Before riding you should first read the section below: “Riding your e-bike”
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, such as TNT, please carefully inspect
the packaging for any signs of damage or mishandling during transport.
We insure all bikes against damage caused during transport via couriers, but this insurance
ceases once you accept the carton. If in any doubt about the security of the carton received
sign any delivery note as “not yet inspected” to preserve your right to claim for damage
caused during transport from us to you.
For all bikes, inside the carton alongside the main frame and rear wheel assembly, you
should find:
Front Wheel, seat and post, charger box containing your battery charger, mains lead
and front light. The battery should be locked into its frame compartment. The
handlebars will be loose and taped to the side of the main frame of the bike.
All the main parts will have been carefully wrapped and protected when first put into the
carton. You should try to preserve the wrapping materials and the carton itself, just in case
you need to return the bike to us via a courier.
Tools Needed:
A set of Allen keys, an adjustable Spanner and a Philips screwdriver should be all you
need to assemble your bike.
General considerations:
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 an ideal place to build your bike, especially if
you can clamp the frame or have a friend that can help. Kneeling around a cluttered floor is
not ideal!
Clear some space and make plenty of time to complete a careful assembly.
Handle bars
If your bike is up on a table, rather than the floor, you may want to start by fitting the
handlebars, but there is no particular sequence to assembly and you may equally start with
another component.
The Classic handlebars fit into the tube at the top of
the front forks.
Tighten in two places: through the hole exposed when
tilted forward, and underneath the adjustable stem.
The Sport and Merlin handlebars fit into a clamp.
To raise or lower the angle of the Sport handlebars, loosen the bolt at the underside of the
stem, adjust and then re-tighten.
Front wheel, mudguard and lamp
It’s best to fix the front mudguard and lamp before fitting the front wheel.
One bolt attaches both the lamp and the top of
the mudguard.
Pass the lamp cable through the bracket and
attach to the two spade connectors.
Tighten the lamp using the screw at the side
Tighten the two screws holding the rear stays of
the mudguard
The front wheel has a quick release mechanism on the Classic and Sport ranges.
To insert the QR into the front wheel correctly:
1. Ensure the QR mechanism is centred
the right hand side.
on the fork recess. The lever should be on
Use the nut to pre-tighten the mechanism into the recess NOT the lever.
3. Fully tighten the mechanism, finishing with the lever upright, just beyond parallel to the
forks, behind the fork blade, and be as tight as possible.
After fitting the wheel, take some time to check the bolts that secure the disk. Ensure they are
in place and as tight as possible.

You should fully charge your battery, before going for a ride
for the first time.
The battery can be charged either in the bike, or taken out of
the bike.

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.

Looking through the spokes you will see the inner
pad adjuster…
This moves the inner pad closer to the disk rotor.
Every few months…
3b, 3a
By loosening the whole calliper (1a and 1b) the outer pad can be moved closer to the disk
You should only need to move the calliper closer to the rotor by a small distance = < 1 mm
Make sure the two bolts holding the calliper are properly tightened after adjustment.
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.
First select and line up the chain with gear 1 and then check again using the highest gear.
Turn the adjuster clockwise to move the derailleur and
so guide the chain to the right, anticlockwise to guide it
further to the left.
As a final check, please complete the following checklist to make sure your bike is properly
assembled and safe to ride:
 Ensure handlebars are straight and secure and all relevant bolts are tight.
 Test that they are securely attached to the forks by gripping the front wheel
between your legs and attempting to turn the handlebars.
 Ensure the front and rear mudguard stays are tight.
 Check that the quick release mechanism is tightly gripping the front wheel.
Seat and post
 Ensure that the seat is straight and secure.
Pedals and chain
 Ensure the pedals are wound in fully and are nice and tight. Use a spanner if
 Ensure that the gears go in cleanly and that the gear adjustment is correct
 Test front and rear brakes whilst rolling the bike forwards – both wheels should
stop completely.
 Test that there more than a finger’s width between the grip and the brake lever
when fully depressed.
 Ensure that the rack is secure and that all visible bolts are tight.
 Rock the bike gently from side-to-side to ensure that the kickstand doesn’t
wobble. Tighten the bolt on the frame directly above the kickstand if necessary.
 Pump the tyres to the point that they are very firm and impossible to deform with
your thumb. This is equivalent to roughly 60ppi of pressure for the Sport and
Classic models and 50ppi for the Urban.
Test the front and rear lights using the control on the handlebars.
Test the pedal assist function by rotating the pedals with the rear wheel raised.
Test the throttle with the rear wheel raised.
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 that all lights and meters 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 then check that this is
properly tight in its position within the front forks. Quick release
mechanisms can more easily work loose than conventional axles and so
should be checked more often for tightness.
Make sure that 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, mount the bike, placing one foot ready to pedal,
check that it is safe to proceed, and then set off. You will feel the
motor as 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
accumulating over 10 miles.
Use both brakes together when stopping; don’t use only one.
Remember 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 will increase to 15 metres on
wet or snowy roads.
Don’t ride through deep puddles or streams. Ensure that water never
reaches the motor and controller level.
Don’t ride on 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 may damage the
motor and battery.
Don’t ride under the influence of drugs or alcohol, or when feeling unwell.
Don’t ride at night without lights. If the lights are not working it may be
safer to get off and walk with the bike.
Don’t allow the bike to be used by young people under 14 years. 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 newsagents sell it.
Cycle training courses for adults and young people are run nationally. For
more information call the cycle training hotline on 0870 607 0415 or visit
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
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
Check the tyre pressure; make sure it is enough at least 40 LBs Sq. Inch
and preferably 50. Low tyre pressure will make the bike less efficient and
damage the tyres.
Brake adjustment:
1. Check the right brake bar at full reach.
2. Loosen the brake bolts, tighten or loosen the brake wire and set the brake
pad distance at about 1 mm, and refasten.
3. If the gap for the two sides is not the same, adjust each pad adjuster until
they are the same.
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.
If you are unsure about brake, gears or chain adjustment, take the bike
to be serviced at your local cycle shop.
Lithium Battery Care:
When receiving the battery from new, fully charge it on a regular charge and it will be ready
for use.
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, at least once
every two months and just before your next journey.
Letting the battery run empty on a regular basis will shorten its lifespan considerably.
Never charge the battery in freezing conditions. If the battery has been used in very cold
conditions, allow it to warm up before charging.
If storing the battery for any length of time without use (over the winter say), try to keep it at
around 50% charge, in a cool place inside, and if possible top up the charge a little every
month or two. 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
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 place on the bike, if
using this method ensure that the main power key is in the off position.
Ensure that you allow adequate time for charging: 4-6 hours is needed for a full
To charge the battery: first connect the output plug of the charger properly with the
charging socket of the battery and then connect the input plug of the charger with the
mains supply. When the red light is on charging is taking place.
When the light changes from red to green the battery is fully charged. After charging
disconnect the charger from the battery case.
Always charge the battery indoors and away from damp areas or where water is
used. When charging keep both the battery and charger away from flammable
materials or products. The charger will heat up when charging.
Our lithium batteries, if treated correctly, will have a long life. At the end of its life, the
battery should be recycled and a replacement can be bought from The battery is deemed to have reached the end of its life when
achieving 40% of its original capacity.
