Which drive system does my Cowboy e-bike use?
Cowboy fits its own rear hub motor system across the range, so the drive layout is the same regardless of which frame you own. Because the brand designs the motor in-house and pairs it with the Cowboy app instead of a handlebar display, there is no separate badge on the frame that changes how faults are reported. Cowboy does not publish a numeric error code list: when something is wrong, the app surfaces the fault message on your phone. To narrow down a problem, work from the app screen, the rear hub markings and the type plate on the frame.
How to check on your own bike
- Look at the rear hub on the back wheel and read any text or part number printed on the motor casing.
- Confirm there is no handlebar display fitted: on a Cowboy the dashboard lives in the phone app, not on the bike.
- Open the Cowboy app on the paired phone and check the bike name, firmware version and any active fault notification.
- Read the type plate or sticker on the frame down tube or seat tube for the model designation and approval code.
- Cross-check the model name against the invoice or original paperwork so the bike matches the system on file.

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 Cowboy use?
Cowboy builds its own rear hub motor and fits it across its urban e-bike range. There is no third-party drive system on a Cowboy, so identification is about confirming the rear hub and the app pairing rather than matching a Bosch, Shimano or Yamaha badge.
Why does my Cowboy not show an error code number?
Cowboy does not publish a numeric error code list. The motor has no display of its own, so faults are reported as plain text messages inside the Cowboy app on the connected phone.
Where do I see a Cowboy fault message?
Fault messages appear inside the Cowboy app on the phone that is paired with the bike. If the bike will not pair, charge the phone, move closer to the rear hub and re-open the app to read the most recent report.
