While most Bluetooth comm systems can wirelessly link up two riders, the Cardo G4s can connect as many as four. Officially, the G4 provides three-way communication with Rider 1 paired with Rider 2 on Channel A and paired with Rider 3 on Channel B. In this configuration, Cardo claims a 1-mile range between riders, which we verified on our trip to the USGP at Laguna Seca earlier this year.
The system can be tricked into linking four riders by Rider 1 pairing with Rider 2 on Channel A and pairing with Rider 3 on Channel B, while Rider 3 is paired to Rider 4 on Channel A and paired to Rider 2 on Channel B. This way Rider 1 and Rider 4 can communicate with each other via the paired connection between Riders 2 and 3. This configuration is intended to serve a pair of two-up riders, so its range is said to be only 35 feet, but we remained linked up at far greater distances.
