Super73 guides
- Super73 MZFT: display shows two white lines and two green lines and seems frozenTroubleshootingOn a Super73 MZFT, a display showing two white and two green horizontal lines and not responding is usually in Bluetooth mode, often from holding the down button at power on. Restart without touching the button.
- Super73 R, S and Z series: display on, but the motor won't run or cuts outTroubleshootingOn Super73 R, S and Z series bikes, a brake motor cut-off sensor that is out of adjustment can stop the bike from running. Check connections and firmware, then adjust the sensor as Super73 describes, and confirm braking still cuts the motor.
- Super73 S2: front fork leaks oil, won't hold air or keeps bottoming outTroubleshootingOn a Super73 S2, a fork that leaks oil, loses air or bottoms out often points to failed seals. Set pressure for your weight with a shock pump first; if it still fails, Super73 says the fix is a full fork replacement.
- Super73 troubleshooting: common problems and safe checksTroubleshootingSafe checks for common Super73 problems, including power and connection issues, charger lights, motor cut off sensors, lights and noisy brakes, plus when to get a pro.
- Super73: charger light flashes red, or stays green and the battery won't fillTroubleshootingOn a Super73, a flashing red charger light means a charger fault: stop using it. A light that stays green on the bike, or a battery that won't reach 100%, needs more checks. Some models switch back to red to top off, which is normal.

- Clicking, grinding or squeaking noisesTroubleshootingWhere e-bike noises usually come from: the chain and gears, the brakes, loose bolts, the cranks and bearings, or the motor.
- Display blank, flickering or frozenTroubleshootingThe handlebar display won't show anything, flickers or freezes. Usually a plug, the battery, water or the display itself.
- Display works but no pedal assistTroubleshootingThe display turns on, but the motor doesn't help when you pedal. Check the assist level, the speed sensor and the brake cut-offs.

- E-bike or scooter won't turn onTroubleshootingNothing happens when you press the power button. Work through the battery, the key and the plugs before assuming the worst.
- Motor cuts out or power comes and goesTroubleshootingThe motor stops helping on and off, over bumps or on hills. Usually a loose connection, a brake sensor, heat or a tired battery.
