This document is the Owner's Manual for the KHS Movo 1.0E E-BIKE. It provides instructions for battery handling, LCD operation, and troubleshooting.
Battery Dismounting and Mounting Instructions:
For safety and shipping regulations, the lithium-ion battery is not fully charged and is in a hibernate state upon delivery. It is crucial to charge the battery before its very first use.
To dismount the battery:
- Insert the key into the battery keyway.
- Turn the key counterclockwise to unlock the battery.
- While holding the end of the rear rack with one hand and the end of the battery with the other, pull the battery backward away from the bicycle.
To mount the battery:
- Ensure the key is in the unlock position.
- With one hand holding the end of the battery and the other hand holding the end of the rear rack, slide and push the battery all the way into the battery rack.
- Lock the battery by key. Failure to lock the battery can result in inconsistent power.
The key is solely for locking and unlocking the battery. When in the "locked" position, remove the key from the keyway and keep it with the bike to prevent loss. It is recommended to keep the spare key with the charger.
Charging the Battery:
- Verify that the battery voltage is compatible with the charger.
- 36V batteries must be charged with a 36V (42V) charger.
- 48V batteries must be charged with a 48V (54V) charger.
- Open the soft cover of the battery charging port.
- Insert the charging connector into the battery charging port.
- Connect the charger power plug to a 100V/240V AC outlet. The charger LED indicator will turn GREEN.
- The charger LED indicator will then turn RED, indicating charging is in progress.
- Once the charger LED indicator turns GREEN again, the charging process is complete. Disconnect the charger connector from the battery and store the charger for future use.
Charger LED Indicator:
- Red light: Indicates charging.
- Green light: Indicates fully charged.
If the LED indicator remains Red after 8 hours of charging, it suggests an abnormal charging condition. Stop charging immediately and report the issue to the supplier for service.
Battery Power Indicator:
Push the soft button to activate the capacity meter.
- Flashing red light: Indicates no power or insufficient power, requiring a charge.
- LED green bars indication:
- 3 green lights = full energy capacity
- 2 green lights = mid energy capacity
- 1 green light = low energy capacity
- 1 steady red light = few energy left
It is recommended to always charge the battery after every ride.
Battery Storage:
- If the bike is used in or after rainy weather, remove the battery and wipe it dry.
- When the battery is not in use for an extended period or after charging, store it without plugging it into the bike.
- Check the battery energy status and charge it every three months.
Cautions when Charging:
- It is strictly forbidden to charge the battery with an uncertified charger.
- Avoid direct sunlight. Charge in a dry and well-ventilated environment.
- For optimal charging efficiency, charge within a temperature range of 32°F to 104°F (0°C to 40°C).
- Battery performance naturally deteriorates over time, whether used or not (known as "calendar fade"), and with usage (known as "cycle fade"). Following these instructions can effectively extend battery life and performance.
Model vs. Battery vs. Charger Compatibility:
- Easy 24: 36V battery, 36(42)V charger
- Envoy 200: 48V battery, 48(54)V charger
- Movo 1.0E: 48V battery, 48(54)V charger
- Extended 2.0: 48V battery, 48(54)V charger
LCD Operation (One Switch Version):
Switch On or Off:
- On: Press the "M" key on the LCD for 1 second to turn on.
- Off: Press the "M" key on the LCD for 2 seconds to shut off.
Automatic Shutdown System:
To conserve power, the MOVO1.0E will automatically shut off if it remains idle for 10 minutes.
LCD Dashboard Content Description:
Power Output and Battery Level Indicators Section:
- POWER output indicator: Each cell represents 2A (current) of output power.
- BATTERY level indicator:
- 100~90%
- 90~80%
- 80~60%
- 60~40%
- 40~20%
- 20~10%
- 10% Flashing
When the battery is empty, all six cells will be blank, and a red light will flash. The motor will stop, and ERROR code (1) will be displayed, indicating "Please charge or change the battery... ASAP."
Power Assistance Level Indicator Section:
- Push (+): To increase power assistance level (0, 1, 2, 3, 4, 5).
- Push (-): To decrease power assistance level (5, 4, 3, 2, 1, 0).
Speed Indicator Section: MPH vs. KM/H:
- Push "M" and "(+)" simultaneously for 2 seconds to toggle the speed unit between Miles Per Hour (MPH) and Kilometers Per Hour (KM/H).
Pushing the "M" button briefly will cycle through the following functions:
- Cycle through information automatically (Σ, KM, MAX).
- Odometer: Recorded by the system since the manual reset.
- Time: Time since the system was turned on.
- Distance: Distance traveled since the system was turned on.
- Max Speed: Maximum speed since the system was turned on.
Notes:
- NOTE 1: Distance and speed units depend on the selected MPH or KM/H unit in the Speed Indicator section.
- NOTE 2: To clear all information except the odometer, push "M" and "(-)" together for 2 seconds.
- NOTE 3: To clear all information including the odometer, push "M" and "(+)" together for 10 seconds.
Throttle:
Push the throttle lever, and the bike will move without pedaling.
Walking Mode (3.8 MPH / 6 KM/H):
- Press "(-)" on the control panel button for 2 seconds to activate walking mode.
- Releasing the button will immediately stop walking mode.
Walking mode causes the motor to run up to 3.8 MPH (6 KM/H). It is designed to assist when pushing the bike uphill or when a slow pace is desired. When engaged, the power assistance indicator will display "AUTO 6".
LCD Backlight and Front & Rear Lights:
- On: Press and hold "(+)" on the control panel for 1.5 seconds to turn on.
- Off: Press and hold "(+)" on the control panel for 1.5 seconds to turn off.
NOTE: The bicycle battery must be "ON" for the bicycle lights to function.
Troubleshooting (Error Codes):
If an error code appears, it indicates an issue. The numeric codes are defined as follows:
-
Error Code 1: Voltage too low
- Definition: 48V system is under 42V; 36V system is under 32V.
- Solution(s): Charge the battery or replace it.
-
Error Code 2: Brake is stuck or shorted
- Definition: The brake mechanism is jammed or the wiring is short-circuited.
- Solution(s):
- Check the brake to ensure it's not stuck.
- Unplug the brake wire to see if the error message disappears. If it does, the wire may be shorted.
-
Error Code 4: Crank sensor no signal or no phase
- Definition: The crank sensor is not sending a signal or there's a phase issue. This code may appear at power-on with power assistance level (0) and should disappear automatically after 30 seconds or when pedaling starts.
- Solution(s): If the code persists within the first 30 seconds of pedaling, it indicates no flash signal from the crank sensor. The sensor needs to be replaced.
-
Error Code 5: Motor overload, reduce motor output
- Definition: The motor is experiencing an overload.
- Solution(s):
- Shut down and restart the system.
- Set to maximum assistance level.
- The motor may require repair.
-
Error Code 6: Controller temperature exceeds 158°F (70°C)
- Definition: The controller's temperature is too high.
- Solution(s): Power off and wait until the temperature decreases back to normal (about 10 minutes).
-
Error Code 8: Motor Hall is abnormal
- Definition: An issue with the motor's Hall sensor.
- Solution(s):
- Check if the connection between the motor and controller is loose or broken.
- The motor may require repair.
-
Error Code 9: Motor overcurrent
- Definition: The motor is drawing excessive current.
- Solution(s):
- Shut down and restart the system.
- The motor may require repair.
-
Error Code 14: Wheel diameter Sensor abnormal
- Definition: An issue with the wheel diameter sensor.
