MAINTENANCE AND CHECKS
MAINTENANCE AND TUNE-UP
For your safety and comfort, we recommend that your ebike undergoes regular maintenance and tune up by our authorized specialists.
Note: All bikes go through a normal break-in period. That’s why we recommend all our riders to get a quick tune up one month after purchase so that our specialists can adjust cables and other key parts.
Below is our recommended tune-up frequency based on how often you ride:
1. Heavy Rider, rides 25 km (15 mi) or more daily, we recommends to have at least monthly tune-up and daily check ups
2. Recreational Rider, rides once or twice a week, we recommends to have at least quarterly tune-up and weekly check ups
3. Light Rider, rides once or twice a month, we recommends to have at least half-yearly tune-up and monthly check ups
Check and maintain your Pedal Assist Electric Bicycle periodically to ensure smooth and safe riding.
Clean the exterior with damp clothes and wipe clean. Do not spray with water.
Store the bicycle in the cool and dry place.
Before riding, check that all the safety pins are well secured, all mechanicals and electricals components are functioning properly. Ensure the brakes are functioning well and the tires properly inflated.
Check for loosen or worn out parts and do not operate your bicycle until they are repaired or replaced by your authorised dealers.
Air escapes and tires lose pressure over time affecting speed, comfort and safety. Therefore we recommends you to check your tires every time before riding.
When pumping up, stay within the recommended tire pressure range which should be stamped on the sidewall of your tires (from 35 psi to 60psi). Inflate to the upper limit for a faster ride. And to the lower limit for a smoother ride.
As with most things in life, moderation is a virtue. Don’t under-inflate nor over-inflate.
RECOMMENDED CHECK UPS BEFORE RIDING
Tyre. Checks the tires pressure and the thread ensure safe to use, clean when necessary.
Wheels. Check the position and true, and tighten the quick release.
Brakes. Checks the brakes, the brake pads level, and ensure they work properly. Clean the disc and rim with cleaning solutions.
Electric. Checks the battery, has it been fully charged and regularly maintained?
Bolts and Nuts. Checks for any loose bolts and nuts and tighten when needed
Position. Check for heights and riding position.
Safety. Checks safety gears like lights, helmets, etc
Chain and Pedals. Checks the chain, lube and clean regularly
Cables. Check for any loose or torn cables and rectify.
BATTERY AND SAFETY PRECAUTIONS
Charge the battery pack for at least 6 hours before using your new pedal assist bicycle for the first time or until the charge led on the charger turn green.
To install the battery, slide the battery pack onto the bike rack steadily and then lock it into the rack with the supplied key.
Switch on the battery power when ready for usage. Switch off the battery power when the bicycle is not in use.
The battery pack works properly at the temperature range of 5º C to 30º C. The running mileage will shorten if used outside of this temperature range.
Remove the battery pack if the bike is not used for an extended period of time, or if it is stored outdoors to prevent the battery from over exposure to excessive sun or rain.
Store the battery pack in a cool, dry and ventilated place with temperature between 5º C to 30º C.
If the battery is found overheating, leaking, deforming, giving out, has an odd smell, or is smoking, stop using the battery pack immediately.
Do not use the battery pack on other applications or to power other products.
Use only the supplied battery and the specified adaptor to charge the battery.
Using uncertified, non-recommended adaptor to charge the battery pack may cause irreparable damage and void the warranty.
Keep the battery pack away from children’s reach.
For long term storage, the battery should be charged at 60%-80% capacity (about 3-4 hours). Repeat the same procedure every 2-3 months.
The battery pack should be charged promptly when the power is low, to avoid damage caused by battery self-discharge.
Do not use chemical solvent to clean the case of the battery pack or adaptor.
Use a soft cloth to wipe and clean any waterlogging or dirt on the surface of the battery pack and the adaptor.
Do not expose the battery for long periods of time to rain or strong sunlight.
Do not place the battery pack in a humid environment or submerge in water.
Do not put the battery pack into fire.
Avoid over-loading the bicycle over 100kg including rider and cargo.
20. Avoid extended climbing of hills over 15 degrees steep for over 15 minutes
BATTERY TEMPORARY EFFECT
Voltage depression due to long-term over-charging
A common process often ascribed to memory effect is voltage depression. In this case, the peak voltage of the battery drops more quickly than normal as it is used, even though the total energy remains almost the same. In modern electronic equipment that monitors the voltage to indicate battery charge, the battery appears to be draining very quickly. To the user, it appears the battery is not holding its full charge, which seems similar to memory effect. This is a common problem with high-load devices.
Voltage depression is caused by repeated over-charging of a battery, which causes the formation of small crystals of electrolyte on the plates. These can clog the plates, increasing resistance and lowering the voltage of some individual cells in the battery. This causes the battery as a whole to seem to discharge rapidly as those individual cells discharge quickly and the voltage of the battery as a whole suddenly falls. This effect is very common, as consumer trickle chargers typically overcharge.
The effect can be overcome by subjecting each cell of the battery to one or more deep charge/discharge cycles
So it is recommended to use once a while it untill the battery left a quarter before charging it again
BATTERY AGE AND USE - NORMAL END-OF-LIFE
All rechargeable batteries have a finite lifespan and will slowly lose storage capacity as they age due to secondary chemical reactions within the battery whether it is used or not. Some cells may fail sooner than others, but the effect is to reduce the voltage of the battery. Lithium-based batteries have one of the longest idle lives of any construction. Unfortunately the number of operational cycles is still quite low at approximately 400-1200 complete charge/discharge cycles. The lifetime of lithium batteries decreases at higher temperature and states of charge (SoC), whether used or not; maximum life of lithium cells when not in use(storage) is achieved by refrigerating (without freezing) charged to 30%-50% SoC. To prevent overdischarge battery should be recharged to 50% SoC once every six months or once per year
Inspect and tighten the front wheel hub
Check for unusual vibrations or scretching sounds
Inspect and tighten front brake
Clean the disc regularly to avoid jerky braking
Inspect, tighten and adjust rear brake when needed
Inspect and secure the latch properly
Tighten the screws and bolts when loose
