Lectric Controller and Display Settings: User’s Guide
This guide walks you through using the controller and display on Lectric e-bikes (XP, XP Lite, XP Step-Thru, XP 2.0, XP 3.0, and later models). You’ll learn how to navigate menus, adjust pedal assist and throttle settings, change speed limits, diagnose error codes, and find a compatible replacement display. Every section includes a concrete step you can apply to your own bike.
Before You Start
You’ll need the bike battery charged and turned on, the display powered up, and a clear view of the screen. If the display is blank or flickering, check the cable connection between the display and the controller (the plug is usually inside the stem or near the head tube). Unplug and reseat it firmly before proceeding.
What you should have on hand:
- Bike owner’s manual (or a note of your current parameter values if you’ve changed them before)
- Small Phillips screwdriver (if you need to open the display cable cover)
- Phone camera (to snap a photo of the original settings before changing anything)
If the display shows an error code (like `E01` or `E05`) before you even touch a button, skip to the diagnostic section below first – that fault may need fixing before any menu changes will stick.
Navigating the Display Menus
Most Lectric displays use three or four buttons: Power (or Mode), Up, and Down. A fourth Mode button appears on some models. The menu system is accessed differently depending on the firmware, but the most common method for XP 2.0 and 3.0 bikes is holding Up and Down together for 3 seconds while the bike is off.
Ordered Action Sequence (XP 2.0 / 3.0)
1. Turn the bike off using the battery or display power button.
2. Press and hold both Up and Down buttons simultaneously. After about 3 seconds the screen will flicker and show `P01`.
3. Release the buttons. You are now in the parameter menu.
4. Navigate parameters with Up/Down. Only a few parameters (`P01` through `P08`) are active on most units.
5. Select a parameter by pressing Power. The current value will flash.
6. Change the value with Up/Down.
7. Confirm by pressing Power again. The display jumps to the next parameter.
8. Exit by holding Power for 5 seconds or turning the battery off.
Branch: what if the screen stays blank after step 2?
Try the alternative method: turn the bike on first, then hold Up and Down. If that fails, the display may be in a “locked” state. Hold Down + Power for 8 seconds to unlock. Still nothing? Disconnect the battery for 30 seconds, reconnect, and try again. If the display remains unresponsive, the controller or display may have a hardware fault – see the replacement section later.
Key Parameters Worth Adjusting
| Parameter | What It Controls | Typical Default | Notes |
|---|---|---|---|
| P01 | Wheel diameter (inches) | 20 (most XP) or 26 (some lite models) | Set to the actual tire diameter printed on the sidewall. Wrong size throws off speed and odometer. |
| P02 | Speed limit (km/h) | 32 (≈20 mph) | Raising it to 45 (≈28 mph) unlocks Class 3 mode. Local laws may restrict this. |
| P05 | PAS mode / throttle enable | 0 or 1 | 0 = pedal assist + throttle; 1 = throttle always on; some models have 4 = no throttle. |
| P06 | Throttle start mode | 0 | 0 = throttle works at any speed; 1 = only after you start pedaling. |
| P08 | Restore factory defaults | 0 | Set to 1 and power cycle to reset everything. |
Verification step after changing any parameter:
Exit settings, then ride a short test loop (100 yards) at low speed. Check that the speed reads correctly (compare to a phone GPS app) and that the PAS levels feel consistent. If the bike behaves unexpectedly (e.g., throttle doesn’t respond or speed jumps), re-enter settings and double-check the parameter you changed. You can always set P08 to 1 to start fresh.
Adjusting Pedal Assist and Throttle Settings
From the main screen, press Up or Down to change the PAS level (0–5). Level 0 gives no motor help; level 5 delivers full power (up to 750W on most Lectric models). The throttle is typically variable – twist it partway for partial power – but some early XP Lite units have an on/off throttle that gives full power at any twist.
If you want to disable the throttle completely (for a youth rider or off-road use), set parameter P05 to 04. After that, only the pedal sensor will activate the motor. Note that this may affect the bike’s legal classification – check your local laws before riding on public paths.
Example range trade-off (500 Wh battery, 20‑mile commute with moderate hills):
- PAS level 2: 30–35 miles range
- PAS level 5: 12–18 miles range
Running at level 5 constantly also heats the motor faster. If you ride mostly flat terrain, level 2–3 gives a good balance of help and efficiency.
Realistic Failure Mode: Throttle Stays On After Release
Symptom: The bike continues to accelerate after you let go of the throttle.
Likely cause: The throttle sensor has drifted out of calibration, or the return spring is stuck (dirt or salt buildup).
Safer next move:
1. Immediately cut power using the display power button or by unplugging the battery.
2. Inspect the throttle grip for visible debris or binding. Spray a small amount of silicone lubricant where the grip meets the handlebar.
3. If that doesn’t free it, go into settings and set P06 to 1 (throttle only works after pedaling). This acts as a safety interlock – you’ll need to pedal first for the throttle to respond.
4. If the problem persists, replace the throttle assembly (about $15–20). Do not ride with a sticking throttle – it can cause loss of control.
Speed Limits and Legal Compliance
Lectric ships most bikes as Class 2 (20 mph top speed, throttle can be used at any time). You can raise the speed limit to Class 3 (28 mph) using the display settings, but that may make the bike illegal on bike paths that restrict Class 3 use.
To unlock 28 mph (common method):
1. With the bike off, hold Up and Down together.
2. While holding, turn the battery on. Wait for a code prompt (usually `1234` or `0000`).
3. Enter the unlock code using Up/Down to change digits, Power to confirm. Default codes vary by model year – check your manual or contact Lectric support.
4. After unlocking, set P02 to 45 (km/h). The display will now show speeds up to 28 mph.
What happens after you unlock Class 3?
The speedometer will read accurately up to 28 mph, but range drops significantly – expect 18–22 miles on a 500 Wh battery at sustained top speed. The motor also runs hotter; prolonged full-throttle climbs can trigger thermal cutout (motor stops until it cools). If you only occasionally need 28 mph, consider leaving it at 20 mph for daily commuting and using the unlock only for long, flat open roads.
Diagnostic and Error Codes
If the display shows an error like `E01`, `E02`, etc., the controller has identified a fault. Here’s what each code means and the first action to take:
| Code | Meaning | Quick Check | Next Step |
|---|---|---|---|
| E01 | Display-controller communication lost | Reseat display cable at both ends | If code returns, replace display or controller |
| E02 | Brake sensor error | Squeeze each brake lever to see if code clears; check magnet alignment | Replace brake sensor if magnet gap > 5 mm |
| E03 | Throttle error (stuck open) | Unplug throttle; if code disappears, replace throttle | If code stays with throttle unplugged, controller fault |
| E04 | Motor phase wire short | Inspect cable near axle and controller connector | Look for pinched or frayed wires; replace if damaged |
| E05 | Over-current or motor stall | Turn bike off, let it cool 15 minutes | If code returns on flat ground, motor may be failing |
Verification step after clearing a code:
Turn the bike off, wait 10 seconds, then turn it back on. If the error does not reappear during a short test ride (500 feet at low speed), the issue is likely intermittent. If it returns immediately, the hardware problem is persistent and needs repair.
Replacement Displays: What to Look For
If your original display is dead (no power, frozen screen, physical damage), you can replace it. All Lectric XP-series bikes use a 5-pin M5 connector and speak the No. 2 protocol for 36V/48V systems. The following table shows products from the available data – note that only the first entry is an e-bike display; the other two are unrelated items.
| Product | Price | Brand | Rating | Best For |
|---|---|---|---|---|

Top Pick: Bike Display LCD 5 Pin M5 Control Panel Bike Screen (No. 2 Protocol)
This universal display explicitly supports the No. 2 protocol used by Lectric controllers and works across 24V–60V systems, making it a safe swap for most XP models. Before ordering, confirm your controller’s voltage and connector pinout by checking the manual or emailing Lectric support with your model year.
Frequently Asked Questions
How do I reset the display to factory settings?
Enter the settings menu (hold Up+Down), go to P08, set it to 1, then turn the bike off and on. This restores all parameters to their original defaults.
My display shows 0 mph even when moving – why?
The wheel speed sensor wire is likely disconnected or the spoke magnet is out of alignment. Check the sensor gap (should be 2–5 mm from the magnet) and make sure the magnet passes cleanly in front of the sensor with each wheel rotation.
Can I use a display from another brand on my Lectric?
Only if it uses the same 5-pin M5 connector and No. 2 protocol. Many King-Meter or Bafang displays also support this protocol, but compatibility is not guaranteed. Always verify with the seller before buying.
The display turns on but buttons don’t work – what now?
Try unplugging the display cable and plugging it back in to reset the connection. If the buttons remain unresponsive, the display’s membrane or internal circuit is damaged – replace the display.
