HPR50-60 Drive Unit Bolt - V04, 80mm

TQ Systems GmbH HPR50-60 Drive Unit Bolt (V04, 80mm) is the correct-length replacement mounting fastener for securing a TQ HPR50/HPR60 eBike drive unit to the frame. When servicing an HPR system, using the proper motor bolt helps maintain reliable clamp load at the mount interface and supports quiet, consistent operation—without improvising hardware that can compromise fit or installation.

• HPR50/HPR60 application - Intended for motor-to-frame mounting on TQ HPR drive units for OEM-correct fit
• V04 specification - Makes it easier to match the correct position/spec when replacing worn, damaged, or missing mounting hardware
• 80mm length - Correct bolt length helps achieve proper engagement for a secure drive unit installation
• Service-friendly replacement - Ideal for maintenance, motor removals, or frame service where original bolts should be replaced rather than reused
