Clarus Lead
This recall concerns a critical safety flaw in the drivetrain system of e-bikes that poses immediate accident risks to users. The coordination between manufacturer and state accident prevention underscores the severity of the defect. Affected owners must immediately remove their bicycles from service and initiate a free replacement of the crank arms.
Detailed Summary
The failure pattern of the Acid-Carbon-Hybrid crank arms is concentrated on the pedal attachment – a highly stressed zone during pedaling. Sudden breakage of this component leads to immediate loss of control and thus fall hazard with potential for serious injuries.
The recall covers exclusively e-bike models from model year 2026 that were delivered before May 8, 2026. Cube provides detailed information on its website for identifying affected models. The repair is performed by specialists and is free of charge for customers. Contact details and further information are available via the Cube website or by email at [email protected].
