Mokwheel Controller and Display Settings: User’s Guide
The display settings on a Mokwheel e-bike are accessed through the handlebar-mounted LCD screen and control pad. You can adjust speed limits, wheel size, battery voltage, and other parameters using the P-settings menu (often labeled P01–P99). This guide walks you through the most useful settings and how to change them without guessing.
Accessing the Display Menu
Turn on the bike by pressing and holding the MODE button (or POWER button, depending on model) for about 2 seconds. Once the screen lights up, press and hold both the UP and DOWN arrows together for 3–5 seconds. The display will show “P01” or a similar code – you are now in the parameter menu.
- Scroll through parameters with UP or DOWN.
- Adjust a value by pressing MODE to select, then UP/DOWN to change.
- Exit by holding MODE for a few seconds or turning off the display.
If the display does not enter menu mode, check that the battery is fully connected and the controller has power. Some Mokwheel models require pressing MODE + UP instead of UP + DOWN – try that combination if the standard method fails. If neither combination works, your display may be a different revision; consult the owner’s manual for the exact key sequence.
Common Adjustable Settings (P‑Parameters)
Different Mokwheel models use slightly different parameter tables, but the most frequently adjusted ones are listed below. Verify your exact values against your owner’s manual if available.
Speed Limit (P08 or P14)
This controls the maximum motor speed allowed by the controller. On many Mokwheel models, setting this to 100 removes the speed cap. Lower values (e.g., 60) enforce a 20 mph limit.
- How to adjust: Enter P08 (or P14), press MODE, set the number between 0 and 100. Press MODE again to lock.
- Rider outcome: A higher number allows higher assist speeds. Class 2 bikes are capped at 20 mph, Class 3 at 28 mph. Check local regulations before raising the limit.
- Real-world mistake: Setting the speed limit to 100 on a bike with a 20 mph motor (e.g., a typical Class 2) won’t actually make it go faster – the motor’s physical limit remains. If you try to force a higher speed by increasing the limit on a motor that can’t support it, you may trigger an “E07” error or cause the controller to overheat. Always verify your motor’s rated RPM before expecting a speed gain. Additionally, raising the speed limit increases power draw at high speeds, which can cut range by 20–30% on longer rides. For dual-battery models like the Mokwheel Obsidian (up to 90 miles of range), the range drop is less severe, but still noticeable.
Wheel Size (P01)
Set this to match your actual wheel diameter in inches. Common values:
| Wheel Size | Setting Value |
|---|---|
| 20” | 20 |
| 26” | 26 |
| 27.5” | 27.5 |
| 29” | 29 |
An incorrect wheel size causes speedometer errors and may affect power delivery. Deeper impact: If you set the wheel size too small, the odometer will accumulate miles faster, potentially voiding a mileage-based warranty. If you set it too large, the speed reading will be lower than actual, which can cause the motor to cut out prematurely because the controller thinks you’re exceeding the speed limit. Measure your tire’s true rolling diameter (including tread depth) rather than relying on the rim size alone. A 27.5-inch tire with a 2.4-inch tread can actually measure 28 inches – account for that.
Battery Voltage (P02 or P05)
Set to match your battery pack voltage (e.g., 36V, 48V, 52V). Using the wrong value can undercharge or damage the battery.
- Warning: If you upgrade to a higher voltage battery, you must update this parameter along with the controller’s low-voltage cutoff (often a separate setting like P03 or P11).
- Consequence of mismatch: Setting the voltage too high (e.g., 52V on a 48V battery) will cause the state-of-charge bars to show full even when the battery is nearly empty, leading to an unexpected cutoff mid-ride. Setting it too low can trigger early low-voltage cutoff, reducing range. If you use a 48V battery but set the parameter to 36V, the controller may try to charge it beyond safe voltage, risking a battery management system shutdown or cell damage.
Password / Lock (P09)
Some Mokwheel displays allow you to set a 4-digit unlock code. Default is usually 0000. To disable the lock, set to 0000 and save. If you forget a custom code, you may need to power-cycle the bike and try 0000 or 1234 – some displays have a hard-coded master override.
Additional Parameters Worth Knowing
- P03 – Low Voltage Protection: Sets the voltage at which the controller cuts power. For a 48V battery, typical values range from 40V to 42V. Lowering this value lets you drain more capacity but risks over-discharging the cells. Stick to the manufacturer’s recommendation.
- P10 – Pedal Assist Sensor Type: Usually set to 1 (magnet-based) or 2 (torque-based). Changing this without a physical sensor swap can disable PAS entirely. Leave it alone unless you know your sensor type.
- P12 – Current Limit: On some controllers, this controls the maximum amp draw. Reducing it can extend battery life but lowers hill-climbing torque. Do not exceed the controller’s rated continuous current (often stamped on the side).
How to Change the Speed Limit – Step‑by‑Step
1. Turn on the display.
2. Press and hold UP + DOWN for ~4 seconds until “P01” appears.
3. Press UP several times until you reach P08 (or P14, depending on your display revision).
4. Press MODE once. The current value will blink.
5. Press UP to increase the value to 100 (or your desired maximum).
6. Press MODE to confirm.
7. Hold MODE for 2 seconds to exit the menu.
Test: Ride the bike – if the throttle cuts off at 20 mph and you want more, repeat steps and set to 100. If the motor cuts off erratically, the controller may have a separate speed sensor adjustment; check the manual.
Failure mode to watch for: After raising the speed limit, if the bike suddenly loses power at low speeds (e.g., under 10 mph), the controller’s internal speed limit may still be active via a different parameter (sometimes P14 on newer models). Switch to that parameter and set it to 100 as well. If the problem persists, the controller board may have a hardware speed cap that cannot be overridden – safely return to stock settings.
Resetting to Factory Defaults
If you’ve changed several parameters and the bike behaves unpredictably, you can often reset the display to factory defaults. On most Mokwheel displays, press and hold MODE + UP + DOWN simultaneously for 8–10 seconds until the screen flashes and restarts. This clears all P‑settings and returns them to the manufacturer’s default values. Write down your original settings for each parameter (from the manual or from backup photos) so you can re‑enter them if needed.
Troubleshooting Display Issues
| Issue | Likely Cause | Quick Fix |
|---|---|---|
| Screen blank, no power | Battery not seated or main fuse blown | Reseat battery; check fuse in battery holder. |
| Menu won’t open | Wrong button combination or display firmware | Try MODE + UP instead of UP + DOWN. |
| Speed reads double | Wheel size setting too small | Increase P01 by 1–2 inches. |
| Error code “E05” | Throttle fault (short or disconnect) | Unplug throttle, check wiring for damage. |
| Error code “E07” | Motor hall sensor fault | Inspect the motor connector; if pins are bent, straighten carefully. |
| Display resets randomly | Loose connector at the controller end | Push the 5‑pin plug firmly into the controller socket and secure with zip tie. |
If the original Mokwheel display fails and a replacement isn’t available, a universal 5‑pin LCD display can work provided the controller protocol matches. Below is a compatible option.
Aftermarket Display Option (Universal)
When your stock Mokwheel display dies or you need a backup, a universal 5‑pin LCD display may be compatible if the controller uses a standard protocol (often labeled “No. 2 protocol”).
| Product | Brand | Voltages Supported | Handlebar Size | Notes |
|---|---|---|---|---|
| Bike Display LCD 5 Pin M5 Control Panel Bike Screen 24V 36V 48V 60V Universal Scooters Electric Meter Panel Bikes 22.2 31.8mm Handlebars Display to Enrich Cycling Journey (No. 2 Protocol) | GEERYZHE | 24V–60V | 22.2 mm and 31.8 mm | Universal No. 2 protocol; check your controller’s connector pinout before buying. |
Top Pick: The GEERYZHE universal display covers the voltage range most Mokwheel models use and fits common handlebar diameters. Before ordering, confirm your controller uses the No. 2 protocol by checking the small sticker on the controller casing. If uncertain, consult your bike’s support page or a local e‑bike shop.
Final Checks
After adjusting any parameter, test the bike in a safe area. Note that changing the wheel size or speed limit can affect range and battery longevity – higher speeds drain the battery faster. For dual-battery Mokwheel models (like the Obsidian), ensure both packs are fully charged before adjusting hard parameters such as voltage or current limit. Keep a record of your original settings in case you need to revert. If you encounter persistent error codes or the display refuses to save changes, the controller’s memory may be corrupted; try the factory reset procedure above before ordering replacement parts.
