on the battery. Silver Battery: turn the key
clockwise, all the way to the right (position 3).
The In-Frame Battery does not need a key (put it
somewhere safe).
2. Switch on the display: hold down the Mbutton (not needed on
older displays).
3. If you have a throttle you can push in the button (safer when
astride the bike) to operate the motor without pedalling.
4. If you have an LCD upgrade display take a look for our specialist
manual at JuicyBike.co.uk You can find the latest version of this
manual there too.

Speed settings
Pedalling can be made easier by changing the gears, as you ride…
Change the motor speed using the +and –buttons as you pedal…
Walk assistance
Our latest displays offer a low speed “cruise” setting, for use only when
walking alongside your bike. To activate walk assist, hold down the –
button. After a few seconds the bike will start.

Assembly
If your bike has arrived boxed, then follow these
guidelines for assembly.
Delivery inspection
If you have taken delivery of a Juicy Bike via a courier please carefully
inspect the packaging for any signs of damage or mishandling.
We insure all bikes against damage caused during transport via couriers,
but this insurance ceases once you accept the carton. If in any doubt sign
any delivery note as “not yet inspected” to preserve your right to claim for
damage caused in transit from us to you.
Inside the carton you should find the main frame and rear wheel assembly,
front wheel, seat and post, charger box containing your battery charger,
pedals and lights. The battery should be locked into its frame
compartment. The handlebars will be loose, strapped to the side of the
bike.
All the main parts will have been carefully wrapped and protected when
first put into the carton. You should keep the wrapping materials and the
carton itself, just in case you need to return the bike to us.
Tools Needed:
A good set of Allen keys, an adjustable Spanner and a Philips screwdriver
should be all you need to assemble your bike.

Ideally…
Allow yourself plenty of time to put your bike together carefully.
You should be confident that you have the skills required to safely prepare
the bike for use and are able to carefully check that everything functions
correctly and safely, before using the bike. It is not expensive to have your
bike assembled at a local bike shop where you should find experienced
and responsible bike mechanics. So if you have any doubts consider using
a professional.
At a bike shop your bike would be assembled using a purpose built stand,
at eye level. At home a bench or table with space all around is a good
place to build, especially if you have a friend that can help hold the bike.
Kneeling around a cluttered floor is not ideal!
Clear some space and make plenty of time to complete a careful assembly.
A cup of tea might also help…

Handle bars
For our larger wheeled bikes the handlebars are inserted into the front of
the frame. Our Compact Folding Bike has them already attached.
Put the handlebar stem into the frame, lift the adjuster and rotate forwards
to reveal the hidden bolt.
You may also need to tighten the bolt
underneath the front of the adjuster clamp.
For bikes with mono-shock suspension:
First, the forks need to be pulled up into the frame (1), then the handlebar
stem clamped tight (2)

Mudguard, lamp then front wheel…
It’s best to fit the lamp and front mudguard before fitting the front wheel.
1. Pass the lamp cable through
the bracket and attach to
the two spade connectors.
2. One bolt attaches both the
lamp and the top of the
mudguard.
3. Firmly tighten the lamp using the screw at the side
Tighten two screws holding the mudguard stays
Front wheels may have an optional quick release (QR)
mechanism.
To insert the QR into the front wheel correctly:
Ensure the QR mechanism is centred in the recess cup.
1. Use the nut to pre-tighten the mechanism NOT the lever.
2. Then push home the lever, as tightly as possible.

11
Your bike may be supplied with a theft deterrent
(secure) QR, which requires a tool for removal.
Ensure the Secure QR mechanism is centred on the fork recess cup.
1. Finger-tighten the nut into the recess.
2. Fully-tighten, using a short hex key, as tight as possible.
Our Compact bike front wheel is fitted with a standard
nut and locating washer…
Make sure the small
washer locates into the
forks.
Tighten using a 15mm
spanner
Finally:
Check the wheel runs true centred in the forks.

Seat Post
Is easy to fit…
But do make sure it doesn’t twist or droop whilst riding
by tightening the adjuster. There is a mark showing the
maximum height upto which the post may be set. Do
not exceed this max height.
Charging the battery
Fully charge your battery before your first ride.
The charger light will
change from red to
green when the battery
is fully charged.
Then switch off and
remove the charger.
Removing the battery
The battery can be charged in or out of the bike.
Push the key in and turn fully anti-clockwise to unlock
the battery from the bike.
Take care putting the battery back into the bike:

13
Make sure the slide rail is
positioned into the battery
groove…
Turn the key clockwise to lock the
battery into the slider.
In-frame batteries…
Turn the key and lift the handle
A charging port can be found at the
base of the battery

14
Fitting the rack
1. Loosen the top and side bolts
2. Attach the stays to the frame
3. Tighten the bolts again

Regular Adjustments
Disk Brake adjustment
Your brakes will need regular attention to ensure they operate correctly.
As the pads get used you will need to adjust them to stay close to the
metal rotor. A bike shop is the best place to have your brakes checked and
adjusted, but if you need to do this yourself here’s how.
Every few months (depending on use)…
Looking through the spokes you will see
the inner pad adjuster…
Use a hex key to move the inner pad
closer to the disk rotor.
The outer pad can be quickly adjusted
closer by unwinding the cable adjuster
(anti-clockwise) at either the brake lever or at the calliper.
Hydraulic brakes need no adjustment serviced by a qualified mechanic.
Gear Adjustment:
A noisy gear, or poor gear selection, is often because the chain is not lined
up precisely with the cogs. Looking from the back of the bike, line up the
chain using the adjuster.
Line up the chain with gear 1 and then check again using the highest gear.
Turn clockwise to guide the chain to the smaller gears on
the right, anticlockwise to the larger on the left.

16
Finally… check everything
This checklist will help make sure your bike is properly assembled and safe
to ride:
Handlebars
Check your handlebars are straight and secure. To check, grip the
front wheel between your legs and try to turn the handlebars.
Wheels
Make sure the front and rear mudguard stays are tight.
Ensure the quick release mechanism is properly gripping the front
wheel.
Seat and post
The seat and post should be straight, fastened tightly and not exceed
the max height indicator.
Pedals and chain
The pedals should be wound in and fully tightened.
Gears should engage cleanly and change smoothly.
Brakes
Test front and rear brakes whilst rolling the bike forwards – both
wheels should stop completely.
Check there is more than one finger thickness between the grip and
the brake lever when fully depressed.
Rack
Ensure that the rack is secure and that all bolts are tight.
Kickstand
The kickstand shouldn’t wobble. Tighten if necessary.
Tyres
Pump tyres to very firm (impossible to deform with your thumb). PSI
should be 60 for our large bikes and 50 for Compacts.
Electrics
Test both lights.
Fully charge the battery before use.

Before riding
Adjust the height of the handlebars and saddle to suit the rider, whose
toes should be able to just touch the ground.
Check all lights and displays are working.
Check regularly to ensure that the electrical connectors between the
bike and battery are clean.
Check the brakes: this can be done by putting the front brake on and
pushing forwards. Do the same with the back brakes. The bike should
not move and the brake levers should not touch the handlebars. The
brakes should work without having to press down too hard on the
handles.
If your bike has a quick release on the front wheel check it is fully
tightened and the wheel is running true. Quick release mechanisms
can more easily work loose than conventional axles and so should be
checked before every ride.
Make sure your clothing is suitable for riding. Long, loose or flowing
garments may become caught in the wheels or chain.
Wear an approved safety helmet.

Riding your e-bike
After mounting the bicycle, turn on the main switch, the power display
light will come on, indicating power is connected. Release the
kickstand.
Placing one foot ready to pedal, check that it is safe to proceed, and
then set off. You will feel the motor just after you begin to pedal.
As you cycle, the battery power will be used up, and the power level
indicator lights will go off in turn. If the battery becomes flat, turn off
the main switch and use pedals only to ride, recharge fully after
journeys have accumulated over 10 miles.
Use both brakes together when stopping.
When riding in wet conditions your brakes will be less effective and a
greater stopping distance is needed. In dry conditions your stopping
distance should be less than 4 metres; this can increase to 15 metres
on wet or snowy roads.
Never ride through deep puddles or streams. Ensure that water never
reaches the motor and controller level.
Avoid loose or uneven surfaces, up and down kerbs and watch out for
unexpected pot holes.
Don't carry extra passengers or heavy loads, as this will damage the
motor and battery.
Never ride under the influence of drugs or alcohol, or when feeling
unwell.
Always ride with lights at night.
The minimum legal age for riding an electric bicycle in the UK is 14
years.
Please follow the Highway Code for the safety of yourself and others.
If you are new to cycling or an inexperienced rider, find a quiet place
to practise and gain confidence before trying to ride on busier roads.
Buy a copy of the Highway Code; most good newsagents have it.

Bikestorageandmaintenance:
Don’t leave the bike in the rain for long periods, or in damp conditions:
always store in a dry place.
Don't leave the bike in direct sunlight for long periods, as this may
cause some of the electrical components to overheat and result in
operation failure.
Warning:
Don't tamper with, or disassemble complex electrical components.
Don’t touch the bottom of the battery case with keys or other metal
objects in case they damage the electrical connectors between the
bike and battery.
Keepyourbikeclean
Use a degreaser detergent, or a specialist chain-cleaning product to clean
and oil your chain. A properly cared-for chain can make a bicycle more
than ninety eight per cent efficient at converting kinetic energy into moving
your bike forward. Juicy Bike chains are stainless steel and need very little
oil. Too much oil can pick up grit and so increase wear. We recommend
Green oil’s, Clean Chain degreaser and a little Chain Lube.
Checktyres,brakesandgearsmonthly
Check the tyre pressure; make sure it is enough at least 40 PSI. Inch
and preferably 50 (Compact) or 60 PSI. Low tyre pressure will make
the bike less efficient and will easily damage the tyres.
Brakeadjustment
Brake levers should operate the brakes easily with only a small
amount of travel at the handlebars. If there is not enough room for
two fingers between the lever and the handlebars then adjustment is
essential. See how to adjust above.
Chainadjustment
The chain may become looser after a long period of use and can only
be adjusted by removing links, which is best carried out at a bike
repair shop.

Lithium Battery Care
You should fully charge your new battery before your first ride.
In regular use, keep the battery fully charged after every few short rides. If
possible try to keep the battery between 50 and 95% charged, charging
after 10 miles or so.
Make sure you charge at least once every month.
Try to charge just before a journey, rather than keep your battery at 100%.
Letting the battery run empty on most rides will shorten its lifespan
considerably – it would be better to plan your battery size so regular,
everyday journeys use about 50% of your battery.
Never charge the battery in freezing conditions. If the battery has been
used in very cold conditions, let it warm to room temperature before
charging.
If storing the battery for any length of time without use (over the winter
say), try to keep it at around 60-80% charge, in a cool place inside, and top
up the charge a little every month. This will decrease the aging process of
the battery (although every battery will slowly age whether used or not).
Lithium batteries deteriorate more quickly when stored at higher
temperatures and when repeatedly fully discharged.
When returning to use, charge the battery fully to prepare it for everyday
use.
Keep your battery out of the weather whilst not riding the bike, preferably
in a cool place inside.
Always use the charger supplied with the bike. Before charging, check that
the rated input voltage matches the voltage level for your country. (For the
UK it is 240V/50 AC)
Don’t open the charger case for any reason.
To recharge the battery: tip up the seat, unlock the battery, remove and
connect to charger. Alternatively the battery can be recharged while still in
the bike, just make sure the bike is switched off.
A full charge can take between 4 to 6 hours before the red charging light
turns green. The charger will get quite warm whilst charging.
When the light changes from red to green the battery is fully charged. After
charging, disconnect the charger from the battery.
