Ride1Up Core-5, 500 Series, 700 Series and LMT'D: error 23 or 24 after a flat or rear wheel removal

Error 23 or 24 right after a flat fix or wheel removal on a Ride1Up hub motor bike almost always means the motor cable is loose, dirty or pinched. Reseat and route it before buying parts.

You fixed a flat, moved the bike in a car, or pulled the rear wheel for any reason, and now the display shows error 23 or 24 and the motor won't drive, or drives in fits. This page covers Ride1Up bikes that use 23 and 24 this way: the Core-5, 500 Series and Cafe Cruiser with the KD21C display, and the 700 Series and LMT'D with the LMT'D display (KD21C codes, LMT'D codes). Short answer: the rear hub motor cable is unplugged, not fully seated, dirty, or was pinched when the wheel went back in. Code 23 often means the cable wasn't reconnected after wheel removal, and the most common fix for 24 is the 9-pin connection at the right chain stay (error 23 and 24).

Remove the battery before touching the motor plug. If the cable is cut or the insulation is melted, stop and have a pro or Ride1Up support replace it.

Most likely cause

Code 23 is a motor phase error and 24 is a motor communication or hall sensor error. Both trace back to the motor cable. For 24, a phase wire may also be damaged or loose, or the cable damaged where it exits the axle, for example after the wheel was dropped (KD21C codes). On the Core-5, code 23 can appear if you don't reconnect the cable after removing the wheel (Core-5 manual). Wheel removal is exactly when that plug gets unplugged, bent or strained.

Other causes to rule out

  • Cable damage near the axle. Hub motor cables pass close to the axle, dropout and wheel, and damage there can break a hall wire even when the sensor inside is fine (EM3ev hall guide).
  • Heat on long climbs. If you get error 24 often on steep hills, lower the maximum current setting to 15A, and use 18A or less for frequent hill climbing (500 Series and Core-5 display).
  • A stuck display setting. A factory reset sometimes clears the code (error 23 and 24).
  • Rarely, the controller, a frame cable or the stator itself (error 23 and 24).

How to confirm

  1. Power off and remove the battery.
  2. Find the motor connector on the right chain stay. Unplug it, look for grit, water or bent pins, then line up the two arrows and push it together firmly (how to remove the rear wheel).
  3. Check where the cable leaves the axle. Face the axle cutout forward to reduce strain, and never lay the wheel down on the side where the cable exits (how to remove the rear wheel).
  4. Follow the cable past the tire, the chainring and into the frame, looking for cuts or crushing (error 23 and 24).
  5. Secure the cable with a fresh zip tie so it can't rub, refit the battery and test.
  6. If the code returns, reset the display to defaults and test again (500 Series and Core-5 display).
  7. Note whether the code is intermittent, came after a fall or a snag, or only shows on hills. Ride1Up asks these questions before recommending parts (error 23 and 24).

Fix options

Reseat and route the motor cable (easy)

This clears most post flat errors. See inspect and clean connectors and fix a flat on a rear hub motor wheel.

Replace the motor cable (moderate)

Ride1Up sells a motor cable for the 500 Series in ST and XR versions (500 Series parts). For other models, ask Ride1Up support. Routing the new cable to the controller means opening a battery or controller panel.

Replace the stator or rear wheel (moderate to advanced)

If the damage is on the lead that comes out of the axle, Ride1Up treats that as part of the stator (error 23 and 24). Ride1Up sells a stator only option and a full rear wheel for the Core-5, 500 Series, 700 Series, Cafe Cruiser and LMT'D (rear wheel and motor). Repairing that lead by soldering is a pro job.

Parts

  • Motor cable (500 Series ST or XR, others through Ride1Up support)
  • Motor stator or complete rear wheel and motor

When to get a pro

  • Visible cable damage, bent pins you can't straighten, or melted insulation.
  • A code that returns after a careful reseat.
  • Any soldering on the motor lead, and anything inside the controller. See motor cuts out and when to call a pro.
