Introduction: This article covers how to replace the LCD screen, bracket, and keypad. The LCD is fully sealed and permanently connected to the keypad. It is used to turn your Voltbike on/off, control lights, set the pedal assist levels, display speed/distance, and access basic and password protected settings. The LCD/ keypad unit may need to be replaced due to malfunction or physical damage.

1. Main Power discharge: Remove the battery and hold the keypad power button down, as if you were turning the system on. The LCD should briefly light up using the residual charge that may be present in the system. This will reduce the likelihood of causing electrical damage while any part of the system is being serviced.

2. Disconnect the LCD cable: Follow the cable from the back of the screen, and disconnect it from the main wiring harness. Ensure the new replacement LCD has the correct /quick connector by checking the orientation and number of pins. Note the alignment arrows for pressing the quick connector together.

 

3. Remove the Keypad: Remove the 3mm bolt (2.5mm hex tool) Caution: the nut may drop from the bottom of the clamp when the bolt is removed. Carefully remove the keypad clamp off the handlebar.

 

4. Remove the display bracket clamp: Loosen the two 4mm bolts on both sides (3mm hex tool) Caution: nut may drop from the bottom of the clamp, when the bolt is removed



Spread the clamp gently, and guide it over the handlebar.

 

Note:To swap a broken or damaged mounting bracket only, remove the two 4mm bolts attaching the bracket to the back of the display( 3mm hex tool) . Reinstall the LCD screen upright on the new bracket. 


5. Install the display bracket with LCD on the handlebar Spread display clamps, and carefully place on the handlebar (no rubber shims are needed for 31.8mm diameter handlebars) Center and tilt the display for optimal viewing position. Install the 4mm bolts and nyloc nuts (3mm hex tool). Tighten till the bracket is secure but can still rotate.

 

6. Install the keypad on the handlebar. Insert and tighten the 2.5mm bolt (2mm hex tool) and nyloc nut for the keypad clamp. Tighten till the clamp is secure but can still rotate.

 

7. Plug display cable into the wiring harness. CRITICAL! Check the alignment arrows before carefully pressing the quick connector together. Ensure proper orientation, as the pins can be damaged if inserted incorrectly.

 

8. Power On and Test:
Reinstall the battery and hold down the power button to turn the system on. Watch LCD for backlight function, and that all display options, pedal-assist levels, front/rear lights,etc. are working correctly. Note: The LCD module stores the settings for wheel size, speed display units and other operational parameters. You may need to reconfigure your settings after changing an LCD to ensure proper performance of your ebike. To configure the settings, please refer to the instruction booklet included with the replacement LCD.
