Aventon Level.2, Pace, Sinch and Aventure: error 23 or 24, motor phase or hall fault

Codes 23 and 24 on Aventon hub drive bikes mean a motor phase or hall fault. Reseat and inspect the rear motor cable first, then contact Aventon about the cable, controller or motor.

The display on your Aventon shows 23 or 24 and the motor stutters, vibrates, cuts in and out or won't drive at all. On the Level.2, Pace 350 and Pace 500, Sinch and Aventure, 23 is a motor phase fault and 24 is a motor hall fault (Level.2 manual, Pace 350 and 500 manual, Sinch manual, Aventure manual). For any code, stop riding and contact Aventon. Short answer: before that, reseat and inspect the rear motor cable, since a loose or damaged motor plug wire is the first cause to check when the motor won't respond (Level.2 manual).

These codes involve the motor's power and sensor wiring. Do only the visual and plug checks with the bike off, don't ride while the code persists, and leave anything inside the motor or controller to Aventon or a pro.

Most likely cause

E23 and E24 go together on Aventon's hub drive bikes (Aventon help center, related articles). E24 means a motor cable that isn't connected properly, a damaged motor or controller cable, or a damaged hall sensor inside the motor. E23 means a damaged motor phase or a controller putting out abnormal voltage. Either can cause power loss, vibration or irregular running (Electric Kicks E23 and E24). The hall wires run through the cable past the axle, where crushing or rubbing can break a hall signal even though the sensor itself is healthy (EM3ev hall guide).

Other causes to rule out

  • A motor plug that wasn't fully reconnected after a flat or wheel removal. Loose wiring and a loose motor plug wire are causes of a motor that doesn't respond (Sinch manual).
  • A damaged motor. This is the final cause, with repair or replacement as the fix (Pace 350 and 500 manual).
  • Overheating or current protection on a long climb, which shows as 21 or 26 instead. See Aventon error 21 or W03 on climbs.

How to confirm

  1. Note the exact code and when it appears.
  2. Power off and remove the battery.
  3. Find the motor cable where it leaves the rear axle and follow it to its plug. Unplug it, look for grit, water or bent pins, and reconnect it firmly (Electric Kicks E23 and E24). See inspect and clean connectors.
  4. Look along the cable for cuts, worn insulation or pinched spots, especially near the axle and dropout (EM3ev hall guide).
  5. Restart. If the code clears, keep an eye on it. If it stays, or comes and goes when the cable moves, stop riding and contact Aventon with photos and a short video of the motor and display (Electric Kicks E23 and E24).

A hall signal test means probing live pins with the controller powered, so it's a job for a shop (ebikes.ca hall testing).

Fix options

Reseat and reroute the motor cable (easy)

Free, and the first fix for a motor that won't respond is to secure or replace the motor plug wire (Level.2 manual).

Replace the motor cable or controller (pro or Aventon)

The motor cable, controller cable and controller are among the parts that can cause these codes. Don't open sealed electrical parts yourself (Electric Kicks E23 and E24). Contact Aventon for the right part for your model.

Repair hall sensors (pro, needs soldering and electrical experience)

A tech removes the stator, solders in a new sensor and seals it (ebikes.ca hall replacement). This is not an owner repair.

Replace the motor (moderate to pro)

Repair or replacement of a damaged motor is the last step (Aventure manual). Swapping a complete motor wheel is mostly wheel removal work, shown in Aventon's own videos for newer models below. See fix a flat on a rear hub motor wheel.

Parts

  • Motor cable (through Aventon)
  • Rear hub motor or motor wheel (through Aventon)
  • Controller (through Aventon)
