OX 250104 Error Code

Hoping for some help here before I contact my dealer. My ST1X has less than 700 miles on it and now has the error code shown above.

When I power on the bike and roll it forward it self powers for an instant which sets the code. As the rear wheel rolls it also makes a rubbing sound partially through its rotation. I’ve removed the battery hoping for a reset but that has not helped. The bike still works perfect other than the initial error when starting my ride.

My local Stromer dealer doesn’t do any service work, they use Velofix which is a mobile repair service. Any insight would be appreciated.

Thanks

Just wanted to add more information.

If I turn on the power, lift the rear wheel off the ground and move it by hand it will spin to a very high RPM instantly, pretty unsettling. I had to grab the rear brake to stop it.

Loosen the rear axle and reseat it. Somehow, the controller is signalling the motor to spin fast. That signal is tied to what it is seeing from the torque sensor.
Also, calibrate your torque sensor on the OMNI. These steps should help. Your manual (google it) should help you with these.

Thanks for the reply Ravi. I’ll try that and post the result.

Thanks a million for the tip. My rear wheel was slightly loose. Tightened it up with my hex tool and everything seems to be back to normal. So relieved. :)
