Himiway Zebra and Cruiser: error 24 motor hall defect, motor stops

Your Himiway Zebra (D5) or Cruiser shows error 24 and the motor stops or won't start. On both bikes, error 24 is a motor hall defect (Zebra manual, Cruiser manual). Both bikes use a brushless geared hub motor. Short answer: start with the motor wire connector near the hub. If the code stays, the fix is a motor replacement through Himiway after-sales (Himiway error codes).

Most likely cause

Hall sensors inside the motor tell the controller where the magnets are, so it can time the power to the windings. With no clean hall signal, the controller shows a fault and stops. The signal runs through thin wires in the motor cable that leaves the axle. Hub motor cables get crushed near the axle, bent sharply or rubbed against the frame, and connector pins can corrode or push back (EM3ev hall guide). The first step is to find the motor wire near the hub motor, disconnect it and reconnect it to restart the motor (Himiway error codes).

The code is not unusual: it can show on a new Cruiser step-through within minutes of a ride, with the motor cutting out (forum thread).

Other causes to rule out

• A motor cable damaged at the axle or dropout, which mimics a failed sensor (EM3ev hall guide).
• A pushed back pin, open wire or short in the connector. Don't replace hall sensors on symptoms alone.
• If you are running the error 30 isolation test, error 24 is expected while the motor is unplugged (Himiway error codes).

How to confirm

1. Power off. Find the motor cable where it leaves the rear axle and follow it to its connector.
2. Look for cuts, flat spots, kinks and rubbed insulation along the way, especially at the dropout.
3. Unplug the connector by its body. Check for bent or pushed back pins, dirt and corrosion. Reconnect it firmly with the alignment marks matched (Himiway error codes). See inspect and clean connectors.
4. Power on with the wheel lifted and try gentle throttle. If the motor runs, recheck after a few rides.
5. If the code changes when the cable is gently moved, the cable is the likely fault (EM3ev hall guide).
6. If error 24 stays, record a short video showing the code. Himiway after-sales needs it with the motor serial number, the bike serial number and the motor connector details (Himiway error codes).

Fix options

Reseat the motor connector (easy)

Free, and the first step. Often enough after a wheel was removed or the bike was dropped.

Replace the motor cable or hall sensors (pro, needs soldering and electrical experience)

Where the cable is damaged near the axle or one sensor has failed, some shops can replace the cable or sensors inside the motor. It means opening the motor and soldering, so it is pro work. It can be worth it on a motor that is otherwise healthy.

Replace the motor (moderate to pro, through Himiway)

Himiway's after-sales team helps replace the motor when the code persists (Himiway error codes). Fitting a new motor wheel means removing the rear wheel, moving over the tire, cassette or freewheel and rotor, and reconnecting the plug. Our guide to fixing a flat on a rear hub motor wheel covers the wheel removal.

Parts

• Motor cable and hall sensors
• Hub motor

When to get a pro

Get help if the cable is visibly damaged, if the code keeps returning, or if the motor runs rough or hot. Himiway's help center has manuals and the ticket form. See also Himiway troubleshooting, motor cuts out and hub motor e-bike troubleshooting.
