PART FOUR

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.

2. Protection

To extend the battery life and be Intelligent Use of li-ion battery, here are the regulations:

Firstly: Requirements on charging and discharging

A. charge: the charger must be the assorted one. First, connect the power to the charger. second,insert the charger’s out-put connector to the battery’s in-put connector. Third, when the signal light is on,please pull out the battery’s in-put connector first. The common single charging time is about 6-8 hours.if the battery be blow-up, the charging or discharging must be stopped.
B. avoid over discharge: charge the battery timely after discharging, in order to avoid the over-discharge.

Secondly: Requirements on storage

A. Lion-battery cannot be stored at the place where is over hot and over humidity. therefore the temperature of the storage should between -20 to 55degree, and further more the storage must be kept in dry, clean and the battery should not be piled up.
B. the battery cannot be stored for a longtime without charging. The battery should be charged once a month. The battery should be stored with fully charged.

Thirdly: Maintenance

A. When you test the voltage of the single piece of the battery-cell, you have to test the cell directly, not by the wire. By doing that, it can avoid the voltage decline.
B. You have to wear the gloves or clip the finger nails before you take out the single piece of the battery. So as to avoid damage the cover of the battery.
C. Forbid bending the battery cell,the top edge of the seal-up. And also the falling, hitting and short circuit are prohibited.
D. When you re-assemble the battery,there are some special notes we have to concerned in mind.

WARNING:
Always do the Mechanical Safety Check before you get on a bike. Be thoroughly familiar with the controls of your bicycle

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.

Tires

Pump tires 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.

1. 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.

2. 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 meters; this can increase to 15 meters 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 keeps 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 practice 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 tires, brakes and gears monthly

Check the tire pressure; make sure it is enough at least 40 PSI. Inch and preferably 50 (Compact) or 60 PSI. Low tire pressure will make the bike less efficient and will easily damage the tires.

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.
If you are unsure about brake, gears or chain adjustment, take the bike to be serviced at your local cycle 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.
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.

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.
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 obtained from suppler.
The battery is deemed to have reached the end of its life when achieving only 40% of its original capacity.
