Burchda RX10 Electric Bicycle

Precautions

Please carefully check whether all parts are in good condition before use. If there is any problem, please contact the dealer in time.

Abide by the city traffic laws and regulations when using.

Slow down when encountering rain, snow, and slippery roads. Increase braking distance when braking, and avoid traveling as much as possible to ensure safety.

Do not disassemble parts without authorization. If you need to replace them, please purchase standard parts from distributors.

Wading is prohibited during riding or when riding in rainy days. When accumulated water floods the lowest position of the motor hub, it will cause line failure.

Do not contact the metal point of the battery, otherwise it will produce a large short-circuit current and cause an accident and fire. Please pay attention!

Wear a helmet when riding an electric bicycle, and carry articles according to the law.

Do not park electric bicycles in the foyer, stairs, walkways, and safety exits of buildings.

Due to the continuous improvement of products in technology, there may be different things between the physical objects and the instructions. Please take the physical object as the standard.

Special Tips:

Do not park electric bicycles in the foyer, stairs, walkways, and safety exits of buildings.

Electric bicycles should not be charged and parked in residential buildings. When charging, they should stay away from combustibles and flammable materials and avoid charging for a long time. Waste batteries cannot be disassembled without authorization.

Riding Precautions

Accelerate slowly when starting, and help with pedals when climbing, which can prolong the service life of batteries and motors.

The bicycle controller is equipped with an overload protection function, which will automatically cut off the power supply when overload occurs. When it returns to normal, the power supply of the electric bicycle will be automatically turned on.

The maximum load capacity of this bicycle is 180kg (including the weight of the rider). Do not overload driving. When driving on complex roads, try to ride and turn on the shock absorption function.

Parking Precautions

When implementing, the power switch should be turned off to prevent accidents caused by sudden start of the bicycle due to unintentional rotation of the speed regulating handle. When parking, turn off the power supply, lock the battery, and remove the key.

For the sake of your driving safety and keeping your bike in the best condition, please maintain it regularly.

Battery Storage

Please store the battery at an ambient temperature of 20~25°C, and do not store the battery in an environment higher than 50°C, otherwise it will lead to irreversible capacity attenuation of the battery.

If the bicycle is not used for a long time (such as winter, summer, or other special circumstances), the battery must be taken out and stored separately, maintained, and charged regularly, otherwise the battery may run out and cause irreversible damage.

The most suitable storage capacity of the battery is 50%. Long-term storage of less than 10% or more than 90% will lead to irreversible capacity attenuation of the battery.

Bicycle Installation

Since 95% of the bicycles have been installed, the rest can be installed directly after receiving.

1. Install handlebar riser.

2. Adjust the nut position.

3. Install the front fork on the front wheel bearing.

4. Tighten the left and right nuts as shown.

5. Install the lights and fenders, and connect the light wires (note that the arrows at both ends of the wiring correspond).

6. Install the fender bracket screws.

7. Connecting the headlight cable (please note that the arrow wiring at both ends corresponds).

8. Take out the pedal with the letters "R" and "L", align it with the crank hole and lock it with a wrench.

Electric Bike Charging

First, connect the charger to the electric bike battery, then connect the other end to the power source.

If you smell a peculiar smell during charging, please stop charging immediately and send it to the maintenance office for maintenance.

When charging, do not touch the battery or charger, and children are strictly forbidden to touch the charger.

Keep the charger or battery away from flammable materials. Do not charge near babies and children. Do not charge in an unattended state for a long time. For the safety of you and your family, it is recommended not to charge in the early morning.

Please do not use other brands of charger charging; the charger is a high-voltage circuit; do not disassemble without authorization.

Electric bicycles are equipped with special batteries, which must be charged by the special charger provided by our company. Before charging, the electric bicycle must be turned off. When charging, the output end of the charger is linked to the electric bicycle, and then the other end of the charger is linked to the power supply for charging. The red indicator of the charger lights up, indicating that charging is underway.

Battery Disassembly and Assembly

1. Twist the key in the direction of the arrow to open the battery lock.

2. Push the battery in the direction of the arrow.

3. Take out the battery like an arrow direction.

Precautions for Battery Use

It takes about 6 hours to charge the battery. When the indicator turns green, it indicates that it is fully charged. Turn off the power connected to the charger first, remove the charger, and try to avoid charging for a long time (avoid more than 12 hours).

When charging, the charger and battery should not be covered with anything to avoid danger caused by overheating. It is recommended to start charging when the battery charge is less than 20%. When parking for a long time, it should be stored at 50% of the power, and must be charged once every other month.

Pattern Description

In pedal assist mode, assist is triggered when the pedal is pressed forward, and is stopped when the pedal is stopped. When you brake, the power assist system will automatically stop, allowing the e-bike to slow down and stop. When the e-bike reaches the maximum speed of the gear you have selected, the power assist will turn itself off.

Mode 1: Electric only

The electric bicycle is driven by electricity.

Mode 2: Electric assist

The key is turned on, and the instrument is turned on. At this time, the electric auxiliary mode will be started, which is driven by manpower and electric power.

Mode 3: Manual power

Riding an electric bicycle, the electric bicycle is driven by manpower.

Motor Description

When the electric bicycle starts, the input current of the drive motor is large, and the motor will have a certain noise to overcome the resistance to reach the speed. It is the friction sound of the current torque and the magnetic force, which is a normal phenomenon. If the starting current of the electric bicycle is increased, all noises will be more obvious. This is a normal phenomenon and will not affect the use of the electric bicycle. (Note: When the electric bicycle starts, it can be accelerated slowly when accelerating. At this time, the starting current will not be too large, and the noise of the driving wheel will be relatively small. At the same time, it will be beneficial to the battery life).

Warning Matters

Warning:

• Do not put the battery into fire. Do not overheat the battery.
• Do not use other brand chargers to charge the battery. Use the specified charger.
• Do not disassemble or modify the battery.
• Do not connect positive and negative electrodes or touch terminals with metal objects.
• Do not subject the charger to shocks, such as dropping. Keep the charger away from water.
• Do not let your skin touch the charger for a long time during charging. May cause skin burns because the temperature of the charger may become 40°C~60°C (104°F~140°F) during external charging.
• Do not cover the charger with objects or place objects on the charger to avoid overheating and fire.
• Please do not turn the pedal when the battery is installed on the bicycle for charging. Avoid winding the power cord on the pedal or crank, which may cause plug damage, electric shock or fire.
