Instructions

1. Please read the manual carefully before using your EMOJO electric bicycle.
2. Make sure all parts are locked tightly, such as the frame joint, handlebar, seat post and pedal, etc. before using. Do not use electric bicycle before carefully reading the instructions and knowing about the performance of the electric bicycle. Do not lend the electric bicycle to anyone who does not know how to operate it.
3. Develop a habit of charging when the power of the battery pack shows a red light. Please charge and maintain the battery pack consistently to have longer service; if the bicycle is not to be used for a long period, it is suggested to turn power of the battery pack to the OFF position and charge-discharge the battery once per month.
4. Frequent braking, starting, uphill, still starting, muddy and uneven ground, overloading of people and goods will assume larger electricity, thus influencing the travel mileage. If you want to get the best travel mileage, we suggest you follow the following instructions: Ride the bicycle to a certain speed by pedalling prior to turning on pedal-assist or throttle power. Try to decrease the frequency of braking and starting while maintaining safe riding habits. Please assist with pedal when the slope angle is steep, or the wind speed is fast.
5. When you lift the battery, please do not insert any metal objects (such as wires, keys, etc) into the charging socket or bridge the negative and positive poles of the battery cell. This can cause battery short-circuit, resulting in a fire and putting your safety at risk.
6. This e-bike is not intended to be ridden through water. When the water level inundates the controller, electrical circuitry or motor hub, it is possible that it will cause short circuit and damage the circuit, please pay attention to avoid burning down the electronic control system!
7. The standard load weight of this bike is 230 lbs. (including the cyclist), overloading may cause the travel mileage to decrease, or cause the spare parts of the bike damage and reduce working life of battery.
8. Warranty will be void if a non-approved battery charger or other non-original EMOJO spare parts are used.
9. Minors, pregnant women or anyone that does not have full dexterity of hands and legs should not use this product.

Main Technical Parameters

Hand Throttle Control

Your electric bike is equipped with a power and throttle control on the right hand side. To power on your bike first make sure the switch to your battery is in the ON position.
You control the throttle by pushing with your thumb the paddle, the farther you push from its resting position, the more power is delivered to the motor to accelerate. When you want to slow down, you simply release the throttle and let it return to its resting position and simultaneously apply the brakes.

When the pedal assist mode is set to “0”, the pedal assist and throttle function(s) do not engage. When the pedal assist mode is set to “5” the pedal assist function does not engage and the throttle will accelerate the bike forward. The throttle control is operated on the right hand side. You control the throttle by twisting it from its resting position. The farther the throttle switch is from its resting position, the more power is delivered to the motor to accelerate e-bike. When you want to slow down, you simply release the throttle and let it return to its resting position and simultaneously apply the brakes.

Gears
This EMOJO electric bike is equipped with 7 mechanical gears in addition to the pedal assist levels. The first gear is for easier and uphill pedalling, the last gear is for maximum speed on levelled or downhills. Change gears only when pedalling. The rear wheel contains seven chain sprockets. When the chain is around the largest sprocket, you are in the 1st gear which is the “lowest” gear. The high gear will have the derailleur positioned so that the chain is directed around the smallest gear selector and cause it to change gear. Adjustments require fine tuning and should be made by a qualified technician. Avoid changing gears rapidly from 1st to the 7th gear or vice-versa. If you change multiple gears too quickly, you could have the chain come off the front sprocket.

Correct Operation Stages

! Warning:

“For your safety, please practice in a closed track the first time you ride the Giga Bike” After mastering the controls of an electric bicycle, you may ride on regular roads and follow the traffic rules consciously. Do not let inexperienced people ride the electric bicycle, do not disassemble and refit the electric bicycle. please pay attention and brake in advance to allow longer braking distance in rainy or snowy weather.

Operation Stages:

Start: Press and hold the M button on the left handlebar controls.

Motor On/Pedal Assist
Start pedalling and the electric bicycle will drive forward normally. If you stop pedalling, the electric motor will stop working, but it will still drive forward a short distance because of inertia. You can adjust the level of electrical assistance by toggling the up and down arrows. There are 5 levels of electrical assistance, level 5 being the highest.

B: Throttle only
You can use the thumb throttle only and the bicycle will move without you having to pedal. Click the M button on the handlebar control to turn on the system, with your right thumb press down the throttle, the further you push the throttle the faster it accelerates. To stop or reduce the speed release the throttle and apply the brakes the electric motor will stop working, but it will still drive forward a short distance because of inertia.

Note: A: For your safety concern, please hold the grip tightly with both hands while riding, and please brake in a timely manner when necessary.
B: This bicycle has the function of brake power cut. The brakes will cut off the motor power to ensure safety of riding. Always check your brakes and cables before riding.

Charging Methods and Steps

1. Always charge the battery fully for the first time. When the battery level is low plug it to charge it, use only the original charger provided with the battery.
   

2. Insert the charging pin of the charger into the battery charging plug; pay attention to the direction of the pins, do not insert any other foreign objects or dismantle

3. Connect the power plug of charger into a household AC power outlet. Please do not insert the plug into the AC around water or with wet hands, avoid causing electric shock hazards.

4. Please check the charger indicator. When the LED indicator on the charger is red, it indicates the battery is charging, when the indicator is green, it indicates charging completed.

5. After charging completes, please pull out the charger power plug from the household AC and disconnect the plug from the battery

Attention:

1. Make sure the charger is the original charger.
2. All charging plugs must be inserted tightly.
3. The average charging time of the whole battery pack is 5 hours, please operate in strict accordance with above instructions and keep charger away from children.
4. Please do not charge under the rain or in wet environments.

Battery mounting and removal

I. installing the Battery
Your EMOJO bike comes with the battery installed and integrated into the main frame. You will seldom need to remove the battery, but shall you need to remove it for replacement or to perform a deeper cleaning on your eBike you can easily remove it:

Park the electric bicycle, unlock the battery switch until the key cylinder in the battery front section is free, gently hold the battery from the front section and pull it out. To install the battery, insert it from the bottom section first, then lower it on the front making sure the contact sockets line up, give it a gentle push to lock it into position, lock your battery with the key.

Note: While installing and removing, do not use extreme force to avoid damaging the battery pack and other components.

Front wheel installation

Read the instructions carefully to identify and understand the components of the electric bicycle such as pedal, seat post etc. and the name of relevant spare parts. When specialized servicing of bike is required, please go to an authorized repair shop or store or another trusted bike professional.

1. Assembly of the front wheel unit: Identify the nuts and the lock washers necessary for the front axle assembly.
   Identify the hardware necessary to assemble the front wheel unit onto the front fork (Fig. A). Insert the axle thru the fork starting from the right side (Fig. B opposite to the disc brake), add the washers and nuts on the left side and tighten the nut. Attention: when assembling, make sure the disc brake and the brake caliper are on the same side (left side), the disc brake must slide into the gap between the two brake pads of the disc brake caliper, make sure the wheel turns freely and does not rub against the brake pads when the front brake is not been pressed.
   

2. Front wheel quick release: You can easily remove the front wheel of your bicycle to facilitate transportation or storage, use the quick release lever to loosen the front wheel and remove.
   IMPORTANT: Always make sure your quick release lever is fully tight once putting the wheel back on and before riding.

3. Adjustment of Saddle: Adjust the saddle to the proper height. Using the socket hand wrench, lock the fixed screws on the seat post and clamp tightly. Please note that when adjusting the height of the standpipe and seat post, it has to keep the inserting depth above the safety line.

Disc Brakes

Your electric bike is equipped with disc brakes for maximum reliability. Applying hand pressure to the brake levers will engage the brake pads against the brake rotor, creating friction and slowing down the wheel. The more hand pressure applied to the brake lever, the faster the bike will come to a stop. Check the front disc handle gap by depressing the brake lever about 10 times to check that everything is operating correctly (Fig. 1) If necessary you can adjust the brake by turning the dial on cable (shown with a red arrow). Your front wheel must spin free at all times without any friction from the brake when not applied.

The rear brake should always be applied before or along with the front brake. Applying only the front brake to slow or stop at high speeds may result in the rider being ejected from the saddle and continuing forward over the handlebars. It is best to apply even pressure to both brake levers when slowing or stopping.

Bicycles equipped with disc brakes will occasionally make a slight scraping noise when the wheels are turning without the brakes being applied. This is normal.

Make sure that the brake lever does not contact the handlebar when full hand pressure is applied (b) The contact point should feel firm and solid. If the lever travels all the way to the handlebar or feels spongy, they may require service by a qualified bicycle technician.
If the brakes are still not operating correctly, they may require further adjustment by an experienced bicycle mechanic.

WARNING:

• Disc brake rotors become hot during use. Do not touch or come in contact with the disc rotor shortly after use.
• Wet weather will require a longer distance to stop. Brake earlier and avoid sudden stops when riding in wet conditions.

New Brakes Bed-in Procedure
New brakes will require a “bed-in” procedure prior to your first ride which will ensure the most consistent and powerful braking feel. Find a safe riding area that will allow for moderate speed. Remain seated during the entire procedure for optimal results.

Important Note: Do not lock up the wheels at any point during the bed-in procedure. Accelerate the bike to a moderate speed, then firmly squeeze the brake levers until you are at walking speed. Repeat this process about twenty times.

Accelerate the bike to a faster speed, then firmly squeeze the brake levers until you are at walking speed. Repeat this process about ten times.

Allow the brakes to cool down before your first ride.

4. Pedal Installation and Adjustment: Take out pedals from the accessory box, install one of the pedals (pedals are marked with the letters “L” and “R” to indicate the side they
belong to). When installing the pedals, insert the wrench stuck on the flat end of pedal axial head, and twist into the crank in clockwise direction.

5. Check and Adjustment of Tire Pressure Keep proper air pressure, the space between tire and ground contact is about 10 centimetres long when riding on the electric bicycle.

6. Brake Adjustment
A. When brake lever reaches 1/3 of unstressed state, the power will be cut out completely, when it is at 1/2, bike can brake completely.
B. The distance between brake pad of front wheel and rim should not be more than 2mm, when the brake pads wear down, timely adjustment is possible, after adjustment, the brake pad should not interfere with other spare parts. When a worn brake pad reaches 1/2 of its thickness, it must be replaced.

7. Adjustment of Power Assisting Hall Sensor

A: Turn the bike upside down, have it rest on the floor.
I: The distance between the sensor and the disk shall be 3-5 millimetres Installing the sensor on the side of chain ring, when forwarding the chain ring, the power assistance is effective.

8. The Adjustment of Chain Tension The over relaxation of the check and adjust regularly. The chain would cause chain failing thus threatening safety or damaging the motor. It is suggested to adjustment requirements: in case of single constant speed, when fixed gear, press the chain with hand, the range of the tension is within 10mm from horizontal line.

Electric Bike FAQs

Q. How long does it take to fully charge the battery?
A. Depends on the state of discharge but around 4-5 hours if completely discharged.

Q. What are the running costs for an EMOJO electric bike?
A. You will have no worries about rising fuel prices at the pumps. All our electrically powered vehicles use household electricity. The average cost per full charge is about 10 cents per charge. If you charge the battery every single day for a year, it would cost you about $35 per year.

Q. Can I ride up hills and against strong headwinds on my electric bike?
A. Yes. One of the main advantages of cycling on an electric bicycle is that it literally flattens hills and increases your average speed when tackling inclines and headwinds. If you provide a reasonable amount of effort, you should be able to tackle anything from a 1 in 10 (10%) gradient up to a 1in 7 (14%) gradient. Pedalling along with the motor is strongly advised to avoid overheating of the motor and to extend the battery life.

Q. Do I need a driver’s license, insurance or registration?
A. No, you don’t. According to Federal law, electric bikes that are under 750 watts are classified as bicycles. For all intents and purposes, it’s simply a bicycle that requires very little pedalling to travel 20 MPH (32 Km/H), saving you time and hassle. Check your local state laws for requirements.

Q. Do I need to pedal an electric bike?
A. No, but it helps to prolong battery life. The motor on our bikes is both throttle and pedal assist controlled, allowing you to decide how much power you desire. Have you ever tried to cycle when speeding downhill on your normal bicycle? It’s just like that. The motor is propelling you faster than you’re cycling so there is pretty much no resistance, it’s merely a formality!

Q. What happens if I get a flat tire?
A. The tires on our bikes are the same as conventional bicycles. Simply replace the tube with a tube of the right size and inflate it. No special tires or parts will be needed.

Q. What happens when I use the brakes under powered assistance?
A. All our bikes are equipped with brake levers that have a built-in safety switch that automatically cuts off the motor power under normal braking conditions. This not only ensures a safe un-powered stopping feature, but also protects the motor under braking conditions so that it isn’t working against the brakes.

Q. How far will the bike take me?
A. This all depends on a few factors. Cycling with pedal assist along a straight road under normal conditions, the standard battery should last about 30 miles (50 kilometres). Cycling up steep hills will obviously take more energy out of the battery and factors such as road surface, wind resistance, weight of the rider and tire pressure will affect your range. The range with throttle only lasts about 20 miles (35 km)

Q. How do I know when the battery is low?
A. The bicycles have easily visible indicators located on the meters that show the amount of juice left. If it is getting low and you don’t think you will make it to your destination, you can switch off your motor and keep it just for the difficult bits.

Q. Do I have to wait for the battery to empty before I charge it?
A. No. The batteries we use are Lithium-ion batteries which do not suffer from ‘memory effect’. This means that there is no need to discharge a battery completely before you recharge it again. You can partially recharge the battery at any time without reducing its voltage or lifespan. We recommend recharging the battery after every use, regardless of how far you rode.

Q. Can I put a child’s trailer?
A. Yes, you can certainly add a trailer to your bike. We suggest contacting your local dealer for approved trailers.

Q. Can I put the electric bike on a bike rack?
A. Yes, just make sure that the bike rack can hold the weight of the bike. We advise taking the battery off to make it easier to lift and to keep the battery safe.
