  • Mixed traffic (cycles and other vehicles)
  • Shared use cycle paths
  • Cycling path (asphalt or unbound)
  • ZELT loop in mixed traffic


Power consumption:


The inductive ZELT cycle loop has its own external sealed energy source, a 7.2V lithium battery with battery life of 1 year for one or two loops.

When the battery reaches a critical level, a light will flash on the ZELT cycle unit. The Eco-Logger (used to record data from the ZELT cycle loop) has an industry-leading 10-year battery life.




The ZELT cycle loop has been specifically designed to capture and process the unique magnetic signature of a cycle travelling over it.  The sophisticated algorithum is designed to exclude other signals and search for the 15 key criteria that make up the signature of a cycle.  If just one of the 15 critera is not met the signal is rejected.


The ZELT cycle loop detects cycles that have metal in the rim of the wheel.  Some slow moving two wheel scooters may be counted.  Accuracy is 5 % depending on the quality of the installation and the type of traffic flow.
