Gazelle Crank Bolt BZK M15x1x13,4 Bosch

The Gazelle crank bolt is a specialized fixing bolt designed to secure the crank arm to the Bosch motor axle on compatible Gazelle e-bikes. With its M15 x 1 fine thread and 13.4 mm length, it ensures the correct engagement and clamping force needed to keep the crank firmly in place, even under high e-bike torque. Manufactured to Bosch/Gazelle specifications, this bolt is the ideal choice when the original fastener is rounded, damaged, or missing after crank removal. Using the proper crank bolt helps prevent unwanted play, creaking, and premature wear at the motor–crank interface, restoring a safe and solid pedaling experience.
