Using Gears

Some model bicycles are equipped with gears. Gears are used to change the ratio between rotations of the rear wheel and the crank set. This enables you to pedal less and travel faster on ﬂat or downhill sections, or pedal faster and travel slower to climb hills. Gearing is independent to pedal assistance, so pedal assistance operates the same regardless of selected gear. Remember, however, that pedal assistance is ” governed” by overall speed.
The selectable gears are located on the rear wheel, known as a “gear cluster” or “cassette”. The larger the gear, the smaller number of rotations per rotation of the crank. The largest gear is the “lowest” and is referred to as “1”. As each gear becomes smaller, it is a “higher” gear then the previous and is numbered sequentially. The number of gears may vary between different models. Beneath the gear cluster is the derailleur mechanism, which moves the chain, so it runs on different gears. The derailleur is operated by the rider using controls mounted on the handlebars. The gear change is “indexed” so each gear selection positively engages – this is factory set and should require no adjustment. There may be slight variations between bicycle models in method to change gear ” up” (from a lower gear to a higher gear), or to change gear “down” (from a higher gear to a lower gear).
The image shows a “7-speed” type that uses a button for changing up gears (push button to activate derailleur), and a lever for changing down gears ( rotate lever forward to activate derailleur).

Guidelines for Using Gears

To get the best performance and service life from the gear change system, understand and apply the following techniques:
You MUST be pedaling during gear changes.
Do not attempt to change multiple gears in a single action. Allow each gear change to complete fully before the next change.
Always use an appropriate gear for your speed, the terrain and incline. This helps you ride most eﬃciently.
Keep the chain and gears properly lubricated and clean.
If you notice noise after changing gear or an ability to select a gear or the chain not running smoothly, have the gear system inspected and adjusted by a bicycle mechanic or suitably qualiﬁed person.

Using Brakes

All bicycle models are equipped with a front and rear wheel braking system. Brakes are used to slow the bicycle down. The braking systems may use different mechanics; however, the functionality is the same, and that is to change the energy of the moving bicycle into heat energy (“friction” ):
For disc brakes, this means pads made from a special friction material pinching against a disc mounted to the centre of the bicycle wheel.

GO-GO-BEST-GM30-Electric-Bicycle-15

The brakes are operated by the rider through levers mounted to the handlebars, The left-hand lever operates the front brake, the right- hand lever operates the rear brake. The ability of the rider to adequately slow and/or stop the bicycle depends largely on the skill of the rider, the surface being ridden on and other factors such as rain, tires, adjustment and condition of the brake parts etc.

Guidelines for Using Brakes

To get the best performance and service life from the brake system, understand and apply the following techniques:
In wet conditions, which reduces friction, always provide additional distance for braking and adjust how quickly you apply the brakes.
When applying the brakes, particularly the front brake, use a lower pressure to start with until you feel the brakes starting to “ bite”, then increase pressure as required.Do NOT over-apply the brakes and cause the wheel to stop rotating – this may result in loss of control.
Maintain the brake friction components (pads, shoes, rubbers) in good condition and replace when they reach the wear limit.
Maintain brake adjustment so that the brakes perform eﬀectively, the levers are comfortably positioned, and there is not excessive play in adjustable components.
If the brakes are not performing eﬀectively, making abnormal noise or any part is not serviceable or cannot be adjusted correctly, have the brakes inspected and adjusted by a bicycle mechanic or suitably qualiﬁed person.
If the brake cables become frayed or otherwise damaged, have them replaced by a bicycle mechanic or suitable qualiﬁed person.

Maintenance

Some maintenance activities described may be beyond the scope of some users. Do NOT attempt procedures that you are not comfortable with, or do not have the necessary tools, experience or knowledge for – take the unit to an authorized service center or qualified technician for servicing. Items in the maintenance schedule below that are recommended to be performed by a qualified technician are highlighted yellow.

Failure to follow the maintenance recommendations, using incorrect or non compatible accessories or replacement parts, or general negligence may result in making the product warranty void. Improper adjustment or service may result in damage to the bicycle or make it hazardous.
Maintenance requirements may be affected by any number of factors from your riding style to geographic location.
When new, parts of the bicycle may “break-in” over the course of the first approximate 100km of riding, possibly including the stretching of cables, spoke tension changes etc. It is recommended to have the bicycle inspected and serviced at an authorized service center or by a qualified technician.
The bicycle components are subject to wear and stress. If a component is weakened through stress, age etc., it may fail without warning. It is important to regularly inspect the bicycle for any signs of component fatigue – look for cracks, fraying, discoloration etc., as this may indicate that a part is near the end of its useful life and should be replaced.
Clean the bicycle with a soft, damp cloth – do NOT use high pressure water cleaners or hoses, pressured air, solvents, abrasives etc. For the console, battery and motor, do NOT use any liquids.
When transporting in a vehicle, it is recommended to have the battery out of the bicycle during transport.
Store the bicycle where it will be protected from rain, sun etc. to help prevent corrosion, fading etc.. For safety, longest possible service life and reliability, maintain the bicycle properly. Use the components before each ride. The proper condition and function of these Systems is critical to your maintenance schedule below for guidance. It is very important that you check certain systems and safety.

Battery Storage

When storing the batteries for a long period of time:

Charge the batteries at least every 30 days to avoid capacity loss. Batteries slowly self- discharge when unused over a long period. If the battery cells are left at a critically low charge state, the lifespan and capacity will be permanently reduced.
Always disconnect the charger from the mains electrical supply and battery before storing the battery.
Avoid storing batteries in extreme temperatures, whether hot or cold. The recommended battery storage temperature is between 0 and 25 ° C (32 to 77 ° F). Avoid exposing batteries to temperatures at or above 40°C (104°F) for extended periods.
Batteries are best kept in a cool, dry place. Do not allow batteries to accumulate condensation, as this may cause shorting or corrosion.

Battery Fuse
Use fuses of the same type only – the rating (in Amperes) is printed on the end of the fuse. . If the fuse”
blows” regularly, have the bicycle inspected at an authorized service Centre.
The bicycle battery/ electrical system may feature fuse protection to prevent damage in the event of a short circuit, overload or over current situation. For example, if the electrical system is exposed to excessive moisture. On some model bicycles, the fuse is accessible and can be easily replaced. If the fuse is “blown”, the bicycle electronics will not be available until the fuse is replaced. To replace the fuse:

Using a suitable screwdriver, remove (rotate left) the fuse holder on the battery pack until fully unscrewed, then pull the fuse holder and fuse from the bicycle.
Discard the blown fuse. Insert the replacement fuse into the fuse holder.
Insert the fuse and fuse holder to the bicycle, and re install (rotate right) the fuse holder until fully.

Tyre Pressures
The tyres must always be inﬂated to the correct pressure (as speciﬁed on the tire sidewall) before every ride. Riding the bicycle with either too low or too high pressures will aﬀect bicycle performance, may aﬀect eﬀective electrical assistance range, and may render the bicycle as dangerous. Use an accurate pressure gauge when checking pressures.

Chain Care
The chain periodically requires lubrication, depending on frequency of use and conditions etc.
If the chain is noisy or running roughly, lubricate it by applying a small amount of bicycle chain lubricant to it.
Do not allow the lubricant to get on to the tires.

Torque Settings
It is important to regularly check all fasteners for adequate tightness. The following are considered highly important and should be adjusted to the speciﬁed torque values using a suitable bicycle torque wrench, sockets and adaptors. Depending on bicycle model and design, some fasteners listed below may not be applicable:

Front Axle Nut – 35Nm
Rear Axle Nut – 35Nm
Handlebar Clamp Bolt – 10Nm
Handlebar Neck Lock Bolt – 15Nm
Handlebar Stem Bolt – 24Nm
Pedal Bolts – 35Nm
Brake Calliper Mounting Bolt – 7Nm
Brake Cable Anchor Bolt – 7Nm

Frequently Questions &Answers

Q: Is it normal for batteries to get warm when charging?
A: Yes, it is normal that the batteries will become warm during the charging process.

Q: How long will my batteries last before needing replacement?
A: Average battery life depends on use and conditions. Even with proper care, rechargeable batteries do not last forever. Generally, lithium-ion batteries will last more than 800 charge discharge cycles. A partial charge/discharge counts fractionally against those numbers;
discharging the battery to 50% then recharging it completely uses up one half of a charge cycle. “End of useful life” refers to the point at which a battery can no longer supply 60% or more of its original rated ampere-hour (Ah) capacity. A this point, degradation of the battery being able to be fully charged accelerates and the battery will need to be replaced.

Q: What happens if the battery discharges while riding?
A: Pedal assistance will stop when battery charge reaches a minimum level (check level on the console,if applicable). Lights (if applicable) may still function for a period. Your bike can be ridden without pedal assistance.
