This only affects an early production batch of just over 1,600 VanMoof S3 & X3 bikes. If we did not contact you on October 23, there is no reason to be concerned – you can keep riding your bike as usual. If you didn't receive this email but still want to double-check, you can enter your S3 or X3 frame number here. We'll check its production batch to see if your bike is potentially affected.
