Super73 App & Controller Guide: Settings, Modes & Firmware Updates
Super73 App & Controller Guide: Settings, Modes & Firmware Updates
The Super73 app controls four ride modes—Eco, Mode 1, Mode 2, and Mode 3—each with a distinct pedal-assist curve, throttle response, and top speed. To switch modes, open the app, tap the Ride Settings tab, and select the mode you want. You can also toggle between legal street classes (1, 2, 3) and Off-Road mode from the same screen. This guide walks through every setting, explains firmware updates step by step, and gives you concrete ways to verify that changes actually stuck before you ride.
First-Time Setup: Pairing the App with Your Bike
Before you can adjust anything, pair your phone with the bike. Preparation matters here: skipping a step is the most common reason the app fails to find the bike.
What you’ll need:
– Phone with Bluetooth 4.0 or newer (most smartphones from the last 5 years)
– Super73 with battery charged above 50%
– Approve Location permission on Android (the app uses it only for Bluetooth scanning, not tracking)
Steps to pair:
- Download the Super73 app from the iOS App Store or Google Play Store.
- Turn on your Super73 and enable Bluetooth on your phone.
- Open the app. On Android, grant Location permission when prompted.
- Tap Add Bike and select your model. The app scans for nearby bikes.
- When your bike’s name appears, tap it to pair. The dashboard loads with battery level, ride mode, and odometer.
How to verify pairing succeeded: The bike’s display shows a Bluetooth icon (a small dot or “BT” label) once connected. If you don’t see that icon within 30 seconds, restart both the bike and phone, then try again.
How Ride Modes Affect Speed and Range
Each mode targets a different riding priority—range, balance, or full power. The table below maps the default behavior across the four modes. Note that individual model firmware may change these caps slightly.
| Mode | Pedal Assist Behavior | Speed Limit (Street Class) | Best For |
|---|---|---|---|
| Eco | Gentle assist; motor output stays low at all pedal assist levels | 20 mph (Class 2) | Maximizing battery range on flat pavement |
| Mode 1 | Moderate assist; smooth acceleration | 20 mph (Class 2) | Daily commuting and mixed terrain |
| Mode 2 | Stronger assist; quicker throttle response | 20 mph (Class 2) | Rolling hills and faster starts from stops |
| Mode 3 | Maximum assist; full torque from a standstill | 20 mph (Class 2) | Off-road trails, steep climbs, and heavy loads (use Off-Road mode for speeds above 20 mph) |
To switch modes from the handlebar, press the Mode button (if your model has one) or use the app. The change takes effect immediately, and you’ll feel the difference in the first pedal stroke.
Off-Road Mode: When It’s Legal and When It’s Not
Selecting Off-Road in the app removes the 20 mph street limit, letting the motor assist up to 28+ mph (the exact cap depends on your bike’s controller). This mode is intended only for private property or closed courses. On public roads, riding in Off-Road mode can result in fines, impoundment, or liability if you’re in an accident—especially in states that treat e-bikes exceeding Class 3 limits as mopeds requiring registration.
Adjusting Pedal Assist Sensitivity
While ride modes set a fixed speed cap, you can fine-tune how much motor power kicks in per pedal stroke within each mode. This feature, labeled Pedal Assist Tuning in the app, lets you dial the assist curve from mild to aggressive.
How to access it: Open the app > Ride Settings > Pedal Assist Tuning. You’ll see a slider bar for each mode (Eco through Mode 3). The slider sets the motor output percentage at the highest pedal assist level (PAS 5) relative to the mode’s maximum.
Concrete examples of default behavior (varies by model firmware, but this is typical):
- In Eco, PAS 1 might deliver 20% motor output, while PAS 5 stays under 50%.
- In Mode 3, PAS 1 could start at 40% and PAS 5 provides 100%.
Moving the slider down in Mode 3, for instance, makes the bike feel more relaxed even on max assist—helpful if you want the power on tap without a jerky launch. Moving it up in Eco shortens your range noticeably.
Important: PAS tuning only affects the pedal-assist curve, not the speed limit. To raise the speed cap, you must switch to a higher street class or Off-Road mode.
Switching Between Street Classes and Off-Road Mode
U.S. regulations sort e-bikes into three classes:
- Class 1: Pedal assist only, max 20 mph
- Class 2: Throttle and pedal assist, max 20 mph
- Class 3: Pedal assist only, max 28 mph
Your Super73 ships with a default class setting (usually Class 2). To change it:
- Open the app and go to Settings > Class Mode.
- Tap the desired class (1, 2, or 3) or Off-Road.
- Confirm the change. The bike restarts the controller to apply the new limit.
How to verify the change took effect: After the bike restarts, ride for a few seconds. If you selected Class 3, you should be able to pedal to 28 mph before the motor cuts out. If you selected Class 2, the motor assistance stops at 20 mph. If the speed doesn’t match, try closing and reopening the app, then redoing the step.
Why this matters for your daily ride: Many multi-use trails ban Class 3 bikes. Picking the wrong class can get you a ticket or asked to leave. Check local laws before changing classes—especially if you commute through multiple jurisdictions.
Step-by-Step Firmware Update
Super73 releases firmware updates to improve battery management, throttle calibration, and add new features. The update must complete without interruptions—a failed update can corrupt the controller and require dealer service.
Preparation checklist:
– Phone battery above 50% (low-battery shutdown mid-update is the #1 failure cause)
– Bike battery above 50%
– Park the bike on a stable, level surface
– Stay within Bluetooth range (about 3 feet from the handlebar display)
Steps to update:
- Open the app and connect to your bike.
- Go to Settings > Firmware Update. The app checks for available updates.
- If an update is found, tap Update Now. The bike’s display shows “Updating” and the motor may click or beep.
- Do not turn off the bike, close the app, or walk out of Bluetooth range. If the update fails partway, the controller may need reflashing by a technician.
- The process takes 5–10 minutes. When it finishes, the bike restarts automatically.
How to verify the update succeeded:
- After restart, open the app and go to Settings > Firmware Update again. It should now say “Up to date.”
- Ride the bike and test the throttle and pedal assist at a low speed. The bike should feel responsive and behave the same as before (or better, if the update addressed a quirk like jerky throttle).
- If the bike feels sluggish or doesn’t respond at all, try rebooting the battery: remove it, wait 1 minute, reinsert, and reconnect the app. If the problem persists, contact Super73 support.
Troubleshooting Connection Drops and Error Codes
Even after a successful pairing, you may encounter occasional drops or failure to connect while riding. Here are the most common causes and fixes, backed by examples from rider reports.
| Symptom | Likely Cause | Solution |
|---|---|---|
| App says “No Bike Found” | Bluetooth interference or phone in power-saving mode | Disable battery saver on your phone, restart the bike, and open the app again. |
| Connection drops while riding | Phone too far from handlebar display (Bluetooth antenna is inside the display) | Keep your phone within 3 feet of the display, or mount it on the handlebar. |
| Bike appears in app but won’t change modes | Outdated controller firmware | Check for a firmware update in the app (see previous section). |
| Error code E08 on display | Controller communication error | Turn off the bike for 30 seconds, remove the battery, wait 1 minute, then reassemble. If the error persists, contact Super73 support. |
For Android users, a common hidden issue is “battery optimization” for the Super73 app. Go to your phone’s Settings > Apps > Super73 > Battery and set it to Unrestricted. This prevents the system from killing the app’s Bluetooth connection in the background. Without this step, the app often disconnects mid-ride when the phone enters doze mode.
Display Icons at a Glance
Your Super73’s handlebar display shows a set of icons that can be confusing at first. Here’s what each one means:
- Battery icon – Voltage-based charge estimate. One bar means recharge soon; the bike may stop assisting when the battery reaches reserve voltage.
- Speed readout – Current speed in mph or km/h, depending on region setting.
- ODC / Trip – Odometer (total miles) and trip distance. Press the display button to toggle between them.
- Mode indicator – A letter or number for the current ride mode: E for Eco, 1 for Mode 1, etc.
- Headlight icon – Solid when lights are on.
- Error codes – Appear as “E” followed by a number. E01 = throttle fault, E07 = motor hall sensor issue, E08 = controller communication. If an error code flashes, the bike usually stops assisting. Power cycle the bike; if the error returns, check the manual or contact support.
Frequently Asked Questions
Q: Can I change ride modes while riding?
A: Yes. You can switch modes using the handlebar Mode button or the app while the bike is moving. The new mode takes effect immediately.
Q: Will a firmware update erase my custom pedal assist settings?
A: In most cases, yes. Super73’s firmware updates reset the PAS tuning sliders to default. Write down your preferred percentages before updating so you can restore them quickly.
Q: Why does my bike show a higher speed in Off-Road mode but the pedal assist feels weaker?
A: Off-Road mode raises the speed cap but also changes the pedal-assist curve. If you find the assist too weak, check the PAS tuning sliders in the app and increase the percentage for the current mode.
Q: Is it safe to ride with the app closed?
A: Yes. The app is only needed for changing settings and firmware updates. Once you’ve picked your mode and class, you can close the app and ride normally—the bike retains the last settings until you change them again.
Using the Super73 app effectively gives you precise control over your riding experience—from range-maxing commutes to full-power off-road adventures. Keep the app updated, stay within local class laws, and verify each setting change with a short ride test to confirm the bike behaves as expected.
