Which Giant e-bike motor system do I have?
Giant, Liv and Momentum e-bikes all use Giant's SyncDrive motor system, so any Giant-badged bike fits this category. The current line-up is the SyncDrive Core at 55 Nm, SyncDrive Sport 2 at 75 Nm and SyncDrive Pro 2 at 85 Nm, with the Pro and Pro 2 units co-developed with Yamaha. The frame badge confirms the brand but not the motor generation, so error codes have to be matched against the specific SyncDrive unit fitted. Before consulting the list, identify which SyncDrive motor is on your bike, which RideControl display is fitted and which app pairs with it.
How to check on your own bike
- Look at the motor casing on the bottom bracket area and read the SyncDrive label, noting the variant (Core, Sport 2 or Pro 2) and the torque figure printed on it.
- Check the handlebar unit: Giant e-bikes use a Giant RideControl display, not a Yamaha interface, so the buttons and screen layout are Giant branded.
- Pair the bike with the Giant RideControl app on a phone and note the exact model name the app reports for the motor and battery.
- Read the type plate, frame sticker or VIN area for the model code and component list, then cross-check it against the original dealer invoice or handover sheet.
- Compare what is written on the motor, on the display, in the app and on the paperwork so the four sources agree before consulting an error code list.

A recall on this list does not mean your bike is affected: check the model and the production dates in the official notice. This list combines the EU Safety Gate, the European Commission rapid alert system, with the U.S. Consumer Product Safety Commission. A model can be sold under another name in another market, so always check the model and production dates in the official notice.
Frequently asked
Which motor does Giant use?
Giant uses its own SyncDrive motor system across Giant, Liv and Momentum e-bikes. The current range is SyncDrive Core (55 Nm), SyncDrive Sport 2 (75 Nm) and SyncDrive Pro 2 (85 Nm), with the Pro and Pro 2 units co-developed with Yamaha.
Is the display on a Giant e-bike made by Giant or Yamaha?
Giant e-bikes use Giant RideControl displays, not Yamaha units, even on motors that are co-developed with Yamaha.
Why do error codes differ between two Giant bikes of the same badge?
Error codes are tied to the specific SyncDrive generation and the RideControl display fitted, so the frame badge alone does not determine which fault list applies.
