Just start moving. Start a movement. Set an example. Set boundaries. Be kind to others. Find balance. Screw Perfection. Foster change. Embrace failure. Prioritize your health. Eat well. Work those muscles. Take breaks. Go dancing once in a while. Sit by a campfire. Spend time with family and friends. Watch the sunrise. Enjoy simplicity. Do what you are passionate about. Make it count. Make it yours.

Equipped with STANDARDIZED INTERFACE SYSTEM
Other cable and connector options on demand
Compatible with Gates Carbon Drive products
The Standardized Interface System consists of a standardized cable (cable length: 220 mm) and a standardized connector (Higo Mini Z509 FG Male or Julet L610 AM Female). This cable and connector form the interface. When OEM customers require a different connector or cable length to connect the XCELL RT 3.0 to their controller, they will need an extension cable with a Standardized Interface Systemcompliant connector on one side (Higo Mini Z509 FM Female or Julet L610 AM Male) and their desired controller-compliant connector on the other side. Such extension cables can be sourced globally from several of THUN‘s cooperation partners. Further details are available upon request.
... allows the perfect blend of cable and connector standardization and customization ... drastically reduces lead times ... guarantees availability of spare parts
