If your Mokwheel E-Bike is not working, check the cables to make sure they did not come loose or unplugged. Simply unwrap the black spiral wire covering until the Quick Disconnect fitting is exposed, unplug and re-plug the Quick Disconnect fitting(s).

Troubleshooting Guide

2. Brake error
Check whether the brake cable is loose or dam- aged. If there is no damage, replace the brake or brake lever and cable.
3. Power-assist sensor error
Step one: Check whether the sensor cable is loose or falling off. If not, it may be due to the damage of the power-assist sensor. Step two: Remove and replace the power-assist sensor.
4. Walk Cruise mode error
Shut down and restart the Ebike (if this issue cannot be solved, consider replacing the controller).
5. Real-time mode error
Shut down and restart the Ebike (if this issue cannot be solved, consider replacing the controller).
6. Low voltage error
Step one: Remove the battery to check if there is enough battery power. Step two: Charge the battery. Step three: If the issue is not solved after completing the previous two steps, it may indicate motor damage. Replace the motor.
7. Motor error
Check whether the motor connecting cable is loose, falling off, or plugged in backward (if not, it may indicate motor damage, consider replacing the motor).
8. Twist throttle error
Check whether the connecting cable is loose or falling off (if not, it may indicate twist throttle damage, replace the twist throttle).
9. Controller error
10. Connection receiving error
11. Connection sending error
12. BMS connection error
Step one: Check whether the connecting cable is loose or falling off.
Step two: Shut down and restart the Ebike (if the issue cannot be solved after completing the previous two steps, consider replacing the controller).
13. Headlight error
Step one: Check if the connecting cable is loose or falling off.
Step two: Press the headlight key again. If the headlight cannot be turned on, it is confirmed that the headlight is damaged and a replacement is needed.

Tools Needed:

Needle nose pliers
Hex keys
Replacement brake pads

Step 1: Brake Pad Removal

1. Get the bike ready for maintenance. First turn off the bike to remove the battery.
2. Locate the brake pads. The brake pads are located inside the brake caliper on each wheel (see photos for reference)
3. Remove the brake caliper first. Use a hex key to remove the two brake caliper bolts from the bike frame(Warning: Be careful not to lose or misplace the washers inside of the brake caliper bolts.)

4. Carefully straighten the retention pin using needle-nose pliers to remove the brake caliper by pushing it upwards. 

Step 2: Brake Pad Installation

1. Install the new brake pads into the brake caliper. Assemble the brake pads in the same configuration as the old pads. The friction material should be facing each other. Make sure the top hole of each pad is aligned with the retention pinhole. Slide the new brakes into the caliper to complete installation.

Tip: The best way to maintain your brakes is to use both brakes together and engage the rear brake first to avoid excessive strain on the front wheel and fork.

The brake adjustment will involve:
• • Checking the wheel to make sure it is fully seated in the frame dropouts. An improperly seated wheel can cause the brake disc to rub against the brake pads and generate noise.
• • Checking that the brake disc is straight and in good condition. Damaged or dirty brake discs can result in reduced brake performance or noise.
• • Centering the brake caliper by adjusting the positioning so the inner pad, a stationary component of the brake caliper, is close and parallel to the brake discs. A brake pad or brake caliper that is not properly positioned can lead to reduced brake performance or noise.
• • Adjusting the brake cable tension and checking the brake lever. These final adjustments will help ensure the brakes were adjusted correctly.

Get the bike ready for maintenance. Remove the battery and press and hold the power button for 10 seconds to discharge the remaining power.
1. Remove the left crank first. Unscrew the bolt with a hex key and insert a crank puller to remove the crank.

PAS Sensor Troubleshooting

Crank should be removed (refer to crank removal guide)
1. Locate the PAS sensor behind the left pedal to check if it’s loose.
2. If the PAS sensor is not loose, trace the cable coming out of the PAS sensor to the connector.
3. Unplug the PAS sensor connector and take out the controller.
4. Location the connecting cable between the controller and PAS sensor to check if it’s loose.
5. Inspect the inside of the connector for dirt, damage, or moisture. If there is dirt, damage, or moisture inside the connector, the sensor may need to be replaced.

PAS Sensor Replacement

The wiring harness connects various electrical components on your bike. If instructed by MokWheel Product Support to perform a wiring harness connector check, follow the steps below to check that the connector is plugged in and in working order.

Tools Needed:
Hex keys

Get the bike ready for maintenance. Remove the battery and press and hold the power button for 10 seconds to discharge the remaining power.
Flip over the bike and rest on the handlebars in order to prevent damage to the LCD display while performing maintenance.

1. Locate and take out the controller.
2. Check if the connecting cable is loose, unplug and reconnect again. The connector must be unplugged by pulling both sides straight apart, without twisting. If it looks normal on the inside, align the internal notch and pins and press directly together, without twisting.

Tools needed:
Pliers
Hex keys
1. To remove the handlebar, loosen the handle grip bolts first.

Stem Removal

Tools Needed:

Hex key

Step 1: LCD Display Removal

1. Getting the bike ready for maintenance. Remove the battery and press and hold the power button for 10 seconds to discharge the remaining power.
2. Unplug the LCD Display connector. Follow the cable from the back of the LCD Display to the wiring harness.

1. To remove the brake levers, first loosen the brake cables from the brake caliper.

1. Remove the wheels first before removing the brake discs (see wheel replacement guide for help).
2. Use a hex key to remove the five bolts securing the disc onto the wheel and simply lift the disc to remove.

Kickstand Removal

1. Remove the bolts for the kickstand that is attached onto the chainstay.

Front Wheel Removal

(This is done similar to when you first installed the wheel)
1. Flip over the bike and stabilize the bike on the handlebar 2. Remove the two front wheel bolts at each side with a wrench. Locate and loosen front wheel bolts and remove them with a wrench.
3. Remove the front wheel. Lift the front wheel gently off the front fork

Back Wheel Removal

1. Flip the bike around and remove the kickstand first(see above), and then unscrew the bolts attaching the back wheel.

1. To remove the shifter, snip off the tip of the shifter cable and release it from the derailleur.

1. Cut the zip ties to release the connecting wire and unplug by pulling apart. Then unscrew the bolts behind the rearlight to remove.

1. To remove the throttle, the handle grips have to be removed first(see handle grip replacement guide).
2. Loosen the bolt and disconnect the wire connecting to the throttle. Pull the throttle off the handlebar to remove.

1. Push the derailleur forward to release the chain from the crank.

Installation Guide

1. To install, attach the derailleur to the bike first.

1. Unscrew the headlight bolts from the front fender and disconnect the wire to remove the headlight.
